Problem With Identity Column Increment In Sql Server 2005
Jan 22, 2008
Hi
I am trying to use the identity data type ( column)
I am using examples from the book and management studio in sql server 2005.
I am using the identity property for the customer Id in customers table.I accidentatly executed the querry twice and I had two same record with different customer id numbers of 1 and 2 . I realised the problem and I had to delete the second record.
The problem is now even if I have deteted the 2nd record with customer id 2 , when I insert a new record the identity value ( customer Id) increments with a number after the value I deleted. i.e if I deleted a second row with customer id 2 ( identity 2) when I enter a new record it enters with a customer id of 3 and whenever i add a new record it increments from there.
So instead of first record have cust id 1 and second record customer id 2 etc , I get first record with cust id 1 , second record with cust id 3 , third record cust id 4 etc.
How can I get rid of this wrong values of identity values whenever I delete a record and try to add a new record?
Thanks

I have created a table that generates a sequential id and a
stored procedure that will return that id. The trouble is
no matter what I set the Seed or Increment values to, the
id will always start with #1 and increment by 1.
My table is BILLING_TIME_ID
Identity field BT_GEN_ID
(SEED 200, INCREMENT 1)
The sp is as follows:
CREATE PROCEDURE BT_NEXT_ID
AS
INSERT dbo.BILLING_TIME_ID DEFAULT VALUES
select count (*) from dbo.BILLING_TIME_ID
GO
I have double checked that Identity_Insert is set to off for
this table. (does this default to off unless it is set to on?) Since
there is only 1 field in the table, I don`t have any indexes set.
Thanks for your help!

trying to change a column that is just a INT NOT NULL column, to have an auto-increment.
Code:
ALTER TABLE [ImpExpTables].[dbo].[ImpExp_eBayLocalNeedsDeleted]
ALTER COLUMN ID int IDENTITY(1,1) NOT NULL

Hi,
How to Change Increment Value for existing Identity Column (MS SQL2000) ?
I know how to change the seed :
DBCC CHECKIDENT (activity, RESEED,4233596)
but I need the future id generated with step 2
4233596
4233598
4233600
I would like to do it using T-sql because I will need to do it every day after syncronising with another SQL server .
Thanks,
Natalia

CREATE TABLE MyCustomers2 (CustID INTEGER IDENTITY (100,1) PRIMARY KEY, CompanyName NvarChar (50))
INSERT INTO MyCustomers2 (CompanyName) VALUES ('A. Datum Corporation')
ALTER TABLE MyCustomers2 ALTER COLUMN CustId IDENTITY (200, 2)
It gives the following error.

Hello!
I is true that SQL-Server use lower values than last integer value (in auto incremet field). Is there option that i could prevent that. So the Server would always put + 1 for the auto increment value.
Thanks

Iam trying to add a column to an existing table that would be an "identifier". I called it "ReadingNumber" and selected Identity "Yes" and "Identity increment" as 1.
When I add it, it just gives the rows random numbers instead of by the order they were inserted into the database by.....is there a way to autonumber the columns correctly? I have a COLUMN called Date and also one called Time that have the date and Time, but the format is char.
Would I have to convert the date time columns into something SQL understands, sort them ASC or DESC and then do the Identity column add?
Thanks for any help

Reset the Identity IncrementHello:I have a table with a bigint type column (field) that has an identity seedof 1 and an identity increment of 1. The column is the primary key for thetable.After I backup and clean out the database (delete all of the data in the DB)I need to have the column with the identiy seed/increment value reset to 1automatically. (start counting at 1 again). How does one do that, becauseas it is now, the DB keeps increasing the value of the column from where itleft off, regardless of the fact that I deleted all of the data in thetable.The DB is MS SQL Server 2000.Thanks and appreciate any help.Ryan Kennedy

Hi all,
I've been thrown a curve ball late in the game on an application I'm developing. Without getting into the specifics of the application I store a unique employee ID number for all person records in it. This ID is provided to us by the companies we're servicing. Up until this point in time we didn't have need of an externally visable ID other than the one provided to us. Now, a need for an internally generated (by our application) unique ID has been discovered. This number needs to be a minimum 5 digits (e.x. 10001, 10002, ....). I could achieve this nicely by seeding an identity column at 10000 with an increment of 1. However, I've alredy made different settings for this and there are records in the db with the old ones.
My question is: If I initially set the seed / increment at 1/1 can I change this after the fact without causing data integrity problems. Will all subsequent insertions into this table just start at the new values?
Or, ideally I'd like to create a new column seperate from the PK Identity column already in place that serves the same function, incrementing a 5 digit number by 1 for each new record. Seems that you're only allowed one identity column per table though. Is there another way to achieve get the same result as identity?
Thanks!

I had a strange problem today with one of the identity fields in a frequently used table. It appears that the Identity column for a table had stopped incrementing after it reached 2147483585. Since I had inherited this table, I am not sure if the identity column type has been modified from int to numeric, but the current type is Numeric (9) which is 19 precision and 0 scale value.
When resetting the seed to 1, it started working. I tried creating a temp table with numeric value and it increments well beyond billions with no problems.
Has anyone encountered this? Any best practices around defining Identity data type (ie. use int or bigint and avoide Numeric)?
Thanks

Hi,
I add new records to a table with ADO. The tables contain an auto-increment identity column. I want to retrieve the identity value after the insert operation. This works fine for SQL Server 2000. On SQL Server 2005 this only works if I use a table in the select statement. If I use a view in the select statement, ADO returns no value for the identity column, a trace with profiler shows that there is no Select @@IDENTITY statement.
What is the reason for this behavior?
How can I change this behavior in SQL 2005 so that the behavior is the same as in SQL Server 2000?
Best regards,
George

I have table of three column first column is an ID column. However at creation of the table i have not set this column to auto increment. Then i have copied 50 rows in another table to this table then set the ID column values to zero.
Now I have changed the ID column to auto increment seed=1 increment=1 but the problem is i couldn't figure out how to update this ID column with zero value set to each row with this auto increment values so the ID column would have values from 1-50. Is there a away to do this?

I have two tables having one row identifier column each of int datatype. Both these columns are part of the respective primary keys. Now as a part of my process, i'm inserting one small part of data from one table to another table. This was working fine but suddenly started getting error like
Violation of PRIMARY KEY constraint 'PK_TargetTable'. Cannot insert duplicate key in object 'DW.TargetTable'. The duplicate key value is (58544748).First I checked with DBCC CHECKIDENT with NORESEED and found that there is difference in the current identity value and current column value. I fixed it by running DBCC CHECKIDENT. But to my surprise again got the same issue. interesting thing is that the error comes after inserting 65466 records.

Is there a way to reseed the Identity column in SQL Server Compact Edition? The following command does not appear to work DBCC CHECKIDENT (Table_Name, RESEED, 0) and I cannot seem to TRUNCATE the table either. Not sure if table truncation is even supported.

Hi, All:Please help. I use sql server as back end and Access 2003 as front end(everything is DAO).A table on SQL server has an identity column as the key.We have trouble on adding records to this table using the following SQL.strSQL = "INSERT INTO myTableOnSQLServer (A, B, C, D, E) SELECT A, B, C, D,E FROM myTableonAccessLocal"db.execute strSQLThe schema of the table "myTableOnSQLServer" and the schema of the table"myTableonAccessLocal" are all the same except that the "myTableOnSQLServer"has an identity column (ID). The key of the "myTableOnSQLServer" is "ID" andthe table "myTableonAccessLocal" does not have a key.When we try to run the query, it gives errors indicating the key is violatedor missing.Should I figure out the autonumber for it first and then add to the SQLserver table?Many thanks,HS
