Connie-
Please explain what you mean by "combine them." I see no IIf statements in your
SQL.

Subject: [MS_AccessPros] Can these queries be put into one query?
Hi all!
I have two queries which in the next step are joined in a union query with other
similar queries. These two are from the same tables and joins but one has "10 As
StatusID" and the other has "8 As StatusID". The only way I can think of to
combine them is to use an Iff statement in the statusID column which I fear will
result in "cannot open more databases" and a decrease in speed. Would it be best
to combine them using the Iff statement or leave them as is or ....? I'd like to
speed up the process and decrease the potential for a "cannot open any more
databases" error.
They are both below.
Thanks!
Connie
SELECT SalesBuyers.ContactID, 10 AS StatusID, Sales.ListID, Sales.SoldDate
FROM (Listings INNER JOIN Sales ON Listings.ListID = Sales.ListID) INNER JOIN
SalesBuyers ON Sales.SalesID = SalesBuyers.SaleID
WHERE (((Sales.SoldDate) Is Not Null) AND ((Sales.BuyerAgencyID)<>1 Or
(Sales.BuyerAgencyID) Is Null));
SELECT SalesBuyers.ContactID, 8 AS StatusID, Sales.ListID
FROM (Listings INNER JOIN Sales ON Listings.ListID = Sales.ListID) INNER JOIN
SalesBuyers ON Sales.SalesID = SalesBuyers.SaleID
WHERE (((Sales.BuyerAgencyID)=1) AND ((Sales.SoldDate) Is Not Null)) OR
(((Sales.SoldDate) Is Not Null) AND ((Listings.ListingAgency)=1));
