Can i use an auto increment value in ldap entry?
For example i can insert, for each ldap entry, an id that is different from the previous one.
Thanks

ThanksI don't think that there is a "built-in" way to do this, but I have seen several methods for doing this. One way is to use a primary/unique key from another system (i.e. an employee number from an HR database), another way is to create a GUID for each object prior to creating it in the Directory. You can muck around in the schema to set a attribute globally unique, if you want to avoid doing the lookup for an existing entry when you create a new one.

LINQ: Update a column with auto increment value

Hi All,
Greetings.
I am very new to C# (though with lot of experience in VC++). Now a days, I am engaged in a C# project where I need to deal with ADO.NET DataTable and related classes. I am stuck up in a scenario as follows:
I have a data table (of DataTable type) pre-populated with many rows (50000+), parsed from a log file. Now I need to add a column that will be holding index number for each records; eg. 1, 2, 3......
I have tried to add the auto-incremented column dynamically, with seed = 0 and increment = 1, but it is not working.
Is there any LINQ query that I can run to update the DataTable at once? Or foreach loop per DataRow is the only option here?
I appreciate any quick suggestion on this.
Thanks in advance.
Sanjoy Jana.

You should add the auto increment column to the DataTable before you pouplate it with the other data:
//1. Create a datatable
DataTable dt = new DataTable();
//2. add the autoincrement column:
DataColumn column = new DataColumn();
column.DataType = System.Type.GetType("System.Int32");
column.AutoIncrement = true;
column.AutoIncrementStep = 1;
column.AutoIncrementSeed = 1;
//3. Fill the dataTable using an SqlDataAdapter or whatever
dt.Columns.Add(new DataColumn("name"));
dt.Rows.Add("1");
dt.Rows.Add("2");
dt.Rows.Add("3");
dt.Rows.Add("4");
Then you don't have to add the "auto incremented" values yourself in some kind of a loop (using for example LINQ or foreach).
If you want to know how to poplulate the DataTable from a database query using an adapter, please refer to the following page:
http://www.dotnetperls.com/sqldataadapter
Hope that helps.

How to get auto-increment value after insert on ACCESS db?

When you insert a new record to a table with an auto-incrementing key, how do you find the value for the row you just inserted? This works differently with different databases. I know how it's done on ORACLE and mySql.
How does it work with ACCESS through ODBC? How about MSSQL?

I have discovered there's a LAST aggregate function which when I've tested it gets the just inserted auto-increment, but I'm not sure if it's reliable. You have to do:
SELECT LAST(index-field) FROM table
That ought to be faster than MAX, which I've noticed some people use. Persumable LAST will get the value from the last row in the table's natural order.
In fact an auto-increment field has no business filling in missing slots since the main point is a a foreign key in other tables and a foreign key pointing to a deleted table row ought to be invalidated, not point to some unrelated successor record.
I could use a separate table as a source of counters, of course, though that's one more call. In either case I'm worried about thread safety. In Oracle there are special sequence objects for this purpose which are incremented and read atomically. I'm not sure if the access driver transaction handling works adequately.
Perhaps the safest approach might be to use a separate sequencer table and Java sychronisation to serialise access to each row in the sequencer table (assuming all the access is from the same app).

Update table column with same auto-increment value, via T-SQL stored procedure

Good Evening to every one,
I have a table 'Contracts' as we can see in the picture below (I exported my data on An Excel Spreadsheet). Table's primary key is 'ID' column.
I am trying to create a stored procedure (i.e. updContractNum), through which I am going to update the 'Contract_Num' column, in every row where the values on Property_Code, Customer, Cust_Category and Amnt ARE EQUAL, as we can see in the schema above.
The value of Contract_Num is a combination of varchar and auto_increment (integer). For example, the next value on 'Contract number' column will be 'CN0005' for the combination of 11032-14503-02-1450,00
I' m trying to use CURSORS for this update but I am new in using cursors and I am stuck in whole process. I atttach my code below:
CREATE PROCEDURE updContractNum
AS
--declare the variables
DECLARE @CONTRACT_NUM VARCHAR(10); -- Contract Number. The value that will be updated on the table.
DECLARE @CONTRACT INTEGER; -- Contract number, the auto increment section on contract number
DECLARE @CONTR_ROW VARCHAR(200); -- Contract row. The row elements that will be using on cursor
DECLARE CONTRACT_CURSOR CURSOR FOR -- Get the necessary fields from table
SELECT PROPERTY_CODE, CUSTOMER, CUST_CATEGORY, AMNT
FROM CONTRACTS;
OPEN CONTRACT_CURSOR -- open a cursor
FETCH NEXT FROM CONTRACT_CURSOR INTO @CONTR_ROW
WHILE @@FETCH_STATUS = 0 -- execute the update, for every row of the tabl
BEGIN
--update Contract_Num, using the format coding : contract_number = 'CN' + 0001
UPDATE CONTRACTS
SET CONTRACT_NUM = 'CN'+@CONTRACT_NUM+1
END
CLOSE CONTRACT_CURSOR
Thank you in advance!

You dont need cursor
You can simply use an update statement like this
UPDATE t
SET Contract_Num = 'CN' + RIGHT('00000' + CAST(Rnk AS varchar(5)),5)
FROM
SELECT Contract_Num,
DENSE_RANK() OVER (ORDER BY Property_Code,Customer,Cust_category,Amnt) AS Rnk
FROM table
)t

Add an auto incremental value to TITLE field.

Hi, i am currently working on a custom list in SharePoint 2010 and there is a title field. I would like to append an auto incremental variable to "Request" to make it look like:
Request 1
Request 2
Request 3
and so on...
As you can see below, i tried to use the calculated value Request+ID, but it didn't work out. So is there anyway to solve this problem?
<input name="ctl00$m$g_0bb0fcf5_65ea_4af9_ba76_7c0babad1a82$ctl00$ctl05$ctl00$ctl00$ctl00$ctl04$ctl00$ctl00$TextField"
type="text" value="[Request-]&[ID]"
maxlength="50" id="ctl00_m_g_0bb0fcf5_65ea_4af9_ba76_7c0babad1a82_ctl00_ctl05_ctl00_ctl00_ctl00_ctl04_ctl00_ctl00_TextField"
title="Title" class="ms-long ms-spellcheck-true" /><br />

Hi andylow,
You can also accomplish this without using a workflow but with a custom form on your list. To do this take the following steps:
Make sure that the title field of your list is not a required value
When you're in the list, click on the List tab in the ribbon
There select "Customize Form"
Your form will now open in InfoPath. In the right hand menu you will see all your data fields.
Make the Title number field "Read Only". To do this right click the field, select properties, click on the second tab and select Read Only
In the menu bar, click on Manage Rules
Now click the Data tab in the menu and select Sumit Options
In the menu that opens select the option to run rules before submit
Now there will be a button available in the menu for Submit Options, click on that
Now you can add rules and actions on the submit action
Create a new Action rule and call it Initial Save
As condition for the rule, set the condition that the Title field must be blank
The first action of the rule will be to Submit the form. When the form is submitted it will be assigned an ID, before that will be blank
Now add an Action to set a fields value.
Select the Title field as the field to set
You can set a hard coded value for the value to set but you can also click the function button, click on that
Now another window opens where you can add fields, functions etc.
Now first select the concat function from the function menu
Then double click the first link in the resulting function and type Request
Now double click the second link and select the ID field
Now get rid of the last remaining arguments in the concat function
Click OK until you're back in InfoPath
Now set one more action to submit the form again
Now ad a second rule and call that Edit
As condition for the rule, set the condition that the Title field must be not blank
Add the Submit Form action for this rule
Now you can publish your form with the Quick Publish button. This is a Blue circle with a white upward arrow and a lightning bolt next to the save button in the top menu bar.
Now when you add a new item and save it, the title will be set to Request&ID. When you edit the form no changes will be made.
Cheers,
Eduard Spelier

Auto increment VALUE attribute extension

I was wondering if there was such an extension or a built in
tool for Dreamweaver that searches for all <INPUT> tags of
TYPE 'checkbox' and sets a unique value for the VALUE attribute.
Example:
I have 3 checkboxes as follows:
<INPUT ID="chkOption1" TYPE="checkbox" VALUE="checkbox"
/>
<INPUT ID="chkOption2" TYPE="checkbox" VALUE="checkbox"
/>
<INPUT ID="chkOption3" TYPE="checkbox" VALUE="checkbox"
/>
and I want the end result to change the VALUE attribute as
follows:
<INPUT ID="chkOption1" TYPE="checkbox" VALUE="1" />
<INPUT ID="chkOption2" TYPE="checkbox" VALUE="2" />
<INPUT ID="chkOption3" TYPE="checkbox" VALUE="3" />
Problem is that I have thousands of those checkboxes instead
of 3. So I was thinking maybe there is a value incrementing tool
available somewhere that someone might know of that parses through
all checkboxes or input tags.
I hope that explains it. Thanks in advance guys.

I think I know what you are wanting. You want to find and
replace all the <input> tags or rather checkbox value. Well
the only simple way is to go to the edit menu in Dreamweaver 8 and
go down to: find and replace. Set it up so that is covers the
entire website not just the page you are working on. You will need
to put in the find box this code:
VALUE="checkbox" />
Then in the replace box:
VALUE="what ever value" />
maybe this will help, hope it does!

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.

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);

Hi Jay,
You can use the Item Id field of the SharePoint list which will get incremented by 1 whenever you add the new item.
you can refer the below threads for other options of auto increment id

Identifying auto-increment columns

Hi,
I am developing a database management package for mysql. I want to be able to provide a sql dump facility, which will produce the sql code for creating a table and populating it.
I do not seem to be able to find a function for identifying if a field is auto-incrementing?
The only thing that I could find it the DatabaseMetaData.getTypeInfo() will let you know if a field can used for an auto-increment value, not if it is actually auto-incrementing.
Please help!

If you do a query of this table and then have a look at
the ResultSetMetaData you can use the methode:
boolean isAutoIncrement(int column)
Indicates whether the designated column is
automatically numbered, thus read-only.
Or you can use the MYSQL-command :
show columns from table to get all the info of each
column.
mysql> show columns from table;
-----------------------------------------------------------------------------+
| Field | Type | Null | Key | Default | Extra |
-----------------------------------------------------------------------------+
where the Extra column contains 'auto_increment ' if it is...
...what in fact is not that DB-independent.....

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.
