Trouble with recursive CTE achieving expected results in SQL Server 2019
Hey everyone, I'm running into an issue that's driving me crazy. I'm having issues with a recursive Common Table Expression (CTE) in SQL Server 2019 that is supposed to return a hierarchy of employees based on their manager's ID. The CTE runs without errors, but it doesn't return all expected rows. I’m trying to get all subordinates for each manager, but I only see direct reports returned, not the deeper levels in the hierarchy. Here's what I've tried: ```sql WITH EmployeeHierarchy AS ( SELECT EmployeeID, ManagerID, EmployeeName FROM Employees WHERE ManagerID IS NULL -- Start from top-level managers UNION ALL SELECT e.EmployeeID, e.ManagerID, e.EmployeeName FROM Employees e INNER JOIN EmployeeHierarchy eh ON e.ManagerID = eh.EmployeeID ) SELECT * FROM EmployeeHierarchy; ``` I expect to see all employees under their respective managers, but the output only shows the immediate subordinates. I also tried adding a `WHERE` clause to filter based on roles, but that didn’t help. Running `SELECT COUNT(*) FROM EmployeeHierarchy` gives me fewer rows than I expect. I’ve checked the data, and there are definitely employees with multiple levels of hierarchy. Could it be related to a missing or incorrect join condition? Any insights or suggestions on how to fix this would be greatly appreciated! This is part of a larger CLI tool I'm building. How would you solve this?
