Question

更新：此问题已在评论中得到解决，正在等待答案

在PyMySQL中执行以下查询时，收到错误“1064, u"You have an error in your SQL syntax;”（下面的完整错误消息）

INSERT INTO `table_name` (`id`, `colName1`, `colName2`, `colName3`) 
VALUES (820, 'string', 5, 'N')
ON DUPLICATE KEY UPDATE
    `colName1`=VALUES(`colName1`),
    `colName2`=VALUES(`colName2`),
    `colName3`=VALUES(`colName3`)
-- Tried with and without ` surrounding column names after ON DUPLICATE KEY UPDATE

Python语法：

sql = "INSERT INTO `table_name` (`id`, `colName1`, `colName2`, `colName3`) VALUES (820, 'string', 5, 'N') ON DUPLICATE KEY UPDATE `colName1`=VALUES(`colName1`),`colName2`=VALUES(`colName2`),`colName3`=VALUES(`colName3`)"

我在尝试使用接受答案的格式更新多行（suggested elsewhere时）以及一次更新一行时都收到此错误。

如评论中所述，精简示例未产生错误（尽管未使用Python执行）。以下是实际查询。如果需要其他信息，请告诉我。

在Python中执行的查询字符串：

INSERT INTO `Listings` (`id`, `row_last_updated`, `maxBidCountPreRsvMet`, `maxBidPreRsvMet`, `minBidCountPostRsvMet`, `occupancy_status`, `waitingForHnb`, `ownItNow_price`, `high_bid`, `prop_id`, `hot_property`, `status`, `end_date`, `reserve_met`, `hours`, `backupBidSet`, `listing_type`, `low_bid`, `winning_bid`, `bids`, `days`, `high_bid_updated`, `minutes`, `lowBidIsOpt1`) VALUES (820, '2018-01-28 19:16:02', '5', '234000', None, 'N', None, 0, 234000, u'9007092665103', 'N', 'New', '2018-1-31-22-0', 'N', 7, 0, 'AUCN', 0, 0, 5, 3, '2018-01-28 14:16:02.001906', 44, 0) ON DUPLICATE KEY UPDATE `row_last_updated`=VALUES(`row_last_updated`),`maxBidCountPreRsvMet`=VALUES(`maxBidCountPreRsvMet`),`maxBidPreRsvMet`=VALUES(`maxBidPreRsvMet`),`minBidCountPostRsvMet`=VALUES(`minBidCountPostRsvMet`),`occupancy_status`=VALUES(`occupancy_status`),`waitingForHnb`=VALUES(`waitingForHnb`),`ownItNow_price`=VALUES(`ownItNow_price`),`high_bid`=VALUES(`high_bid`),`prop_id`=VALUES(`prop_id`),`hot_property`=VALUES(`hot_property`),`status`=VALUES(`status`),`end_date`=VALUES(`end_date`),`reserve_met`=VALUES(`reserve_met`),`hours`=VALUES(`hours`),`backupBidSet`=VALUES(`backupBidSet`),`listing_type`=VALUES(`listing_type`),`low_bid`=VALUES(`low_bid`),`winning_bid`=VALUES(`winning_bid`),`bids`=VALUES(`bids`),`days`=VALUES(`days`),`high_bid_updated`=VALUES(`high_bid_updated`),`minutes`=VALUES(`minutes`),`lowBidIsOpt1`=VALUES(`lowBidIsOpt1`)

完整的错误消息： (1064, u"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 ''9007092665103', 'N', 'New', '2018-1-31-22-0', 'N', 7, 0, 'AUCN', 0, 0, 5, 3, '2' at line 1")

附注：Python None值转换为MySQL null值。将None值更改为字符串时发生相同的错误。

这个ON DUPLICATE KEY UPDATE查询的语法错误是什么？
