   3. show create table
   `show create table v`

   ```
   *************************** 1. row ***************************
                   View: v
            Create View: CREATE VIEW `v` AS SELECT 
`default_cluster:default.foo`.`bar` AS `bar` FROM 
`default_cluster:default`.`foo`;
   character_set_client: utf8
   collation_connection: utf8_general_ci
   1 row in set (0.01 sec)
   ```
