We do not support select myCatalog.myTable.myField from myCatalog.myField;

[roclas]

MySQL supports queries of this kind:
select myCatalog.myTable.myField from myCatalog.myField;

E.g:
mysql> select test.Users.email from test.Users;
+------------------+
| email |
+------------------+
| carlos@mymail.com |
| jj@myemail.com |
+------------------+
2 rows in set (0.01 sec)

Maybe we could suport it too?
