Subject:Parse Tree Question
View as plain text  

I am accessing the parse tree for a select query from within a storage 
engine, and can move along the item list to get the fields and the 
values. However, I cannot work out how to determine the predicate 
operator, so I can't see if it was a = or a !=. I get items of type 
FIELD_ITEM and FIELD_VARIANCE_ITEM. How can I see or test for all the 
possible operators (=, !=, like etc).

I have a feeling I will sheepishly say thanks when someone points out 
the obvious, but I need the blinkers removing first.

Many thanks,
