I have the same problem and it looks like this is due to Shell MySQL. Not a classic mysql.exe command line tool. I am trying to connect to a MySQL Azure database from the MySQL shell as follows:
mysql-sql> \sql
mysql-sql> \connect -c myuser@myserver.mysql.database.azure.com
Creating a Classic Session to 'myuser@myserver.mysql.database.azure.com'
Enter password: *********
ERROR: 2001 (28000): The connection string may not be right. Please visit portal for references.
mysql-sql>
Azure ( ) "_ @servername", MySQL.
- Azure MySQL db MySQL?
, mysql.exe, :
mysql.exe -u myuser@myserver -h myserver.mysql.database.azure.com -p
, , MySQL at (@) .
