For a particular Form I need the results of a CrossTab query. That Ctab query will have ItemIDs as its columns and Day's total info as its rows.
Since I've never used CTab queries I wanted to know how reliable they will be in my Form or will it "blow" up if an Item all of a sudden has no info for a day when before it always had info....
EXAMPLE - My Crosstab query is based on this query's code.
SELECT qry_InfoDetails_EndofDay.BusDay, qry_InfoDetails_EndofDay.MachPollPositionID, qry_InfoDetails_EndofDay.AmtIn, qry_InfoDetails_EndofDay.EndofDay
FROM qry_InfoDetailsLastPullDate INNER JOIN qry_InfoDetails_EndofDay ON qry_InfoDetailsLastPullDate.MachPollPositionID = qry_InfoDetails_EndofDay.MachPollPositionID
GROUP BY qry_InfoDetails_EndofDay.BusDay, qry_InfoDetails_EndofDay.MachPollPositionID, qry_InfoDetails_EndofDay.AmtIn, qry_InfoDetails_EndofDay.EndofDay
ORDER BY qry_InfoDetails_EndofDay.BusDay, qry_InfoDetails_EndofDay.MachPollPositionID;
THEN...My cross tab query will pull info as:
TRANSFORM Sum(qry_LVLInfoDetailEODSinceLastPull.AmtIn) AS SumOfAmtIn
SELECT qry_LVLInfoDetailEODSinceLastPull.BusDay, Sum(qry_LVLInfoDetailEODSinceLastPull.AmtIn) AS [Total Of AmtIn]
GROUP BY qry_LVLInfoDetailEODSinceLastPull.BusDay
Since my MachPollPositionID's always will be numbers 1 to 10 but if there is NO EndofDay = True records will it bomb out or is there a way in the first query I can have it put a zero (0) number in every poll position for data=today that would prevent a null query.
