สอบถามเรื่องการใช้ SELECT TOP ใช้แล้วมันติด Error ครับ

	$objConnect = mssql_connect("localhost","sa","") or die("Error Connect to Database");
	$objDB = mssql_select_db("mydatabase");
	// Search By Name or Email
	$strSQL = "SELECT  * FROM customer  WHERE (Name LIKE '%".$_GET["txtKeyword"]."%' or Email LIKE '%".$_GET["txtKeyword"]."%' )  ";
	$objQuery = mssql_query($strSQL) or die ("Error Query [".$strSQL."]");
	$Num_Rows = mssql_num_rows($objQuery);


	$Per_Page = 2;   // Per Page

	$Page = $_GET["Page"];
	if(!$_GET["Page"])
	{
		$Page=1;
	}

	$Prev_Page = $Page-1;
	$Next_Page = $Page+1;

	$Page_Start = (($Per_Page*$Page)-$Per_Page);
	if($Num_Rows<=$Per_Page)
	{
		$Num_Pages =1;
	}
	else if(($Num_Rows % $Per_Page)==0)
	{
		$Num_Pages =($Num_Rows/$Per_Page) ;
	}
	else
	{
		$Num_Pages =($Num_Rows/$Per_Page)+1;
		$Num_Pages = (int)$Num_Pages;
	}
	$Page_End = $Per_Page * $Page;
	IF ($Page_End > $Num_Rows)
	{
		$Page_End = $Num_Rows;
	}
