> CREATE TABLE ORDERBY_TEST (
> ORGANIZATION_ID INTEGER NOT NULL,

> ENTITY_ID INTEGER NOT NULL,
> CONSTRAINT TEST_PK PRIMARY KEY (
> ORGANIZATION_ID,
> CONTAINER_ID,

> If we execute explain on the following sql:
> {code:borderStyle=solid}
> SELECT ORGANIZATION_ID,SCORE FROM ORDERBY_TEST GROUP BY ORGANIZATION_ID,
> SCORE ORDER BY ORGANIZATION_ID DESC, SCORE DESC
> {code}
> the result is :

> | SERVER AGGREGATE INTO DISTINCT ROWS BY [ORGANIZATION_ID, SCORE] |
> | CLIENT MERGE SORT |
> | CLIENT SORTED BY [ORGANIZATION_ID DESC, SCORE DESC] |
> +----------------------------------------------------------------------+

> from the above explain result, we can see that the ORDER BY ORGANIZATION_ID
> DESC, SCORE DESC is not compiled out,but obviously it should be compiled out
