---------------------------------------
Summary: Modify RexBuilder to use convertlets to transform the
RexCall when possible
Key: CALCITE-5010
URL: https://issues.apache.org/jira/browse/CALCITE-5010
Project: Calcite
Issue Type: Improvement
Components: core
Reporter: Thomas D'Silva
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(){}}}.
{code:java}
Suppressed: java.lang.RuntimeException: cannot translate call
TIMESTAMPDIFF($t8, $t4, $t9)

{code}
Modify RexBuilder to check if there is a convertlet that exists for the
operator being constructed and transform the RexCall using the convertlet.
