> As discussed in CALCITE-5118, {{SqlOperator#rewriteCall}} is done before validation, which is hard to give accurate validation messages. We prefer to use {{SqlRexConvertlet}} to do this work, hence we can make the validation error more accurate, and does not give more burden to the optimization phase.
> We should deprecate {{{}SqlOperator#rewriteCall{}}}, and move these rewriting logic to {{SqlRexConvertlet.}}
> Currently, {{{}SqlCoalesceFunction{}}}, {{{}SqlDatePartFunction{}}}, {{{}SqlJdbcFunctionCall{}}}, {{{}SqlNewOperator{}}}, {{{}SqlNullifFunction{}}}, {{SqlProcedureCallOperator}} used this mechanism, we should handle these functions in this issue.
