Automatically incrementing an index

There is a way to automatically increment a index in Oracle when a insert is carried out without calling a trigger. But I cannot remember how to do it.
So if I have emp_id as the primary key for the table emp, the last one is set to 105, when I do an insert on emp oracle will automatically set it to 105
Thanks for any help Tony

Are you talking about using a sequence ?

How to create an automatically increment column in Oracle DB Table?

Hi To All
Here I am trying to create a table in Oracle that creates an automatically increment column in Oracle DB Table. i searched almost all Forums.(Even in Oracle). They are saying that, that logic u must implement in Java Code.(*Takes Maximum no from table, add +1 to it, and store it back again)*. apart from this, while creating an table in Oracle, is there any facility like MySQL Database? please help me. Thanks in advance.

Hi BalusC
Thanks for Your Response and clue. with that, i succeeded in my application. Thank you very much. here i am giving you the details which i did.
1. I Created a table named orders in Oracle like this.
   CREATE TABLE ORDERS (ORDER_ID NUMBER, CUSTOMER_ID NUMBER, ISBN NUMBER,
                               DESCRIPTION NCHAR(5));
                   2. I created one sequence in Oracle like    CREATE SEQUENCE SEQ01 INCREMENT BY 1 START WITH 1000     3. Then i have written jdbc program like this
import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
public class SequenceTest {
     public static void main(String[] args)throws Exception{
          try {
          Class.forName("oracle.jdbc.driver.OracleDriver");
          Connection con=DriverManager.getConnection("jdbc:oracle:thin:@192.168.1.135:1521:orcl","scott","tiger");
          String cols[] = {"ORDER_ID", "DESCRIPTION"};
          PreparedStatement pstmt = con.prepareStatement("INSERT INTO ORDERS (ORDER_ID, CUSTOMER_ID, ISBN,DESCRIPTION) VALUES            (SEQ01.NEXTVAL, 104, 966431505,?)", cols);
          pstmt.setString(1,"Desc3");
          pstmt.executeUpdate();
          ResultSet rs=pstmt.getGeneratedKeys();
                System.out.println("---- One Row Inserted ----");
          } catch (Exception e) {
               System.out.println("---- Failed Due To "+e);
   4. When i ran above program 5 times, i got the following Data into my Oracle Table (select * from orders)
ORDER_ID CUSTOMER_ID       ISBN DESCR
      1000         101 966431502 Desc0
      1001         102 966431503 Desc1
      1002         103 966431504 Desc2
      1003         104 966431505 Desc3
      1004         104 966431505 Desc3
      1005         105 966431506 Desc4
6 rows selected.
But i dont know how to do this type of program with out using prepared statements. i tried, and i got exception *"Missing Expression"* .
Once again Thank You very much for your clue.

Automatically increment a date parameter

Is it possible to schedule a workbook for a period of time and have the date parameter automatically increment to the next date in Discoverer?

Hi
Yes of course. When setting up a scheduled workbook, in the Step 1 screen of the Schedule Workbook dialog there are two radio buttons with a title: How often do you want to repeat the schedule? You can choose Never or Repeat Every and then set up a repeating schedule to run anyhere from x minutes to x years. In the Step 2 screen is a box titled Delete results automatically after. You get the opportunity to say how long, in days, the results of previous runs should be kept.
Do you have a copy of my Discoverer 10g Handbook from Oracle Press? If so, please take a look at pages 478 to 495 in chapter 14. Pages 480 and 481 in particular describe in detail the steps above.
If you don't have a copy you might want to consider getting one. I worked very closely with Oracle Corporation to get the book as accurate as possible and yes while I make a little money from you buying it that's not why I recommend you get it. Even though I wrote it I use it myself every day as it is over 1,000 pages long and is crammed with as much knowledge as Oracle Press would allow me to do at the time.
I hope this helps
Best wishes

Auto increment array index

Hi,
I have a small problem which i am trouble trying to figure out. Well i have 2 arrays with equal number of elements in each array. What i intend to do is to take the first element from each array and use them in a mathematical expression. Then i would like to increment the indexes of both arrays programmatically and then access the next elements from each array. This procedure is to continue till the end of the array(s). How can i do this. I have tried a couple of things but just dont seem to be able to get around the problem. Help!!!
I have attached the sample code below. I am using version LabVIEW version 8.5.1.
Thank you,
Arun

Sample code 1.vi ‏11 KB

Feed both arrays into a for loop. Have the tunnels set for auto-indexing. Do the math. Have the tunnel going out the right hand side be set for autoindexing.
I would recommend looking at the online LabVIEW tutorials

Problem while incrementing the index

Hi Friends,
I am working on creating Credit memos and return orders through BDC. For the item level, I am incrementing the index in order to enter the MATNR, POSNR, KWMENG etc. I have seven lines open in my screen. So when I have an order greater than or equal to seven lines, the program is showing an error that that line does not exist in the screen. Please, let me know what is the solution for this.
Thanks,
Raj

Srinivas,
I am giving a new line from the very first line. It is working fine till the seventh line. But after the seventh line, the cursor is coming to the MATNR position and the proghram errors there. I am also attaching my code. If you can correct me from that, it would be helpful.

What is the easiest way to always increment to index 0 only for a multi-element array ?

The premise is to populate a spreadsheet from left to right in the same row but incrementing the column letter only (ie - B4, then C4 etc). Attached I have customized an existing example VI that works for a 2 element array (ie - B4) but does not work for a 3 element array (ie - B40, then becomes B50). Keeping it simple, what is the best and easiest way to modify my existing code to always check the array size and automatically index back to 0 in order to properly increment the first letter only (ie - B) and not the number (ie - 4) ?
Thanks !

Automatically incremental updates/reindexing?

Hello all,
is it possible to configure incremental updates which start automatically? In my opinion it is far too much trouble if the administrator has to start this always manually...
I need this function for new, changed and deleted documents (I want to search these).
Thank you for suggestions.
Kind Regards
Susanne

Hi Susanne,
you can define a crawler schedule on the index to run daily, weekly or monthly. This is done when you create the index initially, but you can modify the schedule afterwards in the Index Administration iview.
Whether it is an incremental update or otherwise depends on the crawler parameters that you use.
See the SAP Help documentation for <a href="http://help.sap.com/saphelp_nw2004s/helpdata/en/e6/ed5b825590c74e8a963289450f98f6/frameset.htm">Crawlers and Crawler Parameters</a>.
You need to configure the following crawler parameters:
"Verify Modification Using Checksum"
"Verify Modification Using ETag"
"Condition for Treating a Document as Modified"
Hope this helps,
Robert

How can I increment the index of an array in a formula node?

How can I automatically increment an auto incremented column?

Hello!
I have a table with an auto incremented "id" field.
It looks like this:
id (PK, auto_increment) name address phone
I would like to make an insertion like:
INSERT INTO Person (name, address, phone) VALUES (?,?,?)
...but it says that all fields have to be used.
I get
java.sql.SQLException: Field 'id' doesn't have a default value
How can I bypass this?
I have looked at [this example|http://blog.taragana.com/index.php/archive/java-how-to-get-auto-increment-values-after-sql-insert/] , but it didn´t work for me, it still says the "id" column has not a default value:

Sorry, it is a MySQL database.
The table consists of 4 columns:
id (PK, auto_increment)
name (Varchar)
address (Varchar)
phone (Varchar)
If I use PHPMyAdmin to insert a new row, then this query works:
INSERT INTO `mydb`.`person` (
`id` ,
`name` ,
`address` ,
`phone`
VALUES (
NULL , 'Test', 'Roxxor', 'Europe', '12345'
);{code}I tested to use the method setNull() on the first column in the preparedStatement but it didn´t work.
Do you need more info from me to be able to help me?
I have tried this (but got the error that the "Field 'id' doesn't have a default value"):
[code]con.setAutoCommit(true);
            String query = "INSERT INTO person(id, name, address, phone) VALUES (?, ?, ?, ?)";
            PreparedStatement stmt = con.prepareStatement(query);
            stmt.setNull(1, java.sql.Types.NULL);
            stmt.setString(2, name);
            stmt.setString(3, address);
            stmt.setString(4, phone);
            stmt.executeUpdate();
            stmt.close();[/code]

Statistics automatically gathered on indexes?

I haven't paid much attention to this in the past, but I notice in XE that user_indexes
is automatically populated when you create an index - num_rows, last_analyzed,
etc. I suppose the simple act of creating the index collects enough data to
provide those statistics, and Oracle uses them instead of throwing them away.
Below is output from a simple script run in XE creating a table and four indexes.
user_indexes.last_analyzed is not null even without any explicit
gathering of statistics. num_rows, etc. are all populated...
This does NOT happen in Enterprise 9.2.0.4...
SQL> drop table pkt2;
Table dropped.
SQL> create table pkt2 as
2 select rownum row_num, rownum / object_id not_row_num, 2 * rownum / object_id not_row_num2

Workflow to automatically increment Priority by age of Incident Request

Looking to find a way to automatically adjust an Incident Request's Priority based on the age of the incident (ie...started as a priority 5 and has not been completed in 2 days, so Priority increases to a 4...etc). I realize Priority is calculated as
a function of Impact/Urgency - so maybe a workflow that can increment either one (or both) based on the relative age of the Incident Request.
Having difficulty locating information on this topic.
To be honest, I'm not sure this is accomplishable through a Workflow, perhaps Orchestrator is required?
All help and suggestions are appreciated.
Thanks in advance,
David

the Priority is calculated based on Impact (i.e. how damaging the problem is) and Urgency (how important the need is) based on the priority table in the Incident settings. Changing the priority directly can be done, but the workflows and incident form
code will automatically recalculate it based on the incident settings, so the change will probably not stick.
the typical method to do what you want to do is to use a SLO,
Service Level Objective, to flag incidents that are overdue (or nearly overdue) for immediate action. Typically a
notification is sent to the assigned analyst when the SLO level changes.

Automatic increment posting

Dear expert,
Is is possible to post increment automatically at the anniversary date of joining,considering 240 wokdays in that year.

Hi Sujata,
I think u can do this using Monitoring of Task where in once the employee completes 240 working days...the adminstrator gets intimated about it and u can run payroll action for that....

Automate command to index in 11G

Hi,
We're going through manual migration of our 5.2 instances over to 11g, and have a big list of indexed attributes. It is really a tough jobs to run multiple commands per suffix across various environment. I was wondering if someone has a better way to help me out.
Thanks, John.

For initial system configuration, I usually put my index configurations in an LDIF and then replace all the non-system indexes with mine. As long as you do this before an LDIF import that's about all there is to it. Of course there are dsconf commands to do it too if you want to go that way. If you are initializing data from a binary backup, you just need to make sure the backup comes from a system with the same indexes. IIRC the restore will fail if that's not the case.
If what you are talking about is a multi-system reindex utility intended to change existing indexes on multiple systems that are currently in service, you need to be very careful with that. Since reindexing puts the backend into readonly, that kind of tool will have the potential to put an entire topology into readonly, with an associated topology-wide write outage. We had a thread about that a while back. If this forum's search tools worked better, I'd probably be able to fish that out for you.
