Ok Sorry for my xplanation
Kindly assume T1, T2, T3 - Tables
T1 |
----
P1 |
C3 |
C2 |
T2|
---
C3 |
C2 |
C1 |
R1 |
T3
---
Col1 - Col2
P1 - C3
C3 - C2
C2 - C1
C1 - R1
All those values are linked as Chain in third Table T3 in 2 cols, but the start of the Chain is P1 which leads to C3 --> C2 --> C1 --> R1.
So need to show tht P1 is the start for all those commencing values.
Now, need a query which ll display those as like below,
Col1-Col2
P1 - C3
P1 - C2
P1 - C1
P1 - R1
Kindly help me to arrive at teh query... plz
Thanks for ur Help!!
Hi
This is similar to parent child relationship and finding out all the childerns of a parent using T3 table (where the Parent and Child relationship is mentioned).
Check out the below link on Tree & hierarchical queries.
