> Key: CALCITE-7301
> URL: https://issues.apache.org/jira/browse/CALCITE-7301
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.41.0
> Reporter: Dmitry Sysolyatin
> Assignee: Dmitry Sysolyatin
> Priority: Major
> Labels: pull-request-available
>
> Many issues like [CALCITE-5439], [CALCITE-4406], [CALCITE-6178], and
> [CALCITE-7339] have the same problem. If SqlShuttle or any other mechanism
> creates a copy of a SqlCall with different operands, and the operator does
> not implement createCall, then it fails to unparse/validate the SqlNode
> This task adds a common test case that runs on existing parsing tests and
> checks that unparsing after a deep copy works correctly. It also fixes the
> SqlOperators for which common test was failing
