You cannot check against the query string in a rewrite rule. You need rewrite conditions for that:
RewriteCond %{QUERY_STRING} date=([^&]+)&p=(.+)
RewriteRule ^archive/? /archive/%1/%2?
Demo here: http://htaccess.mwl.be?share=81e85c09-d505-5206-ab14-6c5059107808
If you want to actually redirect just add [R=301,L] to the end of the RewriteRule.
However, looking at the above I suspect you have your script sitting listening at /archive/index.php?data=foo&p=bar but want URLs to be like /archive/date/p, ie pretty.
This is actually a very common misconception about how htaccess URL rewrites work when you first get into them.
RewriteRules will mask or redirect URLs for you but they cannot change the underlying location a script is located at and thus the address used to pass it information.
In other words - you can mask /archive/index.php?data=foo&p=bar as /archive/date/p so that requests made to /archive/date/p resolve to /archive/index.php?data=foo&p=bar, but you cannot make it so that if you enter /archive/index.php?data=foo&p=bar as URL you have the URL change to /archive/date/p while still serving content from /archive/date/p. It has to be either or.
If this all sounds about right my advice would be as follows:
First, put your code into a different file, say /archive/script.php.
Next add the following to your htaccess:
RewriteCond %{QUERY_STRING} date=([^&]+)&p=(.+)
RewriteRule ^archive/? /archive/%1/%2? [R=301,L]
RewriteRule ^archive/([^/]+)/([^/]+) /archive/script.php?date=$1&p=$2
Note that the first two lines are the same as before, but now there is a new line that looks for the masked URL format of /archive/date/p and sends it off to the actual script, which is handled by the new RewriteRule.
The behaviour of the new rule is demoed here: http://htaccess.mwl.be?share=06751667-f16f-5c13-91eb-dd5cffdc6db3
Hope this makes sense / helps.
