More pain and sufferring with Tropashko's materialized path...

When I execute this function with a number such as 113755/65536, I get arithmetic overflow. When I convert them to "real", same problem. Everything is fine with smaller numbers, such as you get for the test cases given.

This problem has occurred on a test tree containing only 500 nodes that goes to a depth of 12. I thought I had this materialized path thing cracked, but it seems I haven't! (using MS T-SQL by the way, perhaps there is some other data-type I should be using?).

Any ideas?

         RETURN _at_numer * POWER ( 2, @child ) + 3 - POWER ( 2, @child )     END Received on Mon Sep 15 2003 - 20:06:00 CEST
