关于sqlserver、access、mysql数据库性能的一个简单测试

本人因为好奇加想验证，对sql server access mysql三款数据库性能进行一个简单测试。

测试方法如下：

建立数据库字段为：

sql server:

access:

mysql:

代码如下：

asp.net+sql server

 int len = 10000;
        DateTime begin = DateTime.Now;
        string sql;
        for (int i = 0; i < len; i++)
        {
            sql = "insert into art (title,content0,hits) values( 'title" + i + "','content" + i + "'," + i + ")";
            DbHelperSQL.ExecuteSql(sql);

        }
        for (int i = 0; i < len; i++)
        {
            sql = "select * from  art where hits=" + (i) + " order by id desc";
            DataTable dt = DbHelperSQL.Query(sql).Tables[0];          

        }

        Response.Write("<div>写" + len + "条，共" + DbHelperSQL.GetSingle("select count(*) from art") + "条用时：" + (DateTime.Now - begin).TotalSeconds + "</div>");

int len = 100;
        DateTime begin = DateTime.Now;
        string sql;
        for (int i = 0; i < len; i++)
        {
            sql = "insert into art (title," + i + ")";
            DbHelperOleDb.ExecuteSql(sql);

        }
        for (int i = 0; i < len; i++)
        {
            sql = "select * from  art where hits=" + i + " order by id desc";
            DataTable dt = DbHelperOleDb.Query(sql).Tables[0];
        
        }

        Response.Write("<div>用时：" + (DateTime.Now - begin).TotalSeconds + "</div>");

public function index()
	{
		set_time_limit(0); 
		$len=10000;
		$pagestartime=microtime();
		for($i=0;$i<$len;$i++)
		{
			$data['title']="title".$i;
			$data['content']="content".$i;
			$data['hits']=$i;
			FDB::insert("art",$data);			
		}		
		for($i=0;$i<$len;$i++)
		{
			$sql ="select * from fanwe_art order by id desc limit $i,1";
			$data=FDB::fetchFirst($sql);			
		}
		$pageendtime = microtime();
		$starttime = explode(" ",$pagestartime);
		$endtime = explode(" ",$pageendtime);
		$totaltime = $endtime[0]-$starttime[0]+$endtime[1]-$starttime[1];
		$timecost = sprintf("%s",$totaltime);
		echo $len."页面运行时间: $timecost 秒";
