It's bad idea to enable users to build and run queries...

Bad idea! Create modules that allow users to specify WHAT they need. You should create the query based on their request. Otherwise you'll have to have very carefuly managed rights so that users cannot delete, drop and otherwise destroy data or the database. And additional validation so that no one can do one of those things even if somehow they get the rights (that is, that your app cannot do that).
