RE: Handle Multiple Rows Without Loops
|
If we want to return multiple row from a function then we can use ref cursor
function .Example is given below:
create or replace function f1 return sys_refcursor as
r1 sys_refcursor;
begin open r1 for select * from emp;
return(r1);
end;
call the
function as :select f1 from
dual; then it returns :
CURSOR STATEMENT : 1CURSOR STATEMENT : 1 EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO
