大家好,我是Phpstudy的开发者猪哥。

Phpstudy是我个人业余时间开发并维,针对phpstudy 后门事件,在这里做一下澄清,这个事件早在2018年12月案件相关网警就已经在公司进行调查,取证,已证明与phpstudy官网无关,软件是被不法分子二次修改。再上传到其他下载站。大家只要官网下载的就不会有问题。

mssql_select_db

mssql_select_db

(PHP 4, PHP 5, PECL odbtp >= 1.1.1)

mssql_select_dbSelect MS SQL database

说明

bool mssql_select_db ( string $database_name [, resource $link_identifier ] )

mssql_select_db() sets the current active database on the server that's associated with the specified link identifier.

Every subsequent call to mssql_query() will be made on the active database.

参数

database_name

The database name.

To escape the name of a database that contains spaces, hyphens ("-"), or any other exceptional characters, the database name must be enclosed in brackets, as is shown in the example, below. This technique must also be applied when selecting a database name that is also a reserved word (such as primary).

link_identifier

A MS SQL link identifier, returned by mssql_connect() or mssql_pconnect().

If no link identifier is specified, the last opened link is assumed. If no link is open, the function will try to establish a link as if mssql_connect() was called, and use it.

返回值

成功时返回 TRUE, 或者在失败时返回 FALSE.

范例

Example #1 mssql_select_db() example

<?php
// Create a link to MSSQL
$link mssql_connect('KALLESPCSQLEXPRESS''sa''phpfi');

// Select the database 'php'
mssql_select_db('php'$link);
?>

Example #2 Escaping the database name with square brackets

<?php
// Create a link to MSSQL
$link mssql_connect('KALLESPCSQLEXPRESS''sa''phpfi');

// Select the database 'my.database-name'
mssql_select_db('[my.database-name]'$link);
?>
