what are you trying to do not clear. In your code you have specified the IDentity on varchar datatype that does not allow .. indentiy can be set on numeric data.Is your code working? I dont think so it would be working ..For inserting the data see the below example.




DECLARE @var1 TABLE (
a1 int identity,
a2 VARCHAR(100));


insert into @var1 (a2)values('2');

select * from  @var1

also you dont need seperate inserts for inserting column values. you can simply do them in a single statement


insert into @var1 (a1,a2,...a6)
select a1,a2,...,a6 from abc1 where ID = 1
