hi I hope somebody already solved that problem 🙂 I have a dataset memory tag which i would like to use to query but I don’t know how. As i understand system.db.query(SQLQuery) is only for external tables - is it right? Regards ---

You are in luck! Long ago, I needed this and created a module that includes it. The “SQL” is more of a pythonic pseudo-SQL, but looks an awful lot like regular SQL for most cases: [Simulation Aids](https://inductiveautomation.com/moduleshowcase/module/automation-professionals-llc-simulation-aids) Use the [view() expression function](https://www.automation-pros.com/simaids/doc/expression.view.html). Don’t let “Buy this module” discourage you – it is **free**. ---
