Sorry, I know that this is an 'horse already bolted' solution.
However, wherever possible (and I know that this is usually due to inheriting responsibility of 'legacy' databases); whenever I create a database, I ensure that data is stored in the case format that I meed it to be OR update the data to be that format (this is generally only a very small sub-set of the data anyway).
I'd much rather solve the underlying issue once, as, if this data was exported elsewhere - would it not take this issue with it?

Never argue with an idiot, he'll bring you down to his level - then beat you with experience.
