The entries are not NULL. What makes you think they are? Are you sure they're not just empty ('')?

Your syntax is fine - and very simple. Try inverting the query

select * from tableA

where col5 is not NULL

and see whether the 'blanks' are returned.

I think that your understanding is wrong this time - NULLs are fine in FK constraints - at least in SQL Server (BOL confirms).

When the user clicks save, why not run an UPDATE query instead?

UPDATE article SET Flag = 3 where ArticleID = [ArticleID from form]

Try

select convert(char(12),dateadd(s, 5400, 0),114)

for your conversion question.

Your second question - just use

IF NOT EXISTS (select procedure entry here) CREATE PROCEDURE

For defaults, the SQL Server equivalent of now() is GetDate() and the equivalent of date() is (convert(datetime,floor(convert(float,getdate()))))

Here's another way that should run quicker.

declare @then datetime

set @then = DateAdd(Day, -7, getdate())

select open_dt

from dbo.tbl_metrics_grca_fl

where open_dt >= @then

When you create a SQL statement like this in VB it becomes (as you've noticed) very difficult to work out whether it's correct. I suggest you do something like the...

As far as I can think, this is best left to the application.  There is no standard way of enforcing this - nor can I envisage one.
