Using Arrays in SELECT BULK queries

Question

Dear All,
Can we use arrays in the SELECT Bulk operations.
Example:
SELECT empno BULK COLLECT INTO v_empno FROM EMP WHERE deptno = v_deptno(m);
Is there any way we can simulate this example.
Appreciate your response on this one.
Thanks,
Madhu K.

Answer 1

Yes you can. See the example.
SQL> set serverout on
SQL> declare
  2  TYPE varr_typ IS VARRAY(2) OF NUMBER;
  3  my_varr varr_typ:=varr_typ(20) ;
  4  TYPE rec_typ IS RECORD (fname EMPLOYEES.First_Name%TYPE,
  5                          lname EMPLOYEES.LAST_NAME%TYPE);
  6  TYPE tmp_tbl IS TABLE OF  rec_typ;
  7  my_tbl  tmp_tbl;                     
  8  BEGIN
  9  --my_varr(1):=20;
10  SELECT FIRST_NAME,LAST_NAME
11  BULK COLLECT INTO my_tbl
12  FROM EMPLOYEES
13  WHERE department_id=my_varr(1);
14 
15  FOR i IN 1..my_tbl.COUNT LOOP
16    DBMS_OUTPUT.put_line(my_tbl(i).fname||' '||my_tbl(i).lname);
17    END LOOP;
