Tsql 查询查询结果

对于上面的结果查询（数据透视），我想运行我的另一个select条件

比如说

从“上述数据透视查询结果”中选择（C1和C2）

有可能吗？CTE会帮上忙吗？ SQL Server 2008及以上版本。

请尝试以下操作：

WITH Data AS 
(
  select *
 from 
 (
    select MemId, Condition_id, condition_result
    from t
 ) x
 pivot
 (
    sum(condition_result)
    for condition_id in ([C1], [C2], [C3], [C4])
 ) p
)
SELECT C1, C2
  FROM Data

SQLFiddle:

试试这个：

WITH Data AS 
(
  select *
 from 
 (
    select MemId, Condition_id, condition_result
    from t
 ) x
 pivot
 (
    sum(condition_result)
    for condition_id in ([C1], [C2], [C3], [C4])
 ) p
)
SELECT C1, C2
  FROM Data

SQLFIDLE:

将选择更改为仅选择所需的字段：

select [C1], [C2]
  from 
  (
      select MemId, Condition_id, condition_result
      from t
  ) x
  pivot
  (
      sum(condition_result)
      for condition_id in ([C1], [C2], [C3], [C4])
  ) p
