This sounds like a very simple question, but for some reason I couldn't find an answer for it anywhere.
I checked mysql server setting and it looks like there is no such a variable - for commands, it is probably up to a client:
show variables where variable_name like '%timeout%'
I'm trying to figure out when active record mysql adapter would timeout a mysql query/command if it ever would.
There are related questions, but not rails-specific: mysql Command timeout error
Thank you.

I am trying to connect to a local mysql server (5.6.37) running on linux (gentoo) using mysql workbench (6.3.9). I get an "Unsupported operation provided to mysql_options()" error message and cannot connect. I am aware of the very similar question posted here, the bug report about the issue and the supposed fix.
However, none of the suggested solutions seem to apply in my case. The system variable old_passwords is not enabled (ie is set to 0) and all users are using the mysql_native_password plugin explicitly, as described in the fix. I am at a loss on what to try next. Can someone help me figure out what I've missed?
Thanks
I'm hoping this is a simple question. I recently installed MySQL Workbench, and thought everything was going fine, until I noticed the output of messages at the bottom. They're in a foreign language. See attached screenshot. I tried the same queries in phpMyAdmin and get similar results.
Server connection collation: utf8mb4_general_ci (I tried to change to utf8_general_ci but it won't let me)
Any help is greatly appreciated.
Try changing your my.ini file to the following:
lc-messages=en_US
or run the command prompt and in the mysql prompt do:
SET lc_messages = 'en_US';
Check the following reference
Once again I need your help:) . I am new to mysql and today when I decided to do some work and start the MySQL server, I get the following warning
"[Warning] TIMESTAMP with implicit DEFAULT value is deprecated".
I know I should change something somewhere but I don't know where... I'm trying to start MySQL server with executing mysqld file in bin directory. I would be very grateful if someone manage to explain me why MySQL server does not want to start and what can I do... Thank you in advance.
You'll want to set explicit_defaults_for_timestamp
Append --explicit_defaults_for_timestamp=# onto your command line.
Setting it in your option file my.ini / my.cnf / etc - Option-File Format.
setting it as a system variable.
That is caused when upgrading from MySQL 5.5 to MySQL 5.6. It looks like you have more than one version of mysql on your computer. Read here for more.
if u r using mysql 5.6 and getting
"[Warning] TIMESTAMP with implicit DEFAULT value is deprecated".
when u use mysqld in commandline, just don't worry, don't panic...
What u have to do is go in start menu-> programs-> mysql-> mysql server 5.6-> mysql commanline client.(Windows)
u will be asked to enter password, enter ur root password.
then u will see
mysql>
start creating database directly
Try it its simple, but will solve ur problem... it solved mine!
Running the following command in a remote login attempt in a MySQL shell.
show variables;
The query only shows the last 50 or so variables out of 233. I would like the result to be scrollable so that I can review all of the variables. Something like a redirect to 'less.'
As it is, I am stumped.
You could try using the following command to set a "less"-type of behavior in the MySQL command line:
pager less
Also, this behavior can be turned off by using this command:
pager
(Note: This might not work on every flavor of MySQL... for more information, check the docs.)
My web threw the error "MySQL server has gone away". I google it, find a method that use mysql_ping function, but I use extension mysqli, not mysql.
How can I fix this problem?
There is a mysqli_ping method for this, as well:
http://us3.php.net/manual/en/mysqli.ping.php
However, in my experience, ping was not needed. All I had to do was add mysqli.reconnect = "1" to my php.ini.
Ref. check if mysql connection is valid
You may get this error when your query is crashing MySQL server check MySQL error log file for that.
If values for wait_timeout & interactive_timeout MySQL server variables is set to very low in MySQL configuration file. Try increasing values for them and then restart MySQL server.
This is basically a time between two queries and after opening new connection if you don't execute next query before this timeout then your connection will be automatically closed by the MySQL server and you will get this error.
Stop and start mysql server to fix this problem.
