I have a table with one column, want to add a new column and map some information to this column from another table:

I dont know how to create this query:

select a.hs_code
,'' a.hs_code_desc -------this is the new column in table a

update a
set a.hs_code_desc = b.hs_code_desc
from transportation.dev.hsWithoutNaics a
inner join trade.dev.export_concord2 b
on a.hs_code = b.hs_code

it should be

ALTER TABLE  transportation.dev.hsWithoutNaics ADD hs_code_desc varchar(100) NULL

I've assumed datatype as varchar. make sure you use correct datatype instead
