CREATE Table A
(StartDate DATETIME,
EndDate DATETIME,
Price float)
CREATE Table B
(EfectiveDate DATETIME,
Item VARCHAR(50))
INSERT INTO A values ('01/20/2016', '11/12/2017', '2.40')
INSERT INTO A values ('11/13/2017', '03/02/2019', '1.20')
INSERT INTO A values ('03/03/2019', '05/22/2019', '2.20')
INSERT INTO A values ('05/23/2019', '07/23/2019', '1.90')
INSERT INTO B values ('06/21/2019' 'Pen')
INSERT INTO B values ('01/01/2018','Pencil')
I need to combine these 2 tables unsing LINQ based on the effective date in table B should be in between StartDate and EndDate in table A
Something like ...
Select * FROM B
INNER JOIN A on B.EfectiveDate BETWEEN A.StartDate AND A.EndDate
OR
from tblB in B
join tblA in A on tblB.B.EfectiveDate BETWEEN tblA.StartDate AND tblA.EndDate
Obviously my LINQ query above is wrong, but I hope you get the idea.
You can't specifically join on BETWEEN
condition
you can try to use a cartesian product and then filter on the appropriate conditions:
from tblB in B
from tblA in A
where tblB.EfectiveDate >= tblA.StartDate && tblB.EfectiveDate <= tblA.EndDate
select new {
StartDate = tblA.StartDate,
EndDate = tblA.EndDate,
Price = tblA.Price,
EfectiveDate = tblB.EfectiveDate,
Item = tblB.Item
};
