When we talk about joining two tables, we're usually talking about creating a Primary Key > Foreign Key relationship using TQL. Here is some documentation on how to do that:

Thanks for your reply.
This is basically Inserting data into 1 table from another table. So can we insert data into selected columns from similar selected columns of another table ?
e.g. i tried like:
insert into <table1> (table1.col1, table1.col3, table1.col5) select table2.col1, table2.col3, table2.col5 from <table2>;
But it didn't worked for me.
It worked. Thanks.
I have real time challenge. A table has more than 100+ cols and 200+ M rows. There is request to add another Indicator col.
So Adding new column and getting incremental load is fine.
But issue is how to do history correction here. Cann't we updated new col using PK in backend (TQL)?
As of now i am doing full truncate and load which is really time consuming.
