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

Question

I get this error:

SyntaxError: EOL while scanning string literal

while trying to push a CSV file of more than 20 million rows to MySQL server, using this python code:

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()

When you enclose a string literal with a double quote in double quotes, you should either escape the double quote with a back slash:

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

or enclose the string literal in triple quotes:

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