Question : Help with a complex query

I have a table that contains a record for each shift segment an employee works. (During a shift an employee may be assigned various activities of differing time frames so the table records each segment). I need to create a recordset that summarises 3 relevant points from each shift, the shift Start Time, the shift End Time and the start time of the first record with a doing code of "UB". I have shown below the query that finds the Start and End time (using the Min and Max functions). I have also added below it a query that finds the records I need to add (the first record in each shift with a doing code of "UB") but I don't know how to combine the two. Can anyone help me?

The following query will create a recordset that combines multiple records to create one record for each shift with a start and end time.

PARAMETERS [Forms]![frmMainRosterPrep]![Roster Preparation Form].[Form]![LstWeeks] DateTime, [Forms]![frmMainRosterPrep]![Roster Preparation Form].[Form]![SelectedWeek] Long;
SELECT tblSubTimeEntries.Start, Min(tblSubTimeEntries.StartDate) AS Starts, Max(tblSubTimeEntries.EndDate) AS Ends, tblSubTimeEntries.SAPNum, tblSubTimeEntries.ShiftNum
FROM tblSubTimeEntries
GROUP BY tblSubTimeEntries.Start, tblSubTimeEntries.SAPNum, tblSubTimeEntries.ShiftNum, tblSubTimeEntries.StoreIdent, tblSubTimeEntries.Start
HAVING (((tblSubTimeEntries.Start)>=[Forms]![frmMainRosterPrep]![Roster Preparation Form].[Form]![LstWeeks]+(7*[Forms]![frmMainRosterPrep]![Roster Preparation Form].[Form]![SelectedWeek]) And (tblSubTimeEntries.Start)<[Forms]![frmMainRosterPrep]![Roster Preparation Form].[Form]![LstWeeks]+(7*[Forms]![frmMainRosterPrep]![Roster Preparation Form].[Form]![SelectedWeek])+7) AND ((tblSubTimeEntries.StoreIdent)=fThisSite()))
ORDER BY tblSubTimeEntries.Start, Min(tblSubTimeEntries.StartDate), tblSubTimeEntries.SAPNum, tblSubTimeEntries.ShiftNum;

The following query will create a query with the time of the first record with a Doing Code of "UB"
SELECT First(tblSubTimeEntries.StartDate) AS UB1
FROM tblSubTimeEntries
WHERE (((tblSubTimeEntries.DoingCode)="UB") AND ((tblSubTimeEntries.StoreIdent)=fThisSite()))
GROUP BY tblSubTimeEntries.Start, tblSubTimeEntries.SAPNum, tblSubTimeEntries.ShiftNum
HAVING (((tblSubTimeEntries.Start)>=[Forms]![frmMainRosterPrep]![Roster Preparation Form].[Form]![LstWeeks]+(7*[Forms]![frmMainRosterPrep]![Roster Preparation Form].[Form]![SelectedWeek]) And (tblSubTimeEntries.Start)<[Forms]![frmMainRosterPrep]![Roster Preparation Form].[Form]![LstWeeks]+(7*[Forms]![frmMainRosterPrep]![Roster Preparation Form].[Form]![SelectedWeek])+7))
ORDER BY tblSubTimeEntries.Start, First(tblSubTimeEntries.StartDate), tblSubTimeEntries.SAPNum, tblSubTimeEntries.ShiftNum;

Answer : Help with a complex query

Then it looks to me like you should be changing qry2 to include all the group fields in the Select clause.

You can then create a new query which is based on these 2 queries and join them on the
 Start, SAPNum,  and ShiftNum fields.

(qry1 has an extra 'Start' grouping at the end of the Group By which should be deleted)
