tsql - 如何使用 EXCEPT 插入静态表？

Question

我正在开发一个 SSMS 2008 R2 T-sql 查询。目前我的查询看起来像：

INSERT rd_scs_only_clients
SELECT DISTINCT en.clientid_c
FROM cd.enrollments en 
WHERE en.agency_c in ('SCCR','SCRP') AND DATEDIFF(DAY, GETDATE(), startdate_d) > 90
EXCEPT
SELECT DISTINCT en.clientid_c
FROM cd.enrollments en 
WHERE en.agency_c not in ('SCCR','SCRP')

但这会导致 0 条记录，因为它似乎没有将 INSERT 语句下方的所有代码识别为属于同一查询。我该如何重写这个？

Answer 1

将您的语句包装在 select * from 中，它应该可以工作。

INSERT rd_scs_only_clients

select * from (
SELECT DISTINCT en.clientid_c
FROM cd.enrollments en 
WHERE en.agency_c in ('SCCR','SCRP') AND DATEDIFF(DAY, GETDATE(), startdate_d) > 90
EXCEPT
SELECT DISTINCT en.clientid_c
FROM cd.enrollments en 
WHERE en.agency_c not in ('SCCR','SCRP')
)DATA

Answer 2

试试这个

insert rd_scs_only_clients (yourclientfieldname)
Select * from
(
SELECT DISTINCT en.clientid_c 
FROM cd.enrollments en  
WHERE en.agency_c in ('SCCR','SCRP') AND DATEDIFF(DAY, GETDATE(), startdate_d) > 90 
EXCEPT 
SELECT DISTINCT en.clientid_c 
FROM cd.enrollments en  
WHERE en.agency_c not in ('SCCR','SCRP') 
)v

如果这不起作用，则其他地方可能存在问题。尝试不带插入部分的 SQL
