左右二进制

Question

我按照我所做的二进制文件运行以下脚本来获取左侧和右侧

脚本

select a.ID,a.Node,a.direction,
a.Reference_ID,
a.Recommended_By 
from 
members a
JOIN
members b
ON
a.Node LIKE CONCAT('%(',b.ID,')%')
Where b.ID = 2
order by b.id,a.Recommended_By'

结果

**ID**  **Node**        **Direction**  **Reference**    **Recommended_By**
4   (2)(1)          Left               reem1            2
6   (2)(1)          Right              nevine1          2
9   (4)(2)(1)   Left               ghada1           4
11  (4)(2)(1)   Right              dina2            4
12  (6)(2)(1)   Left               amani2           6
13  (6)(2)(1)   Right              aulla2           6
18  (9)(4)(2)(1)    Left               amani3           9
19  (9)(4)(2)(1)    Right              dina3            9

我需要把CASE语句左右作为列，但我需要它像：

**ID**  **Node**        **Left**  **Right**    **Recommended_By**
4   (2)(1)          reem1                           2
6   (2)(1)                  nevine1         2
9   (4)(2)(1)   ghada1                          4
11  (4)(2)(1)   dina2                           4

前两个记录要按左右排序，但其余记录按照recommended_By进行排序
