Question

我正在开发SSMS 2008 R2 T-sql查询。目前我的查询如下：

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')

但这导致0条记录，因为它似乎没有将INSERT语句下面的所有代码都识别为属于同一查询。我怎么能改写这个？

Answer 1

在select * from中包装您的语句，它应该可以正常工作。

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

如果不起作用，其他地方可能会出现问题。尝试没有插入部分的SQL

如何使用EXCEPT插入静态表？
