Subj:   Implementation of self Join in teradata
 
From:   Pavan_Mangavalli

Hi All,

I have a question regarding implementation of self join on a table in teradata. Say If I do a self join on a table(which has X columns) for N times with a projection on one column then what will be the initial Cartesian product of this self join. Is it X * N or 1(one column) * n.


Regards,

Pavan
