Syntax
FILE_ID ( file_name )
Arguments
- file_name
Is an expression of type sysname that represents the name of the file for which to return the file ID.
Return Types
smallint
Remarks
file_name corresponds to the logical file name displayed in the name column in the sys.master_files or sys.database_files catalog views.
In SQL Server 2005, the file identification number assigned to full-text catalogs is greater than 32767. Because the return type of the FILE_ID function is smallint, this function cannot be used for full-text files. Use FILE_IDEX instead.
Examples
The following example returns the file ID for the AdventureWorks_Data file.
USE AdventureWorks;
GO
SELECT FILE_ID('AdventureWorks_Data')AS 'File ID';
GO
Here is the result set.
