We are running a DB performance monitor. It shows extents allocated >200. We run DBCC SHOWCONTIG on a table and shows:
Scan density is 20%
Logical Scan Fragmemtation is 40%
Extent Scan Fragmentation is 77%

others show:

Scan density is 66%
Logical Scan Fragmemtation is 0%
Extent Scan Fragmentation is 66%

Is there a problem here and if so how do I fix? We have run DBCC REINDEX on the tables but it did not correct the numbers.

thanks,
Adam Bean

You might want to run a DBCC UPDATEUSAGE to ensure you're still receiving the correct numbers.

Does this table have a clustered index? Because heaps (tables without a clustered index) essentially can't be defragmented: the only way to approximate it is to create another table and copy all records into the new table.

Great, thanks, there are no clustered indexes on the table.
