Hi,
As you can see below I have a query which includes records from the
reservation table, but I want to show only those records which their arrival
date ARRIVAL of the RESERVATIONS table is equal to the value of RUNDAY in
the HOUSEKEEPING DATA Query.



SELECT ROOMS.ROOMS, [HOUSEKEEPING DATA].HOTELAPT, [HOUSEKEEPING
DATA].PERSONS, [HOUSEKEEPING DATA].RESNAME, [HOUSEKEEPING DATA].ARRIVAL,
[HOUSEKEEPING DATA].DEPARTURE, [HOUSEKEEPING DATA].TOWELS, [HOUSEKEEPING
DATA].[TOWELS NEXT], [HOUSEKEEPING DATA].LINEN, [HOUSEKEEPING DATA].[LINEN
NEXT], [HOUSEKEEPING DATA].RUNDAY, RESERVATIONS.PERSONS,
RESERVATIONS.RESNAME, RESERVATIONS.COMPANY, RESERVATIONS.ARRIVAL
FROM (ROOMS LEFT JOIN [HOUSEKEEPING DATA] ON ROOMS.ROOMS = [HOUSEKEEPING
DATA].ROOMNO) LEFT JOIN RESERVATIONS ON ROOMS.ROOMS = RESERVATIONS.ROOMNO
GROUP BY ROOMS.ROOMS, [HOUSEKEEPING DATA].HOTELAPT, [HOUSEKEEPING
DATA].PERSONS, [HOUSEKEEPING DATA].RESNAME, [HOUSEKEEPING DATA].ARRIVAL,
[HOUSEKEEPING DATA].DEPARTURE, [HOUSEKEEPING DATA].TOWELS, [HOUSEKEEPING
DATA].[TOWELS NEXT], [HOUSEKEEPING DATA].LINEN, [HOUSEKEEPING DATA].[LINEN
NEXT], [HOUSEKEEPING DATA].RUNDAY, [HOUSEKEEPING DATA].ROOMNO,
RESERVATIONS.PERSONS, RESERVATIONS.RESNAME, RESERVATIONS.COMPANY,
RESERVATIONS.ARRIVAL;

Thanks

Just add a where clause before the group by.

SELECT ROOMS.ROOMS
, [HOUSEKEEPING DATA].HOTELAPT
, [HOUSEKEEPING DATA].PERSONS
, [HOUSEKEEPING DATA].RESNAME
, [HOUSEKEEPING DATA].ARRIVAL
, [HOUSEKEEPING DATA].DEPARTURE
, [HOUSEKEEPING DATA].TOWELS
, [HOUSEKEEPING DATA].[TOWELS NEXT]
, [HOUSEKEEPING DATA].LINEN
, [HOUSEKEEPING DATA].[LINEN NEXT]
, [HOUSEKEEPING DATA].RUNDAY
, RESERVATIONS.PERSONS
, RESERVATIONS.RESNAME
, RESERVATIONS.COMPANY
, RESERVATIONS.ARRIVAL
FROM (ROOMS LEFT JOIN [HOUSEKEEPING DATA]
ON ROOMS.ROOMS = [HOUSEKEEPING DATA].ROOMNO)
LEFT JOIN RESERVATIONS ON ROOMS.ROOMS = RESERVATIONS.ROOMNO

WHERE Reservations.Arrival = [HouseKeeping Data].RunDay

GROUP BY ROOMS.ROOMS
, [HOUSEKEEPING DATA].HOTELAPT
, [HOUSEKEEPING DATA].PERSONS
, [HOUSEKEEPING DATA].RESNAME
, [HOUSEKEEPING DATA].ARRIVAL
, [HOUSEKEEPING DATA].DEPARTURE
, [HOUSEKEEPING DATA].TOWELS
, [HOUSEKEEPING DATA].[TOWELS NEXT]
, [HOUSEKEEPING DATA].LINEN
, [HOUSEKEEPING DATA].[LINEN NEXT]
, [HOUSEKEEPING DATA].RUNDAY
, [HOUSEKEEPING DATA].ROOMNO
, RESERVATIONS.PERSONS
, RESERVATIONS.RESNAME
, RESERVATIONS.COMPANY
, RESERVATIONS.ARRIVAL

By the way you can accomplish the same thing without grouping by including
DISTINCT after SELECT in the query.

SELECT DISTINCT ROOMS.ROOMS
, [HOUSEKEEPING DATA].HOTELAPT
, [HOUSEKEEPING DATA].PERSONS
, [HOUSEKEEPING DATA].RESNAME
, [HOUSEKEEPING DATA].ARRIVAL
, [HOUSEKEEPING DATA].DEPARTURE
, [HOUSEKEEPING DATA].TOWELS
, [HOUSEKEEPING DATA].[TOWELS NEXT]
, [HOUSEKEEPING DATA].LINEN
, [HOUSEKEEPING DATA].[LINEN NEXT]
, [HOUSEKEEPING DATA].RUNDAY
, RESERVATIONS.PERSONS
, RESERVATIONS.RESNAME
, RESERVATIONS.COMPANY
, RESERVATIONS.ARRIVAL
FROM (ROOMS LEFT JOIN [HOUSEKEEPING DATA]
ON ROOMS.ROOMS = [HOUSEKEEPING DATA].ROOMNO)
LEFT JOIN RESERVATIONS ON ROOMS.ROOMS = RESERVATIONS.ROOMNO

WHERE Reservations.Arrival = [HouseKeeping Data].RunDay

Hi John,
Tried it but it returned with no results since there is a
record which has the same value in the Arrival field as the runday field.

Hi John,
I worked it out, I made a separate query filtering out
todays arrivals called it qryarrivals and added it to the query housekeeping
adjusted the union and it worked. Here is the SQL to it:


SELECT ROOMS.ROOMS, [HOUSEKEEPING DATA].HOTELAPT, [HOUSEKEEPING
DATA].PERSONS, [HOUSEKEEPING DATA].RESNAME, [HOUSEKEEPING DATA].ARRIVAL,
[HOUSEKEEPING DATA].DEPARTURE, [HOUSEKEEPING DATA].TOWELS, [HOUSEKEEPING
DATA].[TOWELS NEXT], [HOUSEKEEPING DATA].LINEN, [HOUSEKEEPING DATA].[LINEN
NEXT], [HOUSEKEEPING DATA].RUNDAY, qryARRIVALS.ROOMNO, qryARRIVALS.COMPANY,
qryARRIVALS.ARRIVAL, qryARRIVALS.PERSONS, qryARRIVALS.RESNAME
FROM qryARRIVALS RIGHT JOIN (ROOMS LEFT JOIN [HOUSEKEEPING DATA] ON
ROOMS.ROOMS = [HOUSEKEEPING DATA].ROOMNO) ON qryARRIVALS.ROOMNO =
ROOMS.ROOMS
GROUP BY ROOMS.ROOMS, [HOUSEKEEPING DATA].HOTELAPT, [HOUSEKEEPING
DATA].PERSONS, [HOUSEKEEPING DATA].RESNAME, [HOUSEKEEPING DATA].ARRIVAL,
[HOUSEKEEPING DATA].DEPARTURE, [HOUSEKEEPING DATA].TOWELS, [HOUSEKEEPING
DATA].[TOWELS NEXT], [HOUSEKEEPING DATA].LINEN, [HOUSEKEEPING DATA].[LINEN
NEXT], [HOUSEKEEPING DATA].RUNDAY, [HOUSEKEEPING DATA].ROOMNO,
qryARRIVALS.ROOMNO, qryARRIVALS.COMPANY, qryARRIVALS.ARRIVAL,
qryARRIVALS.PERSONS, qryARRIVALS.RESNAME;

Thanks.
