The Art of SQL Server FILESTREAM - Red Gate Software

Chapter 2: Getting Started with FILESTREAMFirst, you have to drop the FILESTREAM column from the table (Listing 2-29).-- Drop the FILESTREAM columnALTER TABLE Items DROP COLUMN ItemImageListing 2-29:Dropping the FILESTREAM column from the Items table.Note that the association between the FILESTREAM filegroup and the table remains, evenafter dropping the FILESTREAM column; SQL Server still thinks that the FILESTREAMfilegroup is not empty. The table is still linked to its FILESTREAM filegroup even thoughthere are no FILESTREAM columns in the table.Next, you must disassociate the table from its FILESTREAM filegroup by setting theFILESTREAM_ON attribute to NULL. Listing 2-30 shows how to do this.-- Disassociate table "items" from its FILESTREAM filegroupALTER TABLE Items SET (FILESTREAM_ON = "NULL")Listing 2-30:Disassociating a table from its FILESTREAM filegroup.Now you can remove the FILESTREAM file and filegroup using ALTER DATABASE. Listing2-31 shows how to remove the FILESTREAM capabilities from the example database.-- Remove the FileALTER DATABASE NorthPole REMOVE FILE NorthPoleFS ;-- Remove the FilegroupALTER DATABASE NorthPole REMOVE FILEGROUP NorthPoleFS ;Listing 2-31:Removing FILESTREAM features from a database.87
