Auto Incremented Integer Primary Keys Vs Varchar Primary Keys
Aug 13, 2007Hi,
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.
Regards

Dec 21, 2007Hi 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.

Apr 13, 2008Dear 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.

Primary Key-how To Auto Incriment
Jun 8, 2007I 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));
Auto Primary Key With Fill In
Jan 26, 2007I 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.
How To Auto Increment A Primary ID Field?
Oct 8, 2006I 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.

Apr 26, 2007Ok - 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? :(
Aug 6, 2007How 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? :(

Redefining An Auto-generated Primary Key Constraint Name
Jan 9, 2007Hey 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 :)

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?

SQL 2012 :: Auto ID Primary Key Specified As Int And Table Data Is Deleted Periodically?
Jun 25, 2015I 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)?

Return The Generated Primary Key
Mar 28, 2008
Dear all,
I would like to use SSIS to populate product information from a remote database to a local one.
There are Product table (which contains the basic information) and ProductImage table(which contains the product images in binary).
I would like to use a join query
SELECT A.name, A.price, B.image from Product A INNER JOIN ProductImage B WHERE A.ProductImageID = B.ProductImageID
to return all the product information from the remote database.
When populating the local database, the local ProductImage table will be populated first and then the local Product table will be populated with the ProductName, ProductPrice return from the query together with the newly genetated ProductImageID afer insert a record into the local productimage table.
The ProductImageID column is set as the identity column in the ProductImage table.
I am very new to SSIS. Is there a way to handle this scenario? What components do I need to use?
Thanks

GROUP BY Min Price BUT Return Primary Key Of Row
Oct 24, 2013I have a table with multiple products from different suppliers. there will duplicate products in my db as Supplier A may stock the same product as Supplier B. I have a business rule that only one unique product can be online at one time and as such I want the cheapest product from the 2 Suppliers to be displayed where there is a match.
I have been trying a Group By clause and also a partition by but my problem is returning the primary key for the winning row (minimum price).
here is an example
CREATE TABLE #TempTable(
productcode nvarchar(50),
productname varchar(50),
productmanufacturer varchar(50),
saleprice money,
tyrewidth varchar(5),
[Code] ....
How can I return the productcode in the above query for the row with the cheapest price? If I try MIN(productcode) or MAX(productcode) it will not always return the product code associated to the min price.

I am making a program in Visual Basic .NET with SQL Server 2000.
I have a table "MyTable" with a primary key named "Id". The primary key is 'Create Unique' checked and 'Index' selected. When I insert all the fields required, except "Id" of course, I need the new record's "Id" in my VisualBasic program, but I don't know how...
I must do one of them, but don't know how either of them:
-Create a trigger on insertion that will send to the user that sended the insert command the "Id" of the record just created.
or
-get the command in Visual Basic that will send the Insert command with a return field ("Id")
