Hi all,

Does anyone have any sample on multiple sql statements in one stored procedure?? but the results capture is based on the results of the previous sql statement.

Eg Statement 1: select id from table where condition applies;

Statement 2: select distinct address from table where stud_id = id(which is retrieved from the first statement);

Statement 3: select distinct country from table where add = address(which is retrieved from the second statement);

How can I do about it?? Can anyone help me?? Thanks alot.

you can use EXPLICITY CURSORS as shown here (very flexible) OR IMPLICIT CURSORS (just sql).
SQL> ed
Wrote file afiedt.buf

  1  create or replace procedure tnov5
  2  as
  3  dno dept.deptno%type;
  4  cursor c1 is select * from dept;
  5  cursor c2 is select * from emp where deptno=dno;
  6  begin
  7     for mag1 in c1 loop
  8             exit when c1%notfound;
  9             dno:=mag1.deptno;
 10             for mag2 in c2 loop
 11                     exit when c2%notfound;
 12                     dbms_output.put_line(mag2.ename||','||mag2.deptno||','||mag1.loc);
 13             end loop;
 14     end loop;
 15* end;

hi.. can i ask you some questions??
what are you trying to do at this line??
dno dept.deptno%type;

the mag1 and mag2 are variables?? do not need to declare??

by the way, extra one question on my mind.. Can procedure return resultsets back to my jsp pages if my jsp page calls for the procedure??

Sorry to ask you so much. :)
Thanks for your help.

hi.. I make something out.. but didnt display me anything just put procedure successfully completed.. How can I know it had gotten the results I wan.. Here is my procedure

CREATE OR REPLACE PROCEDURE sp_procedure(yearVar IN integer, etyVar IN varchar, optVar IN varchar, valVar IN integer)
AS
cp table.cost_id%TYPE;
ety table.entity%TYPE;
mth table.month%TYPE;
CURSOR cursor1 is SELECT cost_id FROM table WHERE year = yearVar and entity = etyVar and optVar = 'valVar';
BEGIN
OPEN cursor1;
LOOP
FETCH cursor1 INTO cp;
EXIT WHEN cursor1%notfound;
dbms_output.put_line(cp);
END LOOP;
CLOSE cursor1;
END sp_procedure;

Do you think it will capture anything?? I scare that it would be the same as my function capture no data.
