IDENT_SEED (Transact-SQL)

Applies to: SQL Server Azure SQL Database Azure SQL Managed Instance SQL database in Microsoft Fabric

The IDENT_SEED system function returns the original seed value specified when creating an identity column in a table or a view. Changing the current value of an identity column by using DBCC CHECKIDENT doesn't change the value returned by this function.

Transact-SQL syntax conventions

Syntax

IDENT_SEED ( 'table_or_view' )

Arguments

table_or_view

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.

Return types

numeric(@@MAXPRECISION,0))

Exceptions

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 might return NULL if the user doesn't have any permission on the object. For more information, see Metadata Visibility Configuration.

Remarks

The IDENT_SEED function is not available for identity columns in Fabric Data Warehouse.

Examples

A. Return the seed value from a specified table

The following example returns the seed value for the Person.Address table in the AdventureWorks2025 database.

Note

In Azure SQL Database and SQL database in Microsoft Fabric, the USE statement isn't available. Instead, connect directly to intended database and run the rest of the code sample.

USE AdventureWorks2022;  
GO  
SELECT IDENT_SEED('Person.Address') AS Identity_Seed;  
GO

B. Return the seed value from multiple tables

The following example returns the tables in the AdventureWorks2025 database with an identity column with a seed value.

USE AdventureWorks2022;  
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

Here is a partial result set.

TABLE_SCHEMA       TABLE_NAME                   IDENT_SEED  
------------       ---------------------------  -----------  
Person             Address                                1
