# mssql_select_db

(PHP 3, PHP 4 , PHP 5)

mssql_select_db -- Select MS SQL database

## Description

bool mssql_select_db ( string database_name [, resource link_identifier])

成功回傳`TRUE`失敗回傳`FALSE`。

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

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

In order to select a database containing a space or a hyphen ("-") you need to enclose the database name in brackets, like is shown in the example below:

示範 1.mssql_select_db() example
