# mssql_select_db

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

mssql_select_db — Select MS SQL database

### Opis

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.

### Parametry

`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.

### Zwracane wartości

Zwraca `TRUE` w przypadku powodzenia, `FALSE` w przypadku błędu.
