How To Reset An Identity Column

Nov 27, 2007

Hi

I have a table with Identity column starting from value 1 and autoincrementing 1 for every new value. I inserted (5) rows and then deleted these rows. But, when i insert a new row, it was taking the last identity value(5)and inserting the rows with next identity value i.e., 6 for this column. I dont want that. Everytime, I delete and insert rows in to this table.I wanted the rows to start with 1 for this column.

Any help on this is highly appreciated.

Thanks!

Deletion And Identity Reset

Oct 13, 2005

Obviously to delete all records from DB table is simple, however, I would like to make my whole Live DB pretty much empty. I've copied all my data from my test DB over to my live DB (didn't mean to but I did). I would like to remove all the data and the identity values, resetting them back at their original values. Is there a simple way or do I have to do it the hard way. That being going in and removing Identity, saving and then placing identity back on the DB Table.

Reset IDENTITY After Table Data Import?

Jul 9, 2004

I have a remote DB I am wokring with at present. The DBA has provided me with a non owner LOGIN so I can't copy tables from the live to the staged DB as objects I can only copy tables and data.

The PKEY and IDENTITY COLUMNS get reset to just regular columns on each table. I can restore the PKEY constraint and have come across the DBCC CHECKIDENT to get the new ident value. I just can't figure out how to set a column to be an identity. The ALTER TABLE command isn't having any of it.

I am obviously missing the right bit on Books online

any suggestions?

many thanks

How To Use Identity On Non-identity Column (with Concurrence)

Aug 1, 2014

I'm working with a third-party database (SQL Server 2005) and the problem here is the following:

- There are a bunch of ETL processes that needs to insert rows on a table (let's call this table T) and at the same time, an ERP (owner of T) is up and running (reading, updating and inserting on T).

- The PK of T is an Integer.

Today all ETL processes uses (select max(ID) + 1 from T) to insert new rows, so just picture the scenario. It is a mess! Everyday they get duplicate key error when 2 or more concurrent processes are trying to insert a row (with the max) at the same time.

Considering that I can't change the PK, what is the best approach to solve this problem?

To sum up:

* I need to have processes in parallel inserting on T

* I can't change anything on T

* The PK is NOT an Identity

How To Refer A Column When The Referencing Column Is An Identity Column

Oct 16, 2006

Hi all,

The requirement is to have a table say 'child_table', with an Identity column to refer another column from a table say 'Parent_table'..

i cannot implement this constraint, it throws the error when i execute the below Alter query,

ALTER TABLE child_table ADD CONSTRAINT fk_1_ct FOREIGN KEY (child_id)
REFERENCES parent_table (parent_id) ON DELETE CASCADE

the error thrown is :
Failed to execute alter table query: 'ALTER TABLE child_table ADD CONSTRAINT
fk_1_ct FOREIGN KEY (child_id) REFERENCES parent_table (parent_id) ON DELETE
CASCADE '. Message: java.sql.SQLException: Cascading foreign key 'fk_1_ct' cannot be
created where the referencing column 'child_table.child_id' is an identity column.

any workarounds for this ?
