mssql_select_db — Select MS SQL database

Описание

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.

Список параметров

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.

Возвращаемые значения

Возвращает TRUE в случае успешного завершения или FALSE в случае возникновения ошибки.

Примеры

Пример #1 mssql_select_db() example

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

Use of square brackets to enclose the database name is also necessary if the name contains a dot: '.' 

e.g.

mssql_select_db('Company.ERP');
 
Produces the error:
Warning: mssql_select_db(): Sybase:  Server message:  Could not locate entry in sysdatabases for database 'Company'. No entry found with that name. Make sure that the name is entered correctly. (severity 16, procedure N/A) in

mssql_select_db('[Company.ERP]');
 
Will select successfully

I have noted that mssql_select_db fails if the database name contains a dash or hyphen. for example a database named foo-bar will fail and the error that is returned indicates that the name was interpreted as only 'foo'
