I have multiple text console session open and log in as different users into different consoles. I forget after while which consoles belong to which user, it would be nice to not have to quit and log back in.

How do I see which user I am logged in as?

Is there a way to change which user I logged in as with out logging out?

Actually, you need to use two functions


USER() reports how you attempted to authenticate in MySQL

CURRENT_USER() reports how you were allowed to authenticate in MySQL

Sometimes, they are different

eg. if you login to mysql via mysql -ulalala where lalala user doesn't exist, you will be allowed to login as 'anonymous' mysql user, namely ''@'localhost'. In this case returns of functions would be USER()= lalala@localhost and CURRENT_USER() = @localhost – Dimitry K Jan 27 '15 at 14:23
@DimitryK When that happens, you can run SHOW GRANTS; to see what permissions you have. Even if you see nothing except USAGE, you still need to be aware that certain test databases are 100% accessible to an anonymous user. See my post MySQL : Why are there “test” entries in mysql.db? ( – RolandoMySQLDBA Jan 27 '15 at 14:38
+1 for SHOW GRANTS, strange that I haven't stumbled upon it though reading numerous Mysql Tutorials. – Dimitry K Jan 27 '15 at 15:18


select user();


I pinched it from the 3rd google result for 'mysql whoami':

I found this user() function

select user(); Will show you which user is logged in.

Does that link still work for you? I decided to link to google's cache because of the mysql -> oracle breakage. – PriceChild Apr 5 '11 at 8:00
It does work, it has an other interesting function as well select database(); will show you your currently selected database. – nelaar Apr 5 '11 at 8:07
That's really annoying, I wonder why it doesn't work for me. Thanks. – PriceChild Apr 5 '11 at 8:08

Nope, sends me to… – PriceChild Apr 5 '11 at 8:30

You can use 'status':

MariaDB [my_database]> status

Current user: root@localhost
