BingKun Pan commented on SPARK-42849:
-------------------------------------
Sorry to bother you [~cloud_fan] [~srielau]
Do we need to implement syntax similar to `SHOW VARS LIKE ... `?
Like a temporary view, we have synatx:
```
CREATE TEMPORARY VIEW ...
DROP VIEW ...
| SHOW VIEWS ((FROM | IN) identifierReference)? (LIKE? pattern=stringLit)?
```
Interactive operation may be helpful for end users.
