pymysql 读取 \\n 个字符。 如何停止在 .sql 文件中运行 \\n 个字符？

Question

Error:

pymysql.err.ProgrammingError: (1064, "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 'CREATE 
PROCEDURE

) tr

I've tried changing the encoding to UTF-8 to no avail. I've also set the project settins.json "files.encoding": "utf8" in vscode; didn't work. How do I get rid of the "\\n" characters being read?

Answer 1

\\n is not the villain. Based on the error message, it is either the CREATE token or whatever came immediately before it. I expect it to be a syntax error in the DELIMITER statement. A common cause:

DELIMITER//   -- bad; need space after "DELIMITER" and the delimiter

Check the docs on pymysql -- perhaps DELIMITER is not used, and it is something else.
