Hi  ,




I have a table like this :



table_a (id1,id2) : ( 1,2)


                          (1,3)

                          (5,7)

                          (7,8)

                          (3,1)





I need to find all matched values . The result will be as follows:



cluster1:  1,2,3


cluster2:   5,7,8



How can i do this? ( either by sql or etc)



Kind Regards,


tolga
