RE: Help - How to declare a cursor inside a FOR ... LOOP ?

i speak from ignorance, isn't there implicit and explicit cursor declarations and usage? can't you encapsulate that section you have identified in a loop and it will implicitly opens a cursor? then all you have to do is manipulate as needed to generate desired results...

You can't. It appears that you want to select all the detailed text extries related to a specific problem. You could define a cursor that selects all the detailed entries, or you could read all the detailed entries into a pl/sql table and then search through them. If you use the cursor, then you have to reopen the cursor for each new problem.

Hey, Guys:

I need to decalre a cursor inside a FOR .. LOOP, because the variables in SELECT statement for the CURSOR are coming from FOR .. LOOP. How could I do this?

DECLARE
V_AKTIV_NR    aktiv.AKTIV_NR%TYPE;
V_PROBLEM    aktiv.PROBLEM%TYPE;
V_ENDDAT   aktiv.ENDDAT%TYPE;
V_ENDUHR   aktiv.ENDUHR%TYPE;
V_AUSSAGEW   aktiv.AUSSAGEW%TYPE;
V_LANGTEXT   aktiv.LANGTEXT%TYPE;
V_LONGTEXT    VARCHAR2(20000);
V_LONGTEXT_CUR VARCHAR2(13000);
V_LONGTEXT_TRIM VARCHAR2(2000);
p_PROBLEM    PROBLEM.PROBLEM%TYPE;

############# This part need to be inside FOR.. LOOP, otherwise, I wouldn't get anything.

    CURSOR AKLangTextCur IS
SELECT TO_CHAR(V_ENDDAT, 'YYYYMMDD')||' '||
V_ENDUHR||' '||
  rtrim(V_AUSSAGEW)||' '||
  rtrim(V_LANGTEXT)   thisText
        FROM AKTIV
        WHERE V_PROBLEM = p_PROBLEM
        ORDER BY Aktiv_NR;
    AKLangTextRec   AKLangTextCur%ROWTYPE;

################################### Above
BEGIN
FOR v_LoopIndex IN 1..pkgFreeText.v_NumEntries LOOP
    V_AKTIV_NR := pkgFreeText.V_AKTIV_NR_P(v_LoopIndex);
    V_PROBLEM := pkgFreeText.V_PROBLEM_P(v_LoopIndex);
    V_ENDDAT   := pkgFreeText.V_ENDDAT_P(v_LoopIndex);
    V_ENDUHR   := pkgFreeText.V_ENDUHR_P(v_LoopIndex);
    V_AUSSAGEW := pkgFreeText.V_AUSSAGEW_P(v_LoopIndex);
    V_LANGTEXT := pkgFreeText.V_LANGTEXT_P(v_LoopIndex);

SELECT PROBLEM INTO p_PROBLEM FROM PROBLEM;

########## CURSOR DECLARE should be HERE ##########

    BEGIN
     OPEN AKLangTextCur;
          LOOP
            FETCH AKLangTextCur into AKLangTextRec;
            EXIT WHEN AKLangTextCur%NOTFOUND;
            V_LONGTEXT_CUR := V_LONGTEXT_CUR ||AKLangTextRec.thisText;
         END LOOP;
     CLOSE AKLangTextCur;
    END;
  V_LONGTEXT := V_LONGTEXT || V_LONGTEXT_CUR;

END LOOP;
   V_LONGTEXT_TRIM := RTRIM(V_LONGTEXT, 2000);

Thanks a lot for help

Wendy
