Question
I think most people know how to do this via the GUI (right click table, properties), but doing this in T-SQL totally rocks.
Solution
CREATE TABLE #tmpSizeChar ( table_name sysname , row_count int, reserved_size varchar(50), data_size varchar(50), index_size varchar(50), unused_size varchar(50)) CREATE TABLE #tmpSizeInt ( table_name sysname , row_count int, reserved_size_KB int, data_size_KB int, index_size_KB int, unused_size_KB int) SET NOCOUNT ON INSERT #tmpSizeChar EXEC sp_msforeachtable 'sp_spaceused ''?''' INSERT INTO #tmpSizeInt ( table_name, row_count, reserved_size_KB, data_size_KB, index_size_KB, unused_size_KB ) SELECT [table_name], row_count, CAST(SUBSTRING(reserved_size, 0, PATINDEX('% %', reserved_size)) AS int)reserved_size, CAST(SUBSTRING(data_size, 0, PATINDEX('% %', data_size)) AS int)data_size, CAST(SUBSTRING(index_size, 0, PATINDEX('% %', index_size)) AS int)index_size, CAST(SUBSTRING(unused_size, 0, PATINDEX('% %', unused_size)) AS int)unused_size FROM #tmpSizeChar /* DROP TABLE #tmpSizeChar DROP TABLE #tmpSizeInt */ SELECT * FROM #tmpSizeInt ORDER BY reserved_size_KB DESC
OTHER TIPS
sp_spaceused tableName
where tableName is the name of the table you want to know....
Check out this, I know it works in 2005 (Microsoft Documentation):
Here is is for the pubs DB
select *
from pubs.sys.database_files
Returns the size and max_size.
