SQL & PL/SQL

Hi All,

i am using a forall to insert data into a table..
however when i do the insert, i need to check if one column is not null...

but when i am trying to do it , i am getting an exception saying that dml should follow FORALL.

is there any way to do this?? for instance,

forall c in type_emp.first..type_emp.last
if (COndition satisfied) then
insert into table
end if;
