Unfortunately that will set a to b and leave b as is, you need a swap column ...
-- add swap column
alter table add column swap (same type as a & b)
-- standard swap 3-stepswap
alter table table1 set swap=a, a=b, b=swap;
-- check
select a,b from table1;
-- lose the swap col
alter table table1 drop column swap;
