Select MS SQL database


mssql_select_db

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

mssql_select_dbSelect MS SQL database

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);
?>
