I can't for the life of me find out how to auto increment the primary key like you can in access. I want to use userIds that will auto increment as new users are added. Can you guys help me out at all?
As of now I used this code as an example. I'm using SQL server 2005
CREATE TABLE Customer
(SID integer PRIMARY KEY,
Last_Name varchar(30),
First_Name varchar(30));
I know about IDENTITY(x,x), but I already have that for my primary key.
I also want to add into the same table a row that auto increments, but without using IDENTITY because it won't let me use IDENTITY more than once per table.
My question is how to get IDENTITY_INSERT Incriment Primary Key ID roll back when the application fails.
Using TransactionScope with single connection in DataObject. I am trying to insert row in two dataTable using its own tableAdapter (two tableAdapter).
I have Product table with ProductID primary key with incriment identity. and that ProductID is used to insert row in ProductHistory Table. Lets say Product table has the last ProductID=8 (8 rows) and the next ProductID will be 9.
When I insert row in both table and if the second table insert fails both gets roll back (which is good). but when I insert again another time the Product ID=10 not 9. Is there any way to roll back the ProductID in Product table so when i insert next time it has incriment number instead of gap.
Hi,
I have recently been looking at a database and wondered if anyone can tell me what the advantages are supporting a unique collumn, which can essentially be seen as the primary key, with an identity seed integer primary key.
For example:
id [unique integer auto incremented primary key - not null],
ClientCode [unique index varchar - not null],
name [varchar null],
surname [varchar null]
isn't it just better to use ClientCode as the primary key straight of because when one references the above table, it can be done easier with the ClientCode since you dont have to do a lookup on the ClientCode everytime.

How do I make a Primary Key in a table automatically increment as a new row of data is entered? do i have to do it with a trigger?? if so what is the code behind it....what I have is a Applicant table, which holds the ApplicantID (<<<needs auto incremented), FirstName, LastName, Address, City, State, Zip, and PhoneNumber. I enter all the other information through visual web developer, and what I need to do when the hit submit on the form with the data i want to automatically set an id right there. any suggestions will help!
View 3 Replies View RelatedHi all,I have a table where I have my ProdPK set up as Primary key, turned on "Is Identity" and set the Identity increment to 1. But each time I add a new item, the number incremented by 2... I have couple of other tables and they are all fine, just this particular table increased twice as it should. I check the setting against other tables and everything seems to be the same. By the way, this is adding the data to the table inside MS SQL Server Management Studio manually. I haven't done anything in the ASP.NET page yet. Thank you very much,Kenny.
View 5 Replies View RelatedDear all,
I am using SQL express 2005 in visual studio 2008. I would like to use Form View to insert new record in the table. There is a column call "id". I think it is too stupid to let user enter a unique identifier instead of generating by the system.
I know how to generate a random integer number in a normal TextBox. However, when I edit the InsertItemTemplate, I cannot modified the value of that textbox. For example, i couldn't use "TextBox1.Text = temp;" here. How can I achieve to change this TextBox's value by the system that I would like to generate a random interger. Thanks a lot.

How do I make my Primary Key Auto Increment from Enterprise Manager?
Thanks
I discovered the cause:
in SQL Server Enterprise Manager, open up db tree, right click the table, go - 'design' and set 'Identity' to yes.
I want a table to have an int auto primary key, that will fill in deleted rows.
EG
1
2
4
5
8
The next primary key should be 3 (NOT 9)
This table changes often, so just adding 1 to the last number used, will fast run out of numbers.
The table is accessed by many users, so it can not be manually generated.
I was just wondering on a very simple database table with lets say a primary key set to columb ID and another columb lets say products, can you make the primary key automaticly increment its self whenever a new entry has been put in?For instance say I have this table set up with ID Being the primary KEY, Columb 1 = ID( INT ), Columb 2 = Products ( VarChar(50) ), and have the fields ID = 1, and products = my product.....and if a user inserts a new record say from a gridview or some sort of data entry the second ID Feild will automaticly be 2 and the products gets updated per user input.......I'm very sorry but I'm having a hard time putting this into words for some reason..umm basicly user adds something into the products feild and the ID field automaticly increments one number higher from the last one?ThanksAdam.
View 4 Replies View RelatedOk - I have two tables that are relational. I have been inserted data into the tables because of testing. I also have been deleting data. My question is how do I reset the auto-incremented Primary key values.
For example:
Primary key of table one is bizID. Well there are only 3 record currently in the table. The bizIDs are 1-3. If I insert another record the bizID will be 88 because that was the next auto-incremented number. I obviously deleted the other records. I want to start the primary key value over from zero. How do I accomplish this? thnks
How to auto increment an alphanumeric Primary Key in SQL? :( Because I want to add something like this in the Primary Key, for example i'll add a new data with an alphanumeric value of ABC-0001, then I'll add another 1, and it auto increments to ABC-0002 and so on.. How can I do it? And if I'll add a new alpha character in the Primary Key field, for example DEF-0001, then I'll add another and it auto increments to 002, and so on, and it will go back to 0001 if i'll use another combination of alpha characters. for example, i'll add a new alpha character AAA, will it go back to 0001 or it will continue? T___T I hope u get my point.. I want my table to look like this if i have added the dataABC-0001ABC-0002DEF-0001DEF-0002AAA-0001then if il add a new 1, for example ABCit will auto increment to 0003 in the same field, it will look like this after addingABC-0001ABC-0002ABC-0003DEF-0001DEF-0002AAA-0001Will it be possible? :(

I'm still looking for a solution on msdn, but i've decided also to post my question here.
How can i reset my primary key field auto-increment back to 0 in runtime (or in designtime)?
The table I am using have a column called Key which is the primary key of the table and a auto number. This primary key is not a foreign key in any other table.
I need to write SQL to drop the current primary key and add a new one Say "RecordId"
as the new primary key and which should be a autonumber too.
any idea.
thanks in advance
Hey there :)I'm using Ruby on Rails to create a migration of a legacy database onan MS SQL Server. I'd like to name my constraints myself, such as'pk_authors', but in the cases where a table has an auto incrementedIDENTITY(1,1) id field, Rails takes over and adds the primary keyitself when creating the table.This is fine, except then the constraint gets a name like'PK__authors_384934' which is not very intuitive or easily remembered;)I'd like to just throw in an 'ALTER TABLE authors...' statement justafter that table has been created, but I'm not sure how to go aboutrenaming the auto generated constraint since the name it gets ispartially random. Is there any way to indirectly refer to theconstraint like 'RENAME PRIMARY KEY CONSTRAINT ON authors TOpk_authors' or something like that, so that I can rename theconstraint?Thanks in advance,Daniel Buus :)

just a question regarding database design
i have a table with an auto-generated primary key but the problem is this:
say i have 4 records,so logically they'll be numbered 1 to 4.so the problem is whenever i delete all records and add new ones,the numbering will start from 5 and not 1 again.
how do i remedy this?

Hi. After inserting data (new row) by using DetailsView control, how to read auto incremented primary key (identity) of this new row from sql database to use it as parameter passed to stored procedure?
View 4 Replies View RelatedHi guys,I followed the ASP.net official tutorial to create a DAL & Business Logic Layer (http://www.asp.net/learn/dataaccess/tutorial02cs.aspx). I have a table with a int ID field. I wish to write a function to add a new entry into this table but have the ID field auto-increment.The ID field is set as the Identity Column and has a Identity Increment & Seed of "1". If I manually go to the table and insert a new record leaving the ID value null it automatically increments. But if I create a C# function to add a new entry I get an error saying that the ID field can't be Null. Is there any way to use the Update method as shown on line 14 below to add a new entry but with it automatically incrementing? I did create a function called InsertDevice that simply inserts the other fields using a SQL INSERT and it auto-increments fine, just wondering if there is a way to do it using the DataTable and the Update method? Thanks for any help!!! 1 public bool AddDevice(string make, string model)

I have a table that has a primary key that is auto incremented by 1. This table's data is cleared out periodically and as data gets added the auto id primary key continues to increase in numeric value. Once the data is cleared from the table the auto id names could be used again(the eventId is not stored) Currently the eventID is at 26,581,399. I know the maximum int value is 2,147,483,647.
How should I handle this? or rebuild the table every time the data is cleared(problematically)?
I have imported a whole bunch of tables. Most of them have an ID (int) column. Is there a way to set the ID columns across all tables to auto increment Primary Keys in bulk?

Since upgrading from SQL Server Management Studio 2008 R2, I've noticed that it no longer autosaves queries that have not been manually saved first. If a file has been manually saved the autorecover files end up in the following directory:
%appdata%MicrosoftSQL Server Management Studio11.0AutoRecoverDatSolution1
However, I have ended up in the situation where I have unsaved queries when my computer has crashed and have not been able to recover them.
I have also found references to .sql files stored in temp files in the following directory, but the files here seem to be very haphazardly caught:
%userprofile%AppDataLocalTemp
I have an MS SQL Server table with a Job Number field I need this field to start at a certain number then auto increment from there. Is there a way to do this programatically or within MSDE?

We have a table, which has one clustered index and one non clustered index(primary key). I want to drop the existing clustered index and make the primary key as clustered. Is there any easy way to do that. Will Drop_Existing support on this matter?

I have the following table
CREATE TABLE [dbo].[property_instance] (
[property_instance_id] [int] IDENTITY (1, 1) NOT NULL ,
[application_id] [int] NOT NULL ,
[owner_id] [nvarchar] (100) NOT NULL ,
[property_id] [int] NOT NULL ,
[owner_type_id] [int] NOT NULL ,
[property_value] [ntext] NOT NULL ,
[date_created] [datetime] NOT NULL ,
[date_modified] [datetime] NULL
)
I have created an 'artificial' primary key, property_instance_id. The 'true' primary key is application_id, owner_id, property_id and owner_type_id
In this specific instance
- property_instance_id will never be a foreign key into another table
- queries will generally use application_id, owner_id, property_id and owner_type_id in the WHERE clause when searching for a particular row
- Once inserted, none of the application_id, owner_id, property_id or owner_type_id columns will ever be modified
I generally like to create artificial primary keys whenever the primary key would otherwise consist of more than 2 columns.
What do people think the advantages and disadvantages of each technique are? Do you recommend I go with the existing model, or should I remove the artificial primary key column and just go with a 4 column primary key for this table?
Thanks Matt
Does anyone know how to use for xml auto that will format an xml response to show the parent/child relationships? I currently have the parents and children in a temp table and can only get a formatting so that each one is returned at a parent. how can i select the results from the temp table so for xml auto will return the properly formatted xml file?
this is also for the TreeVeiw control.
The upgrade adviser for for 2k5 says something about derived tables being handled differently between 2k and 2K5 and it says to query the tables directly but this does not seem to make much sense because I thought FOR XML AUTO just created some generic XML for presentation purposes. These 2 stored procedures that it is complaining about do query the tables directly and they use the FOR XML AUTO to control the output.Does anyone know if I have to worry about this? I am tempted to let this slide and check out this part of the application after the migration happens tomorrow for QA to start testing.Yes I have been googling, checking my books and digging around in BOL. I am not seeing anything.DISREGARD: I found my derived table. It appears to change the output of the XML. Perfect.
