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. The
company_id is just another attribute.
Mine, on the other hand, has 2 columns as the key. (i.e.) company_id +
employee_id
So, what is the deal?

I am working with a database that was created in Lotus and importingit into Access. There are hundreds of clients in this data base thathave to be kept and maintained. My question is: Will auto numberingwork with this imported file and will it continue with the last numberthat is in there and if not can I make it work and how?

The problem is to set the right type for "Question_number"/"test_str"I have tried Integer & String (Long Integer din't work....) The field: Question_number is autonumber dim test_str as Integerdim besvart_str as string answer_str = "Yes" Date_now = nowtest_str = 187 Dim StrSQL_2 as String = "UPDATE q_a_table" & _ " SET answer = '" & answer_str & "' WHERE [q_a_table].Question_number= '" & test_str & "'"
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
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.
i am using autonumber as a primary key in one table. in my app., row from that table will be moved to another table after some time but that autonumber is important. when there are no any data in first table, and new row is inserted, autonumber starts from 1 which i don't want as there will be data redundancy when it will be moved to another table. so is there any way i can force the autonumber to start from previous value rathe than 1?
Hello, Does anyone know if there is an equivalent of an autonumber in SQL Server. I have tried to use the int field which I thought preformed the same function but it doesn't work for me. The code I am using is as follows aCommand.CommandText = "INSERT INTO customers (customer_Name, customer_Id) " + "VALUES (@customer_Name, @customer_Id)"; aCommand.Parameters.Add("@customer_Name", SqlDbType.NVarChar, 50).Value = TextBox1.Text; aCommand.Parameters.Add("@customer_No", SqlDbType.Int, 4).Value = SqlDbType.Int;
However, when I try this my customer Id is not unique., and my cusomer_Id is always set to to the number 8. Does anyone know a way around this?
Hi, I have a question, I have created a table and with a primary key called "ID".

Is it possible to make a AUTONUMBER field in an SQL table?Microsoft Access allows you to create an auto generate field. If possible, please enlighten me.THANK YOU
What is the equivalent to autonumber in SQL 7? I ported over some data into SQL but when I bring it up in Access 97 as linked tables it shows that what used to be autonumber in Access is listed only as number in SQL. So what is the equivalent to Autonumber in SQL?
I have been working with Sql Server 7 for about 5 months now, so I am relatively new when it comes to understanding the migration process from Access 97 to SQL. I have run into one particular problem to which I have not accurately found the solution. The Access database that I work with involves using the autonumber field. This number in Access is generated when the form is opened, thus allowing me to open another form that references that first auto-generated number from the first form. My problem stems from the fact that Sql doesn't generate this autonumber until the form is saved. This cause a problem because the comment information needs to be saved with that particular entery. I need to know how do I deal with this particular problem of generating an autonumber when the form opens.
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?
Hello, i am creating tables in SQL Server 2000 using the Enterprise Manager. I want to set my Key field as a autonumber field (like in Access) so it will automatically generate a ID # for me. Is there any way to do so through the Enterprise Manager? And if not, is there any other way? Thanks,
I have converted our db over to SQL 2000 from ACCESS, and our tables to be autonumbered, can't find that feature or option in SQL2000. Would really appreciate any help from this group.

Hi everyone. I am trying to build forms that when users fill out the form it will create an PK that has a naming convention of the year, project, and the number of the request from that project. Is this possible? One of the fields on the form is a drop down that would have the project number listed in it so it would give them the option to pick project number - i want it to look like so -
yy-2329-001 date - project number pulled from drop down - number of requests auto numbered for this project
anyone have any ideas on how to do this. I am using coldfusion if anyone needs code to help with that. I am not sure if I have to do this in coldfusion or in MS SQL. thanks.
Does anyone know how to reset an autonumber field in SQLExpress 2005?
In MSAccess it was a simple "compress" of the database. My .mdf files are getting very large and I would like to shrink them down for easier mobility. A blank database takes up aprox. 30 mbs. Most all of the autonumber fields are currently in the 200,000 - 800,000 range. When I compressed my Access database prior to transfering to SQLExpress it significantly decreased the size of the empty database file.
So far, I have only used Access which has an autonumber data type so that in some of my tables the id is automatically generated. I guess this is a simple question but is there an equivalent data type in sql server?
