Select MS SQL database

Warning

This function was REMOVED in PHP 7.0.0.

Alternatives to this function include:

Description

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.

Parameters

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.

Return Values

Returns TRUE on success or FALSE on failure.

Examples

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);
?>
