08:44:23 2 is
08:44:23 3 begin
08:44:23 4 update emp set sal = sal * (1 + perc/100);
08:44:23 5 return perc;
08:44:23 6 end;
08:44:25 7 /

Function created.

08:44:26 ==> create or replace procedure sp_test_update is
08:44:40 2 my_perc number;
08:44:55 3 begin
08:44:55 4 my_perc := sf_update_sal(10);
08:44:55 5 end;
08:44:56 6 /
