      • inferOperandTypes

        void inferOperandTypes​(SqlCallBinding callBinding,
                               RelDataType returnType,
                               RelDataType[] operandTypes)
        Infers any unknown operand types.
        callBinding - description of the call being analyzed
        returnType - the type known or inferred for the result of the call
