Go into design mode of that table and select that field. You will get the field properties below. Go to “Identity Specification” option, set (Is Identity) as yes, set Identity Increment as 1, set Identity seed as 1.

After this execute the below command.

DBCC CHECKIDENT(‘Your Table Name’, RESEED, 0)

Thanks,

BTW, thanks so much for this blog, it has saved me headaches time and time again.

This is a common problem if you are using an int as your identity column. A better approach would be to use GUID, this is a unique value that can be entered against each row. You can see what it looks like by writing ‘Select NewID()’ This will show you an example of a GUID. The data type is known as UniqueIdentifier in the SQL table.

Hope this helps.

set rowcount 100000
Delete from “table_name”
where CALL_START_UTC between ’2008-12-25 00:00:00′ AND ’2008-12-31 23:59:59′

SET ROWCOUNT 0

your solution didnt work, i edited to:

set rowcount 10000
Delete from SMC_LONGDISTANCE_CDRS
where CALL_START_UTC between 12/25/2008 AND 01/30/2009

while @@rowcount>0

and result was :

how can i bulk delete without sending records to transaction log? and doesnt wait so long.

is this script a right solution, because i dont want to lose the id key:

DELETE from “table_name”
(call_start between ’08/01/2010 12:00:00 AM’ AND ’09/30/2010 11:59:59 PM’)
DBCC CHECKIDENT(“table_name”, RESEED, 0)

I have an issue. I have hosted a web application with sql serve db in a central server in state capital and there are 10 other districts here. every client machine is accessing the apllication through the web. but if there is no connectivity they will enter the data into the local serve within the district and this data will be updated to the Central server whenever the connection establishes.

The problem is every table is having an identity auto increment column which is primary key and this key is referencing as foreign key in the transaction tables. so at the time of synchronisation the identity will get affected and the transaction data will get affected worse. How can I override this situation. Please help on this

I have a table which has an identity column in it. This table is added as an article to an existing Peer to peer replication. I tried reseeding the indentity column on this table to 10000 using the below command

DBCC CHECKIDENT ( ‘AutoProvision.ApprovalRequestInfo_New1′ , RESEED, 10000000)

No errors are reported when I run the above command , but if I go to verify the identity set in this table using the below command

DBCC CHECKIDENT ( ‘AutoProvision.ApprovalRequestInfo_New1′ )
go

I get the following output

Checking identity information: current identity value ‘NULL’, current column value ‘NULL’.
DBCC execution completed. If DBCC printed error messages, contact your system administrator.

I thought this was because the table was added as an article as part of the replication , so I added an additional new table in the DB, with no records ( virgin ) , and then tried to reseed the indentity column on this table to 1000,
I used the DBCC CHECKIDENT to check the indentity , but it still returned me

Checking identity information: current identity value ‘NULL’, current column value ‘NULL’.

Any idea , why the table is not being reseeded ?

Thanks

thanks for the feedback.

managed to find a built in function that assisted me:

Select Row_Number() Over(Partition By Customer_ID order by Customer_ID, Trans_ID) as Trans_Number

I suggest that you write a good T-SQL to analyse your data & do organise it the way you want it.

Try going through your data using a cursor or any optimised while loop logic and add the extra digit to the data you want.

Chris Musasizi

Customer_ID Trans_ID
1000 210
1001 212
1001 254
1001 300
1002 123
1003 155
1003 290
1004 230
1004 267
1004 281

I need to add in an extra column which counts each transaction instance for each Customer_ID. It should look like below:

Customer_ID Trans_ID Trans_number
1000 210 1
1001 212 1
1001 254 2
1001 300 3
1002 123 1
1003 155 1
1003 290 2
1004 230 1
1004 267 2
1004 281 3

thanks in advance.

good luck,

I actually dont knw about how to reset my identity value, i was facing this problem every time when I want to truncate a table which is referenced by another child tables.

It is very helpful to me.

And I want to Thank You on behalf of all my folks (people who work on database) for creating such a beautiful environment to share our knowledge and solve different kinds of problems encounterd.

If you have few rows like just a few thousand rows then your server needs a good performance drill down at database level, OS and Hardware levels.
You may find out that the problem lies elsewhere.

Try to maintain your database by checking the integrity of your table first, this might be good for a start.

Under normal circumstances, issuing a TRUNCATE TABLE runs faster than issuing a DELETE statement.

DBCC CHECKIDENT should run instantly.

Chris Musasizi

thanx…thanx very much…

Earlier it is : DBCC CHECKIDENT (schools.tblCaste,reseed,0)

Success: DBCC CHECKIDENT (‘schools.tblCaste’,reseed,0)

I use the statement
DBCC CHECKIDENT(mytable, RESEED, 350) in one of my stored procedures.

The table mytable needs to be truncated before I call the above statement, due to stored procedure logic requirements.

However, I see that the execution takes very long time. Sometimes. it takes around 20-30 seconds to complete the execution of this statement. Cant see any reasons.

There are no performance issues with any of the other database objects..in general.

If you can help me answer this problem, its highly appreciated. I follow your blog quite often and I appreciate you for all the work you do for the community.
