Just encountered an interesting issue.
I use DNS names instead of IPs in mysql grants. Yes, I'm aware of the
performance impact, that's not an issue.
I just found out through failing logins that a server was still connecting to
an old DNS server, and properly updated the resolv.conf.

Consider also the DNS TTL.
If you flush hosts in MySQL it'll ask again the OS to resolve a name , but
if that is still in the DNS cache it could return that 'old' value instead
of querying the newly updated NS.
I'm not sure thou, may be test by restarting the name server cache

I doubt that mysql calls anything other than gethostbyname() or
getaddrinfo(), so your behaviour is probably dependant on whatever OS
you are running and how often its local resolver re-checks resolv.conf.
Usually that's

Nestor, I've already asked you check value of sql_select_limit variable:
SELECT @@session.sql_select_limit;
Is SELECT * FROM course_eng exact query that you use?
Has anyone run into this simmilar problem?
Victoria,
The seleect statements that I wrote is what I use.
And if there was a limit should the limit be used in both o f my select?
Database changed
mysql SELECT @@session.sql_select_limit;
