    FROM sys.dm_db_partition_stats

DECLARE @Edition sql_variant
SELECT  @Edition =DATABASEPROPERTYEX ( DB_Name() , 'Edition' )

SELECT    (CASE
    WHEN @SizeInBytes/1073741824.0 < 1 THEN
(CASE @Edition WHEN 'Web' THEN 9.99 ELSE 99.99 END)
    WHEN @SizeInBytes/1073741824.0 < 5 THEN
(CASE @Edition WHEN 'Web' THEN 49.95 ELSE 99.99 END)
    WHEN @SizeInBytes/1073741824.0 < 10 THEN 99.99 
    WHEN @SizeInBytes/1073741824.0 < 20 THEN 199.98
    WHEN @SizeInBytes/1073741824.0 < 30 THEN 299.97            
    WHEN @SizeInBytes/1073741824.0 < 40 THEN 399.96

    WHEN @SizeInBytes/1073741824.0 < 50 THEN 499.95            
         END)  / @SizeInBytes SELECT idx.name,
SUM(reserved_page_count) * 8192 'bytes',
      (SUM(reserved_page_count) * 8192) * @CostPerByte 'cost'
FROM sys.dm_db_partition_stats AS ps
    INNER JOIN sys.indexes AS idx ON
