mssql_select_db

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

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

成功时返回 TRUE，或者在失败时返回 FALSE.
