mysql - Converting varchar to date displays 0000-00-00 -

-

i trying convert column date format. in varchar , displays as: 12/06/2013

i run following query;

update dispatch    set dispatchdate = date_format(str_to_date(dispatchdate, '%d/%m/%y'), '%d-%m-%y');  alter table dispatch       change dispatchdate dispatchdate date;

however after running query, displays data as: 0000-00-00

i trying change display dd-mm-yyyy not yyyy-mm-dd

0000-00-00 mysql's special way of displaying "zero" or "dummy" date.

like many of mysql's oddities, learn live , suggest you:

update dispatch set dispatchdate = null dispatchdate = '0000-00-00'

or set whatever value works best you.

Does Firefox offer AppleScript support to get URL of windows? -

-
i trying write applescript that, among other things, gets url of every open webpage in firefox. in safari (and chrome), done simply: tell application "safari" return url of every tab in every window however, seems me firefox offers no real applescript support, such getting url of tab or window. when google terms "firefox" , "applescript" together, firefox bug requests asking applescript support restored, last updated in 2010 or 2011 (like this , this ). am right in thinking, then, firefox no longer offers proper applescript support? realize there semi-workarounds, such simulating key-commands in applescript, aren't practical purposes. to see of applescript commands firefox responds to, launch applescript editor, select menu file > open dictionary... , , choose firefox application. you'll find you're expecting: firefox doesn't offer useful applescript commands.
