我正在使用sql2008r2，我需要一份床位入住报告。为此，我刚刚创建了一个视图和这些字段：
registrationid,name,admitdate,dischargedate,accomodationdate,branchid。
我需要结果如分支占用如下：
Date,openingbalance,totaladmission,totaldischarge,Closingbalance。
此处开仓余额意味着，例如，如果我在今天的入住率上报告，那么openbalance是昨天的收盘价。
另外closing balance means Opening +totaladmission-totaldischarge。
我得到totaladmission和totaldischarge。
如何在同一行中获得期初余额？

答案 0 :(得分：0)
如果您创建一个新的日期表，那么您可以像这样获得每天的期初余额：
SELECT
Date
,count(registrationid)
FROM
(
select
*
FROM
Dates as d left outer join
Table as t
on t.admitdate < d.Date
and t.DischargeDate >= d.Date
) as a
GROUP BY
Date
日期表：
Date
------------
01/01/2014 -- start of analysis period
02/01/2014
..
..
31/12/2015 -- end of analysis period
内部查询每个患者/用户每天有一行在该日期之前被录取并在当天或之后出院。
使用该组的外部查询只是按天汇总数据。
要获得期末余额，您只需稍微调整一下，以便在其他连接子句上等于wan：
SELECT
Date
,count(registrationid)
FROM
(
select
*
FROM
Dates as d left outer join
Table as t
on t.admitdate <= d.Date
and t.DischargeDate > d.Date
) as a
GROUP BY
Date
要获取一个表中的所有数据，您可以将多个子查询连接在一起，包括这一个：
SELECT
D.Date
,OpeningBalance
,Admissions
,Discharges
FROM
Dates as D
INNER JOIN
(
SELECT
Date
,count(registrationid) as OpeningBalance
FROM
(
select
*
FROM
Dates as d left outer join
Table as t
on t.admitdate < d.Date
and t.DischargeDate >= d.Date
) as a
GROUP BY
Date
) as OB
on D.Date = OB.Date
INNER JOIN
(
SELECT
Date
,count(registrationid) as Admissions
FROM
(
select
*
FROM
Dates as d left outer join
Table as t
on t.admitdate = d.Date
) as a
GROUP BY
Date
) AS A
on D.Date = A.Date
INNER JOIN
(
SELECT
Date
,count(registrationid) as Discharges
FROM
(
select
*
FROM
Dates as d left outer join
Table as t
on t.DischargeDate = d.Date
) as a
GROUP BY
Date
) AS DC
on D.Date = DC.Date
我确信还有其他方法可以做到这一点，但我喜欢有日期表的可靠性。
