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          


        

Answer 1

@mvf - instead of reverse you could do:

SELECT SUBSTRING_INDEX(USER(), '@', -1) AS ip;

Answer 2

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 3

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();

Answer 4

SELECT REVERSE(SUBSTRING_INDEX(REVERSE(USER()),'@',1)) as ip;
SELECT SUBSTRING(USER(), LOCATE('@', USER())+1) as ip;
