concatenate a string and a sequence number

Hey guys,.

I use jdeveloper Studio Edition Version 11.1.2.1.0.

I would attribute a sequence that I have attached a string to my PK as a AP2013081000 attribute.

Could someone help how the above application can be achieved in the adf?

Here are the trigger and how could I use it to record in my attribute?

create or replace

LEARNER_TRG RELAXATION

INSERT BEFORE ON THE LEARNER

FOR EACH LINE

BEGIN

< < COLUMN_SEQUENCES > >

BEGIN

IF: NEW. STUDENTNO IS NULL OR: NEW. STUDENTNO < 0 THEN

SELECT TO_CHAR ("AP": to_char (sysdate, 'YYYYMM') |) LEARNER_SEQ. NEXTVAL) IN: NEW. STUDENTNO FROM DUAL;

END IF;

END COLUMN_SEQUENCES;

END;

I used the DBSequence data type

only for the

LEARNER_TRG RELAXATION

INSERT BEFORE ON THE LEARNER

FOR EACH LINE

BEGIN

< < COLUMN_SEQUENCES > >

BEGIN

IF: NEW. STUDENTNO IS NULL OR: NEW. STUDENTNO < 0 THEN

SELECT to_char (sysdate, 'YYYYMM') | LEARNER_SEQ. NEXTVAL INTO: NEW. STUDENTNO FROM DUAL;

END IF;

END COLUMN_SEQUENCES;

END;

Kind regards

You should be able to use the groovy for that approach. In this case you needn't pl/sql. Binary decompilation ADF: Groovy expression for assignment DB Sequence value for an attribute of type String should help you get started.

    How to set the default value of the attribute with a sequence number? Is it possible to add a string to seq.no. like abc0001?

    Concerning

    For the date, you can use groovy expression adf.currentDate to set the current date. reference http://adfgouravtkiet.blogspot.in/2012/11/how-to-set-default-values-for-entity.html

    You already have ways to use the sequence.

    How do you add a new value in the form. You're creating a new line of your page (user interface) and by engaging with validation operation? Unless you commit you will not be able to see anything in the table.

  • Insert/update of the XML help merge and to generate the sequence number

    Hello

    I'm working on Oracle 11 g.

    I have a doubt with loading XML.
    I get an xml and I need to insert or update data in a table. What I can accomplish by using the MERGE statement.
    But there is a column in A table, I need to fill with a sequence number, based on the data sent in the xml file.
    The XML does not send the data in this column.
    And I have to make sure that sequence is created according to the order in which the records are present in xml.
    For example the MERGER is insert five rows and update two lines and insert again 3 rows of xml in table A. The sequence number must be created in the same order for the column in the table.
    Also for every new XML, the sequence starts with 1 and ends with the number of records in the xml file. I can't create a sequence and use the seq.nextval.

    Please let me know, there is a way to achieve this.

    Thank you!

    Hello

    As a result of your previous thread: {: identifier of the thread = 2403469}

    You can use the clause for ORDINALITE in XMLTable to generate the necessary sequence:

    MERGE INTO target_table t
    USING (
      SELECT x.seq_num, x.pk_id, x.col1, x.col2, ...
      FROM XMLTable(
             '/root/record'
             passing my_xml_doc
             columns seq_num FOR ORDINALITY
                   , pk_id   number       path 'ID'
                   , col1    varchar2(30) path 'COL1'
                   , col2    varchar2(30) path 'COL2'
                   , ...
           ) x
    ) src
    ON ( t.pk_id = src.pk_id )
    WHEN MATCHED THEN UPDATE
     SET t.seq_num = src.seq_num
       , t.col1 = src.col1

  • Comparison between a static value type String and a type perhaps unrelated number

    Well I have another question of my book of text... so far I typed in exactly how they ask me to and even followed some screenshots of examples of theres. All me looks good, but of course, I'm the only one with an untrained eye.

    When I run this film I get a compiler error of: 1176 20 comparison between a static value type String and a type perhaps unrelated to line number

    Here is my code

    import flash.events.MouseEvent;

    Stop();
    var numberOfCookies:Number = 0;
    startBtn.addEventListener (MouseEvent.CLICK, getCookies);
    function getCookies(event:MouseEvent)
    {
    numberOfCookies = (Math.floor (Math.random () * (10)) + 1);
    var n: Number = 0;
    While (n < numberOfCookies)
    {
    var cookieInstance:cookieMC = new cookieMC;
    addChild (cookieInstance) .x = (Math.random () * 200) + 20, (cookieInstance) there (Math.random () * 150) = + 220;
    n ++ ;
    }
    }
    goBtn.addEventListener (MouseEvent.CLICK, checkNumberTyped);
    function checkNumberTyped(event:MouseEvent)
    {
    If (checkBox.text == numberOfCookies) //this is the line 20
    {
    gotoAndPlay (2);
    }
    on the other
    {
    gotoAndPlay (3);
    }
    }

    The error indicates well enough the problem... the compiler doesn't like to compare different types of things.  In your case, a type is a string, and the other type is a number.  If you need to force one of them to become another type, and you can go either way...

    If (checkBox.text is String (numberOfCookies))

    OR

    If ((checkBox.text) Number is numberOfCookies)

    Hello

    You want something like this:

    WITH       got_grp     AS
    (

         ,     seq_num          -- SEQUENCE is not a good column name
         ,     seq_num - ROW_NUMBER () OVER ( PARTITION BY  lot
                                                      ORDER BY      seq_num
                                          ) AS grp
         FROM    pins
    --     WHERE     ...     -- any filtering goes here

    ,            grp
    ORDER BY  lot
    ,            min_seq_num
    ;
    

    If I understand the probem, you want to GROUP BY, but many does not define groups by itself: each contiguous set of seq_nums in a batch is a separate group. In each of these groups, the difference between seq_num and a meter which reflects the order of seq_num generated in the query (using ROW_NUMBER) will be constant.

    This assumes that seq_num is an integer, and this (lot, seq_num) is unique.
    If this is not the case, the above query will have a small adjustment.

    If you want to display the INSERT statements for your sample data, then I could test this.

  • Motherboard model H535 failure - the type of machine and the serial number invalid after replacement

    Does anyone know how to set the new Type of Machine and the serial number after a motherboard for a replacement model H535?

    The motherboard has recently failed on my model H535 (7 months after the expiration of the warranty - thanks, Lenovo). No local garage would agree to replace due to its nature of owners (thanks, Lenovo). I spent about four hours on the phone being bounced into back-and-forth between the many support staff (usually combined) Lenovo in sales, technical support, support of parts of IBM and various other departments (thanks, Lenovo), which one has suggested that I might have to try to find a motherboard on Ebay or Amazon for my computer in less-than-2-year-old. However, I finally get to someone at Lenovo, which has been able to sell a motherboard - for 2/3 of the cost of the original computer.

    Now, I installed the motherboard, and it works. However, during each boot, I get a POST with two beeps error which reads as follows:

    00CE error: Machine Type and serial number is INVALID

    Start of manufacturing sequence is taken if no selection is made

    I presume that the BIOS on the new motherboard must be programmed with the right Type of Machine and the serial number of my computer. I've read various things on the Internet about what to do, as updating the BIOS (I can not even find a BIOS under "downloads" of support for the H535 - thanks, Lenovo model), using WinPhlash (I apparently need one kind of BIOS ROM file to make it work, I don't have), getting a Lenovo hardware maintenance disk for my model (which apparently isn't available for other special people only me - thanks Lenovo), etc.

    The waiting time for Lenovo support are ridiculously long, and almost every customer support person is ridiculously uninformed on the difference between one of their computer models, and even less their motherboards (thanks, Lenovo). I am amazed and extremely frustrated. It shouldn't be rocket science.

    On a side note, I initially bought the computer from Staples with a credit card with extended warranty protection, which means I can get a refund for repair. Although the motherboard came with a packing list, no Bill has been provided by Lenovo, and I couldn't make them send one - or maybe even with success to explain what a Bill is (thanks, Lenovo).

    Well, Lenovo support was useless, and any alleged authorized suppliers were in fact still suppliers or could help with my problem. But I was finally able to fix it myself. Once I found the right piece of software, it has been fixed in less than a minute.

    My BIOS is by American Megatrends, and I discovered that they have a set of utilities that includes a called AMIDEDOS. It is intended for manufacturers to be able to change the strings of text stored in the BIOS for things like the manufacturer, product name, Version, number series, UUID, SKU number, family, etc., that is what I had to do. It is not intended for use by consumers, but it's there.

    When I ran the "DMIEdit.exe" program AMIDEDOS (clicked and ran as administrator from 10 Windows) and click on "System information" from the list, I saw "Product Name | STRING | Invalid' and ' serial number | STRING | NOT VALID ". The other fields appeared to have valid entries. I double-clicked on the fields valid and changed their "H535 model" and the serial number of my computer, respectively and then clicked on "Update all" at the top.

    Much to my surprise, he reported that he had successfully registered the new information. And, perhaps even more surprising is the fact that, when I rebooted, the double beep and the warning about the type of computer not valid and serial number have disappeared. In addition, the BIOS showed I had entered the new values, and the 'Manufacturing Boot Sequence' option (I understand can be much slower than a normal boot) had disappeared.

    Again, I'm a little surprised simple it was actually solve the problem once I got the correct software, or Lenovo part nor American Megatrends apparently offers to the owners, and it took hours and hours of research and research to understand. Use this information at your own risk, however, as playing with BIOS apparently can lead to problems not easily solved. That said, the modification of these text strings seems relatively safe.

    I will mention that I also ended up changing the method of "LEGACY" to "UEFI" boot in the BIOS after noticing that the selection.

    Oracle 11.1

    How can given this structure and data, I generate sequence at the end of each line numbers? Basically, the sequence number (x.y.z) is such that x (1.n) is awarded for each unique value in file_no. In each x, y (1.n) is assigned for each unique value of batch_no. Within each y, z (1.n) is assigned for all records of this batch. Sample data shows only dt but all sequences must reset and start over when dt changes.

    I tried using row_number() over (partition by dt, file_no) and such but nothing quite gives me what I'm looking for.

    Help? Thank you

    Hello

    If you look at my CREATE TABLE, the ID column is a primary key and represents the order of the data in the file.

    Done batch_no = 100 come before or after 101?  Batch_no = 100 a ID so much until after the id for batch_no = 101.

    Good point, but that won't happen because of the way the 'record' is generated. All batch_nos will be contiguous. So if batch_no 100 comes earlier in the file as 101, it should get some 2nd highest sequence number. Otherwise, lower. Basically, the 2nd part of the sequence must simialar logical number to the 3rd party (i.e. order by id) but that messes things. Still struggle with it. Any help appreciated.

    I think I understand.  You say that, because of the way that the ID is issued, it wouldn't matter if you used the highest id of the batch_no, or the lowest id, or the average, or if you chose one at random; you would get the correct order in all cases.

    The following query uses the id low in the order file_no and batch_nos.

    (

    SELECT id, dt, file_no, batch_no, data

    "ORDER BY file_no" and "ORDER BY batch_no", she uses

    "ORDER BY min_id_file_no" and "ORDER BY min_id_batch_no".  These values are calculated in the subquery, got_min_ids.
