Hi Dave,
It’s worth notting that DBCC commands should only be used on a local server.
If you tried a command like this: DBCC CHECKIDENT (‘LINKD_SERVER.DB.SCHEMA.TABLE’, NORESEED); then you will get the following error from SQL server:

Server: Msg 2501, Level 16, State 2, Line 1
Could not find a table or object named ‘LINKD_SERVER.DB.SCHEMA.TABLE’. Check sysobjects.

I recommend you to run DNCC CHECKINDENT on the table by connecting directly to the SQL instance that manages the database where your table is.

It is however possible to run DBCC commands outside a database but on the same instance as follows:
DBCC CHECKIDENT (‘DB.SCHEMA.TABLE’, NORESEED);
I hope this answers your query.

God bless,
Chris Musasizi

How can we reseed or use the DBCC CheckIdent on a table with the prefix of a link server name. I get a syntax error when prefixing the table location with a link server name, e.g. DBCC CHECKIDENT ([LinkServerName].DBName.dbo.[tableName], RESEED, 0)

Charl,
Please delete content of a table by issuing any of the following SQL statement:

DELETE FROM Table_Name;
TRUNCATE TABLE Table_Name;

Replace Table_Name with the actual table whose content you want to delete.

Deleting a whole database means that you will need some privileges, that is database admin privileges or database owner privileges.

To delete a database, issue the following SQL statement:
DROP DATABASE Database_Name;

Regards,
Chris Musasizi

I was dropping and recreating tables for my unit (integration) tests and came across this reseed problem for virgin tables. My (ugly) fix was to 1) insert row into the table 2) delete all rows 3) reseed 4) insert (again) into the table. This way I could know for sure what id the inserted row got.

Vladimir

if ur table it’s new u must use:

DBCC CHECKIDENT (yourtable, reseed, seed_value)

but if u just delete that table u can use:

DBCC CHECKIDENT (yourtable, reseed, 0)

I have a table designed by a FORMER employee. There was no primary key created. In the table there are 7500 some records. The values started @ 1 through 2145, then 1600 columns are null. Then the index begins @ some random number and continues ASC. Is there a way for me to just reset the FamilyFriendSurveyID column in the entire table?, I need to now make this column be a primary key for the table, can this be done to auto increment starting @ 1? Thank you in advance for your help!!!

Thanks to Dave for the OP and to Ron Moses for the virgin table observation. I had been troubleshooting this for some time. Glad to have found this post.

Thanks again,

We experience a strange problem. Identity field of a table is set to [1,1] by generating script. Every time, when we drop the whole database, and then re-create it by running script in SQL Server 2008 Management Studio, and then insert a record into that table programmatically (C# code), SQL Server set identity field record of that first record to 0 instead of 1!
Then we also programmatically delete all records from that table and then execute
DBCC CHECKIDENT(‘” + targetTableName + “‘, RESEED, 0)

Next time, the same C# function inserts records correctly, with identity field starting from 1 as expected.

So, again, identity field does not want to behave correctly if database was just created by script. After inserting a record and deleting it, everything works fine.

Is it SQL Server 2008 bug? Any idea on possible workaround?

Hi mithilesh kumar,
Identity columns does not stand for uniqueness,
Unless you don’t define identity column as part of Primary Key.

Does DBCC RESEED works with replicated databases? Can I change the identity value on a subscription database?
