IDENT_SEED Function ~ Beginner School

IDENT_SEED

This function 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.

Syntax

IDENT_SEED ( 'table_or_view' )

Arguments

' table_or_view '

Is an expression that specifies the table or view to check for a 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

Exceptions

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.
