If delete all the records from a table that has an incremental identity. Is there a TSQL way of reset the first number on an insert back to be 1 again without going to the table taking it off then saving it the putting it back on again?
View 2 RepliesHello!
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

Hello, I need some help writing a script to generate Identity keys. I cannot use the row number generator because I would like to start the identity at a package level variable. Is this possible?
Thank you in advance

View 4 Replies View RelatedIam 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
View 2 Replies View RelatedI 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!

Hi, for some reason I want to have a unique ID with a seed and random Identity increment (I want an ascending ID's but without able to know how many objects there are).
any ideas?
thanks in advance
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
just gives error at IDENTITY
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,

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!
Dear Sir,
the following code is copied from the SQL Server Help Example.
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.
Msg 156, Level 15, State 1, Line 3
Incorrect syntax near the keyword 'IDENTITY'
Can U please guide me abt the error.
with regards,
wilfi
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 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

I am looking to make the primary key auto increment by 1. I have found by looking around the internet that you need to do this in the Tables -> [Table Name] -> Columns -> [Column Name], Properties window, and I see the "Identity Increment" however all of the properties there are greyed out -- I can't access them. Any ideas on how to make this work?For some background: I'm running SQL Server 2005 with Visual Studio 2005. To create this database, I right-clicked on my project, and went to 'Add SQL Database', I filled in the columns all from within visual studio.
View 1 Replies View RelatedI have an MS SQL Server table with a Job Number field I need this field to start at a certain number then auto increment from there. Is there a way to do this programatically or within MSDE?

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
While I have learned a lot from this thread I am still basically confused about the issues involved.
.I wanted to INSERT a record in a parent table, get the Identity back and use it in a child table. Seems simple.
To my knowledge, mine would be the only process running that would update these tables. I was told that there is no guarantee, because the OLEDB provider could write the second destination row before the first, that the proper parent-child relationship would be generated as expected. It was recommended that I create my own variable in memory to hold the Identity value and use that in my SSIS package.
1. A simple example SSIS .dts example illustrating the approach of using a variable for identity would be helpful.
2. Suppose I actually had two processes updating these tables, running at the same time. Then it seems the "variable" method will also have its problems. Is there a final solution other than locking the tables involved prior to updating them or doing something crazy like using a GUID for the primary key!
3. We have done the type of parent-child inserts I originally described from t-sql for years without any apparent problems. (Maybe we were just lucky.) Is the entire issue simply a t-sql one or does SSIS add a layer of complexity beyond t-sql that needs to be addressed?
TIA,

I want to insert a new record into a table with an Identity field and return the new Identify field value back to the data stream (for later insertion as a foreign key in another table).
What is the most direct way to do this in SSIS?
TIA,
barkingdog
P.S. Or should I pass the identity value back in a variable and not make it part of the data stream?
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?
Ok,I just need to know how to get the last record inserted by the highestIDENTITY number. Even if the computer was rebooted and it was twoweeks ago. (Does not have to do with the session).Any help is appreciated.Thanks,Trint

I am having problem in bulk update of a sql server table haning identity column from a datatable( has no identity column) using sqlbulkcopy. I tried several approaches, but it does not show any error nor is the table getting updated. But the identity value seems to getting increased every time.

I'm working with a third-party database (SQL Server 2005) and the problem here is the following:
- There are a bunch of ETL processes that needs to insert rows on a table (let's call this table T) and at the same time, an ERP (owner of T) is up and running (reading, updating and inserting on T).
- The PK of T is an Integer.
Today all ETL processes uses (select max(ID) + 1 from T) to insert new rows, so just picture the scenario. It is a mess! Everyday they get duplicate key error when 2 or more concurrent processes are trying to insert a row (with the max) at the same time.
Considering that I can't change the PK, what is the best approach to solve this problem?
To sum up:
* I need to have processes in parallel inserting on T
* I can't change anything on T
* The PK is NOT an Identity

I'm using SQL Server 2000 with MS Management Studio. I have a table that has 400 rows. I have setup the Primary key to increment automatically. How do I setup so that the next record starts at 4001 and up? Right now it starts at 1274, for example. So besides dropping the table and re-creating it, how do reset it so it counts from sequentially from the last row inserted?
