JSP调用SQL Server存储过程的实例
创建表
CREATE TABLE [BookUser] ( [UserID] [int] IDENTITY ( ) NOT NULL [UserName] [varchar] ( ) COLLATE Chinese_PRC_CI_AS NOT NULL [Title] [nvarchar] ( ) 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] ( ) 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( ) @Title varchar( ) @Guid uniqueidentifier @BirthDate DateTime @Description ntext @Photo image @Other nvarchar( ) @UserID int output As
Set NOCOUNT ON If Exists (select UserID from BookUser Where UserName = @UserName) RETURN ELSE Begin INSERT INTO BookUser (UserName Title Guid BirthDate Description Photo Other) VALUES(@UserName @Title @Guid @BirthDate @Description @Photo @Other) SET @UserID = @@IDENTITY RETURN End GO
