Transact-SQL syntax conventions
IDENT_SEED ( 'table_or_view' )
' table_or_view '
Is an expression that specifies the table or view to check for an identity seed value. table_or_view can be a character string constant enclosed in quotation marks, a variable, a function, or a column name. table_or_view is char, nchar, varchar, or nvarchar.
numeric(@@MAXPRECISION,0))
Returns NULL on error or if a caller doesn't have permission to view the object.
In SQL Server, a user can only view the metadata of securables that the user either owns or is granted permission on. This security means that metadata-emitting, built-in functions such as IDENT_SEED may return NULL if the user doesn't have any permission on the object. For more information, see Metadata Visibility Configuration.
The following example returns the seed value for the Person.Address
table in the AdventureWorks2022 database.
USE AdventureWorks2022;
GO
SELECT IDENT_SEED('Person.Address') AS Identity_Seed;
GO

FROM INFORMATION_SCHEMA.TABLES
WHERE IDENT_SEED(TABLE_SCHEMA + '.' + TABLE_NAME) IS NOT NULL;
GO
