Rows in a table

[karthik]

I have an interesting problem - I get a different number of rows for
the number of rows in a table when I double click the table name in EM
and when I run a select count(*) from <tablename> in QA.

Can somebody tell me why this is happening? The numbers are off only by
a few hundreds though.

I rarely use EM, and even more rarely double-click tables in it, but
I doubt that the double-click performs a SELECT COUNT(*) - this could
take a long time on a hundred-million row table! I would guess that
EM reads sysindexes.rows which is an estimate which is not necessarily
update to date. You can bring it update with DBCC UPDATESUAGE.
