Auto Increment UDF

Hi there experts,
I'm just curious if its possible to have an auto increment number on udf ? I have a test server and I'm just curios about it but I don't know if its possible or not.
Thanks in advance guys.
Warm regards,
Tony

Hi Tony,
Say you created an udf U_Test for marketing document AR Invoice.
Now you want an auto increment on that udf for every invoice created, then you need to use the following FMS;
Select max(T0.[U_Test])+1 from OINV T0 where T0.Series = $[OINV.Series]
execute this query in query generator and save it. Press AltshiftF2 on udf and assign this formatted search in this udf.
You may set it to auto refresh on docnum else you may press shift+F2 to get the desired output. Hope this helps.
All the best!!
Thanks,
Joseph

Auto-Increment a UDF with correct format

Hope someone can help.
I am trying to auto-increment a UDF and everytime I do it SAP seems to be reformating it incorrectly.
Here is the query:
SELECT CAST(MAX(T.[U_UPC]) as numeric)+1
FROM RDR1 T
The results should look like 12345678
But instead SAP places a value of 12,345,678.00
I have tested this is SQL by itself and it works fine but when I make it into a Formatted Search in SAP it adds the commas and decimal places.
Thanks in Advance,
Craig

Really close,
Here is what I have.
I started out with 84573410001
I need to increment the last 5 digits by 1 each time the formated search is used.
So next the number should be 84573410002, 84573410003, 84573410003, etc....

Auto-Increment a String of data

OK, I see to be going round and round with the same problem.
I have UDF that contains 12 digits but the first 6 digits will always be the same.
The next 5 digits are the set of digits I need to auto increment
The last digit is a check digit that is pre-determined.
So I need assistance on a formatted search that looks at just the 5 digits and auto-increments those.
What seems to be the problems is once the UPC gets 12 digits, it only seems to start auto updating the 12 check digit and I do not want the 12th digit even touched.
I started out with 84573410001
After I made a update to that number the final value of the UDF is 845734100011
When a user used the formatted search the next value it should update is 84573410002
This is the query I got from teh forum a few days ago and it works as long as there is only 11 digits in the UDF, once I add teh 12th digit then it starts to auto increment the 12th digit.
Thanks,
Craig

That was the posting I did the first time around and the Query of:
SELECT str(CAST(MAX(T.U_UPC) as numeric)+1,12)
FROM RDR1 T
Works great when there is only 11 digits to increment but I want to only auto-increment a string of 5 digits with in the value.
First String (Will always be the same) 845734
Second String (THIS IS THE SET OF DIGITS I WANT TO AUTO_INCREMENT) Starts at 10001 and goes up.
Third string - 1 digit that is updated based on a set of values I built into a User Defined table and adds to the first 2 strings based on a comparison.

How to use auto-increment and search option for MS Access DB

Dear All,
I have configured our invoice in Adobe Livecycle and connected it to MS Acess 2007 as per http://forms.stefcameron.com/2006/09/18/connecting-a-form-to-a-database/.
All is working fine, I can insert, retrieve data from DB to invoice and vice versa.
Now I want few things to be implemented on our invoice.
When ever I open our invoice, it populate the first entry from DB, Is it possible to populate the last entry ?
Auto increment invoice number from MS Access DB every time we open our invoice after save.
How to implement search option from DB for invoice number ?
Please let me know if someone can provide me help on my scenario, so that I can share more stuff related to invoice and DB.
Look forward to hearing soon from experts and other team members.
Thanks & Regards

As far as I know there is not any auto increment data type in Oracle. Instead of this you should create a sequence and get the next value of the sequence while creating a row in your table.
CREATE SEQUENCE Test_Sequence ;
CREATE TABLE Test_Table ( Id NUMBER , Foo VARCHAR2(4) ) ;
ALTER TABLE Test_Table ADD CONSTRAINT Test_Table_PK_Id PRIMARY KEY ( Id ) ;
INSERT INTO Test_Table ( Id , Information ) VALUES ( Test_Sequence.NEXTVAL , 'FOO' ) ;

Trying to create cmp correctly(auto-increment);error while running

I am using the latest versions of Jboss(4.0.5.GA) and Lomboz(R-3.2-200610201336) along with SQL Server 2005 and Microsoft's SQL Server 2005 JDBC driver.
Lomboz used xdoclet to create the java files based on the SQL table but it did not put anything in the DoctorBean.java file telling it that the primary key was auto-incremented.
Using the JSP files, I can retreive data out of the database fine so I know the connection and drivers are set up properly.
Here is the error:

Nevermind.. no one bothered to inform the developer that the path to the collection AND the path to the directory that the collection is for are different on this other server.
Fixed.

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?
Regards,
dharmi

Set the following property:

How can i create an auto increment column

Hello Everyone
We are working on an EAM package which has an auto number facility but that is not meeting our requirement because some 10s and 100s of numbers keep on jumping based on the number of records the child table has.Means every record in my parent table will have some child records in another table which we call it a child table.The number of numbers that will be jumped each time will depend on the number of child records it has. Now we want to create a new column and generate a sequential unique number in my parent table with out linking it to its child table and use this number as a reference number. And we cant do that through our package customization. Can any one guide us if we can meet our requirement through oracle triggers or so.
Thanks and Regards

Hi,
For "Auto-Increment" functionality - you can use a combination of a sequence and a trigger like so:
create table roles ( role_id INT
                   , role_name VARCHAR2(30) NOT NULL
                   , creation_date DATE DEFAULT SYSDATE NOT NULL
                   , role_description VARCHAR2(255)
                   , CONSTRAINT roles_pk PRIMARY KEY (role_id)
                   , CONSTRAINT roles_uk1 UNIQUE (role_name)
create sequence role_id_seq
start with 1
increment by 1
nocache;
CREATE OR REPLACE TRIGGER roles_pk_trig
BEFORE
insert on roles
for each row
begin
IF :new.role_id IS NULL THEN
   SELECT role_id_seq.NEXTVAL
   INTO :new.role_id
   FROM dual;
END IF;
end;
/Now any insert which leaves the "ROLE_ID" column NULL will have an auto-incremented value put in for that column. This is similar to an "Autonumber" column in Access.
Hope this helps...
Take care.

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.

Why is Kodo trying to use the jdo_sequence table when we want it to use the HSQLdb identity field ?

We have many users using single field identity and auto-increment together.

How to create auto increment value in my column using identity ?

hi Team,
I have an requirement where i create an auto increment value ,with my table column
Create table Temp(
DeptID int IDENTITY(1,1) PRIMARY KEY,
Name varchar(50),
Emailid nvarchar(50),
Phone varchar(50)
so this is my table structure ,Here my column name is
Deptid here i need to creat an autoincrement value with today's date like below
ex:STM0000120012015
STM0000221012015
STM0000322012015(Currentdate)
.......................................... like this
Here i need only one column like identity column with the given incremental order,not more than one column
so can u pls help me out any one.
Thanks!

Here the output came like this ,
1 STM0000120150121
2 STM0000220150121
3 STM0000320150121
4 STM0000420150121
5 STM0000520150121
6 STM0000620150121

8 STM0000820150121
9 STM0000920150121
10 STM00001020150121 --see this exceed length
and here i dnt need to increment that Stm000010,Here my output will come like this, idnt need to increment my charcter size
1 STM0000120150121
2 STM0000220150121
3 STM0000320150121
4 STM0000420150121

10 STM0001020150121
11 STM0001120150121
12 STM0001220150121
so here i dont need to increment my charcter length(16)
The length should be STM(3char)+00001(5Charcters)+CurrentDateFormat,
see the above suggested o/p
so can u pls help me out Dimant

Auto-increment column increase performance in this case ?

hi.
i have the following facts to construct a set of tables.
1. A Lecturer has an ID, Name and Date Joined
2. A Classroom has an ID, Number Of Students
3. A Lecturer can Teach in Many Classes
4. A Class Can be lectured by Many Lecturers
5. Each Lecture Date should be Stored in the DB.
considering those facts, the following schema can be derived
Lecturer
(Lecturer_ID (PK), Lecturer_name, Date_Joined)
Classroom
(Classroom_ID (PK), NumOfStudents)
Class_Lectures
(Classroom_ID, Lecturer_ID (Composte PK), LectureDate)
this is the normal practice we do.
but what if the 3rd Table is constructed as follows ?
Class_Lectures
(LectureSeriesID (Auto-Increment, PK), Classroom_ID, Lecturer_ID (Composte Unique Key), LectureDate)
if the 3rd Table is created as above, will there be any performance differences ? will the performance improve or get reduced ? any advantages / disadvantages of having that structure ?
please do advise my any further best practices as well.
Thanks and Regards

Filename generation & Auto increment filename

Hi,
I would like my program to create a filename automatically, im using the "Filename Generator" which was available online, and also the "Unique Filename" VI. The way im using this is, I let the user select a path, and feed the path to the filename generator.vi. The output of that VI is the input to the Unique filename.vi .And the output of this VI is the root where the actual output file will be located. Im getting an error:
Error 7 occurred at Open/Create/Replace File in Write Spreadsheet String.vi->Write To Spreadsheet File (string).vi->Write Header & Waveform Ref.vi->Main.vi
I have attached my main VI, and the two above mentioned VIs. Also attached is the png file of the frames that contains these functions.
Is there a way to get over this???
Thank you,
Eureka
Solved!
Go to Solution.
Attachments:
Main.vi ‏111 KB
Filename Generator.llb ‏117 KB
Unique File Name.vi ‏35 KB

I think i see what the problem is,
This function creates a path, but not a file. So, the input given to the write to spreadsheet file is not actually the location of a file, i would say it is something virtual.
If i use the Unique filename.vi alone and not the filename generator.vi, my program works fine, it does increment the filename, but, the user has to select the file every time.
For instance, i have a txt file "Current". The VI generates a file path for "Current(1)" and writes the data in the new file.
The next time, if the user fails to select "Current(1)" as the input path, and if the input path is just the same as the 1st run, it over writes the data in "Current(1)", as expected!
The basic problem is, i need to avoid over writing data. Because, i read the waveforms from the file and it will me messed up big time.
Is there a function to auto-increment filenames as we write them?
Thank you,
Eureka

Auto-increment identity column through procedure in oracle 10g on windows

Hi,
I need identity primary key which should be auto increment before while inserting data into table.
for this i had use sequence and then trigger to increment it.
but now i need to increment it in Procedure, while my procedure is having code to insert data in same table which has primary key

Unfortunately, Oracle does not have auto-increment columns. A sequence is an auto-increment object, and it's the right way to automatically generate unique identifiers, but you need to explicity reference the sequence, either in you DML statements, or in a trigger that will automatically fire before a DML statement.
but now i need to increment it in Procedure, while my procedure is having code to insert data in same table which has primary keyAre you saying that you need to increment the sequence, completely aside from INSERTing into the table?
If so, just reference sequence_name.NEXTVAL wherever you want to. In PL/SQL, you can say
SELECT sequence_name.NEXTVAL
INTO number_variable
FROM dual;This works in any version of Oracle, but starting in Oracle 11, you also have the option of referencing te sequence without using dual, or any other table.
I hope this answers your question.
If not, post a complete script that people can run to re-create the problem and test their ideas.
For example:
-- Here are the table and the seqauence that I created:
CREATE TABLE table_x ...
CREATE SEQUENCE ...
-- Here is the BEFORE INSERT trigger I wrote:
CREATE OR REPLACE TRIGGER ...
-- The trigger works exactly how I want it to in statements like this:
INSERT INTO table_x ...
-- So there are no problems (that I know of) with anything up to this point.
-- Now I want to use the same sequence to ...
-- so that when I execute a statement like this
-- then the next time I add a new row to the orginal table, like this
INSERT INTO table_x ...
-- then the contents of table_x should be ... because ...

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.
