> As for sql :
> {code:java}
> String query = "SELECT row_number() over (order by \"hire_date\") FROM \"employee\"";
> {code}
> using RelToSqlConverter  to generate a sql for mysql , the result is :
> {code:java}
> SELECT ROW_NUMBER() OVER (ORDER BY `hire_date` NULLS LAST)
> FROM `foodmart`.`employee`
> {code}
> However, mysql does not support NULLS LAST.
