mssql_select_db — Select MS SQL database
$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.
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.
Returns TRUE on success or FALSE on failure.
Example #1 mssql_select_db() example
<?php
// Create a link to MSSQL
$link = mssql_connect('KALLESPC\SQLEXPRESS', 'sa', 'phpfi');
// Select the database 'php'
mssql_select_db('php', $link);
?>
Example #2 Escaping the database name with square brackets
<?php
// Create a link to MSSQL
$link = mssql_connect('KALLESPC\SQLEXPRESS', 'sa', 'phpfi');
// Select the database 'my.database-name'
mssql_select_db('[my.database-name]', $link);
?>
