MySQL Workbench: How to keep the connection alive
MysqlSqlMysql WorkbenchConnection TimeoutMysql Problem Overview
Error Code: 2013. Lost connection to MySQL server during query
I am using MySQL Workbench. Also, I am running a batch of inserts, about 1000 lines total (Ex. INSERT INTO mytable SELECT * FROM mysource1; INSERT INTO mytable SELECT * FROM mysource2;...mysource3...mysource4 multiplied 1000 times) Each batch takes a considerable amount of time, some of them, more than 600 seconds.
How can I configure workbench, to continue working overnight, without stopping and without losing the connection?
Mysql Solutions
Solution 1 - Mysql
From the now unavailable internet archive:
> Go to Edit -> Preferences -> SQL Editor and set to a higher value this parameter: DBMS connection read time out (in seconds). For instance: 86400. > > Close and reopen MySQL Workbench. Kill your previously query that > probably is running and run the query again.
Solution 2 - Mysql
If you are using a "Standard TCP/IP over SSH" type of connection, under "Preferences"->"Others" there is "SSH KeepAlive" field. It took me quite a while to find it :(
Solution 3 - Mysql
In 5.2.47 (at least on mac), go the location of the preferences is: MySQLWorkbench->Preferences->SQL Editor
Then you'll see both:
DBMS connection keep-alive interval (in seconds): DBMS connection read time out (in seconds):
The latter is where you'll want to up the limit from 600 to something a bit more.

In my case after trying to set the SSH timeout on the command line and in the local server settings. @Ljubitel solution solved the issue form me.
One point to note is that in Workbench 6.2 the setting is now under advanced
Solution 5 - Mysql
I had a similar problem where CREATE FULLTEXT timed out after 30 seconds:
Setting DBMS connection read timeout interval to 0 under Edit -> Preferences -> SQL Editor fixed the issue for me:
Also, I did not have to restart mysql workbench for this to work.
Solution 6 - Mysql
If you are using a "Standard TCP/IP over SSH" type of connection, it might be the ssh server that keeps timing out, in which case, you would have to edit TCPKeepAlive related settings in /etc/ssh/sshd_config on your server.
Solution 7 - Mysql
I was getting this error 2013 and none of the above preference changes did anything to fix the problem. I restarted mysql service and the problem went away.
Solution 8 - Mysql
OK - so this issue has been driving me crazy - v 6.3.6 on Ubuntu Linux. None of the above solutions worked for me. Connecting to localhost mysql server previously always worked fine. Connecting to remote server always timed out - after about 60 seconds, sometimes after less time, sometimes more.
What finally worked for me was upgrading Workbench to 6.3.9 - no more dropped connections.
Solution 9 - Mysql
in mysql-workbech 5.7 edit->preference-> SSH -> SSH Connect timeout (for SSH DB connection)
