编写一个 SQL 查询，查找所有至少连续出现三次的数字。

+----+-----+| Id | Num |+----+-----+| 1 | 1 || 2 | 1 || 3 | 1 || 4 | 2 || 5 | 1 || 6 | 2 || 7 | 2 |+----+-----+

例如，给定上面的 Logs 表， 1 是唯一连续出现至少三次的数字。

+-----------------+| ConsecutiveNums |+-----------------+| 1 |+-----------------+

# Write your MySQL query statement belowselect distinct l1.num ConsecutiveNums from Logs l1 join Logs l2 on l1.id=l2.id-1 join Logs l3 on l1.id=l3.id-2 where l1.num=l2.num and l2.num=l3.num
