Hi, I want to surf an ItemExpr tree (actually a set of them: check constraints) and find all the ITM_BASECOLUMN nodes in them. Ideally, I'd like to obtain a ValueIdSet of these nodes, with duplicates removed. By duplicates, I mean, two nodes really are the same column. Example: check b > 0 and b < 100. I'd like 'b' to occur just once.
I'd guess this is a problem someone has already solved. Is there a method that will do this? Thanks, Dave
