I have an access table that has a primary key (entitled "ID Number"), no duplicates, the field is an integer.And, importantly, the value is set to "increment".The format is "phd"000 - so it starts out phd001, phd002, and so on...How to do this in an SQL table? Can that format be done? Or is it better not to do it via SQL but in coding instead?
View 1 RepliesHow 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?

Hi Guys,
I have designed a simple table named "test" with ID as primary key and Name as a string data. When I delete a row from the table and insert a new row.. then the ID column increments itself by 1..
for eg : if i have 2 rows in my table
1 Karthik
2 you
if I delete the 2nd row and insert your name in the place of 2nd row..
actually my rows shows
1 Karthik
3 yourname
could anybody give me some advices..

I am developing asp.net application with sql server database
I have table FinancialYear
caseno(unique) finyear
1 2013-2014
2 2013-2014
3 2013-2014
1 2012-2013
2 2012-2013
3 2012-2013
For financial year-2013 to 2014. if i insert record ( select max(caseno) +1).
insert into finanancialYear values(max(caseno) +1,2013-2014)
if i delete record caseno:3 from the table,
select max(caseno)+1 will be 3
Which is already deleted and again that record with caseno 3 will be inserted
For every financial year in 'FinancialYear' table,.caseno will be reset to 1
And if I add new record in finyear 2012-1013
then max(caseno) will be last value of caseno of that financial year 2012-2013
Again insert becomes
insert into finanancialYear values(max(caseno) +1,2012-2013)
I have given the data.
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? :(

Hi 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)

Hi all
I just got SQL server 2k5 installed and working....im just trying to figure out how to make an auto incremement column wiht an integer..
or has it been replaced with the "unique identifyer"
Abyss
I'm trying to create a column of numbers that increment by one.
I'm not able to use a #temptable in the application I'm using so I cannot use IDENTITY(int,1,1).
I want to add an Id column to this query:
Select distinct sd.name,ic.TABLE_SCHEMA,ic.TABLE_NAME from sys.databases sd
cross join INFORMATION_SCHEMA.COLUMNS ic
where sd.name = 'ODS1stage'
order by TABLE_SCHEMA,TABLE_NAME
How can I accomplish this without creating a temp table? I would just alter the table and insert the numbers but there are 2000 rows.
Hello,
I Have a table that needs to have 2 unique number.
detail_id and detail_print_id.
detail_id is already an IDENTITY.
both fields need to be different, because when importing, it imports the same data into a table twice, with only a slight data change (and id is not one of the changes).
So I thought i could do the following:
detail_id INT NOT NULL IDENTITY(1,2),
detail_print_id INT NOT NULL IDENTITY(2,2),
--blah blah
that way, the detail_id will always be odd, and the detail_print_id will always be even. however SQL Server 2005 only allows 1 identity per table, and both these fields need to be auto generated when the field is inserted, so as to prevent double data.
is there anyway I can create a int column to auto increment, without the column being an IDENTITY??
also, I would prefer to not have to create a second table with a single column just for this work.
Thanks,
Justin

Searching Help seems always to give primary KEY, but cannot be that at point of creating the DB.

I think there has to be a way to do this but I'm not seeing it.
I would like to set the names of my primary keys in the CREATE TABLE statements. I like this for documentation so it's very clear what the PK name is. When the system generates the key names, it always add the number suffix at the end. I would need to do this both when the PK is a single column and when it is multiple columsn (see examples below).
Thanks very much for your assistance.

Hi, I'm in the midst of an Access 2003 to SQL server 2000 upsizing project and have come across a table on Sql Server that has a field that looks like it's supposed to be the PK but it contains duplicates. What I'd like to do is to have a cursor start at the first value and increment the next value by 1. Could someone explain how I'd go about this?
Many thanks,

I am trying to create a FK using a composite PK and here are the details that I want to achieve.
Table -A
Column A1 not null,
Column A2 not null
Primary key (A1, A2).
Table -B
Column B1 Primary key.
Column B2 not null
FK (B2) References A(A1).
When I try to do this I am getting some errors. Questions: First of all is this possible? if yes, then how I can create it.
In what situations we can create primary key on a table? I mean what is the minimum no of rows we can prefer to create PK.

Jon Galloway provided a sample in http://weblogs.asp.net/jgalloway/archive/2008/01.aspx but the Primary Key Field and Primary Key Value were inserted into separate columns while I need to combine the Primary Key Field and Primary Key Value into 1 single field, using his example, I want to form the primary key as:
ScoreId = 423
ScoreId = 3064

Note that his example only show a single primary key in a table whereas I need to handle multiple primary keys in a table.
I have two practice tables I have created and want to export the values of one into the source table. I want to know if I can export into a table and have the destination table automatically give a primary key value to a record? I haven't been able to figure this out even after fiddling with the "Enable identity insert" checkbox under the Column Mappings tab. I have created source tables with and without primary keys and neither works because of the fact that I need to have a value for a primary key in order to INSERT into the destination.
Do I have to copy the source records into a staging table and assign the PK values myself by hand? This can't be the answer.

This is for SQL2k5. The database may be small or big, I don't know (it's going out to multiple customers). I'm wondering if in general it's considered "better" to create a single non-primary default filegroup and put all the objects there, or just leave everything in primary? In one training years back I got the impression that recovering the primary filegroup was important for certain restore operations, so it was always wise to separate them like this.
Thanks for your input,

Hi All
I hope someone smart can help me, it would be highly appriciated.
I am developing an SQL Serverdatabase and in on of the tables I need the primary key to consist of two pieces of data.
TblOrders: OrderNum, Orderdate, ....
TblDispatchers: DispatcerID, Dispatcher, DispatcherAddress
The OrderNum field in TblOrders need to be a composite of an AutoNum-field (incrementet by 1) and the DispatcerID from the tblDispatchers.
Can this be done, and how.
Many thanks
