將訂單添加到SELECT請求

Question

我想訂購我的結果，並得到一個TString錯誤。有人可以告訴我在哪裏或如何添加ORDER BY date DESC, paymentamount DESC這樣：

$sql = "SELECT * FROM `Carriers` WHERE fromzip >= '".mysql_real_escape_string($_REQUEST["from"])."'".$search_string.$search_loadtype; 

這是我曾嘗試與它沒有讓我：

$sql = "SELECT * FROM `Carriers` WHERE fromzip >= '".mysql_real_escape_string($_REQUEST["from"])."'".$search_string.$search_loadtype ORDER BY date DESC, paymentamount DESC; 

Answer 1

試試這個..

$sql = "SELECT * FROM `Carriers` WHERE fromzip >= '".mysql_real_escape_string($_REQUEST["from"])."'".$search_string.$search_loadtype." ORDER BY date DESC, paymentamount DESC"; 

您需要使用（。）將字符串值拼湊在一起。然後你沒有帶開了字符串引號...

變爲

$search_loadtype." ORDER BY 

Answer 2

我認爲你錯過了一些報價：

$sql = "SELECT * FROM `Carriers` WHERE fromzip >= '".mysql_real_escape_string($_REQUEST["from"])."'".$search_string." ".$search_loadtype." ORDER BY date DESC, paymentamount DESC"; 

Answer 3

在我看來，你有語法錯誤，我無法真正知道$ search_string和$ search_loadtype包含在您的代碼中，但請進行以下嘗試...

$sql = "SELECT * FROM `Carriers` WHERE fromzip >= '".mysql_real_escape_string($_REQUEST["from"])."'".$search_string.$search_loadtype . " ORDER BY date DESC, paymentamount DESC;";
