How to check the Largest Object of a Database

The following script is used to get the largest database object

 

SELECT

    t.NAME AS TableName

    ,i.name as indexName

    ,sum(p.rows) as RowCounts

    ,sum(a.total_pages) as TotalPages

    ,sum(a.used_pages) as UsedPages

    ,sum(a.data_pages) as DataPages

    ,(sum(a.total_pages) * 8) / 1024 as TotalSpaceMB

    ,(sum(a.used_pages) * 8) / 1024 as UsedSpaceMB

    ,(sum(a.data_pages) * 8) / 1024 as DataSpaceMB

FROM sys.tables t

INNER JOIN sys.indexes i ON t.OBJECT_ID = i.object_id

INNER JOIN sys.partitions p ON i.object_id = p.OBJECT_ID AND i.index_id = p.index_id

INNER JOIN sys.allocation_units a ON p.partition_id = a.container_id

WHERE t.NAME NOT LIKE 'dt%'

            AND i.OBJECT_ID > 255

            AND i.index_id <= 1

GROUP BY

    t.NAME, i.object_id, i.index_id, i.name

ORDER BY SUM(a.total_pages) DESC
