Hi experts,

DECLARE
--TYPE NameList IS TABLE OF VARCHAR2(15);
TYPE NameList IS TABLE OF employees.ename%type;
--cursor c1 is select ename from employees where 1=2;
TYPE NameList IS TABLE OF c1%rowtype;
enames NameList;
sql_stmt VARCHAR(200);
BEGIN
sql_stmt := 'UPDATE employees SET salary=salary+10 RETURNING ename INTO :2';
EXECUTE IMMEDIATE sql_stmt
RETURNING BULK COLLECT INTO enames;
forall i in enames.first..enames.last
insert into t1(ename) values(enames(i));
END;
/
The above code is working fine but i want to store multiple ( 8 ) columns in "T1" table so how i can do it???

You can use several arrays:
SQL> DECLARE
2 TYPE NameList IS TABLE OF employees.last_name%TYPE;
3 names NameList;
4 TYPE SalList IS TABLE OF employees.salary%TYPE;
5 sals SalList;
6 dept_id NUMBER := 30;
7 BEGIN
8 UPDATE employees SET salary = salary * 1.1
9 WHERE department_id = 30
10 RETURNING last_name, salary
11 BULK COLLECT INTO names, sals;
12
13 DBMS_OUTPUT.PUT_LINE ('Updated ' || SQL%ROWCOUNT || ' rows:');
14 FOR i IN names.FIRST .. names.LAST
15 LOOP
16 DBMS_OUTPUT.PUT_LINE ('Employee ' || names(i) || ': ' || sals(i));
17 END LOOP;
18 ROLLBACK;
19 END;
20 /
Updated 6 rows:
Employee Raphaely: 12100
Employee Khoo: 3410
Employee Baida: 3190
Employee Tobias: 3080
Employee Himuro: 2860
Employee Colmenares: 2750
PL/SQL procedure successfully completed.
Or you can use a record:
SQL> DECLARE
2 TYPE EmpRec IS RECORD (last_name employees.last_name%TYPE,
3 salary employees.salary%TYPE);
4 emp_info EmpRec;
5 emp_id NUMBER := 100;
6 BEGIN
7 UPDATE employees SET salary = salary * 1.1
8 WHERE employee_id = emp_id
9 RETURNING last_name, salary INTO emp_info;
10 DBMS_OUTPUT.PUT_LINE
11 ('Just gave a raise to ' || emp_info.last_name ||
12 ', who now makes ' || emp_info.salary);
13 ROLLBACK;
14 END;
15 /
Just gave a raise to King, who now makes 26400
PL/SQL procedure successfully completed.
As exercise, I let you mix both examples.
Please post the solution you'll find for future readers (or the error you'll get, we can learn from errors).
