Liang-Chi Hsieh updated SPARK-13321:
------------------------------------
Description:
The following SQL can not be parsed with current parser:
{code}
SELECT `u_1`.`id` FROM (((SELECT `t0`.`id` FROM `default`.`t0`) UNION ALL
(SELECT `t0`.`id` FROM `default`.`t0`)) UNION ALL (SELECT `t0`.`id` FROM
`default`.`t0`)) AS u_1
{code}
We should fix it.
The above description is for ANTLR3 parser. As ANTLR4 parser supports it now,
we just need to add test cases.
