I'm trying to pattern match something using LIKE. The below isn't my actual problem, but say I want one or more repetitions of a group of characters, for instance digits or comma (may be different groups of characters).
Matching a single digit or comma would be '[0-9,]', but what if I want to match against one or more repetitions?
I've tried '[0-9,]' and '[0-9,]*', but * matches a single wildcard. Effectively my question is how do I repeat a sequence in LIKE?
