Identity/autonumber Fields
Sep 13, 1999
I am experiencing a problem with the identitynumber field in SQL vs the autonumber field in MS Access 97. When I open the Member Contact form(Access), it generates the autonumber on the form, which is then visible on the form itself. That form has several pulldown/pop-up boxes which are used to select criteria. One of the form buttons, the Add Comments button, once pushed, it brings up a Comments form. This Comments form references the autonumber that was generated on the Member Contact form in order to open itslef. The information is then entered into the Comments form and the form is then saved. All the selected information is saved to that record upon the saving of that form.
Now, my problem has to do with getting the identity number(SQL) to generate on the Member Contact form and also allowing the Comment form to open by referencing that generated identitynumber just like Access does without having to save the record first then coming back and adding a comment later.
Do anyone know if it is possible? If so, does anyone have any suggestions on how to generate a identitynumber before saving the entire record?

I'm in the process of converting over an Access database - The existing Forms, Reports, etc are staying within the Access front-end and the Tables are now linked to the SQL database. The only problem is, most of the Tables contain Autonumber fields, so although they converted over to Identity fields, existing records work fine. When I try to add a new record, it doesn't automatically enter the next available Autonumber/Identity until I select a record which already exists to force it to update itself. When I add a new record using the original Access database, as soon as you start entering information into the new record, the next available Autonumber automatically appears. Any suggestions on forcing it to automatically appear using the SQL database and an Access form????

Hi there,
I'm fairly new to the field of database design, my professionalism is in internet solutions but i hope someone can help me out with this one. If you have some questions about internet solutions just e-mail me.
I have designed a database in Access 2000 and then upgraded it to a pre-installed SQL Server 2000 (done by someone else). Only now the 'autonumber' from Access was transformed into an 'identity'. But the real problem is that my database was based on first getting an ID. Now i first have to fill in the fields to get an ID afterwards :-S
Can someone help me out how i can get an ID when something is first entered, just like Autonumber from Access 2000?
Many many thanks,
Paul

I am building a database for a new project. I am not a DBA or a database designer so please bear with me on this question.
My boss believes that the only time to use an identity column is when we cannot determine a unique primary key. On tables where we can determine a unique primary key identify fields are a waste of reasources. For instance, one of the tables that I need to create is a customer table. Since all of our customers have unique customer numbers my boss believes that in this case an identity column is useless. I don't have enough experience to determine if he is correct or not.
Can someone please explain the pro's and con's of using identity fields to me.
Thanks

Hi!
a) PROBLEM 1:
I have set up my main database like this (of course I'm showing an abbreviation):
company - int (identity)name - nchar
I have several companies stored in the previous table. Now I have another table with messages:
company - int (related with the company of the previous table)messageID - int (identity)contents - nchar
company and messageID are the main key of this table. I want to set the messageID column to change automatically. Since I declared it as identity it is working fine, but I was looking to start it on 0 on every new company:
Company messageID0 00 10 21 0 <- Here the company changed, so the messageID resets1 11 21 32 0 <- Again2 1
Any suggestions?
b) PROBLEM 2:I have my database stored locally on my computer. When I finished working with the database it has a lot of data for testing. I want to upload the database to my hosting provider or to my customer's. But the identity columns keep incrementing since the last value of my tests, so it's kind of annoying to see values as: 1250, 223, etc. when I expect to see 0,1, 2 and so on. Also, for receipts this is a very important issue.
How can I reset the identity fields?
Thank you very much for your attention and help.

HiI've a tabel with two columns as identity fields (one as primary key), but I read in SQL 2000 documentation that it is permitted only one column as identity, it's true?The second field has to be autoincrement so I supposed to use identity field for it...Now the true problem, supposing that I can use two identity fields...I'd like to reset the second identity when the year change... In other words, I've to manage some spedition which are identified with XXX/year, where XXX is a number.Coming from Oracle, I supposed to use a trigger on insert which reset the sequence when the year changa, but in MS??Tnx...

I have a table that I need to add an identity field to. I created a field in the table as an INT and added values to all of the existing records. When I try to change it to an IDENTITY field I continually get an error saying 'Invalid cursor state' . The help function tells me that this is caused by not having enough space in the transaction log but I don't understand this b/c the trans log is configured to expand as needed. Anyone know how I can do this?
Thanks,
Tony

Most of the tables in my database are implemented with IDENTITY columns as the primary key.
When an INSERT from my application is attempted, sometimes I get an error returned stating that insert
cannot be done because of duplicate key value. If I try the INSERT again, sometimes it works(??). Of course,
DBCC CHECKIDENT resets the identity value if trying the INSERT again doesn't work. Then sometime a little later, the problem happens again.
Is there anything I can do other than placing into my application code the execution of dbcc checkident
anytime I want to do an insert to prevent the error? By the way, DBCC CHECKDB revealed no problems.
HELP!

Hello,
I am relativley new to SQL and have a question about identity fields.
I am creating a script to run everynight to insert records into a support table in a database. one of the fields is a identity field that is updated everytime a record is added locally or over the web.
Some records that are added into the database locally by users do not get added into theis support table, but so those new people entered in can use the website a entry must be added to this support table.
I am working on a script to take the records that where added by users and automatically put them in every night using a basic schedueled job.
The identy number is updated everynight in a table that collects all the important identiy numbers. I would like to use this table to alter the seed value and then increment by one every time a new record is added. This is my only sticking point so far.
Any help would be greatly appreciated.

Hi,
I am trying to replicate our application database (SQL server 2005) using transactional replication to another server. What I did was, took a backup of the live database and restored in backup server with same name. Then did a transactional replication. Issue is we have few tables having Identity columns defined as primary keys and 'Not for Replication' option of these tables is 'NO'. But once published, this becomes 'Yes' and also replication failed showing an error as
Explicit value must be specified for identity column in table <table name> either when IDENTITY_INSERT is set to ON or when a replication user is inserting into a NOT FOR REPLICATION identity column.
In the table article, for the parameter 'Action If name is in use', I have selected 'Drop the existing object and create a new one' (Also tried another option 'Delete Data'). How to resolve these issues.
Thanks in Advance,
Eldho Abraham

I have a table used by multiple applications. One column is an Identify field and is also used as a Primary key. What isare the best practices to use get the identity value returned after an INSERT made by my code.. I'm worried that if someone does an INSERT into the same table a "zillionth" of a second later than I did, that I could get their Identity value.
TIA,
Barkingdog

hi,
I've done Googling and forum hunting but haven't had success finding a simple answer... My table schema is such that it requires the (int) LinkedItemID field to be nullable but still those fields which are set must not be duplicates. I see constraint is out of question and also identity doesn't seem to fit since I'm not using autofill for this particular field. Is there some other way doing this on Sql Server 2005?
Thank you.

Hi, I'm trying to build a several tables using sql ce 3.1
I refer to the manual on Create Table:
ms-help://MS.SSCE.v31.EN/ssmprog3/html/143cad25-5c1d-4c96-bd8b-6a95dbfb1b00.htm
The sample:
CREATE TABLE MyCustomers (CustID int IDENTITY (100,1) PRIMARY KEY,
CompanyName nvarchar (50))
just simply doesn't work displaying this error:
SQL Execution Error
Executed statement: CREATE TABLE MyCustomers (CustID int IDENTITY (100,1) PRIMARY KEY,
CompanyName nvarchar (50))
Error Source: SQL Server Compact Edition ADO.Net Data Provider
Error Message: There was an error parsing the query. [Token line number =1,
Token line offset 40, Token in error=IDENTITY]
I tested against a SQL Desktop, everything is OK.
What's wrong with the sentence?
Please some advise or workaround will be appreciated
Thanks

Hi,I am always confused about what to use as the key for a table.Let's say I have a company-employee table.[company]---*[employee]My co-worker likes to use an AutoNumber or Counter as the key for the[employee] table (and everything).I personally use an actual key set for the [employee] table.So, his table will have one (Autonumber or LONG) column as the key. Thecompany_id is just another attribute.Mine, on the other hand, has 2 columns as the key. (i.e.) company_id +employee_idSo, what is the deal?--[color=blue]> There is no answer.> There has not been an answer.> There will not be an answer.> That IS the answer!> And I am screwed.> Deadline was due yesterday.>> There is no point to life.> THAT IS THE POINT.> And we are screwed.> We will run out of oil soon.[/color]

Hello friends,
I am using Sql Server 2005 in my web application. In one scenario I had made one field of a table as Autonumber by keeping its datatype as int and then setting its Identity flag to true. Now is there any inbuild function that can give us the next number tat will be generated if a new record will be inserted. This is needed in the case if last 1 or 2 records are deleted for e.g.
last record has value 7 and if the record is deleted still for the new record the number generated will be 8 i.e. after 6 there is 8. So by any means can we get the next number, or can we keep that autonumber to move serially even in case some record is deleted it should go for the max + 1 number.
Please let me know.
Thanks & RegardsGirish Nehte

Hi, I wish to build a datagrid, in an ASP.NET web page, in which I can display a row from a table and when I press a button it will move forward one row. The table is not currently sorted and I need it to be alpahbetical by surname so I thought if I created a view I could sort the table alphabetically on the 'Surname' column. I know that ADO.NET when used in disconnected mode doesn't have a cursor which remembers the last row it was on so I thought if I could create an autonumber on the view then I could use this in the 'where' clause to tell SQLserver which line I wished to select by taking the previous number and adding one. Is this the best way to do this and if so could some one give advice on how to write the line of the query that will add in an autonumber column
thanks
John

Hello all,
Has anyone heard about autonumber fields skipping one number? For example, the autonumber field goes from 39 to 41 skipping 40 entirely.
Any ideas why it would do this?
Thanks in advance.

hi,
i am thinking of using autonumber in my table which is more likely to grow over time. but i am also concerned that what if the records get too much? is there is any other fields to use instead of autonumber? is uniqueidentifier a better option? i have a bit of discussion with my colleague about this matter.
any help is appreciated
