Dedecms 獲得頂級欄目名稱的SQL語句

 引用的內容：
{dede:field.typeid runphp=’yes’}$ID = @me; $sql = "SELECT `reid` FROM `dede_arctype` WHERE id=$ID";$query = mysql_query($sql);$row=mysql_fetch_array($query); $relID = "$row[reid]";$sql2 = "SELECT `typename` FROM `dede_arctype` WHERE id=$relID";$query2 = mysql_query($sql2);$row2=mysql_fetch_array($query2); @me = $row2[typename];{/dede:field.typeid}

上面那個不是很完善，當欄目本來就是頂級欄目時就得不到了，用這個吧
 引用的內容： 
{dede:field.typeid runphp=’yes’}$ID = @me; $sql = "SELECT * FROM `dede_arctype` WHERE id=$ID";$query = mysql_query($sql);$row=mysql_fetch_array($query); $relID = "$row[reid]"; if($relID == 0) {@me = $row[typename];}else{$sql = "SELECT `typename` FROM `dede_arctype` WHERE id=$relID";$query = mysql_query($sql);$row=mysql_fetch_array($query); @me = $row[typename];}{/dede:field.typeid}
 

dede5.5在列表頁和內容頁調用頂級欄目名稱方法

{dede:field.typeid  runphp=’yes’ function="GetTopid(@me)"}

$dsql = new DedeSql(false);

$a="SELECT  typename FROM dede_arctype  where id=@me";

$arcRow = $dsql->GetOne($a);

@me=$arcRow[typename];{/dede:field.typeid}
