I suspect you are correct.

I've seen something like that before. I used to work in a software house where Uniface was the development tool of choice. It was diabolical, but excellent for "database agnostic" applications as it used the best of each database. Anyway, before a "table" could be used, it had to be "opened". The query there was "select * from schema.table" which was parsed only, but never executed. If the parse failed, then the table probably didn't exists and the application would report a problem. I suspect your queries above are something similar? Cheers, Norm.Received on Wed May 02 2012 - 06:37:05 CDT
