Robots.txt syntax - remove pages via Google webmaster tools

I recently changed some pages on my site and submitted a request to remove the old URLs

My pages changed from

details.php?categoryid=23

to details.php?catid = 23

23 is just an example. I have a few other catids besides 23

After reading the Google requirements for removing a URL it looks like I need to place the URLs I wanted deleted in the robots.txt file.

Now my question. Would it be correct to insert something like

Disallow: details.php?categoryid

in the robots.txt file in order to make sure these pages are not recrawled? And so I can get them removed via Google's webmaster removal tools?

The pages with ?categoryid=number still loads but the data is not correct, therefore I would like to have them removed from Google.

I hope I asked my question clearly.
