Returns the original seed value (returned as numeric(@@MAXPRECISION,0)) that was specified when an identity column in a table or a view was created. Changing the current value of an identity column by using DBCC CHECKIDENT does not change the value returned by this function.
Returns NULL on error or if a caller does not have permission to view the object.
In SQL Server, a user can only view the metadata of securables that the user owns or on which the user has been granted permission. This means that metadata-emitting, built-in functions such as IDENT_SEED may return NULL if the user does not have any permission on the object. For more information, see Metadata Visibility Configuration.
A. Returning the seed value from a specified table
The following example returns the seed value for the Person.Address table in the AdventureWorks database.
B. Returning the seed value from multiple tables
The following example returns the tables in the AdventureWorks database that include an identity column with a seed value.
USE AdventureWorks2012; GO SELECT TABLE_SCHEMA, TABLE_NAME, IDENT_SEED(TABLE_SCHEMA + '.' + TABLE_NAME) AS IDENT_SEED FROM INFORMATION_SCHEMA.TABLES WHERE IDENT_SEED(TABLE_SCHEMA + '.' + TABLE_NAME) IS NOT NULL; GO
