| Hi all. Have a query and i'm really not sure how to approah it.OK, I have two tables. In the first table (ABSENCE) i have three fields FROMDATE, UNTILDATE and TOTAL HOURS.These field state the start and end date of an absence. I have a second table (WORKPATTERN) in this table are stored etails of an individual workpattern.It contains two fields DATE and HOURS. It stores each individual date in a workpattern and how many hours are worked on that day.Obviously there are days missed in the work pattern (I.E. saturday, sunday and bank holidays etc).What i need to do is work out the TOTALHOURS for a particlar absence. This means i need scan the range of FROMDATE to UNTILDATE.If there is a matching date in the WORKPATTNT table i need to add the HOURS for that record to running total.Not sure if ive explained it all that well. But any advice would be smashing. Thanks people. |

It will be very much clearer if you could also post the table structure, some sample data and the result that you want.

Begin with this and see if it is getting any clearerSELECT a.*, (SELECT SUM(wp.Hours) FROM WorkPattern wp WHERE wp.Date BETWEEN a.FROMDATE AND a.UntilDate)FROM Absence a Peter LarssonHelsingborg, Sweden |
