sql - Select date which is bigger than another date on a second afinity -

-

i have 2 identical tables in 2 different dbs ( 1 local , 1 remote ). both of them have datetime ( or datetime2 or else, can still change ) column specifies when added. want records remote table local table have not been brought.

for max value local table, tried put condition where remotetable.createtime > maxlocalvalue, don't know why seems overwrite records on boundry. better way ? on second or minute level ?

since know values have been added local table, add values remote table not in local table. let local_table repersents local table , remote_table repersents remote table , rcd_1 column in both tables repersents date type.

insert local_table (col_1,.....(how evermany columns need), rcd_1) select rcd_1 remote_table  remote_table.rcd_1 <> local_table.rcd_1;

the way explained question suggest newer dates added local remote long hold true should desired results.

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.
