[dba-SQLServer] Optimizing nVLDB databases

When I did this, it didn't give an error but it returned 0 rows.  What is
indid?

Repeat from my posting in this list pm Sat 21 Aug 04. 

There is another way to determine the total row count in a table. You can 
use the sysindexes system table for this purpose. There is ROWS column in 
the sysindexes table. This column contains the total row count for each 
table in your database. So, you can use the following select statement 
instead of above one:

SELECT rows FROM sysindexes WHERE id = OBJECT_ID('table_name') AND indid < 
2
