SQLite 函数
PHP Manual

sqlite_exec

SQLiteDatabase->exec

(PHP 5, PECL sqlite >= 1.0.3)

sqlite_exec -- SQLiteDatabase->execExecutes a result-less query against a given database

说明

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

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).

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.

参数

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: 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

返回值

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().

SQLITE_ASSOCSQLITE_BOTH 返回的列名会依照 sqlite.assoc_case 配置选项的值决定大小写。

更新日志

版本 说明
5.1.0 Added the error_msg parameter

范例

Example #1 Procedural example

<?php
$dbhandle 
sqlite_open('mysqlitedb');
$query sqlite_exec($dbhandle"UPDATE users SET email='[email protected]' 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 $dbhandle->queryExec("UPDATE users SET email='[email protected]' WHERE username='jDoe'"$error);
if (!
$query) {
    exit(
"Error in query: '$error'");
} else {
    echo 
'Number of rows modified: '$dbhandle->changes();
}
?>
