query for 'null' in a date column-how?

It depends on the ANSI compliance settings on the server. By default SQL Server allows ' = NULL', but this is not
ANSI compliant and will break if this setting changes on the server.
(Maybe it's settable per connection, I don't remember offhand)

The preferred way is to use the keywords IS NULL or IS NOT NULL.

I ran a query on a table I have where dates can me null (inventory table) and the select * from thetable where thedate = null works fine
with me. You must use the column name exactly as it is listed on your structure, specially if your server is case sensitive.

Good luck.

I know I am missing something basic, here.
I have a date field in a table. The field is 'allowed Nulls'. When a certain thing happens in the program, the date is filled in.
At various times, I need to do a query to find all the rows that have no dates entered.

What do I use in my where clause? SQL server does not like 'where date = null.'

Thanks,
Judith
