MySQL UNION：如何获取两列中的数据

Question

我有这样的SQL：

SELECT COUNT(*) as "With Gold"  FROM user_accounts_gold WHERE level = 6
UNION
SELECT COUNT(*) as "No Gold"    FROM user_accounts_bronze WHERE level = 6

目前输出：

| With Gold |
-------------
| 17734     |
| 2388      |

有没有办法让它像这样输出：

| With Gold | No Gold |
----------------------
| 17734     | 2388    |

谢谢

做一个CROSS JOIN代替：

select * from
(SELECT COUNT(*) as "With Gold"  FROM user_accounts_gold WHERE level = 6) ug
CROSS JOIN
(SELECT COUNT(*) as "No Gold"    FROM user_accounts_bronze WHERE level = 6) ub
