I have this code snippet below,

CURSOR MCUR_CHECKEXIST(SC IN VARCHAR2, DT IN DATE) 
    IS 
    SELECT 
        BASIC_AMOUNT 
    FROM 
        AL_DS_BASIC 
    WHERE 
        SALES_CODE= SC 
        AND 
        to_char(REPORT_PERIOD,'MMYYYY')= to_char(DT,'MMYYYY');

OPEN MCUR_CHECKEXIST(PI_SALES_CODE, PI_DATE);
IF (MCUR_CHECKEXIST%NOTFOUND) THEN
  -- Do something here
END IF;


Can I do the checking (MCUR_CHECKEXIST%NOTFOUND) without doing the fetching operation (the checking statements above still result to boolean TRUE or FALSE) ??

Thanks in advance

Hi,

I believe that it is only when the fetch is executed that the %NOTFOUND is then set.

Opening the cursor just parses the SQL and binds the variables.

What are you trying to achieve here?

hi,

may be something like this
declare
cursor c1(v_deptno number) is
select ename,sal from emp where deptno=v_deptno;
begin
open c1(2);
if c1%notfound then
dbms_output.put_line('found');
else
dbms_output.put_line('not found');
end if;
end;


but what are you trying to achive here


regards,

You have to fetch to get %found/%notfound attribute set:
SQL> declare cursor c is select * from t;
  2  begin
  3    open c;
  4    if c%notfound then dbms_output.put_line('not found');
  5    elsif c%found then dbms_output.put_line('found');
  6    else dbms_output.put_line('unknown'); end if;
  7  end;
  8  /
unknown

PL/SQL procedure successfully completed.

SQL> select count(*) from t;
  COUNT(*)
----------
         0

1 row selected.

Regards
Michel
