helloppx commented on issue #1680: [CALCITE-3621] Push down sort to DB, SQL of Sort rel contains explicit field name instead of * when sort is not top rel URL: https://github.com/apache/calcite/pull/1680#issuecomment-568823430 By the way, when we switch "calcite.enable.enumerable" to "false" without this change, this case will be failed. `java.sql.SQLException: Error while executing SQL "explain plan for select ename from scott.emp order by empno": There are not enough rules to produce a node with desired properties: convention=ENUMERABLE, sort=[1]. Missing conversion is JdbcTableScan[sort: [] -> [0]] There is 1 empty subset: rel#34:Subset#0.JDBC.SCOTT.[0], the relevant part of the original plan is as follows 0:JdbcTableScan(table=[[SCOTT, EMP]])`
