Question

我有一张这样的桌子：

    CREATE TABLE `tblinquiries` (
  `UID` varchar(50) DEFAULT NULL,
  `ReviewDate` date NOT NULL,
  `InquiryId` varchar(50) DEFAULT NULL,
  `AuditStatus` varchar(50) DEFAULT NULL,
  PRIMARY KEY (`InquiryId`)
) ENGINE=InnoDB DEFAULT CHARSET=latin1;

我有一个带数据的csv文件：

UID,ReviewDate,InquiryId,AuditStatus

UID1,2018-07-06,109814969,Check

UID2,2018-07-06,109866072,Check

UID3,2018-07-06,109911408,Check

UID4,2018-07-06,109798278,Check

我使用以下命令上传数据：

   $location = '../uploads/';
   $name = $_FILES["file"]["name"];
   $filePath = $location.$name;
   $table = 'tblinquiries';

   LOAD DATA LOCAL INFILE "'.$filePath.'"
   INTO TABLE '.$table.'
   FIELDS TERMINATED by \',\' OPTIONALLY ENCLOSED BY \'"\'
   LINES TERMINATED BY \'\n\'
   IGNORE 1 LINES

它将上传数据，但在第二行添加额外的字符“ \ r”。我导出了数据，结果如下：

('UID4', '2018-07-06', '109798278', 'Check'),
('UID1', '2018-07-06', '109814969', 'Check\r'),
('UID2', '2018-07-06', '109866072', 'Check\r'),
('UID3', '2018-07-06', '109911408', 'Check\r');

运行后：

SELECT AuditStatus, LENGTH(AuditStatus) FROM `tblinquiries`

得到：

AuditStatus LENGTH(AuditStatus)
Check          5
Check          6
Check          6
Check          6

我该如何解决？

Answer 1

我认为您的源数据具有这些\r控制字符，因为LOAD DATA通常不会将数据添加到源文件中（除非您告知这样做，否则不会出现）就是这种情况）。我们可以尝试在RTRIM列上运行AuditStatus：

LOAD DATA LOCAL INFILE "'.$filePath.'"
INTO TABLE '.$table.'
FIELDS TERMINATED by \',\' OPTIONALLY ENCLOSED BY \'"\'
LINES TERMINATED BY \'\n\'
IGNORE 1 LINES
(UID, ReviewDate, InquiryId, @AuditStatus)
SET AuditStatus = RTRIM(@AuditStatus);

Answer 2

正如@Sloan所建议的，我更改了行终止符，从而解决了问题。这是最终代码。

        LOAD DATA LOCAL INFILE "'.$filePath.'"
        INTO TABLE '.$table.'
        FIELDS TERMINATED by \',\' OPTIONALLY ENCLOSED BY \'"\'
        LINES TERMINATED BY \'\r\n\'
        IGNORE 1 LINES

MySQL：LOAD DATA LOCAL INFILE添加了额外的字符'\ r'
