If this is happening, you may want to change the default journal mode to Persist. + + + + + The default mode, this causes SQLite to use the existing journaling mode for the database. + + + + + SQLite will create and destroy the journal file as-needed. + + + + + When this is set, SQLite will keep the journal file even after a transaction has completed. It's contents will be erased, + and the journal re-used as often as needed. If it is deleted, it will be recreated the next time it is needed. + + + + + This option disables the rollback journal entirely. Interrupted transactions or a program crash can cause database + corruption in this mode! + + + + + SQLite will truncate the journal file to zero-length instead of deleting it. + + + + + SQLite will store the journal in volatile RAM. This saves disk I/O but at the expense of database safety and integrity. + If the application using SQLite crashes in the middle of a transaction when the MEMORY journaling mode is set, then the + database file will very likely go corrupt. + + + + + SQLite uses a write-ahead log instead of a rollback journal to implement transactions. The WAL journaling mode is persistent; + after being set it stays in effect across multiple database connections and after closing and reopening the database. A database + in WAL journaling mode can only be accessed by SQLite version 3.7.0 or later. + + + + + Possible values for the "synchronous" database setting. This setting determines + how often the database engine calls the xSync method of the VFS. + + + + + Use the default "synchronous" database setting. Currently, this should be + the same as using the FULL mode. + + + + + The database engine continues without syncing as soon as it has handed + data off to the operating system. If the application running SQLite + crashes, the data will be safe, but the database might become corrupted + if the operating system crashes or the computer loses power before that + data has been written to the disk surface. + + + + + The database engine will still sync at the most critical moments, but + less often than in FULL mode. There is a very small (though non-zero) + chance that a power failure at just the wrong time could corrupt the + database in NORMAL mode. + + + + + The database engine will use the xSync method of the VFS to ensure that + all content is safely written to the disk surface prior to continuing. + This ensures that an operating system crash or power failure will not + corrupt the database.

The db parameter + is a pointer to the SQLite database connection that is executing + the CREATE VIRTUAL TABLE statement. The pAux argument is the copy + of the client data pointer that was the fourth argument to the + sqlite3_create_module() or sqlite3_create_module_v2() call that + registered the virtual table module. The argv parameter is an + array of argc pointers to null terminated strings. The first + string, argv[0], is the name of the module being invoked. The + module name is the name provided as the second argument to + sqlite3_create_module() and as the argument to the USING clause of + the CREATE VIRTUAL TABLE statement that is running. The second, + argv[1], is the name of the database in which the new virtual table + is being created. The database name is "main" for the primary + database, or "temp" for TEMP database, or the name given at the + end of the ATTACH statement for attached databases. The third + element of the array, argv[2], is the name of the new virtual + table, as specified following the TABLE keyword in the CREATE + VIRTUAL TABLE statement. If present, the fourth and subsequent + strings in the argv[] array report the arguments to the module name + in the CREATE VIRTUAL TABLE statement. + + + The job of this method is to construct the new virtual table object + (an sqlite3_vtab object) and return a pointer to it in *ppVTab. + + + As part of the task of creating a new sqlite3_vtab structure, this + method must invoke sqlite3_declare_vtab() to tell the SQLite core + about the columns and datatypes in the virtual table. The + sqlite3_declare_vtab() API has the following prototype: + + + + int sqlite3_declare_vtab(sqlite3 *db, const char *zCreateTable) + + + + The first argument to sqlite3_declare_vtab() must be the same + database connection pointer as the first parameter to this method. + The second argument to sqlite3_declare_vtab() must a + zero-terminated UTF-8 string that contains a well-formed CREATE + TABLE statement that defines the columns in the virtual table and + their data types. The name of the table in this CREATE TABLE + statement is ignored, as are all constraints. Only the column names + and datatypes matter. The CREATE TABLE statement string need not to + be held in persistent memory. The string can be deallocated and/or + reused as soon as the sqlite3_declare_vtab() routine returns. + + + + The native database connection handle. + + + The original native pointer value that was provided to the + sqlite3_create_module(), sqlite3_create_module_v2() or + sqlite3_create_disposable_module() functions. + + + The number of arguments from the CREATE VIRTUAL TABLE statement. + + + The array of string arguments from the CREATE VIRTUAL TABLE + statement. + + + Upon success, this parameter must be modified to point to the newly + created native sqlite3_vtab derived structure. + + + Upon failure, this parameter must be modified to point to the error + message, with the underlying memory having been obtained from the + sqlite3_malloc() function. + + + A standard SQLite return code. + + + + + + The xConnect method is very similar to xCreate. It has the same + parameters and constructs a new sqlite3_vtab structure just like + xCreate. And it must also call sqlite3_declare_vtab() like xCreate. + + + The difference is that xConnect is called to establish a new + connection to an existing virtual table whereas xCreate is called + to create a new virtual table from scratch. + + + The xCreate and xConnect methods are only different when the + virtual table has some kind of backing store that must be + initialized the first time the virtual table is created. The + xCreate method creates and initializes the backing store. The + xConnect method just connects to an existing backing store. + + + As an example, consider a virtual table implementation that + provides read-only access to existing comma-separated-value (CSV) + files on disk. There is no backing store that needs to be created + or initialized for such a virtual table (since the CSV files + already exist on disk) so the xCreate and xConnect methods will be + identical for that module. + + + Another example is a virtual table that implements a full-text + index. The xCreate method must create and initialize data + structures to hold the dictionary and posting lists for that index. + The xConnect method, on the other hand, only has to locate and use + an existing dictionary and posting lists that were created by a + prior xCreate call. + + + The xConnect method must return SQLITE_OK if it is successful in + creating the new virtual table, or SQLITE_ERROR if it is not + successful. If not successful, the sqlite3_vtab structure must not + be allocated. An error message may optionally be returned in *pzErr + if unsuccessful. Space to hold the error message string must be + allocated using an SQLite memory allocation function like + sqlite3_malloc() or sqlite3_mprintf() as the SQLite core will + attempt to free the space using sqlite3_free() after the error has + been reported up to the application. + + + The xConnect method is required for every virtual table + implementation, though the xCreate and xConnect pointers of the + sqlite3_module object may point to the same function the virtual + table does not need to initialize backing store. + + + + The native database connection handle. + + + The original native pointer value that was provided to the + sqlite3_create_module(), sqlite3_create_module_v2() or + sqlite3_create_disposable_module() functions. + + + The number of arguments from the CREATE VIRTUAL TABLE statement. + + + The array of string arguments from the CREATE VIRTUAL TABLE + statement. + + + Upon success, this parameter must be modified to point to the newly + created native sqlite3_vtab derived structure. + + + Upon failure, this parameter must be modified to point to the error + message, with the underlying memory having been obtained from the + sqlite3_malloc() function. + + + A standard SQLite return code. + + + + + + SQLite uses the xBestIndex method of a virtual table module to + determine the best way to access the virtual table. The xBestIndex + method has a prototype like this: + + + int (*xBestIndex)(sqlite3_vtab *pVTab, sqlite3_index_info*); + + + The SQLite core communicates with the xBestIndex method by filling + in certain fields of the sqlite3_index_info structure and passing a + pointer to that structure into xBestIndex as the second parameter. + The xBestIndex method fills out other fields of this structure + which forms the reply. The sqlite3_index_info structure looks like + this: + + + struct sqlite3_index_info { + /* Inputs */ + const int nConstraint; /* Number of entries in aConstraint */ + const struct sqlite3_index_constraint { + int iColumn; /* Column on left-hand side of + * constraint */ + unsigned char op; /* Constraint operator */ + unsigned char usable; /* True if this constraint is usable */ + int iTermOffset; /* Used internally - xBestIndex should + * ignore */ + } *const aConstraint; /* Table of WHERE clause constraints */ + const int nOrderBy; /* Number of terms in the ORDER BY + * clause */ + const struct sqlite3_index_orderby { + int iColumn; /* Column number */ + unsigned char desc; /* True for DESC. False for ASC. */ + } *const aOrderBy; /* The ORDER BY clause */ + /* Outputs */ + struct sqlite3_index_constraint_usage { + int argvIndex; /* if greater than zero, constraint is + * part of argv to xFilter */ + unsigned char omit; /* Do not code a test for this + * constraint */ + } *const aConstraintUsage; + int idxNum; /* Number used to identify the index */ + char *idxStr; /* String, possibly obtained from + * sqlite3_malloc() */ + int needToFreeIdxStr; /* Free idxStr using sqlite3_free() if + * true */ + int orderByConsumed; /* True if output is already ordered */ + double estimatedCost; /* Estimated cost of using this index */ + }; + + + In addition, there are some defined constants: + + + #define SQLITE_INDEX_CONSTRAINT_EQ 2 + #define SQLITE_INDEX_CONSTRAINT_GT 4 + #define SQLITE_INDEX_CONSTRAINT_LE 8 + #define SQLITE_INDEX_CONSTRAINT_LT 16 + #define SQLITE_INDEX_CONSTRAINT_GE 32 + #define SQLITE_INDEX_CONSTRAINT_MATCH 64 + + + The SQLite core calls the xBestIndex method when it is compiling a + query that involves a virtual table. In other words, SQLite calls + this method when it is running sqlite3_prepare() or the equivalent. + By calling this method, the SQLite core is saying to the virtual + table that it needs to access some subset of the rows in the + virtual table and it wants to know the most efficient way to do + that access. The xBestIndex method replies with information that + the SQLite core can then use to conduct an efficient search of the + virtual table. + + + While compiling a single SQL query, the SQLite core might call + xBestIndex multiple times with different settings in + sqlite3_index_info. The SQLite core will then select the + combination that appears to give the best performance. + + + Before calling this method, the SQLite core initializes an instance + of the sqlite3_index_info structure with information about the + query that it is currently trying to process. This information + derives mainly from the WHERE clause and ORDER BY or GROUP BY + clauses of the query, but also from any ON or USING clauses if the + query is a join. The information that the SQLite core provides to + the xBestIndex method is held in the part of the structure that is + marked as "Inputs". The "Outputs" section is initialized to zero. + + + The information in the sqlite3_index_info structure is ephemeral + and may be overwritten or deallocated as soon as the xBestIndex + method returns. If the xBestIndex method needs to remember any part + of the sqlite3_index_info structure, it should make a copy. Care + must be take to store the copy in a place where it will be + deallocated, such as in the idxStr field with needToFreeIdxStr set + to 1. + + + Note that xBestIndex will always be called before xFilter, since + the idxNum and idxStr outputs from xBestIndex are required inputs + to xFilter. However, there is no guarantee that xFilter will be + called following a successful xBestIndex. + + + The xBestIndex method is required for every virtual table + implementation. + + + 2.3.1 Inputs + + + The main thing that the SQLite core is trying to communicate to the + virtual table is the constraints that are available to limit the + number of rows that need to be searched. The aConstraint[] array + contains one entry for each constraint. There will be exactly + nConstraint entries in that array. + + + Each constraint will correspond to a term in the WHERE clause or in + a USING or ON clause that is of the form + + + column OP EXPR + + + Where "column" is a column in the virtual table, OP is an operator + like "=" or "<", and EXPR is an arbitrary expression. So, for + example, if the WHERE clause contained a term like this: + + + a = 5 + + + Then one of the constraints would be on the "a" column with + operator "=" and an expression of "5". Constraints need not have a + literal representation of the WHERE clause. The query optimizer + might make transformations to the WHERE clause in order to extract + as many constraints as it can. So, for example, if the WHERE clause + contained something like this: + + + x BETWEEN 10 AND 100 AND 999>y + + + The query optimizer might translate this into three separate + constraints: + + + x >= 10 + x <= 100 + y < 999 + + + For each constraint, the aConstraint[].iColumn field indicates + which column appears on the left-hand side of the constraint. The + first column of the virtual table is column 0. The rowid of the + virtual table is column -1. The aConstraint[].op field indicates + which operator is used. The SQLITE_INDEX_CONSTRAINT_* constants map + integer constants into operator values. Columns occur in the order + they were defined by the call to sqlite3_declare_vtab() in the + xCreate or xConnect method. Hidden columns are counted when + determining the column index. + + + The aConstraint[] array contains information about all constraints + that apply to the virtual table. But some of the constraints might + not be usable because of the way tables are ordered in a join. The + xBestIndex method must therefore only consider constraints that + have an aConstraint[].usable flag which is true. + + + In addition to WHERE clause constraints, the SQLite core also tells + the xBestIndex method about the ORDER BY clause. (In an aggregate + query, the SQLite core might put in GROUP BY clause information in + place of the ORDER BY clause information, but this fact should not + make any difference to the xBestIndex method.) If all terms of the + ORDER BY clause are columns in the virtual table, then nOrderBy + will be the number of terms in the ORDER BY clause and the + aOrderBy[] array will identify the column for each term in the + order by clause and whether or not that column is ASC or DESC. + + + 2.3.2 Outputs + + + Given all of the information above, the job of the xBestIndex + method it to figure out the best way to search the virtual table. + + + The xBestIndex method fills the idxNum and idxStr fields with + information that communicates an indexing strategy to the xFilter + method. The information in idxNum and idxStr is arbitrary as far as + the SQLite core is concerned. The SQLite core just copies the + information through to the xFilter method. Any desired meaning can + be assigned to idxNum and idxStr as long as xBestIndex and xFilter + agree on what that meaning is. + + + The idxStr value may be a string obtained from an SQLite memory + allocation function such as sqlite3_mprintf(). If this is the case, + then the needToFreeIdxStr flag must be set to true so that the + SQLite core will know to call sqlite3_free() on that string when it + has finished with it, and thus avoid a memory leak. + + + If the virtual table will output rows in the order specified by the + ORDER BY clause, then the orderByConsumed flag may be set to true. + If the output is not automatically in the correct order then + orderByConsumed must be left in its default false setting. This + will indicate to the SQLite core that it will need to do a separate + sorting pass over the data after it comes out of the virtual table. + + + The estimatedCost field should be set to the estimated number of + disk access operations required to execute this query against the + virtual table. The SQLite core will often call xBestIndex multiple + times with different constraints, obtain multiple cost estimates, + then choose the query plan that gives the lowest estimate. + + + The aConstraintUsage[] array contains one element for each of the + nConstraint constraints in the inputs section of the + sqlite3_index_info structure. The aConstraintUsage[] array is used + by xBestIndex to tell the core how it is using the constraints. + + + The xBestIndex method may set aConstraintUsage[].argvIndex entries + to values greater than one. Exactly one entry should be set to 1, + another to 2, another to 3, and so forth up to as many or as few as + the xBestIndex method wants. The EXPR of the corresponding + constraints will then be passed in as the argv[] parameters to + xFilter. + + + For example, if the aConstraint[3].argvIndex is set to 1, then when + xFilter is called, the argv[0] passed to xFilter will have the EXPR + value of the aConstraint[3] constraint. + + + By default, the SQLite core double checks all constraints on each + row of the virtual table that it receives. If such a check is + redundant, the xBestFilter method can suppress that double-check by + setting aConstraintUsage[].omit. + + + + The native pointer to the sqlite3_vtab derived structure. + + + The native pointer to the sqlite3_index_info structure. + + + A standard SQLite return code. + + + + + + This method releases a connection to a virtual table. Only the + sqlite3_vtab object is destroyed. The virtual table is not + destroyed and any backing store associated with the virtual table + persists. This method undoes the work of xConnect. + + + This method is a destructor for a connection to the virtual table. + Contrast this method with xDestroy. The xDestroy is a destructor + for the entire virtual table. + + + The xDisconnect method is required for every virtual table + implementation, though it is acceptable for the xDisconnect and + xDestroy methods to be the same function if that makes sense for + the particular virtual table. + + + + The native pointer to the sqlite3_vtab derived structure. + + + A standard SQLite return code. + + + + + + This method releases a connection to a virtual table, just like the + xDisconnect method, and it also destroys the underlying table + implementation. This method undoes the work of xCreate. + + + The xDisconnect method is called whenever a database connection + that uses a virtual table is closed. The xDestroy method is only + called when a DROP TABLE statement is executed against the virtual + table. + + + The xDestroy method is required for every virtual table + implementation, though it is acceptable for the xDisconnect and + xDestroy methods to be the same function if that makes sense for + the particular virtual table. + + + + The native pointer to the sqlite3_vtab derived structure. + + + A standard SQLite return code. + + + + + + The xOpen method creates a new cursor used for accessing (read + and/or writing) a virtual table. A successful invocation of this + method will allocate the memory for the sqlite3_vtab_cursor (or a + subclass), initialize the new object, and make *ppCursor point to + the new object. The successful call then returns SQLITE_OK. + + + For every successful call to this method, the SQLite core will + later invoke the xClose method to destroy the allocated cursor. + + + The xOpen method need not initialize the pVtab field of the + sqlite3_vtab_cursor structure. The SQLite core will take care of + that chore automatically. + + + A virtual table implementation must be able to support an arbitrary + number of simultaneously open cursors. + + + When initially opened, the cursor is in an undefined state. The + SQLite core will invoke the xFilter method on the cursor prior to + any attempt to position or read from the cursor. + + + The xOpen method is required for every virtual table + implementation. + + + + The native pointer to the sqlite3_vtab derived structure. + + + Upon success, this parameter must be modified to point to the newly + created native sqlite3_vtab_cursor derived structure. + + + A standard SQLite return code. + + + + + + The xClose method closes a cursor previously opened by xOpen. The + SQLite core will always call xClose once for each cursor opened + using xOpen. + + + This method must release all resources allocated by the + corresponding xOpen call. The routine will not be called again even + if it returns an error. The SQLite core will not use the + sqlite3_vtab_cursor again after it has been closed. + + + The xClose method is required for every virtual table + implementation. + + + + The native pointer to the sqlite3_vtab_cursor derived structure. + + + A standard SQLite return code. + + + + + + This method begins a search of a virtual table. The first argument + is a cursor opened by xOpen. The next two argument define a + particular search index previously chosen by xBestIndex. The + specific meanings of idxNum and idxStr are unimportant as long as + xFilter and xBestIndex agree on what that meaning is. + + + The xBestIndex function may have requested the values of certain + expressions using the aConstraintUsage[].argvIndex values of the + sqlite3_index_info structure. Those values are passed to xFilter + using the argc and argv parameters. + + + If the virtual table contains one or more rows that match the + search criteria, then the cursor must be left point at the first + row. Subsequent calls to xEof must return false (zero). If there + are no rows match, then the cursor must be left in a state that + will cause the xEof to return true (non-zero). The SQLite engine + will use the xColumn and xRowid methods to access that row content. + The xNext method will be used to advance to the next row. + + + This method must return SQLITE_OK if successful, or an sqlite error + code if an error occurs. + + + The xFilter method is required for every virtual table + implementation. + + + + The native pointer to the sqlite3_vtab_cursor derived structure. + + + Number used to help identify the selected index. + + + The native pointer to the UTF-8 encoded string containing the + string used to help identify the selected index. + + + The number of native pointers to sqlite3_value structures specified + in . + + + An array of native pointers to sqlite3_value structures containing + filtering criteria for the selected index. + + + A standard SQLite return code. + + + + + + The xNext method advances a virtual table cursor to the next row of + a result set initiated by xFilter. If the cursor is already + pointing at the last row when this routine is called, then the + cursor no longer points to valid data and a subsequent call to the + xEof method must return true (non-zero). If the cursor is + successfully advanced to another row of content, then subsequent + calls to xEof must return false (zero). + + + This method must return SQLITE_OK if successful, or an sqlite error + code if an error occurs. + + + The xNext method is required for every virtual table + implementation. + + + + The native pointer to the sqlite3_vtab_cursor derived structure. + + + A standard SQLite return code. + + + + + + The xEof method must return false (zero) if the specified cursor + currently points to a valid row of data, or true (non-zero) + otherwise. This method is called by the SQL engine immediately + after each xFilter and xNext invocation. + + + The xEof method is required for every virtual table implementation. + + + + The native pointer to the sqlite3_vtab_cursor derived structure. + + + Non-zero if no more rows are available; zero otherwise. + + + + + + The SQLite core invokes this method in order to find the value for + the N-th column of the current row. N is zero-based so the first + column is numbered 0. The xColumn method may return its result back + to SQLite using one of the following interface: + + + sqlite3_result_blob() + sqlite3_result_double() + sqlite3_result_int() + sqlite3_result_int64() + sqlite3_result_null() + sqlite3_result_text() + sqlite3_result_text16() + sqlite3_result_text16le() + sqlite3_result_text16be() + sqlite3_result_zeroblob() + + + If the xColumn method implementation calls none of the functions + above, then the value of the column defaults to an SQL NULL. + + + To raise an error, the xColumn method should use one of the + result_text() methods to set the error message text, then return an + appropriate error code. The xColumn method must return SQLITE_OK on + success. + + + The xColumn method is required for every virtual table + implementation. + + + + The native pointer to the sqlite3_vtab_cursor derived structure. + + + The native pointer to the sqlite3_context structure to be used + for returning the specified column value to the SQLite core + library. + + + The zero-based index corresponding to the column containing the + value to be returned. + + + A standard SQLite return code. + + + + + + A successful invocation of this method will cause *pRowid to be + filled with the rowid of row that the virtual table cursor pCur is + currently pointing at. This method returns SQLITE_OK on success. It + returns an appropriate error code on failure. + + + The xRowid method is required for every virtual table + implementation. + + + + The native pointer to the sqlite3_vtab_cursor derived structure. + + + Upon success, this parameter must be modified to contain the unique + integer row identifier for the current row for the specified cursor. + + + A standard SQLite return code. + + + + + + All changes to a virtual table are made using the xUpdate method. + This one method can be used to insert, delete, or update. + + + The argc parameter specifies the number of entries in the argv + array. The value of argc will be 1 for a pure delete operation or + N+2 for an insert or replace or update where N is the number of + columns in the table. In the previous sentence, N includes any + hidden columns. + + + Every argv entry will have a non-NULL value in C but may contain + the SQL value NULL. In other words, it is always true that + argv[i]!=0 for i between 0 and argc-1. However, it might be the + case that sqlite3_value_type(argv[i])==SQLITE_NULL. + + + The argv[0] parameter is the rowid of a row in the virtual table + to be deleted. If argv[0] is an SQL NULL, then no deletion occurs. + + + The argv[1] parameter is the rowid of a new row to be inserted into + the virtual table. If argv[1] is an SQL NULL, then the + implementation must choose a rowid for the newly inserted row. + Subsequent argv[] entries contain values of the columns of the + virtual table, in the order that the columns were declared. The + number of columns will match the table declaration that the + xConnect or xCreate method made using the sqlite3_declare_vtab() + call. All hidden columns are included. + + + When doing an insert without a rowid (argc>1, argv[1] is an SQL + NULL), the implementation must set *pRowid to the rowid of the + newly inserted row; this will become the value returned by the + sqlite3_last_insert_rowid() function. Setting this value in all the + other cases is a harmless no-op; the SQLite engine ignores the + *pRowid return value if argc==1 or argv[1] is not an SQL NULL. + + + Each call to xUpdate will fall into one of cases shown below. Note + that references to argv[i] mean the SQL value held within the + argv[i] object, not the argv[i] object itself. + + + argc = 1 + + + The single row with rowid equal to argv[0] is deleted. No + insert occurs. + + + argc > 1 + argv[0] = NULL + + + A new row is inserted with a rowid argv[1] and column + values in argv[2] and following. If argv[1] is an SQL NULL, + the a new unique rowid is generated automatically. + + + argc > 1 + argv[0] ? NULL + argv[0] = argv[1] + + + The row with rowid argv[0] is updated with new values in + argv[2] and following parameters. + + + argc > 1 + argv[0] ? NULL + argv[0] ? argv[1] + + + The row with rowid argv[0] is updated with rowid argv[1] + and new values in argv[2] and following parameters. This + will occur when an SQL statement updates a rowid, as in + the statement: + + + UPDATE table SET rowid=rowid+1 WHERE ...; + + + The xUpdate method must return SQLITE_OK if and only if it is + successful. If a failure occurs, the xUpdate must return an + appropriate error code. On a failure, the pVTab->zErrMsg element + may optionally be replaced with error message text stored in memory + allocated from SQLite using functions such as sqlite3_mprintf() or + sqlite3_malloc(). + + + If the xUpdate method violates some constraint of the virtual table + (including, but not limited to, attempting to store a value of the + wrong datatype, attempting to store a value that is too large or + too small, or attempting to change a read-only value) then the + xUpdate must fail with an appropriate error code. + + + There might be one or more sqlite3_vtab_cursor objects open and in + use on the virtual table instance and perhaps even on the row of + the virtual table when the xUpdate method is invoked. The + implementation of xUpdate must be prepared for attempts to delete + or modify rows of the table out from other existing cursors. If the + virtual table cannot accommodate such changes, the xUpdate method + must return an error code. + + + The xUpdate method is optional. If the xUpdate pointer in the + sqlite3_module for a virtual table is a NULL pointer, then the + virtual table is read-only. + + + + The native pointer to the sqlite3_vtab derived structure. + + + The number of new or modified column values contained in + . + + + The array of native pointers to sqlite3_value structures containing + the new or modified column values, if any. + + + Upon success, this parameter must be modified to contain the unique + integer row identifier for the row that was inserted, if any. + + + A standard SQLite return code. + + + + + + This method begins a transaction on a virtual table. This is method + is optional. The xBegin pointer of sqlite3_module may be NULL. + + + This method is always followed by one call to either the xCommit or + xRollback method. Virtual table transactions do not nest, so the + xBegin method will not be invoked more than once on a single + virtual table without an intervening call to either xCommit or + xRollback.
