That probably means it is broken in many other tools too. I'll take a look. Thanks Dave! That probably means it is broken in many other tools too. I’ll take a look.

Partitions and other options are included, but not output by default if they are NULL. The textual tree-view output actually doesn't show all the information in the tree built from EXPLAIN; I wanted to keep it as brief as possible. But if your EXPLAIN output includes partitions, you should see the results in the tree. This makes me realize, there's no way with the --connect option to ask MySQL Visual Explain to EXPLAIN the command as EXPLAIN PARTITIONS! I will add an option to do that. This of course only affects what data it gets from the server, not how the tree is built; if you give it text as input instead of a command, it'll show all the information it's given. [EDIT] I see I'm too smart for myself. It runs EXPLAIN /*!50115 PARTITIONS*/ SELECT so it should work fine. I completely forgot that I did that. Thanks Peter.

You may also look at explain options to get more info such as partitions used etc. Great Baron,
