------------------------------------------

             Summary: StandardConvertletTable#convertDatetimeMinus is inconsistent with MINUS_DATE return type inference
                 Key: CALCITE-4397
                 URL: https://issues.apache.org/jira/browse/CALCITE-4397
             Project: Calcite
          Issue Type: Bug
          Components: core
    Affects Versions: 1.26.0
            Reporter: Vladimir Sitnikov


SqlNode representation has 3 parameters: {{datetime}} - {{datetime}} {{interval_qualifier}}
The return type inference is {{ARG2_NULLABLE}} so it assumes the call has three parameters.

In practice, {{convertDatetimeMinus}} removes the last parameter via {{rexBuilder.makeCall(resType, op, exprs.subList(0, 2));}}, which blocks node cloning via {{rexBuilder.makeCall(e.getOperator(), operands)}}
