Access To SQL Conversion - Autonumber To Identity Fields
Nov 22, 2001
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????

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?

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

Is there an equivalent in sql server2005 to msaccess autonumber?
I want to be able to insert values into a table and have the pk auto generated. Have tried using NEWID() function as default value for pk field but still have to stipulate NEWID() in the insert statement.
Is there a way around this?

what can we do if we have to get the next autonumber to be inserted {before inserting the record} in MS access
It is a simple think to get the max(id) + 1.But if tere is some record deleted then this will not work correctly
for instance i have records
id Employeename
11 a
23 b
31 c
45 d
then if delete 31 and 45 my record becomes
id Employeename
11 a
23 b
now when i get max(id) +1 it will return 24 {rather then 46 which i want's to retrieve}
Is there any way that i can get the next autonumber to be inserted prior to insertion of the record ?
{Although it is questions is not particular to sql server but i think some geek might answer it here}

Hi,
I have developed a web database application using ASP and MS Access, however the requirement for hosting the application is that it must use an MS SQL Server database. I converted the database to SQL without any problems, and many features of the application work under SQL Server except the 'add record' function. I realised there isn't an 'autonumber' field in SQL Server (which i use as the primary key for many tables), but an 'int' field. I considered pulling out the latest int from the database, incrementing it manually and adding the new record with this number... i also noticed there is a 'unique identifier' field.
Is there a quick solution for this problem?
Thanks

I am building a simple table, populated by ASP form, where every record should be assigned a unique ID. When working with Access I used `autonumber` datatype to keep track of every record. Can something like this be done with MS SQL server, if not what do you think is a good way to solve the problem ??
Thanks,
Robert :)

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,

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

I hope that some one can find the time to advise an uninitiate. I have built a fairly complex data base system using Access 97 that handles many of my company's day to day operations. I does most of what I want although lately I have found that it has become pretty slow. This could be due to the fact that this is really my first big project and perhaps I could be a bit sleeker with my coding. It could also be due to weaknesses in my network. Finally it could be due to weaknesses in Access. I was wondering if there was any one who might be able to shed a little light on what steps I would take that would be the most likely to speed things up.
I realize this is a pretty general question but I would be eager to provide more detials. Any guidance in this matter would be apreciated since I have a bit of money and am planning a LAN upgrade anyway. Perhaps I should save a bit of money on the LAN and put it into a copy of SQL Server?
Thanks

Hello, I'm trying to convert a Access DB to a SQL 7 DB, problem is that there are a LOT of of make table queries, and some of these tables use the aggregate function First() when doing the GROUP BY, I know SQL7 doesn't support first, but is there another way to "fake" this FIRST?

I am brand new to SQL server.
I just installed it in fact. I am running version 6.5.
Got it configured and seems to be running fine..
Now, I need to know how to convert my MS Access database to use SQL server.
SQL seems more complicated than Access, so I need some guiedance.
Can anyone give me some info on Access to SQL conversion or at least point me in the direction as to where I can get this information?
Appreciated.

Hey--
I've been developing an application that will function as an online organization-specific contacts directory for my employer. The interface is coded with ASP and the data is stored using an MS SQL Server 2000 database.
I've completed the coding for the front side of the application and the design and testing of the database itself, so I'm now at the important state
of migrating existing data into the new database.
My problem is this:
For the large part, our organization stores its contact data in MS Outlook 2002. This is easily exported to an Access 2002 database, which I have already done for a number of our employees.
I need a way to take the data found in each of these Access databases and insert it into my new MS SQL 2K database. I am aware that an upsizing wizard exists, but the only version I can find is for Access 97 to SQL Server 7 conversions. Beyond that, I don't want to create a whole new database: I simply want to migrate the data I need from the Access files into the schema developed around the new application.
Help is desperately needed and much appreciated.
Thanks!

Hi Everyone,
To start off, can I just say that I know very little about SQL databases but I have a MS access database which we are outgrowing and I think we will need to make some changes. I was wondering if some one could offer some advice. There are many programs available for upsizing to SQL but I presume these are for the back end only, is this correct? Is upsizing a bad idea or a very difficult one?
I was also wondering about keeping my Access front end and connecting it to a SQL back end, is this a good idea?
Any alternative suggestions would be appreciated.
Regards
Nora.

I'm trying to convert an Access Query to SQL. I am using a "Mid Statement" to select a portion of a value:
Mid([ITEM_NUMBER],2,7)
When I try to parse this statement in SQL I always get an error "Does not recognize Mid as a valid procedure."
Is there an SQL statement I could use to accomplish this?

Works good in access, but when trying to put it un sql server, it comes up with errors.
I know mid is substring, I just don't know what trim and instr are in mssql.

Hi there, apologies if i have entered this into the wrong forum.
I am currently building an application using microsoft access and coding in VBA (what i can!)
When i have got it working as i like after user testing i would like to create an MDE file to distribute to users and i would like to convert the access database held on a file server to a SQL server but have no experience of doing this.
In what order would i do this and would i suffer a loss of functionality in changing from access to SQL i.e. would some of the VBA code not work in SQL?
Thanks for your time,
Rhys.

Hi there,I have written an application which uses MS Access for it's database engine.Due to the large size which the database has become I have decided that itwould be sensible to use SQL Server with the application instead.I am an extreme SQL Server newbie so I am not really sure what I'm doingyet! I have successfully downloaded and installed the MS SQLDE 2000 andservice pack 3.What do I need to do next? Ideally I would like to convert the existingAccess database to MS SQL Server format. Also I would like to know if it ispossible to create an SQL Server database from scratch using a guienvironment similar to Access and if so which software (preferably free) doI need to achieve this?Many thanks,Clive.
