Automatic type generation

I have created a function in a PL / SQL package that uses a custom type defined as a table of numbers. I am using an object of this type in a SQL query with a SELECT COLUMN_VALUE statement like this:

Type definition in package:

type T_IDS is table of my_table.col_id%type;

      

Request within the procedure in the package body:

l_ids_list T_IDS ;
begin
select col_ids bulk collect into T_IDS from my_table;
select sum(t.rec_value) into total_value 
          from my_table t where t.col_id in (
            select column_value from Table(l_ids_list) );

      

Everything works fine and when I compile this code I see a new type generated in the schema_name / type section.

Once I installed this in a test environment, it failed to compile with errors:

Error: PLS-00642: Local Collection Types Not Allowed in SQL

Statements Error: PL / SQL: ORA-22905: Cannot Access Rows from a Non-Nested Table Item

Database version (local and test) is the same, 11g. Is there a way to activate this generation in the DBMS?

serve to reproduce:

create table my_table (
col_id number,
rec_value number
);

insert into my_table (col_id, rec_value) values (1,100);
insert into my_table (col_id, rec_value) values (2,200);
insert into my_table (col_id, rec_value) values (3,300);
insert into my_table (col_id, rec_value) values (4,400);

commit;

      

package creation:

create or replace package test_pck as

type T_IDS is table of my_table.col_id%type;

procedure test_list;

end test_pck;
/

create or replace
package body test_pck as

procedure test_list is
  l_ids_list T_IDS ;
  total_value number;
begin
  select col_id bulk collect into l_ids_list from my_table;
  select sum(t.rec_value) into total_value 
            from my_table t where t.col_id in (
              select column_value from Table(l_ids_list) );
end test_list;
end test_pck;
/

what you are doing is wrong. you should create SQL types and not use pl / sql types to access the function TABLE

.

now that WHY does it really sort of worked in your dev env.

The pl / sql table creation problem is for pipelined functions and has been around for a while, but you are using this in a non-pipeline function and, as such, MUST BE FIXED. In 11g release 1 (11.1.0.7 to be precise), however, the bug means it actually compiles. If you actually tried to run it even though you would get the error:

SQL> create package body foo
  2  as
  3
  4    procedure test
  5     is
  6             l_ids_list T_IDS ;
  7             total_value number;
  8     begin
  9             select col_id bulk collect into l_ids_list from my_table;
 10             select sum(t.rec_value) into total_value
 11               from my_table t
 12              where t.col_id in (select column_value from Table(l_ids_list));
 13     end;
 14  end;
 15  /

Package body created.

SQL> exec foo.test;
BEGIN foo.test; END;

now, Oracle FIXED this buggy behavior in 11.2.0.3. now the error occurs at compile time:

in short, create a SQL type with create type

and use this instead:

SQL> create type T_IDS as table of number;
  2  /

Type created.

SQL> create package body foo

  4    procedure test
