	,@ContentType VARCHAR(50)
	,@Data VARBINARY(MAX)
AS
BEGIN
	SET NOCOUNT ON;
	BEGIN TRY
		IF NOT EXISTS(SELECT Name FROM tblFiles WHERE id = @id)
		BEGIN
			INSERT INTO tblFiles(Name, ContentType, Data) 
            VALUES (@Name, @ContentType, @Data)
		END
		ELSE
		BEGIN
			UPDATE tblFiles
			SET Name = @Name
			,ContentType=@ContentType
			,Data = @Data
			WHERE id = @id
		END
	END TRY
	BEGIN CATCH
