最近MOMO身心疲惫。。今天是周末在家无聊我还是决定来学习。不知道学什么,就学MySQL吧。本篇主要记录从MySQL安装到局域网内任意机器连接数据库,也算是对自己学习的总结。今天我没用Mac电脑,而是选择Windows,没有别有用心,而是想熟悉一下Windows下操作Unity。
官网上下载MySQL的安装程序,这里有一篇详细的安装文章,http://www.jb51.net/article/23876.htm 为了让中文完美的运行,配置MySQL的时候Character Set处设置成UTF-8,好像默认是不能显示中文。配置完毕后就可以在本机中启动MySQL,也可以在cmd命令行中start和stop 启动与关闭MySQL。
net start mysql
net stop mysql
为了让本机MySQL数据库可以在局域网中任意机器都可以访问,请看 下面这个网址。
http://dzb3688.blog.163.com/blog/static/105068522201292671444891/
文章有一点点讲的不是很清楚,所以我在补充一下、
我用的是Navicat Pewmium查看数据库,我觉得这个数据库挺好的,因为我在Mac上也是用的这个数据库 。(大家可以在网络上下载它,Windows版本居然有汉化的)如下图所示,点击用户,然后双击”root@%” 最后把主机的名字改成 “%”即可、
下面就是重点了,打开cmd 窗口cd到MySQL的路径下,一定要cd到这个路径下,不然mysql 会是无法识别的指令噢。
然后执行命令:
mysql grant all privileges on *.* to root@”%” identified by ‘abc’ with grant option;
flush privileges;
在执行命令:
mysql flush privileges;
OK这样就行了。
然后开始看看代码怎么写,为了方便数据库的创建、增加、删除、修改、查询、我封装了一个类。欢迎大家测试 啦啦啦啦。
SqlAccess.cs

public class SqlAccess
{
public static MySqlConnection dbConnection;
//如果只是在本地的话,写localhost就可以。
// static string host = "localhost";
//如果是局域网,那么写上本机的局域网IP
static string host = "192.168.1.106";
static string id = "root";
static string pwd = "1234";
static string database = "xuanyusong";
public SqlAccess()
{
OpenSql();
}
public static void OpenSql()
{
try
{
string connectionString = string.Format("Server = {0};port={4};Database = {1}; User ID = {2}; Password = {3};",host,database,id,pwd,"3306");
dbConnection = new MySqlConnection(connectionString);
dbConnection.Open();
}catch (Exception e)
{
throw new Exception("服务器连接失败,请重新检查是否打开MySql服务。" + e.Message.ToString());
}
}
public DataSet CreateTable (string name, string[] col, string[] colType)
{
if (col.Length != colType.Length)
{
throw new Exception ("columns.Length != colType.Length");
}
string query = "CREATE TABLE " + name + " (" + col[0] + " " + colType[0];

}
query += ", PRIMARY KEY ("+ col[0] +")" + ")";
Debug.Log(query);
return ExecuteQuery(query);
}
//插入一条数据,包括所有,不适用自动累加ID。
public DataSet InsertInto (string tableName, string[] values)
{
string query = "INSERT INTO " + tableName + " VALUES (" + "'"+ values[0]+ "'";

Debug.Log(query);
return ExecuteQuery (query);
}
public DataSet SelectWhere (string tableName, string[] items, string[] col, string[] operation, string[] values)
{
if (col.Length != operation.Length || operation.Length != values.Length) {
throw new Exception ("col.Length != operation.Length != values.Length");
}
string query = "SELECT " + items[0];
for (int i = 1; i < items.Length; ++i) {

}
public DataSet UpdateInto (string tableName, string []cols,string []colsvalues,string selectkey,string selectvalue)

}
public void Close()
{
if(dbConnection != null)
{
dbConnection.Close();
dbConnection.Dispose();
dbConnection = null;

}
public static DataSet ExecuteQuery(string sqlString)
{
if(dbConnection.State==ConnectionState.Open)
{
DataSet ds = new DataSet();
try
{
MySqlDataAdapter da = new MySqlDataAdapter(sqlString, dbConnection);
da.Fill(ds);
}
catch (Exception ee)
{
throw new Exception("SQL:" + sqlString + "/n" + ee.Message.ToString());
}
finally
{
}
return ds;
}
return null;
}
}
然后在来看看调用,把如下脚本绑定在任意对象即可,调用包括、创建表、插入信息、查找信息、删除信息、更新信息。代码比较简单我就不一一注释了,这里我用try catch如果有错误信息将打印在屏幕中。 创建表包括是否递增ID,所以有两种创建表的方式。如果你的数据库是提前预制的话可以这样来读取数据库。
using UnityEngine;
using System;
using System.Data;
using System.Collections;
using MySql.Data.MySqlClient;
using MySql.Data;
using System.IO;
public class NewBehaviourScript : MonoBehaviour {
string Error = null;
void Start ()
{
try
{
SqlAccess sql = new SqlAccess();
sql.CreateTableAutoID("momo",new string[]{"id","name","qq","email","blog"}, new string[]{"int","text","text","text","text"});
//sql.CreateTable("momo",new string[]{"name","qq","email","blog"}, new string[]{"text","text","text","text"});
sql.InsertInto("momo",new string[]{"name","qq","email","blog"},new string[]{"xuanyusong","289187120","xuanyusong@gmail.com","xuanyusong.com"});
sql.InsertInto("momo",new string[]{"name","qq","email","blog"},new string[]{"ruoruo","34546546","ruoruo@gmail.com","xuanyusong.com"});
DataSet ds = sql.SelectWhere("momo",new string[]{"name","qq"},new string []{"id"},new string []{"="},new string []{"1"});
if(ds != null)
{
DataTable table = ds.Tables[0];
foreach (DataRow row in table.Rows)
{
foreach (DataColumn column in table.Columns)
{
Debug.Log(row[column]);
}
}
}
sql.UpdateInto("momo",new string[]{"name","qq"},new string[]{"'ruoruo'","'11111111'"}, "email", "'xuanyusong@gmail.com'" );
sql.Delete("momo",new string[]{"id","email"}, new string[]{"1","'000@gmail.com'"} );
sql.Close();
}catch(Exception e)
{
Error = e.Message;
}
}
// Update is called once per frame
void OnGUI ()
{
if(Error != null)
{
GUILayout.Label(Error);
}
}
}
然后是用到的dll 一个都不能少,不然会出现各种问题。最后的下载地址我会给出,并且包含这些文件。
为了测试局域网的连接, 我还编译到了Android手机上,在Android上访问这个数据库,也是没问题的。当然手机和电脑用的是同一个wifi网络。 目前这个项目在 Windows 和 Android上都可以很好的运行,我感觉在Mac上和iPhone上应该也木有问题,欢迎大家测试,如果发现在别的平台下有问题请告诉我,我会进一步研究的。 欢迎大家留言,一起学习啦啦啦啦 嘿嘿嘿~~。。

补充一点,虽然报错,程序可以正常执行。比较在意报错的原因
你好,请问你现在找到这个原因了么?
你好 请问你现在问题解决了吗?
請問一下,我的資料庫想要連在虛擬網路上的話,應該怎麼改?
怎么备份数据库!
都过去这么久了,我现在在项目里也碰到这个问题,项目里用到了Vuforia的插件就有这问题,不知道你还记得怎么解决的吗,都不知道能不能看的见啊
这个问题解决了么 我也是用ar无法连接mysql

兄弟,你这问题解决了么?我也遇到了
能不能用MySqlDataReader去读取?和DataSet相比哪个更好呢?
android os 这样连上了。void Start() {StartCoroutine(openSqlConnection1());} IEnumerator openSqlConnection1() { // public static void openSqlConnection1() {print (“Open”); /*string connectionString = “Server = http://www.waixing.com;” “Database = vdate;” “User ID = test;” “Password= 123456;” “Pooling=false”; */ string connectionString = string.Format(“Server = {0}; Database = {1}; User ID = {2}; Password = {3};”,host,database,id,pwd); //dbConnection = new MySqlConnection(connectionString); dbConnection = new MySqlConnection(connectionString); dbConnection.Open(); //openSqlConnection(connectionString); yield return new WaitForSeconds(3); Debug.Log(“Connected to database.”); }

我在Plugins里面去掉system.Drawing.dll了,但是xcode报的错是:cannot use ‘throw’ with exceptions disabled.共有14处报错,都是这个错误。请问这个周末解决啊。。
我是用Xcode6.1.1编译的。
我使用Xcode6.1.1编译的,其他平台没问题才在MAC上做的这些修改。
我的xcode也是6.1.1。。在安卓是没问题的。。也猜不出问题出在了哪里。。
看大家都在纠结说IOS上无法发布(报错:Cross compilation job System.Drawing.dll failed.UnityEngine.UnityException: Failed AOT cross compiler: …………………………),最近专门研究了一下。在Plugins里面去掉system.Drawing.dll保留其他四个,发布Xcode就不会报错了,但是问题来了,Xcode编译的时候又会抛出两个错误,其实是一类错误”Use of undeclared identifier ‘GL_BGRA_EXT’“,找到报错的地方,修改头文件将OpenGLES/ES2/gl.h改成了OpenGLES/ES2/glext.h编译通过。编译通过,亲测没有问题,MySQL数据库可以访问,问题解决。
谢谢回复~
不谢,我还要谢你呢,能帮到其他人就好。
说别人垃圾的时候你做了什么,再好的社会也会漏下几个你这样的没被带走
有解决这个问题么。。。
雨松兄 请问一下在pc上可以 也能build 但一旦切换到web平台就报错 是什么情况
宣老师有unity网游方面客户端与服务器端的教程吗?
我测试了PC,MAC,IOS,ANDROID,目前IOS无法发布(报错:Cross compilation job System.Drawing.dll failed.UnityEngine.UnityException: Failed AOT cross compiler: …………………………)其他的平台都可以运行
“打开cmd 窗口cd到MySQL的路径下,一定要cd到这个路径下,不然mysql 会是无法识别的指令噢。”直接添加到path中就可以识别了,不用每次都这么麻烦“然后开始看看代码怎么写,为了方便数据库的创建、增加、删除、修改、查询、我封装了一个类。欢迎大家测试 啦啦啦啦。”这也算封装????sql就不该用拼接的方式来实现。。。
宣老师,发现个问题,当我执行Updata语句去修改记录的字段有中文字符时候,都变了问号的,但是我已在该字段的整理设置为utf8_general_ci,用Select语句读取就没问题,但是修改就变问号了,希望能指点下。
