问题 I am trying to connection to a MySQL server on Host X through machine Y over SSH. The same setup (but older version of MySQL workbench) works on my another box (CentOS 6.3). However, the same setup doesn't work on my CentOS 6.5. I tried to use the SSH key for authentication between my box and machine Y over SSH, and it works when I ssh from my box to machine Y.

问题 I apologise.. I know this question has been asked many times before, but I've tried lots of suggestions, and simply can't find a solution.

问题 I'm posting this as a Q&A to document a workaround for a problem that seems to come up frequently—how to put MySQL Workbench files under version control—but for which I have been unable to find any solutions. Feedback is welcome! How can I tell Mercurial to diff the contents of a zipped archive and ignore some of the changes to those contents? Specifically, how can I use hg to diff the contents of a MySQL Workbench ( .mwb ) file, ignoring the many unimportant changes that MySQL Workbench

问题 I have a query that does multiple joins on several tables and uses a covering index. It seems to run a lot faster when executed directly from the mysql cli instead of from mysql workbench. mysql > some query ... 250 rows in set (0.05 sec) from mysql workbench it takes about ~0.200 sec duration / 0.100 sec fetch Is there a reason beyond latency, authentication and transfer of data why it would be orders of magnitude faster on the console? Does a three-way tcp handshake occur each time a query
