The Art of SQL Server FILESTREAM - Red Gate Software

Chapter 4: FILESTREAM with Entity Framework and LINQ to SQLCreate the stored procedure interfaceOur first step is to create a stored procedure for adding new items into the table (Listing4-3). This stored procedure will be invoked from the EF project.CREATE PROCEDURE [dbo].[SaveItem] (@ItemNumber VARCHAR(20),@ItemDescription VARCHAR(50),@ItemImage VARBINARY(MAX)) ASINSERT INTO dbo.Items(ItemGuid,ItemNumber,ItemDescription,ItemImage)SELECTNEWID(),@ItemNumber,@ItemDescription,@ItemImageRETURN SCOPE_IDENTITY()Listing 4-3:Creating a stored procedure to add items to the table.Note that this procedure accepts item information including the image, which will goto the FILESTREAM column of the table. Because we are using the T-SQL interface forwriting into the FILESTREAM column, a VARBINARY(MAX) variable is used. Rememberthat the FILESTREAM columns appear as VARBINARY(MAX) data type values whenaccessing them from T-SQL.135
