Dropping Or Removing The Identity Property From An Existing Column
Mar 7, 2008
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
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?
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?
I am trying to drop the "allow nulls" characteristics on an existing table column. I know that there are not Nulls currently in this column, nor will there ever be. How do I get rid of that "allow nulls" checkmark on an existing table structure? Thanks, Craig.
I'm creating a VB program that does some DB manipulations.
I need a programmatic to drop the Identity property (not the column data) so that the field will be just an Integer with the old data...
It seems like the only way is the EM way (creating a temp table with no identity on the column, copying the data into it, deleting the old table, and re-naming the temp...) I'm looking for a more inovative way, or possibly a way to automate the process (so I'll be able to do this for all tables in a database in a modular way).
We can easily remove identity columnn through enterprise manager but how can it be done through transact sql?
The only way i found is to create a new column and pass values if identity column in it and then remove this identity column is there any better method of doing it?
hi i export tables from Local to Online Server But some tables have a column with Identity=True But after export tables that Property is not True How I can change it True With Query Analyzer????????/
Is there a way to remove the Identity property of a column in SQL Server 2000? The statement: <code> ALTER TABLE <table name> ALTER COLUMN <column name> DROP IDENTITY </code> returns a syntax error. Thank you, Jeff
i need to alter all foreign keys in my database and uncheck the"Enforce relationship for replication" check box. Using the EM, Iextracted the code snippet below. unfortunately, when i run this testfrom query analyzer, then go back into the EM, the box is stillchecked.can anyone tell me what i am missing? any advice on unsetting thisattribute globally would be appreciated!BEGIN TRANSACTIONSET QUOTED_IDENTIFIER ONSET TRANSACTION ISOLATION LEVEL SERIALIZABLESET ARITHABORT ONSET NUMERIC_ROUNDABORT OFFSET CONCAT_NULL_YIELDS_NULL ONSET ANSI_NULLS ONSET ANSI_PADDING ONSET ANSI_WARNINGS ONCOMMITBEGIN TRANSACTIONALTER TABLE dbo.CustomerCustomerDemoDROP CONSTRAINT FK_CustomerCustomerDemo_CustomersGOCOMMITBEGIN TRANSACTIONALTER TABLE dbo.CustomerCustomerDemo WITH NOCHECK ADD CONSTRAINTFK_CustomerCustomerDemo_Customers FOREIGN KEY(CustomerID) REFERENCES dbo.Customers(CustomerID) NOT FOR REPLICATIONGOCOMMITthanks!!
Hi(SQL Server 2000)I have an existing table (t) with a column that is NOT an identity column(t.ID), but it has manually inserted "row numbers". I want to make thiscolumn become an identity column. This column is a key field to othertables, so I want to keep the row numbers that are allready inserted.From the Query Analyzer, how do I do this?Thanks in advance!Regards,Gunnar VøyenliEDB-konsulent asNORWAY
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 .
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.
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?
I need to add syntax to a stored procedure to check for the existence of a specific indexes on a table before dropping it. If they do not exist I need it to NOT through an error message. Performing this on a table is relatively simple: if exists (select * from sysobjects where id = object_id(N'[dbo].[TABLENAME]') and OBJECTPROPERTY(id, N'IsUserTable') = 1) drop table [dbo].[TABLENAME]
Since indexes are not represented in sysobjects how can I do this?
Is there a way to drop a column identity using TSQL?
Also, does this code look correct?
declare @max1 int declare @max2 int select @max1 = max(acid) from cms_2a alter table cms_3a add cwid int identity(@max1, 1) <------ Error select @max2 = max(cwid) from cms_3a alter table cms_4a add cwtid int identity(@max2, 1) <------ Error
I do not have identities on tables cms_3a and cms_4a, but I do have an identity on cms_2a.
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. thanks. varun
I have a table with several columns of information that I wish to set up some form of schedule to go through this data and remove any special characters that may interfere with other code processes.
Mainly the coma's and the apostrophes. It really messes with my asp pages and scripts when retrieving this information and trying to do other things with it, so I need to figure out how to remove these from the tables so it does not cause these issues.
Knowing this, I cannot figure out how to keep the data in the row/column and just extract the special characters from that data. The other problem is, everything I try requires me to insert either a coma or apostrophe as part of the code string which in lies my issue.
How can I parse through my data, leave the data as-is, but just get rid of coma's, apostrophes, and double quotes?
Does anyone have a basic example that I can use to expand on?
Hello friends, I am using sql server 2005. In some tables to create the column Autoincrement I had set the 'Idetity Specification' property to 'Yes'. I want to know that how can we do it through sql scripts i.e. by writing query. Please let me know Thanks & RegardsGirish Nehte
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.
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.
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.
Hi All!We are doing new development for SQL Server 2000 and also moving fromSQL 7.0 to SQL Server 2000.What are cons and pros for using IDENTITY property as PK in SQL SERVER2000?Please, share your experience in using IDENTITY as PK .Does SCOPE_IDENTITY makes life easier in SQL 2000?Is there issues with DENTITY property when moving DB from one serverto another? (the same version of SQL Server)Thank you in advance,Andy
