Update query

P: 38
Hi All,
I have an Update query that updates bunch of fields in tableA from another tableB. For one of the fields (a Date field) in tableA I woud like it to be updated only with a non null value, meaning if the new value from tableB is null, do not update. I tried to use under 'Update to' the following expression:
Expand|Select|Wrap|Line Numbers
  1. IIF(tableB.date1 Is Not Null, tableB.date1) 
but it didn't work. Any ideas?

Thanks

Disregard, I figured it out:

Expand|Select|Wrap|Line Numbers
  1. IIF(tableB.date1 Is Not Null, tableB.date1, tableA.oldDate)
