> > But if the ddl of hive views use some complicated or incompatible grammar, the query might fail. > > Could you list the specific area of influence? Sorry i can not enumerate all fail scenes but i can give an example, if the hive view's definition like this ```CREATE VIEW `test.tbl_test_v` AS select sha(`lh_test`.`number`), `lh_test`.`k1`, `lh_test`.`k2`, `lh_test`.`k3`, `lh_test`.`k4` from `test`.`lh_test` ```, when we create a hive catalog named `hive_ctl` and submit a query like this ```select * from hive_ctl.test.tbl_test_v```, this query will fail and you can see some message like this: ``` MySQL [test_d]> select * from hive_ctl.test.tbl_test_v; ERROR 1105 (HY000): errCode = 2, detailMessage = No matching function with signature: sha(decimal(18, 7)). ```. Above all, a query with hive view will be failed including but not limited to these scenes, **but other queries are not affected.** : - ddl of hive view use some functions that doris dose not contain - ddl of hive view use some grammer that doris does not support -- This is an automated message from the Apache Git Service.
