Question : select query

Hi, quick question.

I'm making a select query on a table.  1 of the columns is date.  I want to do 2 queries, 1 which shows all the records where the field date has a date and the other where it shows all the records which don't have a date.

For the "DATE" in critera of query design I'm typing ">0" and this works fine.

For the "No Date" Im typing "<0" this brings up no records?  

Any ideas please?

Answer : select query

select *
from Tablename
where [datefield] is not null


select *
from Tablename
where [datefield] is null
