JSP调用SQL Server存储过程的实例:


创建表:


CREATE TABLE [BookUser] (
    [UserID] [int] IDENTITY (1, 1) NOT NULL ,
    [UserName] [varchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL ,
    [Title] [nvarchar] (50) COLLATE Chinese_PRC_CI_AS NOT NULL ,
    [Guid] [uniqueidentifier] NOT NULL CONSTRAINT [DF_BookUser_Guid] DEFAULT (newid()),
    [BirthDate] [datetime] NOT NULL ,
    [Description] [ntext] COLLATE Chinese_PRC_CI_AS NOT NULL ,
    [Photo] [image] NULL ,
    [Other] [varchar] (50) COLLATE Chinese_PRC_CI_AS NULL
CONSTRAINT [DF_BookUser_Other] DEFAULT ('默认值'),
    CONSTRAINT [PK_BookUser] PRIMARY KEY  CLUSTERED
    (
        [UserID]
    )  ON [PRIMARY]
) ON [PRIMARY] TEXTIMAGE_ON [PRIMARY]
GO

 

 

 

创建存储过程:


CREATE PROCEDURE InsertUser
@UserName varchar(50),
@Title varchar(255),
@Guid  uniqueidentifier,
@BirthDate DateTime,
@Description ntext,
@Photo image,
@Other nvarchar(50),
@UserID int output
As

Set NOCOUNT ON
If Exists (select UserID from BookUser Where UserName = @UserName)
RETURN 0
ELSE
Begin
INSERT INTO BookUser (UserName,Title,Guid,BirthDate,Description,Photo,Other)
VALUES(@UserName,@Title,@Guid,@BirthDate,@Description,@Photo,@Other)
SET @UserID = @@IDENTITY
RETURN 1
End
GO
