Question

我正在尝试使此代码正常工作。我需要11条记录，但此查询得到28条记录。通过取消注释约会我可以得到11分，但记录有误。括号中的AND子句似乎无法过滤。谁能给我关于我做得不好的想法？（不是最好的工作）：

create table #enc
(birthdate date,pidd numeric(19), id numeric(20),lastn varchar(30),firstn 
varchar(30), cdate date)

insert into #enc
select pp.Birthdate,PP.PID, pp.patientprofileid, pp.last, pp.first, 
cast(CAST(DateAdd(s, CAST(Left(d.CLINICALDATE,Len(d.CLINICALDATE)-6) AS 
DECIMAL(20,0)),'Jan 01 1960') AS DATE) as DATE) as visit
 FROM DOCUMENT d
--INNER JOIN Appointments a
--ON d.AppointmentsId = a.AppointmentsId
INNER JOIN PatientVisit v
ON d.PatientVisitId = v.PatientVisitId
inner join patientprofile pp on pp.PId = d.PID
inner join ORDERS o on o.PID= pp.PId
inner join ORDERCODES oc on oc.CODE = o.CODE

where DOCTYPE in(1)  and d.status in( 's','u','h','a') and d.USRID 
=xxxxx

((((and  o.CODE not in('00100','00103','00110','00113','00126'))))

 and oc.ORDERTYPE not in('t')

AND CAST(VISIT AS DATE) BETWEEN '10/01/2018' AND '10/31/2018' 



 select distinct cdate, * from #enc order by lastn

可能“文档”表和“约会”表具有多对多关系，这意味着一个文档可能链接了多个约会记录。这将导致重复的记录。试试这个：

create table #enc
(birthdate date,pidd numeric(19), id numeric(20),lastn varchar(30),first 
 nvarchar(30), cdate date)

insert into #enc
select 
    pp.Birthdate,PP.PID, pp.patientprofileid, pp.last, pp.first, 
    cast(CAST(DateAdd(s, CAST(Left(d.CLINICALDATE,Len(d.CLINICALDATE)-6) AS DECIMAL(20,0)),'Jan 01 1960') AS DATE) as DATE) as visit
FROM DOCUMENT d
INNER JOIN ( 
    select distinct AppointmentsId from Appointments
) a ON d.AppointmentsId = a.AppointmentsId
INNER JOIN PatientVisit v
ON d.PatientVisitId = v.PatientVisitId
inner join patientprofile pp on pp.PId = d.PID
inner join ORDERS o on o.PID= pp.PId
inner join ORDERCODES oc on oc.CODE = o.CODE

where DOCTYPE in(1)  and d.status in( 's','u','h','a') and d.USRID 
=xxxxx

((((and  o.CODE not in('00100','00103','00110','00113','00126'))))

 and oc.ORDERTYPE not in('t')

AND CAST(VISIT AS DATE) BETWEEN '10/01/2018' AND '10/31/2018' 



 select distinct cdate, * from #enc order by lastn

我需要弄清楚：使SQL AND运算符起作用
