JAVA使用JDBC技术操作SqlServer数据库执行存储过程

Java使用JDBC技术操作SqlServer数据库执行存储过程：

1.新建SQLSERVER数据库：java_conn_test

2.新建表：tb_User

3.分别新建三个存储过程：

1>带参数的新增用户存储过程：

CREATE PROCEDURE [dbo].[p_Insert_User]
@name nvarchar(50),
@UserPwd nvarchar(50)
AS
BEGIN
INSERT INTO tb_User VALUES(NEWID(),@name,@UserPwd)
END

2>不带参数的查询用户信息存储过程：

CREATE PROCEDURE [dbo].[p_Select_User]
AS
BEGIN
SELECT * FROM tb_User
END

3>带参数有输出参数的存储过程：

CREATE PROCEDURE [dbo].[p_Select_UserCount]
@name nvarchar(50),
@result int output
AS
BEGIN
SELECT @result= COUNT(0) FROM tb_User WHERE @name=UserName
END

4>做好准备工作之后新建java项目，导入sqljdbc.jar

package com.Project_DataBase01;

import java.sql.Connection;
import java.sql.DriverManager;

public class SelectQuery {

private Connection conn;

/*
     * 创建一个返回Connection的方法
*/
public Connection getConnection(){
try {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            System.out.println("数据库驱动加载成功");
            conn=DriverManager.getConnection("jdbc:sqlserver://localhost:1433;DatabaseName=java_conn_test","sa","123456");
if(conn==null){
                System.out.println("数据库连接失败");
                System.out.println("-----------------------");
            }else {
                System.out.println("数据库连接成功");
                System.out.println("-----------------------");
            }
        } catch (Exception e) {
// TODO: handle exception
            e.printStackTrace();
        }
return conn;
    }

}

5>执行存储过程：

package com.Project_DataBase01;

import java.sql.CallableStatement;
import java.sql.Connection;
import java.sql.PreparedStatement;
import java.sql.ResultSet;
import java.sql.Statement;
import java.sql.Types;

public class StartMain {

private static Connection conn;

public static void main(String[] args) {
// TODO Auto-generated method stub
        
        conn=new SelectQuery().getConnection();

        GetProduseInsert();

        GetProduseSelect02();

        GetProduseSelect();

    }

/*
     * 执行SELECT无参数存储过程,查询数据
*/

public static void GetProduseSelect(){
if(conn==null){
            System.out.println("链接数据库失败");
        }else {
try {
                CallableStatement cs=conn.prepareCall("{call p_Select_User()}");
                ResultSet rs=cs.executeQuery();
while (rs.next()) {
                    String name=rs.getString("UserName");
                    String pwd=rs.getString("UserPwd");
                    String UserId=rs.getString("UserId");
                    System.out.println(name+"\t"+pwd+"\t"+UserId);
                }
                System.out.println("查询成功");
                System.out.println("-----------------------");
            } catch (Exception e) {
// TODO: handle exception
                System.out.println("查询失败");
                System.out.println("-----------------------");
            }
        }
    }

/*
     *执行INSERT有参数存储过程,查询数据 
*/
public static void GetProduseInsert(){
if(conn==null){
            System.out.println("数据库连接失败");
        }else {
try {
                CallableStatement ic=conn.prepareCall("{call p_Insert_User(?,?)}");
                ic.setString(1, "heyangyi");
                ic.setString(2, "123");
                ic.execute();
                System.out.println("添加成功");
             }
catch (Exception ex) {
//TODO: handle exception
                 System.out.println("添加失败");
             }
        }
    }

/*
     * 执行带输出参数的存储过程
*/
public static void GetProduseSelect02(){
if(conn==null){
            System.out.println("数据库链接失败");
        }else {
try {
                CallableStatement sp=conn.prepareCall("{call p_Select_UserCount(?,?) }");
                sp.setString(1,"heyangyi");
                sp.registerOutParameter(2, Types.INTEGER);
                sp.execute();
                System.out.println("查询成功:"+sp.getInt(2));
            } catch (Exception e) {
// TODO: handle exception
                System.out.println("查询失败");
            }
        }
    }
}
