Comments - Recursive Common Table Expressions Overview

1 month, 4 weeks ago Jan Steinman

It took a long time to find out that aggregate functions cannot be used in the recursive portion of a CTE.

I'm trying to do roll-ups of a hierarchical accounting system, without limiting the number of levels that can be traversed. I thought I had it figured out, but kept getting "Query Failed. Restrictions imposed on recursive definitions are violated for table 'CTE2'. Error code 4008."

Is there a list of the "restrictions" that are "imposed" on recursive CTEs?

It seems to me that recursively getting a SUM of account balances that have the same super-account would be a relatively common thing to do!

Try setting `standard_compliant_cte` to OFF.
