Oracle-update multiple row value where the the id column equals specific values -


i new in oracle , want update multiple row value column id = 1 , 2.

i tried : 

update tester  set employee_phone_number = ( 0789456123,0789456321)   employee_id in (1,2);

but gives me "missing right parenthesis"

any please , in advance.

another approach:

merge   tester using (   select 1 id,'0123456785' employee_phone_number dual union   select 2 id,'0123456786' employee_phone_number dual) new_values on (   tester.id = new_values.id) when matched update    set employee_phone_number = new_values.employee_phone_number;

more words, allows values specified in 1 place , extends allow inserts id not exist.
