This week's book giveaway is in the General Computing forum. We're giving away four copies of Arduino in Action and have Martin Evans, Joshua Noble, and Jordan Hochenbaum on-line! See this thread for details.
I built an application using a CachedRowSet. (For other newbies it is used as a disconnected Result Set.) My users like it because they can bring data into it and do data manipulations on different rows within the set and then when everything is to their liking all the data can be sent back to the database with all of the changes for everything. Also, my users can add new data rows to this set.
My problem is that my users want to be able to search fields within the set for specific values but each field can have duplicate values, so, I do not have anything like a primary key except for the row number that I create. So basically my users have to search through the entire set one record at a time to find the record within the set that they would like to change.
Do you have any suggestions on what I can do with this critter, remembering that the fields that they want to search on have duplicate values?
