asp.net技巧:asp.net管理mysql数据库的小工具ASP.NET

【无忧考网-asp技巧:asp管理mysql数据库的小工具】：

一、打开mysql数据库： MySqlConnection DBConn = new MySqlConnection(); string connString ="Host=127.0.0.1;UserName=root;PassWord=root;Database=test;Port=3306;CharSet=utf8;Allow Zero Datetime=true"; DBConn.ConnectionString = connString; DBConn.Open();

二、执行sql命令 string sqlstr="select * from test"; MySqlCommand command = new MySqlCommand(sqlstr, DBConn); command.ExecuteNonQuery();

从上面可以看出，用法跟操作SQL数据库的SqlConnection、SqlCommand非常相似，下面我这里有一个完整的例子来实现对mysql数据库进行管理，包括浏览表结构和数据、查询-修改-插入-删除数据，导出数据和表结构等，供大家参考和互相学习。代码写得不规范，还请大家指正。 <%@ Page Language="C#" %> <%@ Import Namespace="System.Data" %> <%@ Import Namespace="System.IO" %> <%@ Import Namespace="System.Text" %> <%@ Import Namespace="MySql.Data.MySqlClient" %> shouji138 MYSQL Manager (DoNet)

选择数据库：

<%if (Session["dbname"] != null && Session["dbname"].ToString() != string.Empty) { %> 当前数据库: <%=dbname.Value %> <% } %> <%if (Request.QueryString["tblname"] != null) { %> | 当前表: "> <%=Request.QueryString["tblname"] %> [ ">添加 | ">结构 | " onclick="return confirm('确定删除表“<%=Request.QueryString["tblname"] %>”?')"> 删除表 ] <% } %>

数据库已经导出为

运行SQL语句 :

<% DataTable dColumn = RunTable(sql_query.Value); %> <% for (int i = 0; i < dColumn.Columns.Count; i++) { %> <% } %> <% DataTable dData = dColumn;

for (int i = 0; i < dData.Rows.Count; i++) { %>

" onmouSEOver="this.className='focus';" onmouseout="this.className='alt<%=i%2==0?"1":"2" %>';"> <% for (int j = 0; j < dData.Columns.Count; j++) { %> <% } %> <% } %>

<%= dColumn.Columns[i].Caption%>

<%= dData.Rows[i][j].ToString()%>

运行的SQL : <%=sql_query.Value%> <% for (int i = 0; i < tblsDt.Rows.Count; i++) { tblRowsCount += int.Parse(tblsDt.Rows[i]["Rows"].ToString()); tblsCount++; tblDbSize += float.Parse(tblsDt.Rows[i]["Data_length"].ToString()); %> "> <% } %>

	Name	Rows	Data_length	Create_time	Update_time
" />	"> <%= tblsDt.Rows[i]["Name"]%> [ ">添加 \| "> 结构 \| " onclick="return confirm('确定删除表“<%= tblsDt.Rows[i]["Name"]%>”？')"> 删除表 ]	<%= tblsDt.Rows[i]["Rows"]%>	<%= showSize(float.Parse(tblsDt.Rows[i]["Data_length"].ToString()))%>	<%= tblsDt.Rows[i]["Create_time"]%>	<%= tblsDt.Rows[i]["Update_time"]%>
	合计：<%= tblsCount%>	<%= tblRowsCount%>	<%= showSize(tblDbSize)%>
保存为文件

<% DataTable dColumn = TableColumn(Request.QueryString["tblname"].ToString().Trim()); for (int i = 0; i < dColumn.Rows.Count; i++) { %> <% } %> <% DataTable dData = RunTable(sql_query.Value); string tblPkName = FindPK(Request.QueryString["tblname"].ToString().Trim()); for (int i = 0; i < dData.Rows.Count; i++) { %> " onmouseover="this.className='focus';" onmouseout="this.className='alt<%=i%2==0?"1":"2" %>';"> <% for (int j = 0; j < dData.Columns.Count; j++) { %> <% } %> <% } %>

Action	<%= dColumn.Rows[i][0]%> <%= dColumn.Rows[i][1]%>
<%if (tblPkName != string.Empty) {%> &pk=<%=tblPkName %>&v=<%=dData.Rows[i][tblPkName] %>"> 编辑 \| &pk=<%=tblPkName %>&v=<%=dData.Rows[i][tblPkName] %>" onclick="return confirm('确定删除该记录？')">删除 <% } %>	<%= dData.Rows[i][j]%>

在表<%=Request.QueryString["tblname"].Trim() %>中编辑记录 »

<% DataTable dColumn = TableColumn(Request.QueryString["tblname"].ToString().Trim()); DataTable editData = RunTable("select * from " + Request.QueryString["tblname"].ToString() + " where " + Request.QueryString["pk"].ToString() + " = " + Request.QueryString["v"].ToString() + "");

if (editData.Rows.Count > 0) { for (int i = 0; i < dColumn.Rows.Count; i++) { %>

" onmouseover="this.className='focus';" onmouseout="this.className='alt<%=i%2==0?"1":"2" %>';"> <% } %> <% } %>

<%= dColumn.Rows[i][0]%> <%= dColumn.Rows[i][1]%>	<%=editData.Rows[0][dColumn.Rows[i][0].ToString().Trim()]%>

在表<%=Request.QueryString["tblname"].Trim() %>中添加记录 »

<% DataTable dColumn = TableColumn(Request.QueryString["tblname"].ToString().Trim());

表<%=Request.QueryString["tblname"].Trim() %>的结构 »
