Use of case in an insert statement...

Question

Hi ,
i have an insert statement in a db packaged procedure which needs a case statement to be used.....
I want to use the case in a statement like the following...
insert into x(a,b,c,d,e)
values(a,b,case b='1' then c_val , d_val , null else null , null , e_val);
In other words when the b_value (b column) has value '1' (in the example above) then the values for c , d columns of the tables are those passed as parameters to the procedure . On the other hand , when the the b_value (b column) has not value '1' then the values for c , d columns of the tables should be null and the on the e column another value passed as parameter to the procedure....????
Is the above general syntax of insert correct...????
Many thanks,
Simon

Something like this could do the trick:
insert into x
            (a, b, c, d, e)
     values (a,
             b,
             case
                when b = '1'
                   then c_val
             end,
             case
                when b = '1'
                   then d_val
             end,
             case
                when b = '1'
                   then null
                else e_val
             end
            );
