(PHP 5, PECL sqlite >= 1.0.3)
sqlite_exec -- SQLiteDatabase->exec — Executes a result-less query against a given database
Object oriented style (method):
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).
WarningSQLite 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.
Data inside the query should be properly escaped.
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: 为兼容其他数据库扩展(比如 MySQL)，支持两种可替代的语法。推荐第一种格式，函数的第一个参数是dbhandle。
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 与 SQLITE_BOTH 返回的列名会依照 sqlite.assoc_case 配置选项的值决定大小写。
| 版本 | 说明 |
|---|---|
| 5.1.0 | Added the error_msg parameter |
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();
}
?>
