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

說明

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).

警示

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.

參數

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.

注: 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 參數作為函數的第一個參數。

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().

由 SQLITE_ASSOC 和 SQLITE_BOTH 返回的列名會根據 sqlite.assoc_case 配置選項的值來決定大小寫。

更新日誌

版本說明
5.1.0 Added the error_msg parameter

範例

例子 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);
}
?>

例子 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();
}
?>
