Julian Hyde commented on CALCITE-5906:
--------------------------------------

The PR looks good. Can you rebase it onto main (which now contains CALCITE-5895 
and CALCITE-5916). Also change the summary (and commit message, and 
descriptions of test cases) so that it reads like a feature request, something 
like "JDBC adapter should generate TABLESAMPLE".

> 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.
