MySQL provides many functions that give the current connection information. For instance, to know about the current user, use the user() function.
Syntax
mysql> SELECT CURRENT_USER();
Here is the output that displays the name of the current user.
+----------------+ | CURRENT_USER() | +----------------+ | root@% | +----------------+ 1 row in set (0.00 sec)
In the above, % tells us about localhost.
To check the current connection id, use the following method −
mysql> SELECT CONNECTION_ID();
The following is the output that shows the current connection id.
+-----------------+ | CONNECTION_ID() | +-----------------+ | 8 | +-----------------+ 1 row in set (0.02 sec)
The following is the syntax to check all the current information with a single command.
mysql> status;
The following is the output −
