using google I found alot of stuff regarding sp_prepare and it all looked good (sp_prepare indicates that statements are being reused = better performance)
Since I was doing this anyway out of personal interest im going to paste the links here (but try to use google ;)
Search for sp_prepare on each of these pages:
http://www.dbforumz.com/JDBC%20Driver-P ... 54125.html
http://jtds.sourceforge.net/faq.html
http://groups.google.com/group/microsof ... 13a18f3f5b
so apparently the sp_prepare has a preceding number which can be linked to a sp_execute ...but it seems to require having a full trace....
