Why do you need it?
No, it is not usual or best practice. In fact this is to tell the dbms : ok, let some tables fail and break, I don’t need them, I need the rest.
This just means your DB is broken and should be restored from the latest dump
We did the same, for few hours MySQL ran fine and suddenly it when down with stack trace
This is the schema
This is the question
This is my query
What is the message in trace?
It’s wrong…
This will not even compile.
You can’t have same field under an aggregate function and NOT under it.
You either aggregate a field or have it in the group by
You can’t have same field under an aggregate function and NOT under it.

I’m not getting any error, the query is working, but the output is wrong

How can I do it?
It was logically wrong, not for your task.
And semantically wrong, but MySQL has a special ANSI compatibility flag , something like “ANSI confirming group by”, which you or your admins, apparently, turned off . That is why you don’t have errors
Okay

Install MySQL In Ubuntu 20.04
In this article, let’s see how we can install MySQL in Ubuntu 20.04 and manage it.
I ran into this error ‘incorrect key file for table tablename try to repair it’ and I realised its an issue with temp. My tmpdir is 2G and ibtmp1 is set to max 7G and table size is 5G to which I am trying add this index. Not sure if increasing the tmpdir will fix this..

buffer cache is what I understand, what do you mean by this “free memory” ?
Can check this output of free command
This is not related to MySQL at all
How the relationship between free and buffer/cache columns shown by FREE util can help this ?

“item_name” varchar(64) COLLATE utf8_unicode_ci NOT NULL,
‘on line 1
