That is because the "Open" method is located inside unit "db" which 
isn't in the same folder as "sqldb" and thus has (by default) no debug 
information available. You could either add the 
"%fpcdir%/packages/fcl-db/src/base" directory to your project as well 
(like you did with the "sqldb" path) or you need to compile the FCL with 
debug information (I'd need to look it up, so it might be simpler to use 
the first version).
Then you should be able to step into the "query.Open" method.

Another possibility would be to place a breakpoint in one of the 
"TSQLQuery" methods (inside "sqldb"), but here you'd need to know the 
rough layout of the code flow FPC's database system uses.
