[mysql] Show MySQL host via SQL Command

Show Database
Use database
show tables
Describe <table>

All good and well, but is it possible to show the current connections host. Not connection_id, but the IP Address or Name of the host.

show variables where Variable_name='hostname'; 

That could help you !!

I think you try to get the remote host of the conneting user...

You can get a String like 'myuser@localhost' from the command:

SELECT USER()

You can split this result on the '@' sign, to get the parts:

-- delivers the "remote_host" e.g. "localhost" 
SELECT SUBSTRING_INDEX(USER(), '@', -1) 

-- delivers the user-name e.g. "myuser"
SELECT SUBSTRING_INDEX(USER(), '@', 1)

if you are conneting via ip address you will get the ipadress instead of the hostname.

Maybe

mysql> show processlist;
