Failed to insert a new line with a column generated sequence id

Hello

I'm trying to insert a new row in a table containing a column of sequence according to db, used as the primary key.

Here is the code for the custom method of the corresponding AM I use to insert the new line:

Line row2 = getCaAppointments1 () .createRow ();
row2.SetAttribute ("Member ID", Member ID);
row2.SetAttribute ("Status", "Planned");
row2.SetAttribute ("CreatedBy", coachId);
row2.SetAttribute ("CreationDate", date);
AppointmentId will be generated by the sequence
DBSequence newId = row2.getAttribute("AppointmentId") (DBSequence);
SequenceImpl s = new SequenceImpl ("XX_CA_APPOINTMENT_ID", getDBTransaction());
Long next = newId.getSequenceNumber () .longValue ();
System.out.println ("Got sequence as id:" + newId);
row2.SetAttribute ("AppointmentId", newId);
row2.SetAttribute ("CoachId", coachId);
row2.SetAttribute ("Type", "0");
row2.SetAttribute ("AppointmentNumber", 0);
row2.SetAttribute ("PlannedDate", Department of justice);
getCaAppointments1 (.insertRow (row2));

I put the attribute EO 'AppointmentId' to use a DBSequence. I tried different combinations to get the sequence Id and insert a line. Nothing worked well and I'm unable to insert a new line.

If I avoid using the attribute 'AppointmentId' and that you try to insert a row, it will fail with the error below:

ORA-01400: cannot insert NULL into ('APPS'. "" "" XX_CA_APPOINTMENTS '. "" APPOINTMENT_ID") ORA-06512: at line 1

Tried to insert the new row using BCTester but I am struck by the same error it (I was unable to change the value of the "AppointmentId" column when inserting the line because this column is read-only and it showed as - 2 value).

I guess, since the attribute of column/is already marked to use a DBSequence, the value should be assigned by default and I shouldn't hit "cannot insert the value NULL to the column.
Did I miss something necessary to trigger the sequence to automatically generate new Id and assign it to the new line before it is created?

Please let me know the fix.

Thanks in advance

Hello

Oracle changes this behavior each version, so I hope that its still OK.
If you have a trigger on the table that inserts the value of the id if none is preset, then mark it as DBSequence, or be it the number.

Now for your entity, just generate the impl class and override the method create, kind of old school, I know, but it never fails.
In the create just add the code to your sequence you had:

SequenceImpl seqImpl = new SequenceImpl("", thisTransaction);
Number idValue= s.getSequenceNumber();
setAttribute("Id", idValue);

  • Replace the carriage return or new line with a table space

    Hello

    I want to replace the carriage return or new line with space in my column of the database.

    To do this, I'm using this query:

    Select replace (replace (Comments, chr (10),' '), Chr (13),' ') OF Comments_Master

    Comments_Master is the name of the table and comments is column that contains carriage return or new line.

    But this query works as expected.

    Once I run this query and run the query again "select * FROM Comments_Master", transport return and new line still exist.

    Please let me know what is wrong with this query?

    You write that data back you? This example shows that your sql should work. I thinnk the query that you just described is the updated one below.

    create table blah (text varchar2 (100));

    insert into bla values (' it's multi)

    line of text ");"

    Select * from blah.

    Select replace (replace (text, chr (10),' '), Chr (13),' ') of bla.

    Update text bla = replace (replace (text, chr (10),' '), Chr (13),' ');

    Select * from blah.

  • ExceltoCI to insert a new line of effdt by calling JOB_DATA

    Hi all

    We strive to use ExceltoCI to insert a new line of effdt in the JOB_DATA component. But it does not work when the BU evolves. I believe that it is caused by, to assign DRANK before the other active SETID field as service, places, jobcodes, etc. But unfortunately, in the JOB file/table Business Unit is after DEPTID, LOCATION, JOBCODE field that causes the allocation of the value of the BU arrived after the assignment of DEPTID and LOCATION ect. So I'm getting invalid departments, locations, jobcodes error. Because I'm not aware of a way to change the sequence of loading using ExceltoCI.

    Any idea on how I can accomplish this for the use of ExceltoCIs or it is impossible? Thank you much in advance.
    PS I know that it is very simple to use AE + CI to do this.

    This seems to be a known issue, see this doc

    E here: PT8.4x - ExcelToCI fails if the properties are not subject in proper order [649358.1 ID]

    I'm a little surprised by the workaround provided in this doc for that matter...

  • CP5 narrow legends: insert a new line between existing lines

    In the Notes slide - closed captioning - 'Folienaudio' / 'Bilduntertitel' (narrow legends) is already there lines 1, 2, 3 and 4. I need to insert a new line between lines 3 and 4, but the + always opens a new line to the 2nd line.

    Is there a way to overcome this problem?

    Hello

    This can be done safely by the tab this subtitle in the audio slide dialog box.

    1. call the audio slide dialog box (shortcut: F5)

    2. go to the tab captions

    3. play audio

    4 stop the audio to the point where you need to add subtitles

    5. click on the button '+' to add captioning to the place you need.

    6. click on 'Save' to save the changes.

    This will save time.

    Rick: It could probably also completely accomplish the CC dialog box. I saw the recent problems reported with operation directly from this dialog box in CP5, so I offered to beginning of slide Notes.

    Ashwin: I do not see problems here Rick...

  • ADF: how to insert the character of new line in the column of VO?

    Hello world

    IM using Jdev 11 G.
    I have a VO with 5 columns appear on the page of the ADF. (VO a total 8 columns)
    column 1 is the combination of 3 columns. I concatenated 3 columns and add the new line character after each column Chr (13).
    VO query works very well as a toad. the columnn displays each column value concatenated after a newline character, but the same query does not work in the ADF.
    The column that is the concatenation of the 3 columns and should display with the new line character does not display the new line character its just concatenation of the 3 values and display on the page.

    Wat could be the solution for this in the ADF?

    Thank you.

    Column does not have the property to escape. It is part of the output text.

    Something like

    Hello

    This is called the aggregation of the chain and this page:
    http://www.Oracle-base.com/articles/10G/StringAggregationTechniques.php
    shows several ways to do so.

    Which way is best for you? It depends on your version of Oracle and exactly to your needs (for example, if the items in the list should be in order or not).
    If you use Oracle 11.2, then new LISTAGG built-in function is probably what you want.

  • Adding new line with image field

    Hi all!

    I have trouble getting my image fields to work the way I need them for.  (Example attached).  What I need is for the user (who intends to use Reader) to enter text information, then enter a room, or a diagram and then, if necessary add another set of texts and the room.  I need each row to add and remove as well independently (similar to my line of text is already configured).  I tried to have a table set in place and repeat as the table, but the field of the Image will not work properly and shrinks to a small size.  I really want the user to be able to determine the size.

    Is it possible that I can do this?

    With the change of structure of the table has been introduced a new subform (SystemDiagram). Therefore, update your expressions in order to integrate this new structure. So now, the click event of the button ResetForm code should look like this:

    Content.SystemDiagram.ImageDiagram.DiagramSub.Diagram.rawValue = null;
    Content.SystemDiagram.ImageDiagram.DiagramSub.Diagram.h = "0,6813 in";
