python中的Mysql命令产生：SyntaxError：扫描字符串文字时的EOL

Question

我收到此错误：

SyntaxError: EOL while scanning string literal

在尝试将超过 2000 万行的 CSV 文件推送到 MySQL 服务器时，使用以下 python 代码：

cur = connection.cursor()

query = "LOAD DATA LOCAL INFILE 'path to csv file' INTO TABLE table.name FIELDS OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\r\n';"

cur.execute( query )

connection.commit()

当您用双引号将字符串文字用双引号括起来时，您应该使用反斜杠转义双引号：

query = "LOAD DATA LOCAL INFILE 'path to csv file' INTO TABLE table.name FIELDS OPTIONALLY ENCLOSED BY '\"' LINES TERMINATED BY '\r\n';"

或用三引号将字符串文字括起来：

query = '''LOAD DATA LOCAL INFILE 'path to csv file' INTO TABLE table.name FIELDS OPTIONALLY ENCLOSED BY '"' LINES TERMINATED BY '\r\n';'''
