Hello Everyone,

I need one query help


create table #temp1
(
StudentLocalID varchar(9),
EnrollSchoolCode Varchar(3)
)

create table #temp2
(
StudentLocalID varchar(9),
ScheduleSchoolCode varchar(3)
)
insert into #temp1 values ('003682153','305')
insert into #temp1 values('003682153','303')
insert into #temp1 values('003744930','305')
insert into #temp1 values('003744930','332')

insert into #temp2 values('003682153','305')
insert into #temp2 values('003682153','303')
insert into #temp2 values('003744930','305')
insert into #temp2 values('003744930','303')
insert into #temp2 values('003744930','332')





I need to display unmatch ScheduleSchoolCode from EnrollSchoolCode of #temp2 only
so desired output is


StudentLocalID ScheduleSchoolCode
003744930 303

Ok, I didnt realise there was any other logic.

This is a way to do it with a Left Join


Select t2.*
from #temp2 t2
Left Join #temp1 t1 on t2.StudentLocalID=t1.StudentLocalID and t2.ScheduleSchoolCode=t1.EnrollSchoolCode
where
t1.EnrollSchoolCode is Null




Heres a way with a Not Exists


Select t2.*
from #temp2 t2
Where
NOT EXISTS (Select 1 from #temp1 t1
Where t1.EnrollSchoolCode=t2.ScheduleSchoolCode
and t1.StudentLocalID=t2.StudentLocalID)



Either should enable you to add more logic.

I already provided that solution but the poster needs to add more logic so I've provided the additional solutions, which should allow for more logic to be provided.
