SQL 2012 :: Seed Value Of Identity Columns Jumps / Gaps By 1000 After Restarting It?
Jan 9, 2015
We just switched from Sql server 2008R2 to Sql server 2012.I am facing one problem with identity Columns "When ever i restarts my sql server,the seed value for each identity column is increased by 1000 (For int identity column it is 1000 and for big int it is 10000).
"For Example if seed value of any table was 3 then after restarting sql server will be 1003 if i again restart sql server it will be 2003 and so on."
After searching on google i found that it is a new feature (don't know what is use of it) in sql server 2012 and having only two solution if you want old identity concept
1. Use sequence object -
a) I am using same database in sql server 2008 and 2012 both so can't use sequence in 2008.
b) if i go with sequence then need not change save procedure for each table,which is bulky task for us.
2. Use Trace Flag 272 (-T272)
I can go with this solution because there is need not do any changes in my application.Some one suggested me that add -T272 in startup parameter,after this sql server identity column will work normal as previous version.I did the same but it is not working.
I don't want to do any changes in my database structure.
how to use this -T272 or why it is not working.
I don't want to use this new identity feature how to suppress it. Why -T272 is not working.

Create a table with an Identity column, insert data / restart the server / insert more data / restart the server/ insert some more data.
My data looks like this :
Identity column
1
2
3
1002
1003
1004
1005
2002
2004
It looks like the indentity value gain +~1000 after most server restart (sometimes identity stay the same). This can be very dangerous for some datatype! The only thing google told me was this : URL...but microsoft did not comment on it yet!

The identity int column in my sql2012 db is not incrementing properly.
I have a table which uses an int auto identity as a primary key it is sporadically skipping increments, for example:
1, 2, 3, 4, 5, 1004, 1005
This is happening on a random number of tables at very random times...

After SQL server service restart, a column which is set to auto increment jumped 1000. To fix the issue, I had to add T272 trace flag to SQL startup parameters. However, I did not see the column being reseeded after the service restart, it is still showing the 1000 jump. Am I doing something wrong?
Below the log showing the flag being added to the error log:
LogDateProcessorInfoErrorMSG
2015-06-15 22:29:53.850ServerRegistry startup parameters:
-d E:DATAmaster.mdf
-e E:logERRORLOG
-l E:DATAmastlog.ldf
-T 272

Hello-
I am auto generating an id when a record is input into my database.
I know how to set the id field to create an identity seed for each new entry with an increment of 1.
Is there anyway to add characters to begining of this identity seed. Can it only be an integer.
For example I would like my id field to be in the following format:
NCID - 1
NCID - 2
.
.
.
.
Can anyone show me how to do this if possible?
Thanks

I have a table with an identity seed in it. I need to go back and get some history that wasn't loaded into it. I would then like to resequence the identity column. Is this possible? Can I use the dbcc checkident? or will this just start any future inserts with the number I specify. I would like to reseed the whole file when I'm done starting with 1 and going forward is this possible with this command.

How can i reset the identity seed of a counter field to 1 after deleting
records from a table. Even though the identity seed displays 1 in the design
mode, when i add another record the counter field is incremented to the next
number from the last deleted record.
thanks

Hi,
I have a table with an identity column..How will the identity gaps be adjusted if i delete few records in the table..ie..the sequence should automatically adjusted..Is there any way for this ?
ID Name City
1 abc xyz
2 mexm mcel
3 olekc kcome
Suppose i delete the record where ID=2..still the sequence should be auto adjusted..ie.the record of ID=3 should become ID=2 automatically..there shouldn't be any gaps.

In a cursor, I declare a table variable like so:
DECLARE @TempTable TABLE(RowID INT IDENTITY, valueID int)
I then insert into that table from another table. The purpose is to get a list that looks like this after the insert:
RowID valueID1 348972 345223 94822
etc....
However, the next time through my loop (cursor) I want to restart my RowID identity property, because the next batch of valueID's should then again have a RowID starting from 1.
I tried
delete from @TempTable DBCC CHECKIDENT(@TempTable , RESEED, 0)
but I get 'Must declare the variable @TempTable table' error.
Is there a way to destroy and recreate that @TempTable variable?

Because of testing and deletion, my table of user groups starts at 15 or so. Now I want to insert a group for administrators but I would like to have the groupID be 1. I tried to turn off the identity seed property and insert it manually but that didn't work.
Is there any way to do this?
Thanks, Dave

Hi,
I have a table which has a field called x which is set to identity with seed 1 and incerement 1.
Currently the table has 100 records so the last value of x is 100.
I would like to adavnce the seed number to be 1000, so that the next insert into the table will be 1001...
This is possible to do through the Enterprise manager, but I would like a script to do it.
Does anyone know where such a script exists?
What I actually need is a script that creates a CREATE TABLE Statement for the table (including all info - columns,indexes etc...).
thanks

Hi ..
I have an issue here. I create a DB and some tables through a script in SQL Server. I have lot of tables in DB and quite a lot have identity columns with seed set to 1 and increment set to 1. The scripts executed fine and all the tables created. Now when I do the first insert records into the tables the identity column associated starts with 0 even though the seed is set at 1. Its the case with all the tables where the identity column are set. The first records into all these tables starts with 0 for all the identity columns.
I could'nt figure out what is causing this issue ..
Any fix for the issue ..
thanx in advance

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

My client has a need for the auto identity field to be 6 digits in length starting with the number 001000. They want the leading 0's preserved since this will be a casenumber. Even if I set the identity seed to 001000 it gets rid of the leading 0's. How can I get it to keep those?

I have a table with the following specifications:
[FutureArticleId] [bigint] IDENTITY(1,1) NOT NULL,
[cFutureArticleTitle] [nvarchar](50) COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[cDescription] [ntext] COLLATE SQL_Latin1_General_CP1_CI_AS NOT NULL,
[gCategoryId] [bigint] NOT NULL,
[cKeyword] [ntext] COLLATE SQL_Latin1_General_CP1_CI_AS NULL,
[bIsDeleted] [bit] NOT NULL CONSTRAINT [DF_tbl_FutureArticle_bIsDeleted] DEFAULT ((0)),
[tOnCreated] [datetime] NOT NULL,
[tOnUpdated] [datetime] NULL,
[gCreatedBy] [bigint] NOT NULL,
[gUpdatedBy] [bigint] NULL,
After some insertions and deletion from the UI, obviously there are gaps in the FutureArticleId column which is an identity column.
However, sometimes while inserting the records the records are being inserted into the gap and not in the next available Identity value.
Is there any table setting which I need to do, to stop this.
Please let me know
Thanks

I'm trying to have an identity column seed value specified with a local variable value as follows, however it
doesn't allow me to do it (Says cannot use a variable name for a seed value).
Any ideas or suggestions?
DECLARE @idvalue int
SELECT @idvalue = max(accountid) + 1
FROM account
CREATE TABLE accounttemp
(Accountid int IDENTITY(@idvalue,1),
name char(10),
address char(10))

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!

Sever: sql 2000
Replication: Merge
Issue:
I am having an issue with my audit table, This table is filled by Triggers on various tables through the database. All triggers are defied with "not for replication"
I have allocated 500k ranges, with 80% threshold to the publisher and subscriber databases for this table. The table only holds 225,000 records.
From time to time I get the following error "The identity range managed by replication is full and must be updated by a replication agent. The INSERT conflict occurred in database 'PublicationName', table 'AuditHistory', column 'AuditID'. Sp_adjustpublisheridentityrange can be called to get a new identity range."
When I looked into the issue yesterday I noticed that the identity range being used by replication was 334300001 -> 334799999, however the maximum value in the table was 334300096, meaning that only 95 records were inserted, which means it is no where near the 80% threshold.
Somehow the identity seed on the AuditHistory table had been changed to 334800104, which is outside the allowable range.
My question is what could cause the identity seed to get set to such a high number??
any thoughts would be great!

I'm using a stored procedure to create a table in sql 2000. One of the columns is an identity column. I need to set the seed to a max(number) from a column in another table, this column is not an identity column and can't be changed into one. I've been trying to set the seed by passing a variable. I continue to get errors so either I've got the syntax wrong or it's not possible to set the seed via a variable. Any words of wisdom would be appreciated.

Hi,
I've just recently learned that being an identity seed-column doesn't guarantee that you will always get unique values. It can double up and cause a violation of PK. If so, is there a work around this that doesn't involve a REINDEX? Cause if im home and my client suddenly experiences this in the middle of a busy day, that would be a total disaster. Any ideas on how i can avoid this or a workaround maybe? Thanks!

I am attempting to import data from a Lotus Notes database using DTS. The SQL table I am importing to has an identifying auto-number. I can't insert directly into it because the SQL server should, however I get an error if I ignore it in the DTS package. Is there any way to get around this?

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!

Can a Primary Key column also be a Identity column? The reason I am asking this question is because I have created a table and each time I insert data into the Address Table I am also inserting the AddressID, how do I get the Primary Key (AddressID column) to self generate ID values.
