Hi Alberto,
thanx for your valuable suggestion. but still i have doubt. the code which i have mentioned above might be simple but what if i have big requirement where i need update the data by using loops and conditional statement.
and i have similar kind of requirement where i need to deal with procedure which returns more than one row
my source is
empno ename salary
111,abhi,300
112,arti,200
111,naveen,600
here i need to write a store procedure which accepts the empno (111) as input para and display ename and salary
here i have written store procedure like this
create or replace procedure show_emp_det(p_empno in emp.empno%type, p_ename out emp.ename%type,p_salary out emp.salary%type, p_cursor out sys_refcursor)
is
begin
open p_cursor for
select ename,salary into p_ename,p_salary from emp where empno=p_empno;
end;
and i have called this by using
declare
p_salary emp.salary%type;
p_ename emp.ename%type
v_cursor sys_refcursor;
begin
show_emp_det(111,p_ename,p_salary,v_cursor);
fetch v_cursor into p_ename,p_salary;
dbms_output.put_line(p_ename);
dbms_output.put_line(p_salary);
end;
here i should get
abhi,300
naveen,600
but i am getting first row only
abhi,300
but i want to fetch both rows...pls help me to find the solution
