Modified DB Query (MSSQL) : Object Info

Here is a slightly altered version of the Object Info (MSSQL) DB Query. It retrieves addition information about tables (row number, reserved/data/index/unused size).

Code:

-- WARNING: This query works only for objects in the current database

IF :DB_NAME IS NOT NULL
IF :DB_NAME != DB_NAME()
BEGIN
SELECT 'WARNING: This query works only for objects in the current database'
RETURN
END

or @@version like '%SQL Server 2008%'
or @@version like '%SQL Server 2012%'
