Comparing Recordsets in a Database

Click here for a larger image.

Environment: VC6 SP4, NT4 SP6, ADO 2.5

Everyone knows this. You have a complex table structure in the database, and then you have to customize the software work and change this data. How do you compare and verify the results of the new version with the old? With this little tool, you can define a set of queries and its parameters (referenced in the query like $$parametername$$) and dump these results to a file. Two of these files can be compared with the program "WinDiff."

Tip: Look at the macros and the functions in the CAdoUti class.


I used the CGridCtrl class from Chris Maunder, just because I thought it's the best. Thanks, Chris!!! (I have modified the grid to use it as a property sheet.)

    We wrote some ASP pages that simply queried the two sets of data and produced web pages from the results of the comparison. It was quick to do and easy to see differences. Links were added to drill into the differences to better see why there were differences.

    Now, whenever we make such changes we run everything through the ASP pages.
