When I issue SHOW PROCESSLIST query, only first 100 characters of the running SQL query are returned in the info column.
Is it possible to change Mysql config or issue a different kind of request to see complete query (the queries I'm looking at are longer than 100 characters)
This question is related to

See full query from SHOW PROCESSLIST :
SHOW FULL PROCESSLIST;
Or
SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST;
I just read in the MySQL documentation that SHOW FULL PROCESSLIST
by default only lists the threads from your current user connection.
Quote from the MySQL SHOW FULL PROCESSLIST documentation:
If you have the PROCESS privilege, you can see all threads.
So you can enable the Process_priv
column in your mysql.user
table. Remember to execute FLUSH PRIVILEGES
afterwards :)
Show Processlist fetches the information from another table. Here is how you can pull the data and look at 'INFO' column which contains the whole query :
select * from INFORMATION_SCHEMA.PROCESSLIST where db = 'somedb';
You can add any condition or ignore based on your requirement.
The output of the query is resulted as :
+-------+------+-----------------+--------+---------+------+-----------+----------------------------------------------------------+
| ID | USER | HOST | DB | COMMAND | TIME | STATE | INFO |
+-------+------+-----------------+--------+---------+------+-----------+----------------------------------------------------------+
| 5 | ssss | localhost:41060 | somedb | Sleep | 3 | | NULL |
| 58169 | root | localhost | somedb | Query | 0 | executing | select * from sometable where tblColumnName = 'someName' |
If one want to keep getting updated processes (on the example, 2 seconds) on a shell session without having to manually interact with it use:
watch -n 2 'mysql -h 127.0.0.1 -P 3306 -u some_user -psome_pass some_database -e "show full processlist;"'
The only bad thing about the show [full] processlist
is that you can't filter the output result. On the other hand, issuing the SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST
open possibilities to remove from the output anything you don't want to see:
SELECT * from INFORMATION_SCHEMA.PROCESSLIST
WHERE DB = 'somedatabase'
AND COMMAND <> 'Sleep'
AND HOST NOT LIKE '10.164.25.133%' \G
