How do i club these 2 update stmts into one update

Question

I got a situation like
i want to update table T1 with 2 different flags 260,250
for 2 different colums using a single update
the conditions for these update r almost same but they differ by one condition
which i mentioned below.please suggest some solution.
update T1
set exp_recal=260
where exp_recal not in (250,261,262)
and all other conditions r same
update T1
set estm_recal=250
where estm_recal not in (261,262);
and all conditions in r same as previous

Answer 1

Instead of writing 2 update stmt, i thought we can use in a single update.will this t improve performance or it is best if we write update stmts separately.
As the 2 updates r using the same conditions i thought it will improve performance
if we write in one update.
Thanks for your reply.
Please suggest me which is good.
