Filtering a hierarchy-related query
-
I've got a table with LOTS of data. It's a tree-structure (using hierarcyId datatype) and I want a query to get all of them UNLESS they have a parent that's flagged as "Inactive" in the database, then I want to skip everything that's inactive and below. I hope you get it.
If possible I want to avoid loops/cursors/CTE's etc because there are lots of data and the stuff I've tried so far ended up as very slow with these amounts of data (~150,000 rows).
I've googled myself nuts but haven't found anything useful yet.
