dedecms的数据库操作类，非常实用，在二次开发中尤其重要。
引入common.inc.php文件require_once (dirname(__FILE__) . "/include/common.inc.php");获取一条记录的内容$row = $dsql->GetOne("Select * From `blog_arctype` where id = $aid");echo $row['id'];将查询获取总数输出$row = $dsql->GetOne("select count(*) as dd where typeid = $typeid");echo $row['dd'];//输出总数将查询的若干条记录输出$sql = "Select * from blog_*";$dsql->SetQuery($sql);
//将SQL查询语句格式化$dsql->Execute();//执行SQL操作//通过循环输出执行查询中的结果while($row = $dsql->GetArray()){echo $row['id'];echo $row['title'];}//或者采取这种方式输出内容while($row = $dsql->GetObject()){echo $row->id;echo $row->Title;}将查询的若干条记录输出$dsql->SetQuery("Select id,typename From `blog_arctype` where reid=0 And channeltype=1 And ishidden=0 And ispart<>2 order by sortrank");$dsql->Execute();while($row=$dsql->GetObject()){ $channellist .= "<a href='wap.php?action=list&id={$row->id}'>{$row->typename}</a> "; echo $row->id;}
插入一条记录$sql = "INSERT INTO `blog_member_flink`(mid,title,url,linktype,imgurl,imgwidth,imgheight)VALUES(".$cfg_ml->M_ID.",'$title','$url','$linktype','$imgurl','$imgwidth','$imgheight');";//插入记录数据库$dsql->ExecuteNoneQuery($sql);//执行SQL操作$gid = $dsql->GetLastID();//获取刚刚插入的id删除一条记录$sql = "Delete From blog_member_flink where aid='$aid' And mid='".$cfg_ml->M_ID."';";$dsql->SetQuery($sql);$dsql->ExecNoneQuery();//或者使用简化模式$dsql->ExecNoneQuery("Delete From blog_member_flink where aid='$aid' And mid='".$cfg_ml->M_ID."';");更新一条记录$upquery = "Update blog_member_flink set
