安卓(java)連接sqlserver 執行存儲過程步驟

1>帶參數的新增用戶存儲過程：

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

2>不帶參數的查詢用戶信息存儲過程：

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

3>帶參數有輸出參數的存儲過程：

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>做好準備工作之後新建java項目，導入sqljdbc.jar


package com.Project_DataBase01;

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

public class SelectQuery {

    private Connection conn;

    /*
     * 創建一個返回Connection的方法
     */
    public Connection getConnection(){
        try {
            Class.forName("com.microsoft.sqlserver.jdbc.SQLServerDriver");
            System.out.println("數據庫驅動加載成功");
            conn=DriverManager.getConnection("jdbc:sqlserver://localhost:1433;DatabaseName=java_conn_test","sa","123456");
            if(conn==null){
                System.out.println("數據庫連接失敗");
                System.out.println("-----------------------");
            }else {
                System.out.println("數據庫連接成功");
                System.out.println("-----------------------");
            }
        } catch (Exception e) {
            // TODO: handle exception
            e.printStackTrace();
        }
        return conn;
    }

}

5>執行存儲過程：

    }

            }
        }
    }

    /*

    public static void GetProduseInsert(){
        if(conn==null){

                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("添加失敗");
             }
        }
    }

                sp.registerOutParameter(2, Types.INTEGER);
                sp.execute();
                System.out.println("查詢成功:"+sp.getInt(2));

由於jdbc 連接返回的對象都是將ResultSet對象,類似java中結果集,所以使用起來不太方便,老是,容易出錯,造成代碼累贅,這裏給出一個將ResultSet轉換成我們常用的json字符串類型的方法,這樣我們就可以將請求到的數據ResultSet轉換成json字符串,再用監聽者模式回調到主線中中,再進行處理我們就熟悉多了.

 /**
     * 將ResultSet  轉換成JsonArray
     *
     * @param rs
     * @return
     * @throws SQLException
     * @throws JSONException
     */
    public static JSONArray resultSetToJsonArry(ResultSet rs) throws SQLException, JSONException {
        // json數組
        JSONArray array = new JSONArray();
        // 獲取列數
        ResultSetMetaData metaData = rs.getMetaData();
        int columnCount = metaData.getColumnCount();
        // 遍歷ResultSet中的每條數據
        while (rs.next()) {

            JSONObject jsonObj = new JSONObject();
            // 遍歷每一列

            for (int i = 1; i <= columnCount; i++) {

                String columnName = metaData.getColumnLabel(i);

                String value = rs.getString(columnName);

                jsonObj.put(columnName, value);

            }
            array.put(jsonObj);
        }
        return array;

    }

我在代碼中使用的是jtds-1.2.jar 這個跟jdbc類似,哪裏不一樣還沒看,先做一個記錄,這個jar包我也上傳到我的csdn了,存儲起來以便於以後再次的使用,還有jdbc.jar也一併上傳,看看你們需要哪個,需要那個沒去下載使用吧,
