Question

我试图选择约束相互矛盾的数据。例如，有一个数据集包含status_desc为＆＃39; 90 - Lost Opportunity＆＃39;当Sproject_Number不为null时。我想过滤两次，所以首先我将所有Sproject_number都设为null然后我能够再次过滤此查询以获得一个表格，其中status_desc是＆＃39; 90-Lost Opportunity＆＃39;

SELECT ProjectNumber,
       PName
FROM
(
    SELECT DISTINCT
           T0.project_number_ext AS ProjectNumber,
           T0.project_key AS PKey,
           T0.sproject_number AS sPNumber,
           T0.project_number AS PNumber,
           T0.schedule_finish AS SFinish,
           T0.status_desc AS SDesc,
           T0.Project_name AS PName
    FROM trimergo.rpt_getProjectPOC T0
    WHERE T0.sproject_number IS NULL
)
GROUP BY ProjectNumber,
         PName;

Answer 1

我想你只需要这个。子查询不需要。

Answer 2

这段代码有效，我试图选择约束相互矛盾的数据。例如，当Sproject_Number不为null时，有一些数据集包含status_desc为'90 - Lost Opportunity'。我想过滤两次，所以首先我得到所有的空数据集，然后我过滤该查询以关闭我需要的数据集

SELECT
T1.ProjectNumber , T1.PName, T1.SDesc

FROM
( 

SELECT DISTINCT 
 T0.project_number_ext as ProjectNumber
,T0.project_key as PKey
,T0.sproject_number as sPNumber 
,T0.project_number as PNumber
,T0.schedule_finish as SFinish
,T0.status_desc as SDesc
,T0.Project_name as PName

From trimergo.rpt_getProjectPOC T0

WHERE T0.sproject_number IS NULL ) AS T1

Where T1.SDesc LIKE '10 - In Proposal%'
OR T1.SDesc like '90-Lost Opportunity%'

Group by ProjectNumber, PName, SDesc

如何使用子查询过滤两次？
