MySql 加载数据本地语法?
我有一个使用管道'|'的文本文件result.txt"分离字段.我使用了 PhpMyAdmin 并通过指定使用CSV 负载数据"并告诉它字段应该用|"分隔来成功地将它导入到我的表中.
I have a text file "result.txt" that used pipes '|' to separate out the fields. I used PhpMyAdmin and successfully imported it to my table by specifying using "CSV LOAD DATA" and telling it the fields should be separated by '|'.
PhpMyAdmin 也给出了完整的查询，所以我复制了它并粘贴到我的 php 脚本中，如下所示:
PhpMyAdmin also gave the full query for it, so I copied it and paste it into my php script, which looked like this:
mysql_query("LOAD DATA LOCAL INFILE 'C:/wamp/www/TouchStone/result.txt' INTO TABLE customer_change FIELDS TERMINATED BY '|' ESCAPED BY '\' LINES TERMINATED BY '
' ")
or die(mysql_error());
我总是会收到错误提示:
I will always receieve error saying:
您的 SQL 语法有错误；检查与您的 MySQL 服务器版本相对应的手册，以获取在第 2 行的 ''' 附近使用的正确语法
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 2
我想知道，因为我复制了 phpmyadmin 生成的完全相同的查询，我认为它肯定会在这里工作.但是为什么会出现这样的错误呢?
I was wondering, since I copied exactly the same query generated by phpmyadmin, I think it will definitely work here. But why will such error happen?
我尝试修剪查询以仅包含FIELDS TERMINATED BY"并且它起作用了.但是以这种方式填充的数据库将包含不正确的数据.所以我真的很想知道为什么原来的较长查询会失败?
I tried trimming the query to contain only "FIELDS TERMINATED BY " and it worked. But the database populated this way will contain incorrect data. So I am really wishing to learn why would the original longer query would fail?
谢谢.
推荐答案
您正在使用双引号字符串，因此
将被视为文字回车和换行人物.您还需要对它们进行双重转义:\r\n.
You're using a double-quoted string, so the
will be seen as literal carriage return and line feed characters. You'll need to double-escape them as well: \r\n.
错误消息中的第 2 行"证明了这一点 - 如果您的查询没有实际的第二行，但由于嵌入的换行符/回车，一旦它到达 MySQL.
The "on line 2" in the error message is evidence of this - there's no actual second line if your query, but because of the embedded newline/carriage return, there is once it gets to MySQL.
