Hi. After inserting data (new row) by using DetailsView control, how to read auto incremented primary key (identity) of this new row from sql database to use it as parameter passed to stored procedure?
View 4 RepliesI have a sql sever 2005 express table with an automatically incremented primary key field. I use a Detailsview to insert new records and on the Detailsview itemInserted event, i send out automated notification emails.
I then received two automated emails(indicating two records have been inserted) but looking at the database, the records are not there. Whats confusing me is that even the tables primary key field had been incremented by two, an indication that indeed the two records should actually be in table. Recovering these records is not abig deal because i can re-enter them but iam wondering what the possible cause is. How come the id field was even incremented and the records are not there yet iam 100% sure no one deleted them. Its only me who can delete a record.
And then how come i insert new records now and they are all there in the database but now with two id numbers for those missing records skipped. Its not crucial data but for my learning, i feel i deserve understanding why it happened because next time, it might be costly.
Hi,
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.

Hello,
I have a column that is not auto-incremented. I would like to make it auto-incremented. For the moment, the only solution I found is to delete my column and to add a new auto-incremented column. The problem is I cannot delete it without deleting dependencies on it... So is there a solution to make an existing column auto-incremented or is it necessary to a create a new column ?
Thank you in advance for your help.
I am trying to insert into a SQL Server table from an Oracle database. This table has an auto-incremented field, and when I try to insert into this table I get the following error:
Code Snippet
[Microsoft][ODBC SQL Server Driver][SQL Server]Cannot insert the value NULL
into column '<column_name>', table '<my_table>'; column does not allow nulls.
UPDATE fails.[Microsoft][ODBC SQL Server Driver][SQL Server]The statement has
been terminated. (SQL State: 23000; SQL Code: 515)
When I turn off all the triggers in the database, I don't get this error. But that is just a test environment, the production environment will need to have those triggers activated.
Any ideas on what is going on here?
Thanks.
Good day gentleman,
Is it possible to pad columns of Int data type with zeros?
I currently have a primary key column of data type Int which is auto-incremented by 1. My problem is I need to pad the auto-incremented ID's with ten zeros so, 0000000009 instead of 9.
I can pad the ID's in the c# dataaccess layer, but i need to generate/store them padded in the database to allow direct reporting.
I am using Enterprise Manager and i can see a Formula field when the table is in design view, can i use this? i am just guessing here.
Any comments or pointers would be a big help.
I want to assign consecutive numbers to a block of data, where block of data is based on days consecutive to each other i.e., one day apart.

Ok I know this might not be the most accurate place to post this but I know someone here has an answer for me on it.I need to get the product_ID of the new record that is created by this insert statement INSERTINTO products ( class_ID,category_ID,product_name,product_desc,product_image,product_dimension,product_o1,product_o2,product_o3,product_ac,product_ph,product_photo ) SELECT class_ID,category_ID,product_name,product_desc,product_image,product_dimension,product_o1,product_o2,product_o3,product_ac,product_ph,product_photo FROM productsWHERE product_ID = @productID
View 2 Replies View RelatedHi,
I would like to know how I can retrieve the ID (Primary key) of the row I just inserted with a sqlcommand(text not stored procedure).
Thx
I need to insert a row of data and return the value of the primary key id of the row.
I thought that something like this would work
int Key = (int)command.ExecuteScalar();
where command is SqlCommand object.
It doesn't work, maybe I've misunderstood the usage of ExecuteScalar.
Not sure if this is the right place for this post or not, but I'll give it a try...
If I am inserting a record into a table that uses a Primary Key, but not an Identity column, how do I insert the new primary key value? I started out with SQL just letting the Identity column increment itself for primary keys, but I cannot do that for this particular situation.
If 'AddressID' is the primary key in the 'Address' table, could I do something like this:
INSERT INTO Address (AddressID, Field1, Field2, ...)
VALUES (**max value of primary key in Address table, plus 1**, 'field1data', 'field2data', ...);
If that works, how would I make this part of the insert query:
**max value of primary key in Address table, plus 1** ?
I hope this question is clear and makes sense. If it's not, please let me know.
Ok, this is a really stupid question, but I can't seem to find an answer I understand. In my SQL database I have a a table called MasterSkillList, to which the user can write by using a little web form with a text box and a drop down list. The table has 2 fields, Skill and Attribute. Skill is the primary key, as no skill can appear twice. What I want to do is prevent just that, I don't want people to enter the same skill more than once. So how do I tell the user that the entry allready exists in the database?
My C# Code is as follows:1 protected void btnSubmit_Click(object sender, EventArgs e)
2 {
3 srcAddSkill.InsertParameters["Skill"].DefaultValue = txtSkillName.Text;
4 srcAddSkill.InsertParameters["Attribute"].DefaultValue = ddlAbility.SelectedValue;
5 try
6 {
7 srcAddSkill.Insert();
8 lblErrorMessage.Text = "The skill '" + txtSkillName.Text + "' has been added. It is based on a character's " + ddlAbility.SelectedItem + " score.";
9 lblErrorMessage.Visible = true;
10 txtSkillName.Text = "";
11 }
12 catch (Exception ex)
13 {
14 lblErrorMessage.Text = "An exception has occurred. " + ex.Message;
15 lblErrorMessage.Visible = true;
16 }
How 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?
Thanks
I discovered the cause:
in SQL Server Enterprise Manager, open up db tree, right click the table, go - 'design' and set 'Identity' to yes.
I 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));
I 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.

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? :(

I'm still looking for a solution on msdn, but i've decided also to post my question here.
How can i reset my primary key field auto-increment back to 0 in runtime (or in designtime)?
The table I am using have a column called Key which is the primary key of the table and a auto number. This primary key is not a foreign key in any other table.
I need to write SQL to drop the current primary key and add a new one Say "RecordId"
as the new primary key and which should be a autonumber too.
any idea.
thanks in advance
Hey 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 :)
View 9 Replies View RelatedWe have upgraded our SQL 2008 server to 2012 last month. i've noted since then that many tables that have auto increment primary key bigint field increases by 1 like it should, then for some reason it jumps up by 1000 or even 10000? i have seed adn auto increment set to 1 but doesnt effect it. Is there anything that could be causing the next value to jump that much?
View 18 Replies View Relatedhi guys,
just a question regarding database design
i have a table with an auto-generated primary key but the problem is this:
say i have 4 records,so logically they'll be numbered 1 to 4.so the problem is whenever i delete all records and add new ones,the numbering will start from 5 and not 1 again.
how do i remedy this?
thanx
How would i get the value of a field that i just inserted and put that into a parameter, so that i could update another table.
This is the code that i used in the trigger that did not work:
@field1 = select srcfield1 from inserted
Anyway here is the full code:
CREATE TABLE Source (srcID int IDENTITY, srcField1 nvarchar(50))
CREATE TABLE Destination (destID int IDENTITY, destField1 nvarchar(50))
go
CREATE TRIGGER tr_SourceInsert ON [dbo].[Source]
FOR INSERT
@Field nvarchar(50) output
AS
SELECT @Field1 = SELECT Field1 FROM inserted
UPDATE Destination
SET Field1 = @Field
where destID = '1'
go
INSERT Source(srcfield1) VALUES ('A')
go
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)
2 {
3 //cannot have the same device entered twice!
4 if (Adapter.FillDeviceCountByMakeModel(make, model) == 1)
5 return false;
6
7 RepositoryDataSet.DevicesDataTable devices = new RepositoryDataSet.DevicesDataTable();
8 RepositoryDataSet.DevicesRow device = devices.NewDevicesRow();
9
10 device.make = make;
11 device.model = model;
12
13 devices.AddDevicesRow(device); << Error thrown Here!
14 int rows_affected = Adapter.Update(devices);
15
16 return rows_affected == 1;

I 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)?
I have imported a whole bunch of tables. Most of them have an ID (int) column. Is there a way to set the ID columns across all tables to auto increment Primary Keys in bulk?
