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

说明

bool sqlite_exec ( resource dbhandle, string query )

bool sqlite_exec ( string query, resource dbhandle )

Object oriented style (method):

class SQLiteDatabase {

bool exec ( string query )

}

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

警告

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

query

The query to be executed.

dbhandle

The SQLite Database resource; returned from sqlite_open () when used procedurally. This parameter is not required when using the object-oriented method.

注: 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.

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().

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.

例子 1. Procedural example

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

例子 2. Object-oriented example

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