we are actually looking for a tool that can be used to compare data in SQL tables. The tool should have features wherein we can select the fields to be compared. Please get back in case any of you are aware of such a tool
no tool that I know of, but it shouldn't be that hard to write your own in either spufi or qmf. I'm gonna assume that you will probably need to use outer joins (or several unions for 'not exists' conditions) to match keys and/or find out which rows are not present. Something like this shouldn't take longer than a half hour to write.
Or you could simply extract the data to a flat file and run a compare against it.
