Download of database dump

[mitjanikolaus]

I tried downloading a database dump (version 2020.1) using the instructions at http://childes-db.stanford.edu/releases.html . However, the result that I got when writing it into a file was only this (no data was exported):

-- MySQL dump 10.13  Distrib 8.0.21, for Linux (x86_64)

-- Host: ec2-54-68-171-132.us-west-2.compute.amazonaws.com    Database: 2020.1

We will update the information shortly, but the address changed, so the server is: ec2-34-212-148-26.us-west-2.compute.amazonaws.com. You should also use the --single-transaction option. We will update all of this soon.

Thanks for the quick reply! Unfortunately it still doesn't work. I am getting: mysqldump: Error: 'Access denied; you need (at least one of) the PROCESS privilege(s) for this operation' when trying to dump tablespaces

(I'm using the username and password from the childes-db.json and using the --single-transaction option.

[sarpu]

Could you try this instead? mysqldump -v -u childesdb -p -h ec2-34-212-148-26.us-west-2.compute.amazonaws.com --single-transaction --no-tablespaces -C --quick --databases 2020.1 And the password is childes-db.json one.

What is your mysqldump version?

[mitjanikolaus]

Ah! I got it: It's because I'm using apparently because I'm using mysql 8. The solution is to use `--column-statistics=0

(https://serverfault.com/questions/912162/mysqldump-throws-unknown-table-column-statistics-in-information-schema-1109)

[sarpu]

Yes I was about to suggest that. Will close the issue after I update the website.
