Executing multiple SQL operations in a single transaction

Using default Methods with the SqlObject mixin COUNT() counts all the rows in the target table whether they include nulls or not. Mapping arguments to Java parameter names Query profiling can be disabled using '.scanstats off'. Once enabled, the shell automatically outputs a query profile after each SQL query executed. Mapping arguments to positional parameters Within a command-line shell compiled with the option above, query profiling is enabled using the '.scanstats on' command: sqlite>. CREATE TRIGGER updatesummary AFTER INSERT ON Data BEGIN INSERT INTO Datasummary (type, dataid, totalcount) - If Insert is success this is a new value of type so. (but I give actual details in my answer of a working example).

Mapping result types with latent operations 1) Update the summary table using a Trigger as suggested by stephenmwyatt22-w. Attaching statements to the handle lifecycle The PRAGMA command is issued using the same interface as other SQLite commands (e.g. Development documentation (3.42.0-SNAPSHOT) The PRAGMA command is a special command used to modify the operation of the SQLite library or to query the library for internal (non-table) data.When no rows match an aggregate query, the xStep() callback of the aggregate function implementation is never called and xFinal() is called exactly once. $sth = $pdh -> query ( 'SELECT * FROM sys.tables' ) Sqlite3aggregatecontext() is normally called once for each invocation of the xStep callback and then one last time when the xFinal callback is invoked. $pdh = new myPDO ( $dsn, $db_user, $db_pass ) $res = ( $values ) ? $sth -> execute ( $values ) : $sth -> execute () SQLite COUNT is an aggregate function that returns the number of items in a group. prepare ( $query, array( PDO :: ATTR_CURSOR => PDO :: CURSOR_SCROLL ))) Since SQLite3 sufferes no such problem because the database is 'in process', the 'stored procedure' is called a 'subroutine' and is part and parcel of the application itself.

In some drivers rowCount() only works when using the prepare() with PDO::CURSOR_SCROLL The procedure is precompiled and 'stored' on the server so that the latency of a myriad of line turnarounds are avoided.
