## Proposed changes Bug description: In PR #33630, Doris supports auto aggregation for random distributed table, but it not only effects query statements, so if we delete from a random distributed table, will get an error because of unexpectedly rewriting. ``` CREATE TABLE `test_tbl` ( `k` INT NULL, `v` BIGINT SUM NULL ) ENGINE=OLAP AGGREGATE KEY(`k`) DISTRIBUTED BY RANDOM BUCKETS AUTO; mysql > delete from test_tbl where k=1; ERROR 1105 (HY000): errCode = 2, detailMessage = Where clause only supports compound predicate, binary predicate, is_null predicate or in predicate. ``` fix: Check whether it is a query statement before rewriting.
