下面介绍一个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 AsSet NOCOUNT ONIf Exists (select UserID from BookUser Where UserName = @UserName)RETURN 0ELSEBeginINSERT INTO BookUser (UserName,Title,Guid,BirthDate,Description,Photo,Other) VALUES(@UserName,@Title,@Guid,@BirthDate,@Description,@Photo,@Other)SET @UserID = @@IDENTITYRETURN 1EndGO
JSP代码：
<%@ page language="java" contentType="text/html; charset=UTF-8" pageEncoding="UTF-8"%><%@ page import = "java.sql.*"%><!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd"><html xmlns="http://www.w3.org/1999/xhtml"><head></head><body><%//注意：下面的连接方法采用SQL Server的JDBC，先下载sqlserver驱动。Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");String url="jdbc:sqlserver://localhost:1433;databaseName=Book;user=sa;password="; String sql = "{? = call InsertUser(?,?,?,?,?,?,?,?)}"; Connection cn = null;CallableStatement cmd = null;try{ cn = DriverManager.getConnection(url); cmd = cn.divpareCall(sql); java.util.UUID Guid = java.util.UUID.randomUUID(); String FilePath = application.getRealPath("") + "/test/logo.gif"; java.io.FileInputStream f = new java.io.FileInputStream(FilePath); Date rightNow = Date.valueOf("2007-9-9"); cmd.setString("UserName","mengxianhui"); //注意修改这里，存储过程验证了UserName的唯一性。 cmd.setString("Title","孟宪会"); cmd.setString("Guid",Guid.toString()); cmd.setString("BirthDate","2007-9-9"); cmd.setDate("BirthDate",rightNow); cmd.setString("Description","【孟子E章】"); cmd.setBinaryStream("Photo",f,f.available()); cmd.setString("Other",null); cmd.registerOutParameter(1,java.sql.Types.INTEGER); cmd.registerOutParameter("UserID",java.sql.Types.INTEGER); cmd.execute(); int returnValue = cmd.getInt(1); int UserID = cmd.getInt("UserID"); if(returnValue == 1) { out.print("<li>添加成功！"); out.print("<li>UserID = " + UserID); out.print("<li>returnValue = " + returnValue); } else { out.print("<li>添加失败！"); } f.close();}catch(Exception ex){ out.print(ex.getLocalizedMessage());}finally{ try { if(cmd != null) { cmd.close(); cmd = null; } if(cn != null) { cn.close(); cn = null; } } catch(Exception e) { e.printStackTrace(); }}%></body></html>
