A SQL Question...

Bear with me... I'm kinda new here.

I am trying to query table1, selecting records that do NOT have a relation in a subset from table3 that is related to
table2.


Example:

table1(Trick table)
 1_id,trickName,trickDescription

table2(Magician table)
 2_id,lastName,firstName

table3(Trick-Magician-Knows table)
 2_id,1_id

if I choose some magician I want a list of tricks he/she DOES-NOT know.

thanks for any insight !
