Posted on 2016-08-03
Last Modified: 2016-08-08
Does anyone have a query that can tell me the size of individual tables within one sql database.
if not size in actual data size, maybe rows?  would rather have size in megabytes though

Try this:

    SCHEMA_NAME(t.schema_id) AS schema_name, AS table_name,
    --p.index_id, ISNULL(MAX(, '<heap>') AS index_name,
    CAST(SUM(au.total_pages) / 128.0 AS decimal(9, 2)) AS size_mb,
    CAST(SUM(au.used_pages) / 128.0 AS decimal(9, 2)) AS used_mb,
    CAST(SUM(au.total_pages) / 128.0 AS decimal(9, 2)) -
    CAST(SUM(au.used_pages) / 128.0 AS decimal(9, 2)) AS unused_mb,
    MAX(FILEGROUP_NAME (au.data_space_id)) AS filegroup_name
FROM sys.allocation_units au
INNER JOIN sys.partitions p ON p.partition_id = au.container_id
INNER JOIN sys.tables t ON t.object_id = p.object_id
LEFT OUTER JOIN sys.indexes i ON i.object_id = t.object_id AND i.index_id = p.index_id
WHERE t.schema_id <> (SELECT schema_id FROM sys.schemas WHERE name = 'sys')
GROUP BY SCHEMA_NAME(t.schema_id), --, p.index_id
--ORDER BY size_mb DESC
    'sys' AS schema_name,
    OBJECT_NAME(p.object_id) AS table_name,
    --1 AS index_id, '<internal>' AS index_name,
    CAST(SUM(p.reserved_page_count) / 128.0 AS decimal(9, 2)) AS size_mb,
    CAST(SUM(p.used_page_count) / 128.0 AS decimal(9, 2)) AS used_mb,
    CAST(SUM(p.reserved_page_count) / 128.0 AS decimal(9, 2)) -
    CAST(SUM(p.used_page_count) / 128.0 AS decimal(9, 2)) AS unused_mb,
    '<n/a>' AS filegroup_name
FROM sys.dm_db_partition_stats p
INNER JOIN sys.internal_tables it ON it.object_id = p.object_id
WHERE it.internal_type IN (202,204,207,211,212,213,214,215,216)
GROUP BY p.object_id

If you are using SQL Server Management Studio (SSMS), instead of running a query (which in my case returned duplicate rows) you can run a standard report.

Right click on the database
Navigate to Reports > Standard Reports > Disk Usage By Table

Note: The database compatibility level must be set to 90 or above for this to work correctly. See
LVL 42

in your SSMS select "tables" and click F7 (object Explorer details)
to see space -records per table,,

" i am almost out of drive space because..:"  
check tables that you can delete or truncate for sure
exec sp_spaceused "yourCandidateTabletoBe deleted"

also check the drive for cleanup where you mdf -ndf -ldf files

(BTW: you may have trans log file issue - > can you post some errors?)
if trans log = if DB can be in the Simple recovery- just set it and shrink..
otherwise - it needs trans log backup to keep size


also you may need to order more space for this DB drive(s)

you can also open the 'Object Explorer Details' in SSMS

Top Level of Object Explorer Details

From the Top-Level, open the Tables folder to get a list of all the tables in your database.

You may need to customise the columns to see the Space Used. This can be done by right clicking on the header row and choosing the columns you wish to display.

Try this
exec  sp_spaceused N'dbo.MyTable'

Open in new window

If you are using SQL Server Management Studio then you can also run a standard report
Right click on the DatabaseReportsStandard Reports > Disk Usage By Table
