How to reverse where clause condition? please

Question

Hello Good Morning,
i have below query which is working fine,
update t
set skipjet='Yes'
from  mytable t join mychildtable C on t.ssn=c.ssn
where
t.ChannelCd ='OB Calls' AND t.PlanBlance BETWEEN c.MinSalary  AND  c.MaxSalary
but my problem here is, i have to set skipjet='Y' when the above where clause not met (like opposite way)
Please advise?
Thank you in Advance

Dear Milano, 
I did an example and i got the result that you needed.
declare @mytable table (ssn int,ChannelCd varchar(50),PlanBlance money,skipjet varchar(3))
declare @mychildtable table (ssn int,MinSalary money,MaxSalary money)
insert into @mytable(ssn,ChannelCd,PlanBlance,skipjet) values (1,'OB Calls',800.00,'NO')
insert into @mytable(ssn,ChannelCd,PlanBlance,skipjet) values (1,'OB Calls2',800.00,'NO')
insert into @mychildtable(ssn,MinSalary,MaxSalary)values(1,600.00,800.00)
update t set skipjet='Yes'
from
@mytable t
where
not exists (
Select * from
@mychildtable C
where
t.ssn=c.ssn and
t.ChannelCd ='OB Calls' AND
t.PlanBlance BETWEEN c.MinSalary AND c.MaxSalary
Select * from @mytable
Result:
ssn         ChannelCd                                      PlanBlance           skipjet
1           OB Calls                                           800,00                NO
1           OB Calls2                                         800,00                Yes
