Having finally waded through the various confusing messages in the forums giving advice on getting into MySQL, I've managed to create a user and look into the existing databases on my 5.6 test server. One of them is called 'test' and appears to be completely empty. Is this, as its name suggests, a place to play which won't mess up the other database structures in MySQl that the system depends on?
In addition to that question, I thought it might be useful for others wanting to look into using the database system, if I posted a version of the user creation command that will actually work, since not one of the commands given in the messages I was able to find did - either because they were confusing and did not tell me what I should actually do, or because they were just plain wrong. This includes the command suggested in Dan Brown's howto.
The MySQL user name does not have to be one of the names registered as a user in the SME access tables and the password used to access MySQL can be anything you like. Use your normal user name and password by all means.
User to be given access simpleton
Password dummy
To make simpleton a full privileges user who can access all the databases on the SME server, you need to go to the command line of your server and log in as root.
Then issue the following command...
mysql
...and hit enter.
At this point the prompt will change to...
mysql>
Now issue the following command
grant all privileges on *.* to simpleton identified by 'dummy';
Note the single quotation marks round the password and the semi-colon at the end of the line. Hit enter and the mysql> prompt will return.
Now type \q and hit enter again and you're out of the MySQL command console with your new user created.
When you enter your MySQL manager program on your Windows workstation you have to log onto the server and to do this you need to know one more bit of info.
The port used by MySQL is 3306.
Many of the manager programs supply this port number automatically, but some don't.
Hope this helps anyone who is as confused as I was.
