[jira] [Created] (CALCITE-4295) The minMin function of CompositeOperandTypeChecker should returns the minimum of lower bound of all SqlOperandCountRange

Zhenghua Gao created CALCITE-4295:
-------------------------------------

             Summary: The minMin function of CompositeOperandTypeChecker should returns the minimum of lower bound of all SqlOperandCountRange
                 Key: CALCITE-4295
                 URL: https://issues.apache.org/jira/browse/CALCITE-4295
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.25.0
            Reporter: Zhenghua Gao


If we define a type checker with:

```

OperandTypes.or(

    OperandTypes.variadic(SqlOperandCountRanges.from(3),

    OperandTypes.variadic(SqlOperandCountRanges.from(4))

```

will throw a java.lang.IllegalArgumentException
