“Enter Parameter Value” Dialogue

Question

I get the "Enter Parameter Value" popup when I run the below (asking for November.MPXN)

UPDATE Master SET [MPXN] = November.MPXN, [Clarification Text] = November.[Clarification Text]
WHERE (EXISTS(SELECT 1  FROM November AS November
    WHERE [November.Case] = [Master.Case]));

I assume it isn't pulling the date for November.MPXN for some reason, I would have though it's pretty obvious that it's in the November table but must be something wrong with the query, can anyone help me please?

Answer 1

Maybe you got an answer already but November is not in the same scope as the Update part of the query. It is nested inside your exists statement. You need a join to bring the November data in with the Master data.

UPDATE Master M
INNER JOIN November N
On N.[November.Case] = M.[Master.Case]
SET [MPXN] = November.MPXN
, [Clarification Text] = November.[Clarification Text]

I bet you were using Exists though because the records in Master and November are not 1 to 1 in which case you'll need to have some way to narrowing it down.
