mssql_select_db

(PHP 4, PHP 5, PECL odbtp:1.1.1-1.1.4)

mssql_select_db — Select 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

如果成功则返回 TRUE，失败则返回 FALSE。

范例

Example#1 mssql_select_db() example

<?php
$conn = mssql_connect('MYSQLSERVER', 'sa', 'password');
mssql_select_db('[my data-base]', $conn);
?>
