*** SQL Server? SELECT Id, COALESCE(Top , Pr.Top ,0) AS Top, COALESCE(Left , Pr.Left ,0) AS Left, COALESCE(Width , Pr.Width ,0) AS Width, COALESCE(Height, Pr.Height,0) AS Width, COALESCE(Color , Pr.Color ,0) AS Color FROM MyTable LEFT JOIN MyTable Pr ON MyTable.Parent = Pr.Id>Hi,

This means ID 3 would be: > 10 10 200 100 Red >* ID 4 would be: > 20 20 100 100 Green >* etc >>I had this coded in VFP using recursion to 'walk' back up the tree to the root record and then build the final spec by unwinding back down. Any suggestion on how to implement this using ADO/SQLServer (with as much as possible in SQL since this data may also be accessed by other front ends)?
