A better way to treat the form as a table with the variable column type?

I wanted to make a column to return according to the status of a flag column as readonly. I have a column defined as follows in the report query.

Decode (sys_flag, 'Y', APEX_ITEM. DISPLAY_AND_SAVE 3, TYPE_CODE, APEX_ITEM. SELECT_LIST_FROM_LOV (3, TYPE_CODE, 'LOV_TYPE_CODE_LOV')) AS TYPE_CODE

To get the SRM process noting that column, I had to put this 'band of HTML code' to 'No', then the column attributes, I put:
"Expression HTML" to "#TYPE_CODE #
' Display under "to"text display (saves the State).

And then it took me to get new lines of work:
"Default of Type" to "Expression of PL/SQL.
'Default' to APEX_ITEM. SELECT_LIST_FROM_LOV (3, NVL(:P18_TYPE_CODE,'LOV_TYPE'), NULL, 'LOV_TYPE_CODE_LOV', ' NO')

This makes large, however submit that it seems that the checksum of line used by MRU included the raw HTML generated by the APEX_ITEM package and not just the value of the column. I worked around this by including an element hidden checksum and creating a process that replaces the checksum generated automatically with my custom.

Is there a better way to intercept this checksum, preferably before it is rendered on the page? I now hide the sum of hidden HTML control in the output HTML of another column, so it's a bit ugly. If not, is there an easier way to achieve what I'm looking for? I tried several combinations, and it seems to work better. It's just a shame there's no way to have a standard hidden column included in the SRM process.

Hello

I tried different possibilities and seems to run the following:

Create a report questioning in NORMAL SQL function to help:

SELECT
APEX_ITEM.HIDDEN(1,EMPNO) || APEX_ITEM.TEXT(2,ENAME) ename,
CASE WHEN DEPTNO = 10 THEN
 APEX_ITEM.HIDDEN(3, SAL) || SAL
ELSE
 APEX_ITEM.TEXT(3, SAL)
END SAL,
EMPNO,
DEPTNO || APEX_ITEM.MD5_CHECKSUM(ENAME, SAL) DETPNO
FROM EMP

Do not specify something special for column definitions.

Create a button that submits the page.

Create a PL/SQL process that runs "On submit - after calculations" and Validations, triggered by this button and using the following code:

BEGIN
APEX_ITEM.MULTI_ROW_UPDATE('#OWNER#:EMP:EMPNO,1:,|ENAME,2:SAL,3');
END;

I've done here: http://htmldb.oracle.com/pls/otn/f?p=55041:35

Any element with the value of DEPTNO 10 has the value SAL, read-only, as otherwise it's editable. This is done by creating a hidden input field for the actual value, followed by the text version OR by creating a single entry field. This ensures that we have the correct number of SAL elements on the page.

APEX_ITEM. MULTI_ROW_UPDATE is the "manual" version of the MRU that you would normally get with a form of table and works for above normal as sql based query reports. The format of this very strict is that you must always allow for two primary keys. See the text of presentation here: http://download.oracle.com/docs/cd/B28359_01/appdev.111/b32258/api.htm#CHDFDACC

  • Looking for a better way to count the responses to the survey questions

    Hello all - I have created a survey for a site and now want to display the results to the admins of the site. I am trying to display the countdown - the number of times that a question has been answered in a certain way. I realize that I may need to build the investigation itself differently and how it stores data, but here is how it goes far.

    There are 10 questions, each with 4 options of radio button groups. The database table contains a column for each issue and stores the value of the selected option button. So it's pretty simple.

    Now on the results page, that it's the only way I can think to do, but there must be a better way. For each answer, I create a Recordset filtered on the issue and the value option, then display the total number of records. Which works great, but count each option, which means that 40 recordsets on the page - al simply determine "how many times was the Question 1, Option was selected and how many times has the Question 1, selected Option B and so on.»

    The only other thing I can think it maybe is a better way to count the occurrences of these values in the table is with PHP or in the SQL itself.  Or, perhaps, if the values themselves are entirely digital and follow a kind of model I can use a solution of math.

    Thoughts, solutions, and ideas are welcome!  Thank you.

    Your problem is a bad design. You should have a separate line for each answer, not to separate the columns. It also makes the very rigid investigation. A simple design would include a few tables - a master of the investigation that stores the questions and response table that contains a foreign key to the question number in the master, the answer, as well as any other details you need to capture. You might get more elaborate, but it's essential. Your result page and then just be a single recordset with a simple query with a group by clause.

    I urge you to review this before going any further.

    Hello

    The problem is that you to act as a Cartesian product with all the tables (you will get: S01 * S02 * S08 * S09 lines!) Is it really what you want?
    I don't think...

    Wharton, you can do (with no Cartesian product) is:

    CURSOR c_sortest_SAT_scores(p_pidm IN saturn.sortest.sortest_pidm%TYPE,
p_term in saradap.saradap_term_code_entry%TYPE)
IS
SELECT sortest_pidm pidm, sortest_tesc_code tesc_code,
       sortest_test_score score
  FROM sortest
 WHERE (sortest_tesc_code, sortest_test_score) IN (
          SELECT   sortest_tesc_code, MAX (sortest_test_score)
              FROM sortest
             WHERE sortest_tesc_code IN ('S01', 'S02', 'S07', 'S08', 'S09')
               AND sortest_pidm = :p_pidm
               AND sortest_term_code_entry = :p_term
          GROUP BY sortest_tesc_code)
   AND sortest_pidm = :p_pidm
   AND sortest_term_code_entry = :p_term

    However you absolutely need a Cartesian product, you can do:

    WITH allrows AS
     (SELECT sortest_pidm pidm, sortest_tesc_code tesc_code,
             sortest_test_score score
        FROM sortest
       WHERE (sortest_tesc_code, sortest_test_score) IN (
                SELECT   sortest_tesc_code, MAX (sortest_test_score)
                    FROM sortest
                   WHERE sortest_tesc_code IN
                                          ('S01', 'S02', 'S07', 'S08', 'S09')

                     AND sortest_term_code_entry = :p_term
                GROUP BY sortest_tesc_code)
         AND sortest_pidm = :p_pidm

  • Form on a Table with report - Auto number

    Hello

    Scenario:
    I want to create 'Form on a table with report' which would allow my users add records...

    Steps and questions
    I have created a table with a field named "TRACKING_NO" as a type of automatic numbering in MS Access and there is a primary key... I intended to use it to link the report to the form
    When I downloaded the array to Oracle, it changed the varchar2 type... can you please advice how to change back to automatic numbering...?
    and it'll work if my user adds a record to the table (using APEX built in option to create a record)...?

    Thanks in advance

    Hello
    That's what I'd do.
    1. download the MS Access table, lets call it TAB_A
    2. using SQL-workshop get the DDL (SQL statement) for this table.
    3. change names or data types as required
    4. create a new table with the DOF, lets call it TAB_O
    5 copy the contents of TAB_A to TAB_O (TAB_O IN INSERT for example (id, colx, coly) SELECT TO_NUMBER (tracking_no), col1, col2 FROM TAB_A ;))
    6. create a sequence that begins with the last PK + 1 table TAB_A
    7 Add a trigger to TAB_O to use this sequence to fill his PK

    Furthermore, work with APEX requires a good understanding of the Oracle SQL and PL/SQL, no matter what anyone says, even Oracle.

    Hello

    SQL * Plus you button the output so that each column has a fixed length, which is exactly what you don't want.

    To get around this, concatenate all your data in a column VARCHAR2 fat with delimiters.

    For example, instead of

    SELECT    empno
,       ename
,       hiredate
FROM       scott.emp
;

    Do something like

    SELECT    empno
|| ';' || ename
|| ';' || TO_CHAR (hiredate, 'DD-Mon-YYYY')
FROM       scott.emp
;

  • A better way to rearrange the sort in Pivot mode?

    Hello
    First question - is there a better way to do it?

    Background - have a simple pivot w / requirements to the Status column so that logic to not alphabetical company.
    Example, # Service req with status should be listed as affected, accepted, completed, closed, re-assigned.

    My solution has been to create a column iin table view, use a CASE to say one time statement accepted = 1, etc.. I then sorted CSA, hidden column in a table view and then rotate view I added the status column and hid the new CASE column. I get the results that I expected, but I was wondering if there was a better way to do it?

    Thanks - years

    As far as the presentation layer is concernd (i.e., in the responses) your way is the best I can think of. The only way you can sort a list of values outside the way that the system can determine automatically (for example, in alphabetical, chronological, order numerically, etc.) is to create your own definition. Without human intervention or custom rules, there is no way any system know that 'C' must come before the "S" (as in "Assigned" and "Accepted" or "O" should come before the 'L' as in 'Complete' and 'Closed').

    Because the system knows how to order numbers (e.g., 1,2,3, etc.), it makes sense to create your 'rule' (using your CASE statement) to assign each level of the State to 'correct' number in the sequence.

    That's what I'd do. The only addition I can add is that you can do to the RPD by adding a column 'command' to your table LOVs and expose that as a column in the presentation layer. Then you can use this column in sort order.

  • Best way to reach the 2 columns of table A of the same column in the Table B?

    Hello

    It is a simplified example of the query, I am writing.

    I have two tables - PIPELINE (which includes the CREDIT_RECEIVER and CREATOR columns) and EMPLOYEES (including E-MAIL and LOB columns).

    I want to write a query that joins the PIPELINE. CREDIT_RECEIVER with EMPLOYEES. E-MAIL to return the LOB as 'CREDIT_RECEIVER_LOB '.

    I also want this query to join PIPELINE. CREATOR of EMPLOYEES. E-MAIL to return the LOB as 'CREATOR_LOB '.

    Currently, I do a left outer join on EMPLOYEES. EMAIL = PIPELINE. CREDIT_RECEIVER to get the "CREDIT_RECEIVER_LOB" and by calling a function GET_LOB (PIPELINE. CREATOR) (as defined below) to get the "CREATOR_LOB".

    Query:

    Select PIPELINE.ID as ID,

    PIPELINE. CREDIT_RECEIVER as CREDIT_RECEIVER,

    PIPELINE. CREATOR as a CREATOR,

    EMPLOYEES. LOB as CREDIT_RECEIVER_LOB,

    GET_LOB (PIPELINE. CREATOR) as CREATOR_LOB

    PIPELINE

    JOIN EXTERNAL LEFT ON PIPELINE EMPLOYEES. CREDIT_RECEIVER = EMPLOYEES. E-mail

  • Form on a Table with report - change of the source table after created form

    Hi all

    I have a 'form on a Table' where the various fields have the "Source Type" = "column of the database. I have 2 Questions for this type of shape:

    1: in the field "Source value or expression", it is possible to change the name of the field in the Table. But I can't understand how view or even change the underlying Table (which had to be chosen at the beginning, when the form was created at the start).

    2: my question in section that relates to the first question would be, if it is possible to have multiple underlying tables in the same region. Or whether it would be necessary to create a second region or change the "Column of the database" type in a type of SQL query?

    Thank you and best regards,

    To change the table, you need to change the process of the page. A process has been generated called:

    Here, you can modify the table, but you also have to make in your shipment after processes. Who are probably named:

    If you want a form to be based on more than one table, you can create a view and base your form on this point of view instead of on the table, or you need customized treatment.

  • How to create a form on a table with 3 columns for a PK

    Hi all

    We have a table that has 3 columns that make up the primary key and I want to create a form based on this table; Let us on the 'create form Page' it is only 2 options that identifies the first and second columns of PK.

    Is there a way I could add the third column PK.

    Kind regards
    Mel

    Mel:

    I don't think you can use the form wizard to create the form for you in this case. You can create the form manually or modify the table to have a new column that will act as a substitute PK for the table. This column can be filled from a sequence and must have a Unique key limited defined against it.

    I'm not horribly v$ sqlarea. but there were some questions about the application executes a query and get
    no row is returned.

    I find the query in v$ sqlarea but I would like to know what are bind variables, but this column is null.

    This means that the query has been run with null for all bind variables?
    or bind variables not seized for any reason are any?

    v$ sql_bind_capture I bind the value of the variable

    SELECT
   a.sql_text,
   b.name,
   b.position,
   b.datatype_string,
   b.value_string
FROM

  v$sql_bind_capture b,

  v$sqlarea          a

WHERE

   b.sql_id = 'dpf3w96us2797'

AND
   b.sql_id = a.sql_id;
