织梦 dede runphp=yes SQL语句操作
个人实例dede:channelartlist 下循环出 channel 栏目 中的 文章

dedecms的数据库操作类,非常实用,在二次开发中尤其重要,这个数据库操作类说明算是奉献给大家的小礼物了。
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 dede_* 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 dede_*"; $dsql->SetQuery($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dedecms5
$dsql->SetQuery("Select id,typename From `#@__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
$sql = " INSERT INTO `dede_member_flink`(mid,title,url,linktype,imgurl,imgwidth,imgheight) VALUES(".$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
$sql = "Delete From dede_member_flink where aid='$aid' And mid='".$cfg_ml->M_ID."';"; $dsql->SetQuery($sql); $dsql->ExecNoneQuery(); //或者使用简化模式 $dsql->ExecNoneQuery("Delete From dede_member_flink where aid='$aid' And mid='".$cfg_ml->M_ID."';");
更新一条记录
$upquery = " Update dede_member_flink set title='$title',url='$url',linktype='$linktype', imgurl='$imgurl',imgwidth='$imgwidth',imgheight='$imgheight' where aid='$aid' And mid='".$cfg_ml->M_ID."'; "; $rs = $dsql->ExecuteNoneQuery($upquery);
判断获取数据库内容的常用方法
$row = $dsql->GetOne("Select * From dede_moneycard_type where tid={$pid}"); if(!is_array($row)){ echo "失败"; exit(); } ///////////////////////////// $upquery = " Update dede_member_flink set title='$title',url='$url',linktype='$linktype', imgurl='$imgurl',imgwidth='$imgwidth',imgheight='$imgheight' where aid='$aid' And mid='".$cfg_ml->M_ID."'; "; $rs = $dsql->ExecuteNoneQuery($upquery); if($rs){ echo "成功"; }else{ echo "失败"; }
获取总数
$dsql = new DedeSql(false); $dsql->SetQuery("Select * from `dede_admin` where userid='$userid' Or uname='$uname'"); $dsql->Execute(); $ns = $dsql->GetTotalRow();
关闭数据库
$dsql->Close();
