The
progression is also supported for implicit query in a DML statement via the returning
keyword…
declare

index by binary_integer;

index by binary_integer;
salaries salaries_t;

for j in employee_ids.first..employee_ids.last
loop

end loop;
end;
…then…forall j in employee_ids.first..employee_ids.last
update employees set salary = salary*1.1

returning salary bulk collect into salaries
/* this is not a typo: employee_ids is subscipted but salaries isn't */;…then…

execute immediate 'update employees set salary = salary*1.1'
