# sqlite_exec

(PHP 5)

sqlite_exec

(no version information, might be only in CVS)

SQLiteDatabase->exec -- Executes a result-less query against a given database

## Beschreibung

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

Object oriented style (method):

class SQLiteDatabase {
bool queryExec ( string query [, string &error_msg] )
}

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

Warnung
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.

## Parameter Liste

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.

> Anmerkung: 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.

## Rückgabewerte

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

## Beispiele

Beispiel 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); } ?>`

Beispiel 2. Object-oriented example

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