------------------------------------
Summary: 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
[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.
