Review comment:
@wangyum . Could you improve this more because we allow the backtick in
`tableName`?
```scala
scala> sql("create temporary view ab as select 1")
scala> sql("create temporary view ```a``b``` as select 100000")
scala> sql("show tables").show
+--------+---------+-----------+
|database|tableName|isTemporary|
+--------+---------+-----------+
| | `a`b`| true|
| | ab| true|
+--------+---------+-----------+
```
