How to improve this query?

Hello!



I want to count those records in a table, where the field I specified is not
empty. How to make such a query efficient. Is there a different/more
efficient way to achieve that, then select count(1) from mytable where
myfield != NULL? Myfield is a varchar2 field. I'm using Oracle 9.




Thanks


Thomas
