Connector problem

Need help Database
1

Hello, I want to connect mysql DB to my app by connector plugin in Bubble.is

I bought hosting site(hostgator) to host my schema but I couldn’t make string to connect.

ex)
connection string
mysql://username:password

does username, password means hosting site’s username and password or just of mysql?

also

@my-db-instance.endpoint.us-east-1

I can not understand this sentence, May I just copy them? or Do I have to change something?

and

rds.amazonaws.com:PORT

I can understand Port, but ‘rds.amazonaws.com’ Does it mean hosting site?

Really thanks to read my problem,

I take it you are referring to the default example provided by the SQL Database Connector:
mysql://username:password@my-db-instance.endpoint.us-east-1.rds.amazonaws.com:PORT/db_name

Breaking it down:
mysql://
username:password for the database user
@
my-db-instance.endpoint.us-east-1.rds.amazonaws.com replace with hostname or hostaddress of your database, which might be an IP address. If it is “localhost” then the database is likely only for use by the site, so can’t be directly accessed by the SQL connector plugin.
/
db_name the database schema name

There is an explanation here: http://support.hostgator.com/articles/sql-connection-strings

Hostgator also have a support chat, it’d be worth asking them about the connection string for external access.
