Display Current Connection Info in MySQL

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 −
