   Do you have any indexes on this table with NOT NULL? Count(*) will use index if there is a not-null index or a bitmapped index (nulls are incorporated in the bitmapped index).

Subject: Counting number of rows

Is there a quick way to count number of rows in a table? Don't want to do select count(*) from..... on a table (such as GL_BALANCES) with more than 250 million rows.
