How to display current connection info in MySQL?

MySQLMySQLi Database

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 −
