Hi
i have 3 master tables 1)RoleDetails(Roleid(PK),name,masterroleid(fk) ref:RoleDetails roleid)
2) PositionDetails(positionid(PK), name,MasterPositionid(FK) ref:PostionDetails postionid,Roleid(fk) ref:Roledetails roleid)
3) Userdetails(userid(pk), loginid,pwd,roleid(fk) ref:roledetails roleid,positionid(fk)ref:postionDetails positionid,fname,address)
how to Create two functions one return child nodes as per Case 1 and another one is return Parent Nodes
as per case 2
        (Manager) a -- r1 (roledetails)
           / \

      (ROL)a1 (ROL) a2 -- r2
    / | \ / | (RO)b1 b2 b3 b4 b5 b6 -- r3
Case 1:
On passing the User ID of (a) , should get the Output as User id of ( b1,b2,b3,b4,b5,b6) along with their Role ID.

On passing the User ID of (a1), should get the Output as User ID of (b1,b2,b3)along with their Role ID.

Case 2:
On passing the Role ID of (R3), should get the User ID of all the Parent roles( a1 and a2 (R2), a(R1)long with their Role id

plz someone get me out of this.. thanks in advance.
