数据库脚本：

CREATE   TABLE   [ dbo ] . [ Pictures ]  (
     [ kFileName ]   [ bigint ]   IDENTITY  ( 1 ,  1 )  NOT   NULL  ,
     [ Picture ]   [ image ]   NULL  ,
     [ FileName ]   [ varchar ]  ( 250 ) COLLATE SQL_Latin1_General_CP1_CI_AS  NULL  
)  ON   [ PRIMARY ]  TEXTIMAGE_ON  [ PRIMARY ]
GO

CREATE   PROCEDURE   [ dbo ] . [ UploadFile ]
(
     @Picture   image ,
     @FileName   varchar ( 250 ),
     @kFileName   bigint  output
)
AS
insert   into  Pictures(Picture, FileName)  values  ( @Picture , @FileName )
set   @kFileName   =   @@IDENTITY
GO
