------------------------------------
Assignee: Mihai Budiu
> FamilyOperandTypeChecker with a Predicate describing optional arguments does
> not reject mistyped expressions
> ------------------------------------------------------------------------------------------------------------
>
> Key: CALCITE-6984
> URL: https://issues.apache.org/jira/browse/CALCITE-6984
> Project: Calcite
> Issue Type: Bug
> Components: core
> Affects Versions: 1.39.0
> Reporter: Mihai Budiu
> Assignee: Mihai Budiu
> Priority: Minor
>
> [CALCITE-6976] is a symptom of a deeper problem: the family operand type
> checker using a predicate for specifying optional arguments will accept
> mistyped expressions if their number of arguments does not match the maximum
> number of arguments.
> This affects at least 20 functions from SqlLibraryOperators.
> A partial solution is to use the .or type checker when possible.
