How Can I Prevent MySQL Workbench from Losing Connections During Long-Running Queries?

Preventing MySQL Workbench Connection Drops During Extended Queries

Long-running queries in MySQL Workbench can lead to connection timeouts, interrupting overnight batch processes. This article outlines how to maintain persistent database connections.

To prevent connection loss, modify the read timeout setting within MySQL Workbench's SQL Editor preferences. Follow these steps:

1. Access Preferences: Open MySQL Workbench and go to "Edit" > "Preferences".
2. Configure Timeout: In the "SQL Editor" section, find "DBMS connection read time out (in seconds)". Increase this value significantly, for example, to 86400 seconds (24 hours).
3. Restart for Changes: Close and restart MySQL Workbench to activate the new timeout setting.
4. End Active Queries: Stop any currently running queries that might have timed out previously.
5. Rerun Queries: Re-execute your batch queries. The increased timeout should prevent connection interruptions.

By increasing the DBMS connection read timeout, your MySQL Workbench sessions will remain connected even during lengthy query executions, ensuring uninterrupted overnight batch processing.
