Auto Increment of Primary Field in Table Maintainance

Hi,
We want to give an Auto increment to the Primary Key, when ever the table is updated/inserted with a new record. How to get the value updated????
For Eg,
Table ZTEST Contains MANDT, ITEM, EBELN.
It should have the values 800 001 000977
And when the next record is created, the ITEM value should be Automatically get the value 002.. and so on for every Record.
Pls do let me know if any other details is reqd.
Thanx in Advance.
Ajaz

Dear Syed,
   You can do many things in table maintenance screen like validation of some field, making some field required or displayed etc.
   For auto increment you have to use Number-Ranges. FM NUMBER_GET_NEXT is helpful in this case.
   Where to write the code??? The Function-Group you have made. There will be includes. You can easily locate the place to write these codes.
   Caution point is that if you re-generate the table maintenance then all code will be gone.

Deva.

How to get the auto increment integer primary key value of a new record

I have a DB table that has a auto increment integer primary key, if I insert a new record into it by SQL statement "INSERT INTO...", how can I get the integer primary key value of that newly created record?

Well maybe someone knows a better method, but one workaround would be to add a dummy field to your table. When a new record is inserted this dummy field will be null. Then you can select your record with SELECT keyField FROM yourTable WHERE dummyField IS NULL. Once you've got the key number, you then update the record with a non-null value in the dummyField. Bit of a bodge, but it should work...
Another alternative is, instead of using an Autonumbered key field, you could assign your own number by getting the MAX value of the existing keys (with SELECT MAX(keyField) FROM yourTable) and using that number + 1 for your new key. Might be a problem if you have lots of records and frequent deletions though.

Auto Incrementing in Text Field

I imported a tab file and one column was the city, state and zip code. For some reason, the Zip code auto increments. It just so happened that the first cell was Durham, NC 27701. All subsequent cells incremented the Zip code by one, so the second cell became Durham, NC 27702. I have tried making the column a text field, and that did not work. I do not find any formula in the field, so am at a loss as to how to prevent the auto-incrementing from hapening.

Which Vallauris is your home city? Provence, or Pyrenees?
None, Vallauris is not in Provence but in 'Provence-Alpes-Côte-d'Azur'
At this time there is a great discussion about this name.
Some wish to change it because they think that thge acronym PACA is not their cup of tea.
Given that, inhabitants of "Provence" refuse to drop "Provence",
inhabitants of "Alpes" refuse to drop "Alpes",
inhabitants of "Cote d'Azur" refuse to drop "Cote d'Azur".
My own advice is simply : don't use an acronym !
I searched heavily and din't find a Vallauris in Pyrénées.
The only town whose name approach is :
I just found :
Valaurie
Code postal: 26230
Département: Drôme
Région: Rhône-Alpes
Vallauris sits between Cannes and Antibes.

Auto Increment Sequence Custom Field

Hi All,
I was wondering if it is possible
to have a custom field defined as an auto incrementing sequence number? E.g. Let’s say I go in and create a project for the first time, this field will show the value 1. The next project I go to create, the field shows the value 2 etc. etc.
If possible, how can this be implemented using customization? Can it be done in Project Online? Any help would be greatly appreciated. thank you!

Hi JSimoni1,
You can generate a project unique ID using a webpart, even with Project Online.
Please find below the procedure in EpmExpert blog:
http://epmxperts.wordpress.com/2012/05/21/generate-unique-id-for-project-using-a-webpart/
Note that the code might need some adjustments to stick to your business need.
Hope this helps,

Creating auto increment custom metadata field in UCM

Hello,
Can anyone tell how to create a metadata Integer field with Auto Increment option?
Also while creating users, I have a custom Department field. I want this field to be displayed in my profile. How can i achieve this?
Richa

SHort of paying someone else to do the work for you I am afraid there is no shortcut.
However writing a component need not be difficult or complex if you take a sensible approach.
There are some excellent blogs out there, at least one comprehensive book and even the documentation will get you started
http://download.oracle.com/docs/cd/E10316_01/cs/cs_doc_10/documentation/developer/sdk_getting_started_10en.pdf
I recommend you get Bex's book and you should be able to get a new component like this up and running in a day or two.

Populating Quantity fields in Table Maintainance generator Events.

Hi all,
I have a custom table, in that i have to check the material number and the quantity of the previously present entries and current entry which i am adding in the before save event.
However in the total table.... The value of material is getting populated correctly but the value of the quantity is not the actual one which i have entered, It is taking the value 0.00 at runtime.
Please suggest me the approach when we have to deal with the Quantity fields in the table events.
Thanks in advance for your help.
Regards,
Anuja

Hi,
The reference for the Quantity field is provided in the Custom table. However the value of the Quantity is taken as 0.00 at run time.
Please refer to the below code.
LOOP AT total.
    IF <action> EQ space.
      l_wa_temp-matnr = total+3(18).
    l_wa_temp-bmenge = total+95(13).
      APPEND l_wa_temp TO l_i_temp.
      CLEAR l_wa_temp .
    ENDIF.
ENDLOOP.
however the l_wa_temp-bmenge is getting populated as 0.00 however the actual value entered for it is 10

When you are on the table maintenance screen, you can :
1. Goto menu options. Selection-->By Content
2. Choose the fields you want to search data on and Press enter
3. Enter the operator and the value (you can append or insert a new field here as well )
4. Click on the choose button.

Does all RDBMS support auto-increment field?

Hi,
I am designing a java application in which I have to write some logic to auto-increment one database field. Can anyone tell me that all the databases support the auto-increment fields.
Thanks in advance.
Chris

There seem to be two kinds of facility for this in databases. One kind has an auto-increment field. Unfortunately they aren't consistent about how you obtain the value just created after an insert (which you almost invariably require to know). Generally you use a select statement to pick up the value of some kind of last row index function, but the name and syntax varies.
The other kind uses a separate object in the database called a SEQUENCE. You create this with a CREATE SEQUENCE statment, and generally you reference nextval(sequence_name) in the default attribute of the database field.
To get the last allocated sequence number you use select currval(sequence_name)
Again the syntax is a bit inconsistent. You should also probably use transaction isolation if someone else might be incrementing the same sequence.

Auto increment with collection is not working

I am using KODO 3.0 with MYSQL 4.0.16. I have created two JDO object as
follows
BankAccount contains a collection of Contacts object. My metadata looks
like this
<class name="BankAccount">
<field name="contacts">
<collection element-type="Contacts"/>
<extension vendor-name="kodo" key="element-dependent"
value="true"/>
</field>
</class>
<class name="Contacts" objectid-class="Contacts$contactId">
<field name="contactId" primary-key="true">
<extension vendor-name="kodo" key="jdbc-auto-increment"
value="true"/>
</field>
</class>
There is no problem in the persisting of BankAccount object and adding
Contacts to it, but Contacts collation is not retrieved along with parent
object. In the database join table, the contact Id value it is always set
to null.
Things are working well with out contact id in Contacts.
Can anyone help?

How to auto increment a NUMBER(10) datatype

Anyone know the syntax on how to auto increment a number field every time a new row comes in?
TIA
CREATE TABLE loc_color_group_values(
     ID number(10) NOT NULL auto_increment, <----------------
     COLOR_CODE_ID number(10) default 0,
     PROD_LOC_ID number(10) default 0,
     COLOR_GROUP_CODE_ID number(10) default 0,
     PRIMARY KEY(ID)
);

Here is an example:
CREATE OR REPLACE TRIGGER "EXAMPLE_TRIG" BEFORE
INSERT ON "loc_color_group_values" FOR EACH ROW BEGIN
IF :NEW.id IS NULL THEN
    SELECT loc_color_group_values_seq.nextval INTO :NEW.id FROM dual ;
END IF;
END ;This allows you to overide the sequence without having to disable the trigger.

Regarding auto increment

how can i auto increment the number in my table while inserting the data

Good point. If any error occurs during insertion -
the sequence will be broken. Bucause, even if your
transaction failed sequence will generate the new
sequence number. But, as a result of that error -
insertion won't be taken into place. Thus, break your
continous chain.It is probably good point (depending on requirements) irregardless of that.
Sequences ARE NOT for CONTINUOUS number generation.
Sequences ARE for UNIQUE number generation.
Continous chain will break also at least rollback (always) and DB restart as well (unless you haven't specified sequence as nocache which generally is silly idea).

Auto increment option

Is there any option for auto increment the values in the tables. for example if we are inserting 100 data's for first data i should specify 1 and for second data it should specify 2 and goes on.

Hi,
Use Sy-tabix in between loop and endloop.
or sy-index = sy-index + 1.
Check this Example.
TABLES:MARA.
          Selection Screen
SELECTION-SCREEN BEGIN OF BLOCK B1 WITH FRAME TITLE TEXT-001.
RANGES:S_MATNR FOR MARA-MATNR.
SELECTION-SCREEN END OF BLOCK B1.
INITIALIZATION.
S_MATNR-LOW = '000000000000000001'.
S_MATNR-HIGH = '0000000000001000'.
S_MATNR-SIGN = 'E'.
S_MATNR-OPTION = 'BT'.
APPEND S_MATNR.
CLEAR S_MATNR.
            Internal Table
DATA:BEGIN OF ITAB OCCURS 0,
       MATNR LIKE MARA-MATNR,
       ERSDA LIKE MARA-ERSDA,

       END OF ITAB.
            Start of Selection
START-OF-SELECTION.
SELECT MATNR
         ERSDA
         ERNAM
