The fact that you need this done is indicitive of a database design probem. Are you oversimplifying your problem?

I suppose it could be done using a stored procedure which figures out the maximum number of characters there could be. Then some weird combination of LEFT() and GROUP BY/COUNT(*) to find the leftmost strings that are all counted the most number of times. The highest one of those tells you the number of characters that were found to be identical.
