问题描述

我有一个表组
contains

GroupID   GroupName ChildId
1           G1        0(0-Means Root Group)
2           G2        0
3           G3        0
4           G4        0
5           G5        1(The GroupId of First Row)
6           G6        5(The GroupId of Fifth Row)
7           G7        2(The GroupId of 2nd Row)
8           G8        7(The GroupId of 7th Row)
9           G9        8(The GroupId of 8th Row)

Now I Want The Group Name Of Root Group
Through Sql query only I want to get
the Name Of the main Group Through its child Id.
For Ex. If I select 9(Group Id) It Is Linked With Main Id-2
9->8->7-2-0(Means Group Name-G2)-Where we will get zero it is over

Thank You
