I can make query to get the Master -Chile records. But how to display them in hierarchial fashion. Any e开发者_如何学JAVAxample will help
I am using SQL Server 2005
There are more elgeant ways, but this quick modification will work:
;With bottomupParentChild AS
(
SELECT EmpId AS parents, ReportsTo,CAST(EmpName AS VARCHAR(1000)) AS [Path], 0 AS [Level], EmpName
FROM @Employees
WHERE EmpId = @childNode
UNION ALL
SELECT i.EmpId AS parents, i.ReportsTo, CAST(gp.[Path] + '/' + i.EmpName AS VARCHAR(1000)) AS [Path],
gp.[Level]+1 AS [Level],i.EmpName
FROM @Employees i
JOIN bottomupParentChild gp ON i.EmpId = gp.ReportsTo
)
, cteRows (TotalRows)
as (select count(*) - 1 from bottomupParentChild)
SELECT ABS(Level - TotalRows), REPLICATE(' ', ABS(Level - TotalRows)) + EmpName as [Hierarchy]
FROM bottomupParentChild
cross join cteRows
ORDER BY [Path] desc;
I added a second cte that gets the count of rows from the first cte, and use it to "flip" the hierarchy.
