    Validity period as key attribute possible?

    Hello Namliam, On using Startdate and Enddate: I've decided to go for the only startdate variety because it reduces the risk of error during a query. I shudder to think what would happen if there are missing periods inside the reporting period, on which my query depends. For me, the...

    Exporting Access to Excel Help Please

    Well, there's not much to change in the transferspreadsheet method, so in your place I would sort the table according to office number, copy all data and write the code to sort them out afterwards. I don't see any possibility for shortcuts.

    Validity period as key attribute possible?

    Thank you, The_Doc_Man, for a very good response. Now that you've said it, naturally a three-column keys has a high overhead, especially for indexing I guess. I always thought artificial keys only create additional, useless data but now I know better.

    What a badly formulated question from my side. Thank you namliam, it's not that I didn't know how to set a more than one attributes to be key. I only thought I wouldn't need to any write validation code if I could somehow define the time range & EmployeeID to be PK together.

    Access To Excel Stopped working

    I had a similar problem transferring spreadsheet but my error message at that time was "Error 3048, no more databases could be started" and I know that's because I have too many queries running. Try changing the data types and please let me know how it goes, maybe it's just an overload problem.

    Access To Excel Stopped working

    Since I can't see your queries, I suggest that you check those queries again to see if they return any error. Maybe you could run them one by one and can then pinpoint which exact query/ies cause the problem.

    multiple checkbox arguments in query

    What about evaluating each checkbox like this (just a pseudo code) The idea is to divide the sql string into three parts and manipulate each part accordingly. For the where clause part you can iterate all the check boxes and prolongs the clause with "AND column1 = true" for each checkbox...
