MySQL in a Nutshell

Name

CURRENT_USER( )

Synopsis

CURRENT_USER( )

This function returns the username and the hostname that were given by the user for the current MySQL connection. There are no arguments for the function. This function may not always return the same results as USER( ).

SELECT CURRENT_USER( ), USER( );
+----------------+------------------+
| CURRENT_USER( ) | USER( )            |
+----------------+------------------+
| ''@localhost   | russel@localhost |
+----------------+------------------+

In this example, the user logged in to the mysql client with the username russel (missing one l in the name), but because there isn’t an account for that user, the client logged in with the anonymous (i.e., " ) account.
