Object Type and Bulk Collect/Forall

Question

How can I bulk collect into (and read from) a collection which is a table of an object type such as
CREATE TABLE base_table (
     attr1 NUMBER,
     attr2 NUMBER,
     attr3 NUMBER,
     attr4 NUMBER);
CREATE OR REPLACE TYPE rec_t IS OBJECT (
     attr1 NUMBER,
     attr2 NUMBER,
     attr3 NUMBER,
     attr4 NUMBER);
CREATE OR REPLACE TYPE col_t IS TABLE OF rect;
In my pl sql code I instantiate the collection type and want to populate it with a BULK COLLECT - statemt:
PROCEDURE test IS
v_col col_t;
BEGIN
SELECT rec_T(attr1, attr2, attr3, attr4)
BULK COLLECT INTO v_col
FROM base_table
FORALL i IN v_col.FIRST..v_col.LAST INSERT INTO base_table VALUES (rec_t(v_col(i)));
END;
? If I do it this way I get the following exception on the FORALL insert:
PL/SQL: ORA-00947: not enough values

Answer 1

try like this
CREATE TABLE BASE_TABLE
  ATTR1  NUMBER,
  ATTR2  NUMBER,
  ATTR3  NUMBER,
  ATTR4  NUMBER
CREATE OR REPLACE TYPE rec_t IS OBJECT (attr1 number, attr2 number, attr3 number, attr4 number);
CREATE OR REPLACE TYPE col_t IS TABLE OF rec_t;
CREATE OR REPLACE PROCEDURE test
IS
   v_col   col_t;
BEGIN
       SELECT   rec_t (attr1, attr2, attr3, attr4)
   BULK COLLECT INTO   v_col
         FROM   base_table;
   INSERT INTO base_table
      SELECT   *
        FROM   table (CAST (v_col AS col_t));
END;Regards,
