order by clause not supported
I'm using MariaDB ColumnStore 1.0.8. I want to delete rows using order by clause, but MariaDB says it is not currently supported.
My test cases are belows:
MariaDB [input_test]> delete from test_log where stime < '2017-03-19 00:00:00' limit 1000; Query OK, 1000 rows affected (1.83 sec) MariaDB [input_test]> delete from test_log where stime < '2017-03-19 00:00:00' order by stime limit 1000; ERROR 1815 (HY000): Internal error: DML Statement with order by clause is not currently supported. MariaDB [input_test]> delete from test_log order by stime asc limit 1000; ERROR 1815 (HY000): Internal error: DML Statement with order by clause is not currently supported. MariaDB [input_test]> delete from test_log where stime in (select * from test_log order by stime limit 1000); ERROR 1235 (42000): This version of MariaDB doesn't yet support 'LIMIT & IN/ALL/ANY/SOME subquery'
Are you willing to support this kind of query later? Or is there other way to use delete query with order by clause?
Thank you very much!

I suspect you already filed this in Jira but this is not currently supported but will be consider for future roadmap: https://jira.mariadb.org/browse/MCOL-690
