Question

我在一个名为#MPR的表中有一组记录。我想要完成的是在该表中找到在另一个名为#Lookup的表中具有重叠日期的记录，并且具有匹配的ProviderID，Sub Type，CauseID和CircuitID。如果是，则返回#MPR表中的所有记录以及#Lookup表中相应的重叠记录，其中包含以下列LookupID，BegDate，EndDate和Amt。

-- Create Temporary Table
CREATE TABLE #MPR

(
MprID int IDENTITY(1,1),
ProviderID int,
RowNo int,
SubType varchar(50), 
CauseID int,
CircuitID int,
BegDate date,
EndDate date,
Amt decimal(11,2),
Remarks varchar(max)
)

--Insert records

INSERT INTO #MPR  VALUES(673,2,'Original',439,4852,'2016-12-01','2016-12-31',100,'Rec A')
INSERT INTO #MPR VALUES(673,15,'Original',439,4852,'2016-12-21','2016-12-31',200,'Rec B')
INSERT INTO #MPR VALUES(100,21,'Original',500,5000,'2016-12-01','2016-12-01',300,'Rec C')
INSERT INTO #MPR VALUES(673,24,'Original',439,4852,'2016-12-05','2017-01-31',400,'Rec D')

-- Create Temporary Table
CREATE TABLE #Lookup

(
LookupID int IDENTITY(1,1),
ProviderID int,
SubType varchar(50), 
CauseID int,
CircuitID int,
BegDate date,
EndDate date,
Amt decimal(11,2),
)

--Insert records
INSERT INTO #Lookup  Values(673,'Original',439,4852,'2016-10-01','2016-10-31',200.00)
INSERT INTO #Lookup Values(100,'Original',500,5000,'2016-10-01','2016-10-31',200.00)
INSERT INTO #Lookup Values(100,'Original',500,5000,'2016-10-01','2016-11-30',200.00)
INSERT INTO #Lookup Values(673,'Original',439,4852,'2016-11-01','2016-11-30',200.00)
INSERT INTO #Lookup Values(673,'Original',439,4852,'2016-12-01','2016-12-31',200.00)
INSERT INTO #Lookup Values(673,'Original',439,4852,'2017-01-01','2017-01-31',200.00)
INSERT INTO #Lookup Values(100,'Original',500,5000,'2016-12-01','2016-12-31',200.00)
INSERT INTO #Lookup Values(673,'Original',439,6565,'2017-01-01','2017-01-31',200.00)

--Drop table #mpr
--Drop table #Lookup

我的结果：

Answer 1

如果我已正确阅读您的规格，这将做您想要的。请注意，到目前为止，它仅使用两个条件而不是另一个条件中的四个条件。

SELECT
   m.*,
   l.LookupId,
   l.BegDate,
   l.EndDate,
   l.Amt
FROM
   #MPR m
   INNER JOIN #Lookup l
      ON m.ProviderID = l.ProviderID
      AND m.SubType = l.SubType
      AND m.CauseID = l.CauseID
      AND m.CircuitID = l.CircuitID
WHERE
   m.BegDate < l.EndDate
   AND l.BegDate < m.EndDate
;

Answer 2

我认为这会做你想做的事情

select * 
from #mpr M 
inner join #Lookup L 
on M.ProviderID = L.ProviderID 
AND M.SubType = L.SubType 
AND M.CauseID = L.CauseID 
AND M.CircuitID = L.CircuitID
AND (M.BegDate BETWEEN L.BegDate AND L.EndDate OR L.BegDate BETWEEN M.BegDate AND M.EndDate)
