Need Help Creating Manual Tabular Form

Question

Hello,
I am trying to use Denes Kubicek example. [http://htmldb.oracle.com/pls/otn/f?p=31517:170:370485826041084::NO]
I am not getting any errors; however, my table is not getting updated.
Updatable Query:
SELECT DISTINCT
apex_item.HIDDEN(1,PE_BID) PE_BID,
apex_item.HIDDEN(2,PE_TERM_CODE) PE_TERM_CODE,
apex_item.HIDDEN(3,PE_CRN) PE_CRN,
apex_item.HIDDEN(4,PE_INSTRUCTOR_ID) PE_INSTRUCTOR_ID,
PE_BID PE_BID_DISPLAY,
SUBSTR(PE_STUDENT_NAME, (INSTR(PE_STUDENT_NAME, ',') + 1),77)|| ' ' ||
SUBSTR(PE_STUDENT_NAME, 1,(INSTR(PE_STUDENT_NAME, ',') - 1)) Stu_Name,
PE_ATH_CODES Sport,
PE_CRN PE_CRN_DISPLAY,
PE_CRSE_SUBJECT || ' ' || PE_CRSE_NUMBER || '.'||PE_CRSE_SECTION COURSE,
apex_item.SELECT_LIST(5,PE_SATTEND,'YES;YES,NO;NO') PE_SATTEND,
apex_item.SELECT_LIST(6,PE_SPERFORM,'YES;YES,NO;NO') PE_SPERFORM,
apex_item.SELECT_LIST(7,PE_MAKE_APPT,'YES;YES,NO;NO') PE_MAKE_APPT,
apex_item.TEXTAREA(8,PE_COMMENTS,3,30) PE_COMMENTS,
apex_item.TEXT(9,PE_ACTIVITY_DATE,15) PE_ACTIVITY_DATE
FROM PC_ST_TB_INSTR_ATHL_PR_ENTRY
WHERE PE_TERM_CODE = :P4_TERM
AND (PE_INSTRUCTOR_ID = :P4_DISPLAY_INSTRUCTOR_ID
OR PE_INSTRUCTOR_ID = :P4_DISPLAY_INSTRUCTOR_ID2)Page Process:
DECLARE
v_updatecount NUMBER := 0;
BEGIN
FOR i IN 1 .. apex_application.g_f01.COUNT
LOOP
UPDATE PC_ST_TB_INSTR_ATHL_PR_ENTRY
SET pe_sattend = apex_application.g_f05(i),
pe_sperform = apex_application.g_f06(i),
pe_make_appt = apex_application.g_f07(i),
pe_comments = apex_application.g_f08(i),
pe_activity_date = apex_application.g_f09(i)
WHERE pe_instructor_id = apex_application.g_f04(i)
AND pe_bid = apex_application.g_f01(i)
AND pe_term_code = apex_application.g_f02(i)
AND pe_crn = apex_application.g_f03(i);
v_updatecount := v_updatecount + 1;
END LOOP;
:P4_DISPLAY_COUNT := v_updatecount;
END;I can't use the wizard because it appears to only allow for 2 primary keys. My table has 4.

Hi,
The first thing to do is concatenate the HIDDEN items in front of a displayed item:
SELECT DISTINCT
apex_item.HIDDEN(1,PE_BID) || apex_item.HIDDEN(2,PE_TERM_CODE) || apex_item.HIDDEN(3,PE_CRN) || apex_item.HIDDEN(4,PE_INSTRUCTOR_ID) || PE_BID PE_BID_DISPLAY,
..etc..That way, you don't have to worry about the first 4 columns in the report.
Then you need to double-check that the process is actually being run. Immediately after the BEGIN line, enter:
raise_application_error(apex_application.g_f01(1));When you submit the page, you should get an error showing the PE_BID value in the first row. If you don't get the error, then the process isn't being run - in which case, check the process to (A) make sure it is triggered by the Submit button and (B) is before any other sequence (especially if you have a "reset page" process). If you do get the error, but there is no value shown, then f01(1) isn't pointing to the PE_BID value - in which case, you should do a View Source on the loaded page and check for input items with a name attribute of "f01". If you get the error and the value is correct, then remove the above line and let the process run - it could be that concatenated the columns may resolve the issue. If, after all that, the process still won't save the data, let us know.
