How to jion 2 tables, without using any condition?
Answer Posted / manjula
it is not possible to actually join two tables without
using any condition.
if U would like to join two tables, then in source
qualifier transformation add all the port from two tables (
if both tables are from same database source) and write
down your join condition in user defined join option or
otherwise write down join condition inside the sql query
option with generated sql query.
if u use two different database source then use joiner to
join the two tables
