In this post, I am giving an example to perform an insert into using Oracle Bulk Collect and FORALL command. Created a PL SQL function which will take data from EMP table using a cursor then creates type array variable of that cursor row type and then it bulk collect and insert into BONUS table using FORALL.
Below is the example:
CREATE OR REPLACE FUNCTION f_currowtype RETURN BOOLEAN IS CURSOR c_emp IS SELECT empno, ename, job, sal FROM emp; TYPE t_emp IS TABLE OF c_emp%ROWTYPE; e_rec  t_emp; BEGIN OPEN c_emp; FETCH c_emp BULK COLLECT INTO e_rec; CLOSE c_emp; FORALL i IN e_rec.FIRST .. e_rec.LAST insert into bonus (empno, amount) values (e_rec(i).empno, e_rec(i).sal * 10 / 100); DBMS_OUTPUT.put_line ('Rows inserted: ' || SQL%ROWCOUNT); COMMIT; RETURN TRUE; EXCEPTION WHEN OTHERS THEN ROLLBACK; RETURN FALSE; END;
You can execute it as below:
SET SERVEROUTPUT ON; BEGIN IF f_currowtype THEN DBMS_OUTPUT.put_line ('Success'); ELSE DBMS_OUTPUT.put_line ('Failed'); END IF; END;
