Re: find column name that has under score (_)

Try just using the string function "position". You'll need to check the
documentation or wait for others to determine which specific system views
you will need to obtain the column name (if you do not already know that
part).

position(substring in string) int

Non-Zero (or maybe >= 0) indicates the substring was found - though I would
test with some known sample data just to make sure before running it on the
column names.
