Re: update table

If I understand you, it would be
insert into table1
select * from table2

You may or may not want to truncate table1 first.

Variation
delete from table1 where pk in (select pk from table2) insert into table1 select * from table2
or
truncate table table1
insert......
or
drop table1
create table1 as select * from table2

etc.
