dedecms织梦数据库类使用方法$dsql

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
