sqlite_exec

SQLiteDatabase::exec

Executes a result-less query against a given database

Description

bool sqlite_exec ( resource $dbhandle , string $query [, string &$error_msg ] )
bool sqlite_exec ( string $query , resource $dbhandle )

Object oriented style (method):

public bool SQLiteDatabase::queryExec ( string $query [, string &$error_msg ] )

Executes an SQL statement given by the query against a given database handle (specified by the dbhandle parameter).

Warning

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.

Parameters

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.

Data inside the query should be properly escaped.

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.

Note: Two alternative syntaxes are supported for compatibility with other database extensions (such as MySQL). The preferred form is the first, where the dbhandle parameter is the first parameter to the function.

Return Values

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.

The column names returned by SQLITE_ASSOC and SQLITE_BOTH will be case-folded according to the value of the sqlite.assoc_case configuration option.

Changelog

Version Description
5.1.0 Added the error_msg parameter

Examples

Example #1 Procedural example

<?php
$dbhandle 
sqlite_open('mysqlitedb');
$query sqlite_exec($dbhandle"UPDATE users SET email='jDoe@example.com' WHERE username='jDoe'"$error);
if (!
$query) {
    exit(
"Error in query: '$error'");
} else {
    echo 
'Number of rows modified: 'sqlite_changes($dbhandle);
}
?>

Example #2 Object-oriented example

<?php
$dbhandle 
= new SQLiteDatabase('mysqlitedb');
$query $dbhandle->queryExec("UPDATE users SET email='jDoe@example.com' WHERE username='jDoe'"$error);
if (!
