A question on FORALL and Collections

Question

It's hard to find a difinitive answer to this question via online docs. I'm doing a FORALL without a BULK COLLECT.
Givin the following;
In Package Header:
TYPE scalarArray1 is varray(500) of varchar2(50);
TYPE scalarArray2 is varray(500) of varchar2(50);
In package Body
...populate the 2 arrays
FORALL i in 1..N
EXECUTE IMMEDIATE
'UPDATE table_name SET column1 = :1
WHERE column2 = :2'
USING scalarArray1(i), scalarArray1(i);
This will give me the following error:
PLS-00430: FORALL iteration variable is not allowed in this context
PLS-00435: DML statement without BULK In-BIND cannot be used inside FORALL
I'm begining to think that you can't have for FORALL statment without at BULK COLLECT statement.
I'm I correct?

Answer 1

You defined VARRAY types, now you need to declare variables of those types and use the variables.
SQL> create table t (
  2    column1  varchar2(30),
  3    column2  varchar2(30) );
Table created.
SQL>
SQL> insert into t
  2  select 'a' column1, 'y'||level column2
  3    from dual
  4  connect by level <= 12;
12 rows created.
SQL>
SQL> commit;
Commit complete.
SQL> select * from t;
COLUMN1                        COLUMN2
a                              y1
a                              y2
a                              y3
a                              y4
a                              y5
a                              y6
a                              y7
a                              y8
a                              y9
a                              y10
a                              y11
a                              y12
12 rows selected.
SQL> DECLARE
