我已經梳理了這段代碼，並且不能爲我的生活找到錯誤。這是一個PHP文件，我將作爲cron作業運行以檢查結束的拍賣，並且在拍賣結束時發送一封電子郵件給拍賣所有者，代碼發送一封電子郵件給拍賣名單，但它只是通過1次拍賣循環，我假設這是因爲它在代碼中發現錯誤並且正在死亡但我無法找出錯誤。SQL error - near「at line 1
這裏是代碼的全部...

誰能幫助我弄清楚這是爲什麼只有通過1個成交循環，爲什麼我得到的ER ROR。 SQL Error :: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '' at line 1
在採納了建議並對死亡陳述編號後，我已經縮小了這個問題的範圍。以下是引發錯誤的部分代碼：
//Global variables for Auction listings
$bidmaxquery = "SELECT * FROM bids WHERE listing_id=$listingid ORDER BY bid DESC LIMIT 1";
$bidmax = mysql_query($bidmaxquery) or die('SQL Error 3 :: '.mysql_error());
$bidmaxrow = mysql_fetch_assoc($bidmax);
$highestbid = $bidmaxrow['bid'];
$highestbidderid = $bidmaxrow['user_id'];
$highestbidderquery = "SELECT * FROM settings WHERE user_id=$highestbidderid";
$highestbidder = mysql_query($highestbidderquery) or die('SQL Error 4 :: '.mysql_error());
$highestbidderrow = mysql_fetch_assoc($highestbidder);
$highestbiddername = $highestbidderrow['display_name'];
什麼是1號線？ – 2013-04-28 14:45:33
@echo_me MySQL行1引用查詢的第一行，通常是整個查詢。 – 2013-04-28 14:46:29
你可以通過給SQL錯誤::'消息編號開始。讓它們成爲'SQL Error（1）'，2，3等等。然後你知道哪個是壞的。 – 2013-04-28 14:47:57
