Linking control levels in DataLinks

You can create a DataLink column with different link controls.

NO LINK CONTROL
If a DataLink column is created with NO LINK CONTROL, no linking takes place when rows are added to the SQL table.
FILE LINK CONTROL with FS permissions
If a DataLink column is created with FILE LINK CONTROL with file system (FS) permissions, the system verifies that each DataLink value is a valid URL, with a valid server name and file name.
FILE LINK CONTROL with DB permissions
If a DataLink column is created with FILE LINK CONTROL with database (DB) permissions, the URL is verified, and all existing permissions to the object are removed.
