Can the SUM keyword in SELECT be generalized to strings? A tipical use for the SUM keyword is:
SELECT column1, SUM(column2) FROM table GROUP BY column1 This works only if column2 contains numbers (and SUM is the mathematical sum). What about obtain the same behaviour, when column2 contains strings (and SUM is string concatenation)? Anyone help me please?
