Merging two tables

SQL 7
How do I merge two table's records? In other words, merge
T1 into T2. There are records in both tables that are the
same, but where T1 has a record that T2 doesn't have,
T1's record needs to be inserted into T2.
I've been reading Join syntax til my head is spinning.
Thanks,
DonInsert into T2
select * from T1 where T1.PrimaryKey
where T1.PrimaryKey NOT IN (Select PrimaryKey from T2)
Replace PrimaryKey with the unique priamry key from each table.

insert T2
select * from T1
where not exists (select * from T2 where T1.keycol = T2.keycol)
