I have a large dataset consisting of start- and endtimes of personel shifts. I'd like to make a query that calculates the number of shifts per time period. I used to perform this task in Excel using sumpruduct or array formulas quite easily, but I can't figure out a way to to the same in Access.

One table, three columns: id (autonr) , start time(time/date), end time(time/date) The preferred ouput would be something like this: time periode, nr of shifts ie: 07:00-08:00, 5 08:00;09:00, 8 etc -- Message posted via http://www.accessmonster.com

I do not follow your logic. A shift is only one hour long? Are do you want all start to end time periods broken down into one hour increments and then total that?

First, rename your field. Date is a reserved word, and you should never use reserved words for your own purposes. For a comprehensive list of names to avoid (as well as a link to a free utility to check your application for compliance), check what Allen Browne has at http://www.allenbrowne.com/AppIssueBadWord.html Assuming you rename it to shiftdate, try SELECT shiftdate, Sum(IIf([shiftstart]<=#12/30/1899 12:0:0# And [shiftend]>=#12/30/1899 11:0:0#,1,0)) AS [1100 - 1200], Sum(IIf([shiftstart]<=#12/30/1899 13:0:0# And [shiftend]>=#12/30/1899#,1,0)) AS [1200 - 1300], Sum(IIf([shiftstart]<=#12/30/1899 14:0:0# And [shiftend]>=#12/30/1899 13:0:0#,1,0)) AS [1300 - 1400] FROM Shifts GROUP BY shiftdate Realistically, though, you should be storing both date and time for shiftstart and shiftend. In that case, you'd use SELECT DateValue(shiftstart), Sum(IIf(TimeValue([shiftstart])<=#12/30/1899 12:0:0# And TimeValue([shiftend])>=#12/30/1899 11:0:0#,1,0)) AS [1100 - 1200], Sum(IIf(TimeValue([shiftstart])<=#12/30/1899 13:0:0# And TimeValue([shiftend])>=#12/30/1899#,1,0)) AS [1200 - 1300], Sum(IIf(TimeValue([shiftstart])<=#12/30/1899 14:0:0# And TimeValue([shiftend])>=#12/30/1899 13:0:0#,1,0)) AS [1300 - 1400] FROM Shifts GROUP BY DateValue(shiftstart) -- Doug Steele, Microsoft Access MVP http://I.Am/DougSteele (no private e-mails, please) "bertusavius via AccessMonster.com" <u55174@uwe> wrote in message news:a357d0492d63c@uwe... >I would like to add another dimension to this query: > > > my table table now has an added colulumn DATE: > > id, shiftstart, shiftend, DATE > 1, 10:00, 19:00, 1-1-2010 > 2, 11:00, 20:00, 1-1-2010 > 3, 13:00, 15:00, 2-1-2010 > > Karl Dewey's query result looks like this (without the extra column): > > 1100 - 1200 1200 - 1300 1300 - 1400 > 2 3 3 > > I'd like to archieve a result like this (or similar): > > 1100 - 1200 1200 - 1300 1300 - 1400 > 1-1-2010 2 3 3 > 2-1-2010 0 1 1 > > > Is this possible? > > -- > Message posted via http://www.accessmonster.com >
