I’ve been editing a task description in our worklog:
WL#946 TIME/TIMESTAMP/DATETIME with fractional seconds.

This has been around for a long time, and will be around for a long time. But I did think it’s at least time that we should let people know that we think about it. The specific impetus today was a fairly thorough survey of the feature request’s history in a MySQL DBA’s blog posting Once upon a timestamp(milliseconds)….

In my 2008-05-04 blog posting about the roadmap, I included WL#946 in a list with the heading “Let’s not forget that these will fit in somewhere in the 6.x / 7.x period”. There’s a lot to do — I know that’s not clear from reading a typical bugs.mysql.com feature request, but I hope it’s clear from clicking and reading “High Level Architecture” in WL#946.

I’ve been editing a task description in our worklog:
WL#706 Add EXPLAIN support for other statements (UPDATE/DELETE).

Currently MySQL supports EXPLAIN SELECT but there have been requests for EXPLAIN UPDATE, EXPLAIN DELETE, and so on. In fact it’s my impression that the proposition in WL#706 (transform the statement to a SELECT and then say EXPLAIN SELECT) is not what people want. But that’s okay, while a worklog is an early stage we allow simple ’solutions’ that might disappear later.
