LakeShen updated CALCITE-5906:
------------------------------
Description:
Currently in the RelToSqlConverter class, there is no visit method to handle
the Sample RelNode.If a SQL plan has Sample RelNode, RelToSqlConverter will
throw a AssertionError like this:
{code:java}
java.lang.AssertionError: Need to implement org.apache.calcite.rel.core.Sample
{code}
This will cause the Sample RelNode plan to fail to translate to the
corresponding dialect.
