Retrieve client ip address in mysql

Question

I'm trying to get with a simple SQL statement the IP address of the client. I do not want to use PHP or other techniques. Only pure SQL. When I use

SELECT USER();

I get

[email protected]

When I use

SELECT CURRENT_USER();

I get

dbouser@%

But how do I get the plain IP? Thanks a lot in advance.

Answer 1

You will only get the IP address of the client process communicating with MySQL. Assuming this is what you want:

select host from information_schema.processlist WHERE ID=connection_id();

Will give you the host name (or IP address if name resolution is not enabled, which it is usually not) connecting to the mysql server on the current connection.

Answer 2

To get the IP address only without the port number.

select SUBSTRING_INDEX(host,':',1) as 'ip' from information_schema.processlist WHERE ID=connection_id();
