mysql - SQL - 如何选择特定行及其最近的邻居？

Question

例如，我有一个可以按时间排序的表格。现在我想选择我的数据，例如根据时间取一行，其中 column_x = something 和该行的一些最近的邻居(提前给出的具体数字)。在请求中我想选择多行。让我用一个简单的例子来说明:

+------+----------+----------+
| Time | Column_1 | Column_2 |
+------+----------+----------+
|    1 |        0 |        5 |
|    2 |        0 |        6 |
|    3 |        1 |        9 |
|    4 |        1 |        8 |
|    5 |        0 |        5 |
|    6 |        0 |        8 |
|    7 |        0 |        9 |
|    8 |        0 |        6 |
|    9 |        0 |        4 |
|   10 |        1 |        5 |
|   11 |        0 |        2 |
|   12 |        0 |        3 |
|   13 |        0 |        1 |
+------+----------+----------+

我想选择结果数据，使得 COLUMN_1 = 1 和两个最近的邻居。所以我期待的结果是这张表:

+------+----------+----------+
| Time | Column_1 | Column_2 |
+------+----------+----------+
|    1 |        0 |        5 |
|    2 |        0 |        6 |
|    3 |        1 |        9 |
|    4 |        1 |        8 |
|    5 |        0 |        5 |
|    6 |        0 |        8 |
|    8 |        0 |        6 |
|    9 |        0 |        4 |
|   10 |        1 |        5 |
|   11 |        0 |        2 |
|   12 |        0 |        3 |

Answer 1

一个解决方案可能是这样，我不知道这是否是最好的:

select
    time
    ,col_1
    ,col_2
from @tbl
where col_1 = 1
union
select
    t2.time
    ,t2.col_1
    ,t2.col_2
from  @tbl t1
inner join @tbl t2
    on t1.time = t2.time-1
    or t1.time = t2.time-2
where t1.col_1 = 1
union
select
    t2.time
    ,t2.col_1
    ,t2.col_2
from  @tbl t1
inner join @tbl t2
    on t1.time = t2.time+1
    or t1.time = t2.time+2
where t1.col_1 = 1
