Query : dynamic criteria

P: 48

I have a query containing a numeric column on which a criteria is applied. The criteria-value is contained in a workfield/variable.

So far no problem.

Howver I would like to have the query not filtered at all when the workfield/variable contains null.

I tried several constructions, but can't find a way to let the query return all rows in that null-situation.

How could I do this ?

I tried the following criteria :

iif(isnull(workfield);Like "#";workfield)

without luck

Try Like Nz([workfield], "*") which will substitute the wildcard character (the asterisk, not the hash) if the workfield is null.
