I was interested to read your post because we are considering building a solution that sounds similar to yours.
I have a system developed using sql 2005. It allows users to develop custom reports by selecting tables , then columns from the tables and I build the SQL statement from thier choices , then execute it
How have you ensured that the users select tables that have the correct FK relationships and do not pick tables that cannot be directly joined?
It maybe that SSRS is a better solution for us...but we have no experience with this...yet
