Re: Select Cast Error

This where clause is just returning a number but not comparing it to
anything.  Normally it would be something like WHERE test.test  =
max(substring(test.test from 11 for 2)).  That is the reason for the
error message you are seeing.

I don't quite get how you are expecting to return 4 from 0004 instead of
3 from 0003 based on the statement above.
