Hello everybody out there using PostgreSQL,
After having read the official documentation and having done
extensive web search, I'm wondering how to perform something like a
SELF LEFT OUTER JOIN in PostgreSQL, i.e. a SELF JOIN on a table
containing NULL values in one of the columns to join.
Something like this? -
select....
from my_table a
left join my_table b on (a.my_column = b.my_column)
...
Would this do it?
Ray.
