| Hello, In my limited experience I have used a cte to write simple hierarchical result sets but this one is a bit more complicated for me. My child data records have a primary parent record, a secondary and tertiary (no more than that). This dataset will be bound to a tree for user interaction. So as mentioned in the past I had one parent and one child but this time I need to "repeat" the recursion for each child record to be recorded under each potential parent. Data Child records: FoodNameID | FoodName | FoodShortName | FoodGroupID | FoodGroupID2 | FoodGroupID3 56743 | Alumelle | Omelette | 1001 | 1007 | 1009 Data Parent Records: FoodGroupID | FoodGroupName | FoodGroupDesc 1001 | Breakfast | Big Meal 1007 | High Protein | dasfsdsdf 1009 | Eggerific | qerrewqer One thought I did have was to have a one to many relational table such as FoodName_FoodGroup with said structure: FoodNameId | FoodGroupId 56743 | 1001 56743 | 1007 56743 | 1009 If using this "join" table then the query would be pretty straight forward. Ultimately I would like to learn / use the industry best practice which is somewhat subjective but sometimes there are real obvious ones like join table vs rbar cursors. Thank You JB |
