SQL Error 3452: Inconsistency Among Database Metadata

SQL server error 3452 occurs while upgrading the database to any of the latest release of the SQL server. When the upgrade process gets completed, the advanced version sometimes works inappropriately and this confirms that the above said error has taken place.

In SQL database, while recovering identity values, if the specified process shows inconsistency among metadata components, it affirms the existence of SQL error 3452. It implies that the existing identity value does not match with the maximum value assigned in the table.

Recovery of database '%.*ls' (%d) detected possible identity value inconsistency in table ID %d. Run DBCC CHECKIDENT ('%.*ls').

Rectify SQL Error Code 3452 Through DBCC

Executing Database Console Commands with appropriate syntax might help in removing the error message. These commands are highly preferred as they help analyzing the logical and physical inconsistencies among integrated data components.

The DBCC CHECKIDENT is used for checking the identity values in the specified database tables. Running the above stated command with appropriate arguments; helps modifying or changing the identity values of the table, if it is required to do so.

Required Permissions and Authorities

There are several permissions that must be acquired before starting the task:

The user must be the authorized member of:

  • "sysadmin" fixed server role.
  • "db_ddladmin" fixed database role.
  • "db_owner" fixed database role.

Related DBCC Arguments & Syntax


Executing DBCC CHECKIDENT along with RESEED argument will help resetting the existing identity value.

When the issues with the identity values are resolved, the SQL error 3452 automatically gets eliminated and the server application will perform appropriately.

"DBCC CHECKIDENT (table_name, RESEED, new_reseed_value)"

Using this syntax, the new value can be assigned to the identity column. There are some rules associated with this operation. The "new_reseed_value" will be allotted to the existing tables:

  • If the table contains no rows and is empty since its creation.
  • If the existing rows have been deleted by using TRUNCATE TABLE.

Note: The existing identity value and the maximum value assigned to the identity columns of the table must be same. In case of any sort of inconsistencies, reset the values for avoiding further errors as well as disruptions in the smooth sequence of the values.

Relevant Information

To understand the DBCC CHECKIDENT in detail; it is important to understand the associated terms:

What is Seed? In SQL Server, 'Seed' implies to internal value that is used for generating the next value or subsequent value in the existing sequence.

What is Reseed? The process of changing or editing the seed value assigned to the column is termed as 'Reseed'. This can be done after deleting the existing records or archiving data.

Seeding operation can be performed on the identity columns at any time as it is entirely safe procedure and does not involve any major risk. However, to initiate the Reseeding operation; appropriate checks are required to be performed on the identity columns integrated within tables.

An Alternate Solution: However, during the process of assigning new data to the identity tables; if any of the components gets accidently deleted; SQL database recovery tool can be used to recover the erased data. The tool also helps in the recovery of data from corrupted MDF as well as NDF files.
