DAO OpenRecordset and NULL results?

[RobinDiederen]

Using the code hereunder, I query my database (from MS Access VBA code). Some of my queries give empty results, which isn't like by my program.

For example:

R5SQLC1 = "SELECT COUNT(*) FROM Planning AS D1, Planning AS D2 WHERE D1.werknemer=" & TheWorker & " AND D2.werknemer=" & TheWorker & " AND (D1.AanvangsTijd <= D1.Stoptijd) AND (DateDiff('d', D1, D2) = 1) AND (((D2.AanvangsTijd + 24) - D1.Stoptijd) < 44) AND D1.Datum < D2.Datum"
Debug.Print R5SQLC1
Set C1 = Db.OpenRecordset(R5SQLC1, dbOpenDynaset)
 

This gives as an error:

Run-time error '3601':
Too few parameters, expected 2

For as far as I can tell, this has to do with empty results. As these queries sometimes give empty results, I really need to do something about this. Thing is.. what, and how?

Thanks in advance!

I think, You must the following syntax:

SELECT COUNT(Fieldname) FROM Planning AS [D1], Planning AS [D2] WHERE D1.werknemer=" & TheWorker & ", D2.werknemer=" & TheWorker & "... etc
 

Try that.

Try that.

Use the following:

count the selected recordset.
n= C1.recordcount
if n>0 then
.... do what you want
else
exit sub
end if

You will not see the error message.

Good Luck.

Thanks all. Doing it the dirty way (testing on the size of the recordset) is what does the trick..

Thanks!
