Error Code: 2013. Lost connection to MySQL server during query 30.002 sec
There are a lot of issues with the same topic as mine but my content and issue seems to be different. In my workbench, i run the code
`select(msgid) from `table`.log where
id = 'example' and status = 'active' and month(created_at) = 12
and year(created_at) = 2018 limit 0,10;`
The above code works fine but when i run the code b
`select(msgid), count(msgid) from `table`.log where
id = 'example' and status = 'active' and month(created_at) = 12
and year(created_at) = 2018 limit 0,10;`
i get the error

Why is your query so slow? You might want to focus on making it faster instead.

You should try to increase DBMS connection read time out .
Go to Workbench Edit → Preferences → SQL Editor → DBMS connections read time out : increase this to 6000
