this question helped me create custom column, how go in defining should go in column?

you can define column setting [what want show in column] as(optional) [the name want give new column]. example:

select      t1.id,     t1.amount,     t1.status,     t1.addedby,     t1.addedon,     concat(t1.id,t1.status) new_column1,     'output sample' new_column2,     1+3 new_column3 table1 t1

i hope can you. regards
