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 ->SetQuery( $sql ); //格式化查询语句
$dsql ->ExecNoneQuery(); //执行SQL操作
经实践证明，上面的语句不能正常插入数据库，下面是正确的语句
$sql = "
INSERT INTO `dede_member_flink`(mid,title,url,linktype,imgurl,imgwidth,imgheight)
VALUES( ".$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();
