[rules-users] questions

Is anyone making database calls in rules from condition side .. if yes ... can anyone send me the lines of code which are working .. if you declare something global it cant be accessed in LHS .. is this right ? even though the rule wont throw any error but it wont execute the line either .. so something like a dao which i will be using to make various calls to database (in LHS) .. if i decalre it global i cant use it .. i should not assert it as a fact as it is not a fact .. what's the right way of doing it ? Can somebody please help ..
