PHP5中文手册·Executes a result-less query against a given database -- 追寻梦想＞编程乐园＞PHP 编程

说明

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

bool sqlite_exec ( string $query , resource $dbhandle )

Object oriented style (method):

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).

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.
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: 为兼容其它数据库（例如 MySQL），支持另两种替代的语法。推荐用第一种，dbhandle 参数作为函数的第一个参数。

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 返回的列名会根据 sqlite.assoc_case 配置选项的值来决定大小写。
