PL/SQL array passed to SQL IN

Question

Hi,
I have a PL/SQL array which type is defined like this:
create or replace type type_id_array as table of number(6, 3);
then i create a variable and initilaize:
var_1 type_id_array;
var_1 := .....
then i have a select statement.
select * from table t where t.id in(var_1)
That's it, i want to use the array in an SQL in. This seems not possible.
Can you explain why? Any alternate solutions?
Thanks

Can you explain why? Any alternate solutions?SQL supports set commands specifically for arrays (in addition to the using the TABLE() method mentioned). For example:
SQL> create or replace type TNumbers is table of number;
  2  /
Type created.
SQL>
SQL> declare
  2          numList TNumbers;
  3          cnt     integer;
  4  begin
  5          numList := new TNumbers(1,2,3,4,5,6,7);
  6          select
  7                  count(*) into cnt
  8          from    user_objects
  9          where   TNumbers(object_id) member of numList;
10          DBMS_OUTPUT.put_line( 'cnt='||cnt );
11  end;
12  /
cnt=0
PL/SQL procedure successfully completed.Obviously there are performance considerations when using arrays/collections in SQL. So before choosing a method, evaluate the performance.
