twdsilva opened a new pull request #2719:
URL: https://github.com/apache/calcite/pull/2719


   …RexCall when possible
   
   SqlRexConvertlets are used to transform a SqlCall into a RexCall while parsing a sql string. A RelNode that is created using RelBuilder does not use the same transformations. This causes the following error while trying to use RelBuilder to create a relnode that use  TIMESTAMPDIFF().
   
   Suppressed: java.lang.RuntimeException: cannot translate call TIMESTAMPDIFF($t8, $t4, $t9)
   at org.apache.calcite.adapter.enumerable.RexToLixTranslator.visitCall(RexToLixTranslator.java:1157)
   at org.apache.calcite.adapter.enumerable.RexToLixTranslator.visitCall(RexToLixTranslator.java:98)
   
   Modify RexBuilder to check if there is a convertlet that exists for the operator being constructed and transform the RexCall using the convertlet.
