I want simple join for

a) Values that are in temp1 and not in temp2
b) Values that are in temp2 and not in temp1

Answer 1

Well depends on what your match criteria are. This assumes A is a unque id you can use, if not add more to the on clauses.

Select 'In Temp1 but not temp2',temp1.*
From Temp1 
Outer Join Temp2 On temp1.A = temp2.A Where temp2.A is null
Union
Select 'In Temp2 but not temp1',temp2.*
From Temp2 
Outer Join Temp1 On temp2.A = temp1.A Where temp1.A is null
