Join Sveta Smirnova Thursday, August 11 at 10 am PDT (UTC-7) for a webinar on InnoDB Troubleshooting.

InnoDB is one of the most popular database engines. This general-purpose storage engine is widely used, has been MySQL’s default engine since version 5.6, and holds MySQL system tables since 5.7. It is hard to find a MySQL installation that doesn’t have at least one InnoDB table.

Docker Images for MySQL Group Replication 5.7.14

MyQuery 3.5.6 released
+0 Vote Up -0Vote Down

I released version 3.5.6 of MyQuery, and there are quite a number of new features and fixes in there. The #1 bugfix is that the annoying access warnings that poped up from Windows when saving to the registry are gone, as I have now moved the registry to a more Windows 10 acceptable place. Among the new features are:

  • JSON format output when saving results.
  • More flexible CSV format output with many new options.
  • Ability to save Dyncol as JSON in CSV and JSON output.
  • Nicer formatting of numbers in status dialogs.
  • Auto refresh of status dialogs
