(No version information available, might be only in CVS)
SQLiteDatabase->exec — Executes a result-less query against a given database
Descrierea
Object oriented style (method):
Executes an SQL statement given by the query against a given database handle (specified by the dbhandle parameter).
SQLite will execute multiple queries separated by semicolons, so you can use it to execute a batch of SQL that you have loaded from a file or have embedded in a script.
Parametri
- dbhandle
-
The SQLite Database resource; returned from sqlite_open() when used procedurally. This parameter is not required when using the object-oriented method.
- query
-
The query to be executed.
- error_msg
-
The specified variable will be filled if an error occurs. This is specially important because SQL syntax errors can't be fetched using the sqlite_last_error() function.
Notă: Două sintaxe alternative sunt susţinute pentru compatibilitate cu alte extensii de baze de date (cum ar fi MySQL). Forma preferată este cae dintâi, unde parametrul dbhandle este primul parametru pentru funcţie.
Valorile întroarse
This function will return a boolean result; TRUE for success or FALSE for failure. If you need to run a query that returns rows, see sqlite_query().
În denumirile coloanelor întoarse de SQLITE_ASSOC şi SQLITE_BOTH vor fi utilizate litere majuscule/minuscule în corespundere cu valoarea opţiunii de configurare sqlite.assoc_case.
