Determine SQL Server Database Size

Question

SQL Server 2005/2008 Express edition has the limitation of 4 GB per database. As far as I known the database engine considers data only, thus excluding log files, unused spa

Answer 1

I always liked going after it directly:

SELECT 
    DB_NAME( dbid ) AS DatabaseName, 
    CAST( ( SUM( size ) * 8 ) / ( 1024.0 * 1024.0 ) AS decimal( 10, 2 ) ) AS DbSizeGb 
FROM 
    sys.sysaltfiles 
GROUP BY 
    DB_NAME( dbid )
