Add
AND NOT EXISTS
(SELECT *
FROM Availability A2
WHERE A.AvailRoomID = A2.AvailRoomId
AND A2.AvailDate between #12/09/2005# AND #12/13/2005#
AND A2.AvailDayShow = 0)
If this does not work out, please post:
o CREATE TABLE statements for your tables. Don't forget the keys.
o INSERT statements with sample data.
o The desired result given the sample.
And of course, if you post to this group, you will get syntax for SQL
Server, which may or may not work on Access.
