I would say dynamic SQL is your best option. The task that you are looking to accomplish seems a bit bewildering and there are little alarms going off in my mind that make me question whether you are making the whole insert process more complicated than it needs to be. However, I know there are some wild requirements out there and I'll assume that what you are trying to do is necessary. Since you are already studying whether dynamic SQL is the best option, I don't think there is anymore i can add.

Yes, mapped statement. I want to build a giant subquery that depends on how many groups I have. So if I have one group I get the list of rules for it (could be 27 of them) each of these are in an object which I then thought I'd put them in a vector to pass to the mapped statement.But then I was unsure of how to get them out since each object has the same fields in it but different data (meaning different set of rules). So I need to build the subquery's where clause with these and going back to the beginning here if there is more then one group I could have multiple groups with multiple rules and each group if it exists needs to be either a UNION or INTERSECT.
