Data is not displayed for some ID from the procedure in oracle

Question

I have a stored procedure which brings all the data created by a particular users. So if a user with name A has created 100 records and when I run this procedure it should bring 100 records.

Currently it is not bringing all those 100 records, some of them are missing and I am unable to find out why it's like that.

Below is my stored procedure.

create or replace PROCEDURE CHANGEREQUESTS_CREATED_GETLIST
(
  P_USERNAME in CHANGEREQUESTS.CREATEDBY%type
, P_JOBID IN CLOB--VARCHAR2
, P_PAGENO IN NUMBER
, P_PAGESIZE IN NUMBER
, TOTALCOUNT OUT NUMBER
, OUTPUTTABLE OUT SYS_REFCURSOR
) AS 

  START_RECORD_NO NUMBER := 1;
  END_RECORD_NO   NUMBER := 10;
BEGIN

  IF P_PAGENO IS NOT NULL AND P_PAGESIZE IS NOT NULL THEN
    START_RECORD_NO := ((P_PAGENO -1) * P_PAGESIZE) +1;
    END_RECORD_NO := P_PAGESIZE * P_PAGENO;
  END IF;
    
  --open TOTALCOUNT for
  SELECT COUNT(*) INTO TOTALCOUNT 
  FROM  
      CHANGEREQUESTS CR
  where
   EXISTS ( SELECT * FROM THE ( SELECT CAST( STR2TBL( P_JOBID ) AS MYTABLETYPE ) FROM DUAL ) TT WHERE TT.COLUMN_VALUE = CR.JOBID )
      --CR.JOBID in (select REGEXP_SUBSTR(P_JOBID,'[^,]+', 1, level) from DUAL connect by REGEXP_SUBSTR(P_JOBID, '[^,]+', 1, level) is not null)
      and CREATEDBY = P_USERNAME
      and JOBID > 0;
          
  OPEN OUTPUTTABLE FOR

        --ORDER BY CR.CHANGEREQUESTID DESC
      )
  WHERE ROWNO >= START_RECORD_NO AND ROWNO <= END_RECORD_NO;

UPDATE

So basically my Oracle version is:- 18.3

Also,

The above procedure consists of 3 tables in which main columns are CHANGETYPEID, CHANGECATEGORYID They have joined to bring the data.

So my main table is CHANGEREQUESTS where records are been fetched from joining the ID's of other two tables.

For ex:-

CREATE TABLE CHANGEREQUESTS ( CHANGEREQUESTID, CHANGETYPEID, JOBID ) AS 
SELECT 7835,  4, 42234 FROM DUAL UNION ALL
SELECT 7834, 22, 42233 FROM DUAL UNION ALL
SELECT 7833,  8, 42242 FROM DUAL;

CREATE TABLE CHANGETYPES (CHANGETYPEID, CHANGETYPE, CHANGECATEGORYID, ISACTIVE) AS
SELECT  8, 'Change in media type (OFC/MW)', 1, 1 FROM DUAL UNION ALL
SELECT 22, 'RF site deletion',              1, 1 FROM DUAL;

CREATE TABLE CHANGECATEGORIES ( CHANGECATEGORYID, CATEGORY, ISACTIVE ) AS
SELECT 3, 'OSP Engineering', 1 FROM DUAL UNION ALL
SELECT 2, 'Wireline',        1 FROM DUAL UNION ALL
SELECT 1, 'Wireless',        1 FROM DUAL;

Answer 1

You can simplify your procedure a lot by:

• testing if the jobid is a substring of the p_jobid parameter; and
• using OFFSET m ROWS FETCH NEXT n ROWS ONLY syntax.

create or replace PROCEDURE CHANGEREQUESTS_CREATED_GETLIST
(
  P_USERNAME IN CHANGEREQUESTS.CREATEDBY%type
, P_JOBID    IN CLOB--VARCHAR2
, P_PAGENO   IN NUMBER
, P_PAGESIZE IN NUMBER
, TOTALCOUNT OUT NUMBER
, OUTPUTTABLE OUT SYS_REFCURSOR
)
AS
  v_size  NUMBER := COALESCE( p_pagesize, 10 );
  v_start NUMBER := COALESCE( p_pageno - 1, 0 ) * v_size;
BEGIN
  SELECT COUNT(*) INTO TOTALCOUNT 
  FROM   CHANGEREQUESTS CR
  WHERE  ',' || p_jobid || ',' LIKE '%,' || jobid || ',%'
  AND    CREATEDBY = P_USERNAME
  AND    JOBID > 0;

  OPEN OUTPUTTABLE FOR 
  SELECT CR.CHANGEREQUESTID
        ,CT.CHANGETYPE
        ,CR.JOBID
  FROM   CHANGEREQUESTS CR
         INNER JOIN CHANGETYPES CT
           ON ( CR.CHANGETYPEID = CT.CHANGETYPEID )
         INNER JOIN CHANGECATEGORIES CC
           ON ( CC.CHANGECATEGORYID = CT.CHANGECATEGORYID )
  WHERE  ',' || p_jobid || ',' LIKE '%,' || jobid || ',%'
  AND    CREATEDBY = P_USERNAME
  AND    JOBID > 0
  ORDER BY CR.CHANGEREQUESTID DESC
  OFFSET v_start ROWS
  FETCH NEXT v_size ROWS ONLY;
END CHANGEREQUESTS_CREATED_GETLIST;
/

Which, for the sample data:

CREATE TABLE CHANGEREQUESTS ( CHANGEREQUESTID, CHANGETYPEID, JOBID, CREATEDBY ) AS 
SELECT 7835,  4, 42234, 'user1' FROM DUAL UNION ALL
SELECT 7834, 22, 42233, 'user1' FROM DUAL UNION ALL
SELECT 7833,  8, 42242, 'user1' FROM DUAL UNION ALL
SELECT LEVEL,
       DECODE( MOD( LEVEL, 3), 0, 4, 1, 22, 8 ),
       99999,
       'user1'
FROM   DUAL
CONNECT BY LEVEL <= 40;

CREATE TABLE CHANGETYPES (CHANGETYPEID, CHANGETYPE, CHANGECATEGORYID, ISACTIVE) AS
SELECT  4, 'Random Type',                   1, 1 FROM DUAL UNION ALL
SELECT  8, 'Change in media type (OFC/MW)', 1, 1 FROM DUAL UNION ALL
SELECT 22, 'RF site deletion',              1, 1 FROM DUAL;

CREATE TABLE CHANGECATEGORIES ( CHANGECATEGORYID, CATEGORY, ISACTIVE ) AS
SELECT 3, 'OSP Engineering', 1 FROM DUAL UNION ALL
SELECT 2, 'Wireline',        1 FROM DUAL UNION ALL
SELECT 1, 'Wireless',        1 FROM DUAL;

Then:

DECLARE
  v_pgsz NUMBER := 20;
BEGIN
  FOR v_pgno IN 1 .. 3 LOOP
    DECLARE
      v_cur  SYS_REFCURSOR;
      v_size NUMBER;
      v_crid CHANGEREQUESTS.CHANGEREQUESTID%TYPE;
      v_ctyp CHANGETYPES.CHANGETYPE%TYPE;
      v_jid  CHANGEREQUESTS.JOBID%TYPE;
    BEGIN
      CHANGEREQUESTS_CREATED_GETLIST( 'user1', '42234,99999', v_pgno, v_pgsz, v_size, v_cur );
      DBMS_OUTPUT.PUT_LINE( 'Page:' || v_pgno || ' (Total: ' || v_size || ' rows)' );
      LOOP
        FETCH v_cur INTO v_crid, v_ctyp, v_jid;
        EXIT WHEN v_cur%NOTFOUND;
        DBMS_OUTPUT.PUT_LINE(
          LPAD( v_crid,  4, ' ' ) || ' | ' ||
          RPAD( v_ctyp, 30, ' ' ) || ' | ' ||
          LPAD( v_jid,   4, ' ' )
        );
      END LOOP;
      CLOSE v_cur;
    END;
  END LOOP;
END;
/

Outputs:
