For a temp view, we should not set the database of the tableIdentifier.
Perhaps we can change the case statement to:
```
case _: NoSuchDatabaseException if db.isDefined =>
u.failAnalysis(s"Table or view not found:
${tableIdentWithDb.unquotedString}, the " +
s"database ${db.get} doesn't exsits.")
```
