Is there any way to convert following SQL statement into LINQ?
select ve.EntityID
, fin1.FinanceStat as FinanceStat_New
, fin2.FinanceStat as FinanceStat_Old
from ValuationEvents_PIT_New as ve
left join FinStat_New as Fin1
on ve.EntityID = Fin1.EntityID
left join FinStat_Old as Fin2
on ve.EntityID = Fin2.EntityID
where Fin1.FinanceStat ne Fin2.FinanceStat
and Fin2.FinanceStat is not null
and charindex(Fin1.FinanceStat, 'abc') < 1
and charindex(Fin1.FinanceStat, 'xyz') < 1
Here is my version of it, but I need extra pair of eyes to look at it.
var result = (from ve in valuationEventsPit
join fsn in finStatNew on ve.EntityId equals fsn.EntityID into veFsn
from fin1 in veFsn.DefaultIfEmpty()
join fso in finStatOld on ve.EntityId equals fso.EntityID into veFso
from fin2 in veFso.DefaultIfEmpty()
select new
{
ve.EntityId,
FinStatNew1 = fin1 == null ? null : fin1.FinanceStat,
FinStatNew2 = fin2 == null ? null : fin2.FinanceStat
}).
Where(x => x.FinStatNew1 != null &&
x.FinStatNew2 != null &&
x.FinStatNew1 != x.FinStatNew2 &&
!(x.FinStatNew1.Contains("abc")) &&
!(x.FinStatNew1.Contains("xyz"))).ToList();
The reason I am excluding x.FinStatNew1 == null because of the charindex(Fin1.FinanceStat, 'abc') < 1, which will always return 0 if x.FinStatNew1 is not null and 'abc' or 'xyz' is not there and if x.FinStatNew1 is null then it will return null and condition still will be false (null < 0).
Thanks a lot for your help.
