الإستعلامات وسؤال آخر

[LATE]

السلام عليكم

عملت الاستعلام التالي :

		$query0 = "SELECT pagetext,postid,dateline,iconid FROM post WHERE threadid='$thread[threadid]' ORDER BY dateline LIMIT 1";
		$lastpost = mysql_query($query0) or die("MySQL reported this error while trying to retrieve the last post info: ".mysql_error());
		while ($lastpost1 = mysql_fetch_array($lastpost)) {
		$lastpostshort = $lastpost1[pagetext];
		$lastpostshort = nl2br($lastpostshort);
		$lastpostshort = str_replace("","<i>",$lastpostshort);
		$lastpostshort = str_replace("","</i>",$lastpostshort);
		$lastpostshort = str_replace("","<u>",$lastpostshort);
		$lastpostshort = str_replace("","</u>",$lastpostshort);
		$lastpostshort = str_replace("","<b>",$lastpostshort);
		$lastpostshort = str_replace("","</b>",$lastpostshort);
		$lastpostshort = str_replace("","<i>",$lastpostshort);
		$lastpostshort = str_replace("","</i>",$lastpostshort);
		$lastpostshort = str_replace("","<u>",$lastpostshort);
		$lastpostshort = str_replace("","</u>",$lastpostshort);
		$lastpostshort = str_replace("","<b>",$lastpostshort);
		$lastpostshort = str_replace("","</b>",$lastpostshort);
		$lastpostshort = str_replace("[img]","<img border=\"0\" src=\"",$lastpostshort);
		$lastpostshort = str_replace("[/img]","\">",$lastpostshort);
		$lastpostshort = str_replace("[IMG]","<img border=\"0\" src=\"",$lastpostshort);
		$lastpostshort = str_replace("[/IMG]","\">",$lastpostshort);
		$lastpostshort = str_replace("http://","",$lastpostshort);<br />
... str_replace("","",$lastpostshort);
		$lastpostshort = str_replace("http://","",$lastpostshort);<br />
... str_replace("","",$lastpostshort);
	  }

ولله الحمد نجح
فقمت بالتالي :

		$query20 = "SELECT pagetext,postid,dateline,iconid FROM post WHERE threadid='$thread[threadid]'  ORDER BY dateline DESC LIMIT 2";
		$lastpost10 = mysql_query($query20) or die("MySQL reported this error while trying to retrieve the last post info: ".mysql_error());
		while ($lastpost30 = mysql_fetch_array($lastpost10)) {
		$lastpostshort10 = $lastpost30[pagetext];
		$lastpostshort10 = nl2br($lastpostshort10);
		$lastpostshort10 = str_replace("","<i>",$lastpostshort10);
		$lastpostshort10 = str_replace("","</i>",$lastpostshort10);
		$lastpostshort10 = str_replace("","<u>",$lastpostshort10);
		$lastpostshort10 = str_replace("","</u>",$lastpostshort10);
		$lastpostshort10 = str_replace("","<b>",$lastpostshort10);
		$lastpostshort10 = str_replace("","</b>",$lastpostshort10);
		$lastpostshort10 = str_replace("","<i>",$lastpostshort10);
		$lastpostshort10 = str_replace("","</i>",$lastpostshort10);
		$lastpostshort10 = str_replace("","<u>",$lastpostshort10);
		$lastpostshort10 = str_replace("","</u>",$lastpostshort10);
		$lastpostshort10 = str_replace("","<b>",$lastpostshort10);
		$lastpostshort10 = str_replace("","</b>",$lastpostshort10);
		$lastpostshort10 = str_replace("[img]","<img border=\"0\" src=\"",$lastpostshort10);
		$lastpostshort10 = str_replace("[/img]","\">",$lastpostshort10);
		$lastpostshort10 = str_replace("[IMG]","<img border=\"0\" src=\"",$lastpostshort10);
		$lastpostshort10 = str_replace("[/IMG]","\">",$lastpostshort10);
		$lastpostshort10 = str_replace("http://","",$lastpostshort10);<br />... str_replace("","",$lastpostshort10);
		$lastpostshort10 = str_replace("http://","",$lastpostshort10);<br />... str_replace("","",$lastpostshort10);
		  }

وأيضاً نجح ودون مشاكل

ولكن واجهتني مشكله
في حال كان pagetext هو نفسه تظهر النتيجه متكرره
اي ان threadid من خلال الجدول يرتبط فقط في postid واحد

هل هناك شرط مكن الممكن وضعه لمعرفة اذا كانت نتيجة الاستعلام تحمل اكثر من pagetext واحد او واحد فقط ؟

على الله يكون السؤال واضح

[all-the-vb]

والله مافهمت سؤالك عدل

اذا كنت تقصد اذا كان ناتج الاستعلام واحد او اكثر

$r=mysql_num_rows($query20) ;
if($r ==1){
//
}elseif($r > 1){
//
}

سلام عليكم

اعيد السؤال ببساطه

الاستعلام الاول استخدمت فيه التالي :

ORDER BY dateline LIMIT 1 

الاستعلام الثاني استخدمت فيه التالي :

ORDER BY dateline DESC LIMIT 2 

المشكله اذا كانت النتيجه في كلا الاستعلامين واحده فانها تتكرر ..

اريد ان اتخلص من التكرار فقط
