LoadDataInfile

When trying to get data into MySQL using LOAD DATA INFILE, you may see an error a little like this:

Error Code: 1045 Access denied for user 'myusername'@'%' (using password: YES)

There are two things you need to do to make this work:

Use the command-line flag to enable loading client data¶

The newer versions of MySQL client block load data by default. You need to pass it in as a command line switch. If you open up a Bash console you can connect to the database manually like so:

mysql -h myusername.mysql.pythonanywhere-services.com -u myusername 'myusername$default' -p --local-infile=1

"--local-infile=1" enables the load data command. You will be prompted for your password.

Use LOCAL in the MySQL command¶

The MySQL command LOAD DATA INFILE "foo.csv" tries to load the contents of the file foo.csv on the computer where the database is running. On PythonAnywhere, the MySQL server is on a different computer to the one where your code runs, so your files aren't available. Instead, you need to tell the database to load the file from the computer where the MySQL client is running, by adding the extra keyword LOCAL:

LOAD DATA LOCAL INFILE "foo.csv"
