矿山六大系统之人员定位查询

在这里插入图片描述
我要实现的是以上图片的功能
mysql的模块设计：

怎么设置修改一个表中的数据另一个表中相关的数据也更改了？
mysql语句：
UPDATE person_info SET person_info.name=information.name FROM person_info,information WHERE person_info .num=information.num

改良：在实际操作中是用不到那么多查询的，更多的是 名称 编号 机构 时间
时间区间查询的sql语句：
在这里插入图片描述

这个功能涉及到两张表

在这里插入图片描述
所有涉及数据库的无非就是sql语句的问题，增删改查

查询表中不重复的数据：
SELECT DISTINCT part FROM person_info
我的sql语句思路如下：

//根据名字查询+时间
SELECT number FROM person_info WHERE NAME=‘田江南’
SELECT * FROM yh WHERE TIME BETWEEN ‘2018-09-28 14:00:00’ AND ‘2018-09-28 18:00:00’ WHERE number=’’;

//根据number查询+时间
SELECT * FROM yh WHERE TIME BETWEEN ‘2018-09-28 14:00:00’ AND ‘2018-09-28 18:00:00’ WHERE number=’’;

//根据机构查询+时间
SELECT number FROM person_info WHERE part=‘公司’
SELECT * FROM yh WHERE TIME BETWEEN ‘2018-09-28 14:00:00’ AND ‘2018-09-28 18:00:00’ WHERE number=’’;

//根据名字+number查询
SELECT number FROM person_info WHERE NAME=‘田江南’
IF(number==所获取到的number是否一致){一致就执行下一句；不一致返回错误信息，名称与编号不一致}
SELECT * FROM yh WHERE TIME BETWEEN ‘2018-09-28 14:00:00’ AND ‘2018-09-28 18:00:00’ WHERE number=’’;

//根据名称和机构也是一样的

//根据机构和number也是一样的
jsp页面的设计：
1.在点击提交按钮的时候，如果时间是空的话就提示不可为空！
开始时间和结束时间都要填；
js代码如下

<script type="text/javascript">
	function checktime() {
		var stime=document.getElementById("stime").value;
		var etime=document.getElementById("etime").value;
		var submit=document.getElementById("submit");
		if(stime!=null&&etime!=null&&stime!=""&&etime!=""){
		submit.setAttribute("type","submit");
		document.getElementById("error_info").innerHTML="";
		}else{
		submit.setAttribute("type","button");
		document.getElementById("error_info").innerHTML="开始时间和结束时间不能为空";
		}
	}
	</script>

相关jsp代码如下：

<span class="peo_left">开始时间:<input type="text"  name="stime" id="stime" placeholder="年年年年-月月-日日 时时:分分:秒秒" /></span>
<span id="error_info" style="color:red;"></span>
<br>
<span class="peo_left">结束时间:<input type="text"  name="etime" id="etime"  placeholder="年年年年-月月-日日 时时:分分:秒秒" /></span>
<input type="button" value="查询" class="select" id="submit" onclick="checktime();"/>

2.选择部门的时候，就是查询表部门里面所有的名称；
在这个页面加载的时候就应该出现；

package cn.com.servlet;

import java.io.IOException;
import java.io.PrintWriter;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.util.ArrayList;
import java.util.List;

import javax.servlet.ServletException;
import javax.servlet.http.HttpServlet;
import javax.servlet.http.HttpServletRequest;
import javax.servlet.http.HttpServletResponse;

import cn.com.lf.JdbcUtils;

public class All_Part extends HttpServlet {
	public void doGet(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {

	doPost(request, response);
	}


	public void doPost(HttpServletRequest request, HttpServletResponse response)
			throws ServletException, IOException {
    //查询所有部门的名称
		String sql="SELECT DISTINCT part FROM person_info" ;
		ResultSet rs=JdbcUtils.select(sql, null);
		List<String> list=new ArrayList<String>();
		try {
			while(rs.next()){
				list.add(rs.getString(1));
	
			}
			request.setAttribute("alllist", list);
			request.getRequestDispatcher("/SearchPosition.jsp").forward(request, response);
		} catch (SQLException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}

	
}

相关jsp代码

<span class="peo_left">所属机构:
<select>
<option>请选择</option>
 <c:forEach items="${alllist}" var="i"  varStatus="status">
<option>${i}</option>
</c:forEach>
</select>
</span>

历时6个小时终于结束了：
