Answer / deepak

Just copy all data in T1 from T4.

insert into T1 (select * from T4)

Now do this assuming 'dateCol' contains the date:

delete from T4
insert into T4 (select * from T3)
delete from T3
insert into T3 (select * from T2)
delete from T2
insert into T2 (select * from T1 where year(dateCol) = 2002)
delete from T1 where year(dateCol) = 2002

This should move the data around without using temp table.
