MySQL-反转表中的日期跨度；从可用性表创建不可用性表

我有一个可用日期表，我想从中创建一个不可用日期表。看起来应该很简单，可以在php中完成，没有问题，但无法在MySQL查询中完成

源表： （打开是某人签出的日期；关闭是某人签入的日期）

查询应返回：

+------------+------------+
|   checkin  |   checkout |
+------------+------------+
| 2015-12-09 | 2016-01-03 |
| 2016-01-06 | 2016-01-08 |
| 2016-01-15 | 2016-01-16 |
| 2016-02-08 | 2016-02-21 |
| 2016-02-27 | 2016-03-01 |
| 2016-03-06 | 2016-03-10 |
+------------+------------+

谢谢你的帮助

尝试此查询：

SELECT Closes as checkin,
 (SELECT OPENS FROM T WHERE OPENS>T1.Closes ORDER BY OPENS LIMIT 1) as checkout
FROM T T1
WHERE EXISTS (SELECT OPENS FROM T WHERE OPENS>T1.Closes)

SELECT Closes as checkin,
 (SELECT OPENS FROM T WHERE OPENS>T1.Closes ORDER BY OPENS LIMIT 1) as checkout
FROM T T1
WHERE EXISTS (SELECT OPENS FROM T WHERE OPENS>T1.Closes)
