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())
{
$channellist .= "id}'>{$row->typename} ";
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
