Question

我正在开发一个新项目，一个PHP中的Web应用程序，需要用户输入可能很大的数据集。我的解决方案是让用户上传一个csv文件，然后使用LOAD DATA INFILE命令将其添加到我的mysql数据库。

我的测试csv：

NUMBER,ADDRESS,COMMENT,SCOUTMASTER_NAME,SCOUTMASTER_EMAIL,COMMITTEE_NAME,COMMITTEE_EMAIL,DISTRICT
4,404 test st.,so cool,bob jones,bob@jones.com,tim hanson,tim@hanson.net,western trails
5,404 test st.,so cool,bob jones,bob@jones.com,tim hanson,tim@hanson.net,western trails
6,404 test st.,so cool,bob jones,bob@jones.com,tim hanson,tim@hanson.net,western trails
7,404 test st.,so cool,bob jones,bob@jones.com,tim hanson,tim@hanson.net,western trails

DESCRIBE表上TROOPS命令的结果：

+---------------------+---------------+------+-----+---------+-------+
| Field               | Type          | Null | Key | Default | Extra |
+---------------------+---------------+------+-----+---------+-------+
| NUMBER              | int(11)       | NO   | PRI | 0       |       |
| ADDRESS             | varchar(255)  | YES  |     | NULL    |       |
| COMMENT             | varchar(2048) | YES  |     | NULL    |       |
| SCOUTMASTER_NAME    | varchar(255)  | YES  |     | NULL    |       |
| SCOUTMASTER_EMAIL   | varchar(255)  | YES  |     | NULL    |       |
| COMMITTEE_NAME      | varchar(255)  | YES  |     | NULL    |       |
| COMMITTEE_EMAIL     | varchar(255)  | YES  |     | NULL    |       |
| PRIMARY_ELENGOMAT   | int(11)       | YES  |     | NULL    |       |
| SECONDARY_ELENGOMAT | int(255)      | YES  |     | NULL    |       |
| DISTRICT            | varchar(255)  | YES  |     | NULL    |       |
| ELECTION_DATE       | date          | YES  |     | NULL    |       |
| MEMBERS             | int(11)       | YES  |     | NULL    |       |
+---------------------+---------------+------+-----+---------+-------+

相关的PHP：

$query = "LOAD DATA LOCAL INFILE '$uploadedFile' 
          INTO TABLE TROOPS 
          FIELDS TERMINATED BY ',' 
          OPTIONALLY ENCLOSED BY '\"' 
          LINES TERMINATED BY '\r\n' 
          IGNORE 1 LINES  
          (NUMBER,ADDRESS,COMMENT,SCOUTMASTER_NAME,
           SCOUTMASTER_EMAIL,COMMITTEE_NAME,COMMITTEE_EMAIL,DISTRICT) ";

$result = $db->query($query);

SELECT命令的输出（注意：这正是控制台输出，带有奇怪的空格）：

+--------+--------------+---------+------------------+-------------------+----------------+-----------------+-------------------+---------------------+-----------------+---------------+---------+
| NUMBER | ADDRESS      | COMMENT | SCOUTMASTER_NAME | SCOUTMASTER_EMAIL | COMMITTEE_NAME | COMMITTEE_EMAIL | PRIMARY_ELENGOMAT | SECONDARY_ELENGOMAT | DISTRICT        | ELECTION_DATE | MEMBERS |
+--------+--------------+---------+------------------+-------------------+----------------+-----------------+-------------------+---------------------+-----------------+---------------+---------+
|      0 | 404 test st. | so cool | bob jones        | bob@jones.com     | tim hanson     | tim@hanson.net  |              NULL |                NULL | western trails  | NULL          |    NULL |
 | NULL          |    NULL | cool | bob jones        | bob@jones.com     | tim hanson     | tim@hanson.net  |              NULL |                NULL | western trails
 | NULL          |    NULL | cool | bob jones        | bob@jones.com     | tim hanson     | tim@hanson.net  |              NULL |                NULL | western trails
 | NULL          |    NULL | cool | bob jones        | bob@jones.com     | tim hanson     | tim@hanson.net  |              NULL |                NULL | western trails
|      7 | 404 test st. | so cool | bob jones        | bob@jones.com     | tim hanson     | tim@hanson.net  |              NULL |                NULL | western trails  | NULL          |    NULL |
+--------+--------------+---------+------------------+-------------------+----------------+-----------------+-------------------+---------------------+-----------------+---------------+---------+

错误和警告表都是空的。

我的问题是，“为了正确导入这些数据，我需要调整哪些内容？”

对我来说很明显，这里发生了一些奇怪的事情，尤其是不可空的主键'number'是如何为空，以及测试字符串'如此酷'如何在三个输入的中间切断。我猜测它有换行符的东西，我为LINES TERMINATED BY参数尝试了\ n，\ r，\ r \ n和\ n \ r。

MySQL LOAD DATA INFILE字段不匹配
