Well there's no undo

So
Yesterday i was working hard.. not hardly working as i was all week...
And suddenly somebody told me to check the announcements section in the system that i developed at work... i read that i had to delete two records from the database... well.. here's story.

I checked and see that evidently those two records should be deleted... so... i wrote a query in order to delete the status from a single job. Those records were made last year.. or at least they had last year dates.. so i should've written a query to delete those records... instead.. i wrote one that deleted 14994 records... actually.. every record from last year.. was deleted.. in just seconds!!!!..

Now that's a problem.. i thought... so.. ill keep my mouth shut and try to restore that info before anyone notices it. But i couldn't... i mean.. someone noticed it... and i had to say that there was a server error... actually it was programmer's error.. but i wouldn't admit such a thing.. so... i went to my last backup... that one had all those records deleted.. i just need to pass them from my laptop to company's server.
i tried to look for an undo query or something that would be easy to do.. but aftes a couple of hours i didn't find anything... so i made a little script that would restore all data.

after making a couple of tests on my laptop... i was ready to make the restore script run in the company's server. I was succesfull... 14992 records were inserted back to the status table in the database... but.. still 2 records were missing... i hope those are not as important as they could...

Anyways.. that time.. i spend trying to make things were back to normal... i couldn't spend it on upgrades as i would like... so now i have to do that work on monday..and the system upgrade would be once again.. a little delayed.

There's a new version for the dbms... but i'mnot sure if i should install it, since.. my laptop stoped working the same way as the server... and i have the new version in my laptop but server has an older version... ough.. desitions... i hope it's just a little bug.
