織夢dedecms的數據庫操作類，非常實用，在二次開發中尤其重要，這個數據庫操作類說明算是奉獻給大家的小禮物了。
引入common.inc.php文件
require_once (dirname(__FILE__) . "/include/common.inc.php");
獲取一條記錄的內容
$row = $dsql->GetOne("Select * From dede_* where id = $aid");
echo $row['id'];
將查詢獲取總數輸出
$row = $dsql->GetOne("select count(*) as dd where typeid = $typeid");
echo $row['dd'];//輸出總數
將查詢的若干條記錄輸出
$sql = "Select * from dede_*";
$dsql->SetQuery($sql);//將SQL查詢語句格式化
$dsql->Execute();//執行SQL操作
//通過循環輸出執行查詢中的結果
while($row = $dsql->GetArray()){
echo $row['id'];
echo $row['title'];
}
//或者采取這種方式輸出內容
while($row = $dsql->GetObject()){
echo $row->id;
echo $row->Title;
}
將查詢的若干條記錄輸出dedecms5
$dsql->SetQuery("Select id,typename From `dede_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;
}
插入一條記錄
$sql = "
INSERT INTO `dede_member_flink`(mid,title,url,linktype,imgurl,imgwidth,imgheight)
VALUES(".$cfg_ml->M_ID.",'$title','$url','$linktype','$imgurl','$imgwidth','$imgheight');";//插入記錄數據庫
$dsql->SetQuery($sql);//格式化查詢語句
$dsql->ExecNoneQuery();//執行SQL操作
經實踐證明，上面的語句不能正常插入數據庫，下面是正確的語句
$sql = "
INSERT INTO `dede_member_flink`(mid,title,url,linktype,imgurl,imgwidth,imgheight)
VALUES(".$cfg_ml->M_ID.",'$title','$url','$linktype','$imgurl','$imgwidth','$imgheight');";//插入記錄數據庫
$dsql->ExecuteNoneQuery($sql);//執行SQL操作
$gid = $dsql->GetLastID();//獲取剛剛插入的id
刪除一條記錄
$sql = "Delete From dede_member_flink where aid='$aid' And mid='".$cfg_ml->M_ID."';";
$dsql->SetQuery($sql);
$dsql->ExecNoneQuery();
//或者使用簡化模式
$dsql->ExecNoneQuery("Delete From dede_member_flink where aid='$aid' And mid='".$cfg_ml->M_ID."';");
更新一條記錄
$upquery = "
Update dede_member_flink set
title='$title',url='$url',linktype='$linktype',
imgurl='$imgurl',imgwidth='$imgwidth',imgheight='$imgheight'
where aid='$aid' And mid='".$cfg_ml->M_ID."';
";
$rs = $dsql->ExecuteNoneQuery($upquery);
判斷獲取數據庫內容的常用方法
$row = $dsql->GetOne("Select * From dede_moneycard_type where tid={$pid}");
if(!is_array($row)){
echo "失敗";
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 "失敗";
}
獲取總數
$dsql = new DedeSql(false);
$dsql->SetQuery("Select * from `dede_admin` where userid='$userid' Or uname='$uname'");
$dsql->Execute();
$ns = $dsql->GetTotalRow();
