Has anybody ever tried to do this. I can't figure it out. All I want to do is take an existing table that already has values in the column that I want to change and add the identity property to yes and set the identity seed and increment to a specific number. I know you can do it in the CREATE TABLE statement but is there a way to use the ALTER TABLE command?

Can any body tell me that how we can attach IDENTITY property to an existing int column
How do i drop/remove the identity property for an existing column in all Tables where the Identity column is a primary key.
The Script below was used to find all the tables that have an Identity Column as a primary key in a database. Now i want to remove the identity property from the Identity Columns that have a primary key in the database.
select pk.table_name, c.column_name,
from information_schema.table_constraints pk
INNER JOIN information_schema.key_column_usage c ON c.TABLE_NAME = pk.TABLE_NAME
and c.constraint_name = pk.constraint_name
where constraint_type = 'PRIMARY KEY'
and COLUMNPROPERTY(object_id(pk.table_name), column_name, 'IsIdentity') = 1
ORDER BY pk.table_name, c.column_name
Is there any way to remove IDENTITY property on particular table? I tried removing IDENTITY property using Manangement studio, but this operation behind the scene use migration concept that is by creating tmp table and then populating with data; droping the orginal and renaming the tmp back to original.
Second, i want some kind of generic solution using certain system table like aya.sysobjects, sys.identitycolumn etc such a way that i should be able to remove the idenity property from all of the table accross a database.

I have created a table as below mentioned. Then I want to alter the ID column as identity(1,1) without dropping the table as well as losing the data.
create table dbo.IdentityTest
(
id int not null,
descript varchar(255) null,
T_date datetime not null
)
Hi Friends,
I have a existing table named as activity, and have the column like ID,Description. I want to add the Identity for the ID column using script only.. Have any ideas how to do in sql query analyser?
Thanks in Advance
Hi, I have the lovely task of overhauling some of our SQL-based systems. I've found many tables that don't have unique identifying numbers that really should have them. I've searched around and people keep mentioning the Identity field as being similar to Autonumber in Access. The only examples I could find involved setting up a new table... but I need to add (and populate) an identity column to an existing database table. Does anyone know the command for this?
Example... my table is called PACountyTown. It currently has 3 columns: County, Town, and Area. I wish to call the identity-ish field RecordID.
Thanks in advance!
I removed all constraints in order to load a bunch of data into a table, now I'm wondering if I can add an identity column to this table which does contain data or if I have to create a new table with the identity column and insert the data into that.
thx

I am working with a table in SQL server. I have a column that I want to designateas an identity column. I am not able to do this, because the field for "Identity Specification" is not editiable.
What I did was I went to sql server, right clicked and selected "Modify".The column properties dialog box/edit grid is then displayed with attributesthat I can modify.
There are two major nodes in this dialog box. One is named "General" and the otheris named "Table Designer". I expand the "Table Designer" node and then go to the node labeled "Identity Specification" It is here where I would like to edit thevalues.
The values that are listed for edit are listed below. BUT, the problem is thatI can place my cursor in those fields, but I am not able to change/edit them.Can anyone tell me what the problem is here? and how I can fix it?
+Identity Specification (Is Identity) Identity Increment Identity Seed
We want to add a new int identity column as a primary key to an already existing table that has a primary key on Guid. Here is the DDL:
CREATE TABLE [dbo].[VRes](
[VResID] [uniqueidentifier] NOT NULL,
[Mes] [varchar](max) NOT NULL,
[PID] [uniqueidentifier] NOT NULL,
[Segt] [int] NOT NULL,
[code]....
Also we currently have 3 million rows on this table. Is having an integer column as identity column and primary key better or shd I consider using BigInt?

Hi,
I have a VB script that I am using to run various DTS procedures. One of these involves using DataPumpTransformCopy to copy data from one table to another. The destination table has an Identity field that I would like to disable for the duration of the Transform.
I have tried opening a Command Object and running the "SET IDENTITY_INSERT" function beofre and after the Transform but although it doesn't produce any errors it doesn't seem to actually do anything...
I figure I need to try using the ALTER TABLE to disable the IDENTITY but I can't find an example of how to do this anywhere.. can anyone help me out here?
Many Thanks,
Seoras
How can i remove identity property of a particular table with sql command.
Thanks.
I assume that the identity property is stored within a given database, so there should be no need to run dbcc checkident after restoring from a backup. Is this a correct assumption?

Hi,
Please let me know if it is possible to replicate a table with identity property defined in it. Both the publisher and subscriber tables have identity property defined. Which option should be used while setting up transactional replication to allow the identity values at the publisher pushed to the subscriber, which also has identity property defined? Not for replication option with the identity property also fails. Whichever option I choose I get the error, 'An explicit value for the identity column in table 'jobs_id_nfr' can only be specified when a column list is used and IDENTITY_INSERT is ON.' This works only if the identity property is not defined at the subscriber. But, I need to have the identity property defined at the subscriber also because the subscriber should be an exact copy of production.
Thanks in advance,

Hi all,
Have anyone faced the timeout issue when setting a IDENTITY property of a column to NO.
Is there any way to resolve it ?
Note : The table on which I'm doing the operation is having approx 50 million records.
Thanks,
Hariarul.
I get the below error :
'TrnBillDetail' table
- Unable to modify table.
Timeout expired. The timeout period elapsed prior to completion of the operation or the server is not responding.

I have met the interview question, I provide answer like the following from my experience. I don't know it is correct or need to supplement. Thank you for help.
Question: How to identity existing data for updating in SSIS?
Answer:
If you have the same key columns such as primary key or business key, you just use them to identify existing records from data source to destination.
If you use different key columns between data source and destination, you can create permanent link table which will store business key for data source and destination, and you can compare records from linking table when you update data.
I re-created a publication that was having problems and it gives this error when I start the snapshot agent from SQL Server Management Studio: I am stuck on how to resolve - any ideas?
"The publisher's identity range allocation entry could not be found in MSmerge_identity_range table. Transaction count after EXECUTE indicates that a commit or ROLLBACK TRANSACTION statement is missing. Previous Count = 1, current count = 2."
select * from MSmerge_identity_range returns 19 entries but I don't know how to fix.
I have tried deleting and re-creating but always get this error.
My other publications and subscriptions are working fine and I was able to create a new test publication that worked but can not get this one to work that worked fine up until today.
Any ideas?
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?
Hi,
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 am having problems exporting data into a flat file using specific code page. My application has a variable "User::CodePage" that stores code page value (936, 950, 1252, etc) based on the data source. This variable is assigned to the CodePage property of desitnation file connection using Property expression.
But, when I execute the package, the CodePage property of the Destination file connection defaults to the initial value that was set for "User:CodePage" variable in design mode. I checked the value within the variable during runtime and it changes correctly for each data source. But, the property of the destinatin file connection doesn't change and results in an error.
[Flat File Destination [473]] Error: Data conversion failed. The data conversion for column "Column01" returned status value 4 and status text "Text was truncated or one or more characters had no match in the target code page.".
[DTS.Pipeline] Error: The ProcessInput method on component "Flat File Destination" (473) failed with error code 0xC02020A0. The identified component returned an error from the ProcessInput method. The error is specific to the component, but the error is fatal and will cause the Data Flow task to stop running.
If I manually update the variable with correct code page and re-run the ETL, everything works fine. Just that it doesn't work during run-time mode.
Can someone please help me resolve this.
Thanks much.
Hi,
I developed a simple custom control flow component which has several read/write properties and one readonly property (lets call it ROP) whichs Get method simple returns the value of a private variable (VAR as string). In the Execute method the VAR has a value assigened. When I put the value of ROP or VAR into MsgBox I can see the correct value. However when I execute the component I can not see the value of the ROP in the property window. I see the property but its value is empty string. For example when I put a breakpoint to postexecute or check the property before click OK in a MsgBox I would expect that the property value would be updated in SSIS as well. Is there a way how to display correct values of custom tasks properties in property window?
Thanks for any hints.
