sql server programming : Removing IDENTITY from a tabe column
I have created a table containg a column with IDENTITY keyword. I have data in the table. Now i need to alter this table without IDENTITY for that column. Please help me get a sql script to do this one. The creation scirpt for the table is : if exists (select * from dbo.sysobjects where id = object_id(N'[dbo].[EventLog]') and OBJECTPROPERTY(id, N'IsUserTable') = 1) drop table [dbo].[EventLog]; CREATE TABLE [dbo].[EventLog] ( [RecordId] [int] IDENTITY (1, 1) NOT NULL , [eventId] [int] NOT NULL , [eventType] [int] NOT NULL , [eventDateTime] [datetime] NULL , [AimNumber] [int] NULL , [eventMsg] [nvarchar] (64) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [opId] [nvarchar] (50) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [comments] [nvarchar] (64) COLLATE SQL_Latin1_General_CP1_CI_AS NULL , [eventProperties] [nvarchar] (1024) COLLATE SQL_Latin1_General_CP1_CI_AS NULL ) ON [PRIMARY]; ALTER TABLE [dbo].[EventLog] WITH NOCHECK ADD CONSTRAINT [PK_EventLog] PRIMARY KEY CLUSTERED ( [RecordId] ) ON [PRIMARY] ; Now i need script for altering the just identity column.?????

Hi,
You can not remove the IDENTITY property using Alter table command. Only way is export data into a new table using 1. SELECT * INTO newtable from existing table 2. create new table with out identity 3. insert the data from new table 4. drop the existing table and rename the new table using sp_rename Enterprise manager internally almost does the above steps to remove identity property.
