ThanksĀ SQLMenaceĀ (Denis Gobo) for this great tip on getting min/max/average row sizes (and more) using DBCC SHOWCONTIG.
Don’t forget the “with tableresults”, without it, it will skip the min/max/average recordsize from the results, and present the results as text (not as a row).
Run DBCC SHOWCONTIG with your table name
dbcc showcontig ('TableName') with tableresultsthen look at max min and average record size
This feature works at least from SQL Server 2000 onward, though somewhere after SQL Server 2012 it will be removed.
As of SQL Server 2005 you can useĀ sys.dm_db_index_physical_stats. An example on how to use that isĀ here.
It just made me shiver when finding out an unindexed table with 9 million rows averaging about 300 bytes took 8 minutes to query.
Time to add some indexes, and have someone look at the disk back-end.
