SQLiteDatabase->exec — Executes a result-less query against a given database
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.
The SQLite Database resource; returned from sqlite_open() when used procedurally. This parameter is not required when using the object-oriented method.
The query to be executed.
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: 為相容其它資料庫(例如 MySQL),支援另兩種替代的語法。推薦用第一種,dbhandle 參數作為函式的第一個參數。
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().
由 SQLITE_ASSOC 和 SQLITE_BOTH 回傳的欄名會根據 sqlite.assoc_case 設定選項的值來決定大小寫。

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'", $error);
if (!$query) {
exit("Error in query: '$error'");
} else {
echo 'Number of rows modified: ', $dbhandle->changes();
}
?>
