How to see full query from SHOW PROCESSLIST

Question

When I issue SHOW PROCESSLIST query, only the 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)

Answer 1

SHOW FULL PROCESSLIST

If you don't use FULL, "only the first 100 characters of each statement are shown in the Info field".

When using phpMyAdmin, you should also click on the "Full texts" option ("← T →" on top left corner of a results table) to see untruncated results.

Answer 2

See full query from SHOW PROCESSLIST :

SHOW FULL PROCESSLIST;

Or

 SELECT * FROM INFORMATION_SCHEMA.PROCESSLIST;

Answer 3

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 :

+-------+------+-----------------+--------+---------+------+-----------+----------------------------------------------------------+
