需要在SQLServer2008中进行帮助查询,sql,sql-server,sql-server-2008,Sql,Sql Server,Sql Server 2008,表格：患者 create table patient ( patientid int, admitdate date , status int , guid int ,flag int) insert into patient (patientid,admitdate,status,guid,flag) values (1,'2013--09-25', 1 ,10,1), (1,'2014--03-25', 1 ,11,2), (1,'2014--04-09', 1 ,12,3), (1

表格：
患者

create table patient ( patientid int,   admitdate date ,  status int  , guid int ,flag int)
insert into patient (patientid,admitdate,status,guid,flag)
values
(1,'2013--09-25', 1 ,10,1),

表2:
患者状态

create table patientstatus ( patientid int , startdate date ,  status int ,guid int,check int)
insert into patientstatus (patientid ,startdate ,status ,guid,check)
values
(1 ,'2013-10-02',2,50,20),

(4 ,'2011-01-02',2,57,27),
(4 ,'2010-07-02',8,58,28)

两个表都有公共列patientid。很少有条件需要满足才能得到输出

患者表

admitdate=p.admitdate
ps.status=2
由ps订购（支票）作为ps
其中p.status=1
p.rowno=1

但上述查询未给出预期结果。请告诉我如何编写查询以在sql server中完成此任务。

当DATEDIFF（day，p.admitdate，s.startdate）<30时，则“更新”
其他“插入”

上述查询未给出预期结果示例表：patient patientid | admitdate | status | guid | flag 1 | 2014--03-25 | 1 | 11 | 2 1 | 2014--04-09 | 1 | 12 | 3表：patientstatus patientid | startdate | status | status | guid | guid | check | check 1 | 2014-04-04-09 | 2 | 51 | 21预期结果admitdate | status | guid | Filter 1 | 2014--03-25 | 1 | 11 | insert 1 | 2014--04-09 | 1 | 51 | update根据您的规则，上述查询是正确的。在上面提供的示例中，您不可能得到“插入”结果，因为您的日期在30天之内。根据您的定义，所有录取日期在开始日期30天内的记录都标记为“更新”。这就是我的疑问。
