Kathey Marsden updated DERBY-3876:
----------------------------------
Component/s: SQL
> Stack overflow when issuing SELECT statements with *lots* of 'OR' in the
> WHERE clause
> -------------------------------------------------------------------------------------
>
> Key: DERBY-3876
> URL: https://issues.apache.org/jira/browse/DERBY-3876
> Project: Derby
> Issue Type: Improvement
> Components: SQL
> Reporter: Øyvind Harboe
>
> The problem is that e.g. Cayenne uses *long* SQL statements with *lots* of OR
> statements to implement certain operations.
> This causes a stack overflow as evaluation of 'OR' is implemented recursively.
> Could an iterative implementation trivially replace the recursive
> implementation?
