Question

I’m using heroku to deploy my app. So far, I’ve been using a development version of my app, and seeding some data into it. I also have a production version set up on heroku.
Both apps are using a mysql database hosted with ClearDB to store the data.
I simply want to move the data from the development version to the production version.
Using MySql Workbench, I exported the dev data to a file and tried to import it to the prod db, but I got an access denied error because it tried to log into the dev db with production credentials.
The databases have identical table/row/column structure. How can I take the data from one and insert it into the other?

You can use a combination of the ‘mysql’ and ‘mysqldump’ command line
clients to “copy” one database’s contents to the other. Here’s an example of
how to do this:

mysqldump --single-transaction -u (old_database_username) -p -h (old_database_host) (database_name) | mysql -h (new_host) -u (new_user) -p -D (new_database)

with line breaks:

mysqldump --single-transaction -u (old_database_username) 
-p -h (old_database_host) (database_name) | mysql -h (new_host)
-u (new_user) -p -D (new_database)
