Inserting rows in cursor and breaking up when effect date matches

Question

Hi
I have created a table cadreinc (empno varchar2(8), pay number(5), da number(5) , scale varchar2(11), effectdate date , flag varchar2(1)) with values as shown below.
04485816      12800     4200     09300-34800      1-Jan-2006     Y
04485816      13000     4200     09300-34800      1-Jul-2006     Y
04485816      13450     4600     09300-34800      27-Sep-2006     Y
04485816      13675     4600     09300-34800      1-Jul-2007     Y
04485816      14200     4600     09300-34800      1-Jul-2008     Y
04485816      14650     4600     09300-34800      1-Jul-2009     Y
I just want to manipulate data into another table by using this data and i want the result as
04485816 12800 4200 09300-34800 01-jan-2006
04485816 12800 4200 09300-34800 01-feb-2006
04485816      13000     4200 09300-34800 1-Jul-2006     
04485816 13000 4200 09300-34800 1-aug-2006
like data reproduced on every month and get changes in value based on the effect date.
how to write pl sql program for this??
I have tried some what like
DECLARE
EMP VARCHAR2(8);
PAY NUMBER(5);
GP NUMBER(5);
SCALE VARCHAR2(11);
INC date;
PAD VARCHAR2(11);
FL VARCHAR2(1);
CURSOR A IS SELECT EMPNO,VIPAY,GRADEPAY,VISCALE,INCDATE,FLAG FROM CADREINC;
BEGIN
<<i_loop>> FOR I IN A LOOP
INC:=I.INCDATE;
FL:='Y';
<<j_loop>> FOR K IN 1..12 LOOP
INSERT INTO CADREFIX ( EMPNO,VIPAY,GRADEPAY,VISCALE,INCDATE) VALUES
(I.EMPNO,I.VIPAY,I.GRADEPAY,I.VISCALE,I.INCDATE);
I.incdate:=LAST_DAY(I.INCDATE)+1;
EXIT j_loop WHEN pay>i.vipay and inc=i.incdate and fl='Y';
--EXIT WHEN INC='01-JUL-2010'; 
END LOOP;
-- i.INCdate:=LAST_DAY(I.INCDATE)+1;
EXIT i_loop WHEN pay>i.vipay and inc=i.incdate and fl='Y' ;
END LOOP;
COMMIT;
END;
but unable to get the desired results. The pay comes for every 12 months instead of upto effect date.
Please help.

Hi,
Welcome to the forum!
Whenever you have a problem, please post a little sample data (CREATE TABLE and INSERT statements, relevant columns only) from all tables involved.
Also post the results you want from that data, and an explanation of how you get those results from that data, with specific examples.
If you're asking about a DML statement, such as INSERT, the CREATE TABLE and INSERT statements should re-create the tables as they are before the DML, and the results will be the contents of the changed table(s) when everything is finished.
Always say which version of Oracle you're using.
See the forum FAQ {message:id=9360002}
Here's one way to do what you want in pure SQL. Since I don't have your table, I'll use scott.emp to show the way:
WITH     data_by_month     AS
     SELECT       TRUNC (hiredate, 'MONTH')     AS hiremonth
     ,       COUNT (*)                  AS cnt
     FROM       scott.emp
     GROUP BY  TRUNC (hiredate, 'MONTH')
,     got_repeat_num     AS
     SELECT     hiremonth, cnt
     ,     MONTHS_BETWEEN ( LEAD (hiremonth) OVER (ORDER BY hiremonth)
                      , hiremonth
                      )     AS repeat_num
     FROM    data_by_month
SELECT       ADD_MONTHS ( r.hiremonth
                 , c.column_value - 1
               )                 AS report_month
,       cnt
FROM          got_repeat_num  r
CROSS JOIN     TABLE ( CAST ( MULTISET ( SELECT  LEVEL
                                              FROM        dual
                           CONNECT BY     LEVEL     <= r.repeat_num
                     AS sys.odcinumberlist
                )  c
ORDER BY  report_month
;You can use a query like this in an INSERT or MERGE statement.
If you need to use PL/SQL, then you can use an INSERT or MERGE statement, with a sub-query like the one show above, in PL/SQL.
