Resetting/Changing the identity[auto-increment number] column value of a table

Dushyanth Jyothi — Wed, 15 Jul 2009 13:27:04 +0000

Resetting/Changing the identity[auto-increment number] column value of a table

DBCC CHECKIDENT checks the current identity value for the specified table and, if it is needed, changes the identity value. You can also use DBCC CHECKIDENT to manually set a new current identity value for the identity column

Tested only on MS SERVER 2008

Table to alter:

CREATE TABLE Admin.DocumentType_List
(
	DocumentType_ID INT IDENTITY(0,1) NOT NULL,
	DocumentType NVARCHAR(250) NOT NULL,
	Description_ NVARCHAR(250) NOT NULL
CONSTRAINT PK_DocumentType PRIMARY KEY (DocumentType_ID)
)

In the above code ‘DocumentType_ID’ column has declared as Identity, having auto increment value by 1 starting with 0. This means the first row inserted will have ‘DocumentType_ID’ value of 1. then 2,3,so on..

In future if we want to reset this value, for what so ever reason, we can use T-SQL:

DBCC CHECKIDENT('Admin.DocumentType_List', RESEED, 0)

This code will reset table Identity back to 0.

Information schema is part of the SQL-92 standard, holds the structure if your database.

Applies to MS SQL SERVER 2008

T-SQL CODE to see the metada:

SELECT * FROM INFORMATION_SCHEMA.TABLES

SELECT 
TABLE_CATALOG,/*'TABLE_CATALOG' IS SQL-92 STANDARD NAME FOR 'DATABASE'*/
TABLE_SCHEMA,/*'TABLE_SCHEMA' IS SQL-92 STANDARD NAME FOR 'OWNER'*/
TABLE_NAME,
TABLE_TYPE

An error occurred when attaching the database

Dushyanth Jyothi — Tue, 14 Jul 2009 21:56:01 +0000

An error occurred when attaching the database – AdvenureWorks database

The below steps applies to MS SQL Server 2008

A. Make sure you enabled database instance to use FILESTREAM as instructed here:
http://msdn.microsoft.com/en-us/library/cc645923.aspx

B. If you downloaded Adventureworks from codeplex, make sure you have set the right user permissions to these files

C. Copy AdventureWorks2008_Data.mdf and AdventureWorks2008_Log.ldf to
‘C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\’
If you see a folder called ‘Documents’ in the downloaded files set, then copy this folder also to ‘C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\’

D. In the managment studio, open new query window and execute the below code: [Change the files path accordingly]

USE [master]
GO
CREATE DATABASE [Adventureworks] ON
( FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\AdventureWorks2008_Data.mdf' ),
( FILENAME = N'C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\AdventureWorks2008_Log.ldf' )
FOR ATTACH
GO
if not exists (select name from master.sys.databases sd where name = N'Adventureworks' and SUSER_SNAME(sd.owner_sid) = SUSER_SNAME() ) EXEC [Adventureworks].dbo.sp_changedbowner @loginame=N'sa', @map=false
GO

OR you can attach a databse either using MS:
1. In SQL Server Management Studio Object Explorer, connect to an instance of the Microsoft SQL Server Database Engine, and then expand that instance.
2. Right click Databases, then Tasks, and then click Attach.
3. In the Attach Databases dialog box, to specify the database to be attached, click Add; and in the Locate Database Files dialog box, select the disk drive where the database resides and expand the directory tree to find and select the .mdf file of the database; for example: C:\Program Files\Microsoft SQL Server\MSSQL10.MSSQLSERVER\MSSQL\DATA\AdventureWorks2008_Data.mdf

Optionall : Specify a different name, Change the ownership
4. When you are ready to attach the database, click OK.
