MySQL Workbench: How to keep the connection alive


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?


Solution

  • 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.
