for example have column table 1 , column table 2, supposed coincide. columnatable1 being identification number , columnatable2 being description.

i tried got error...

alter table dbo.committedtbl add v_vendorname nvarchar(200) v_venkey = v_vendorno

it tells me have incorrect syntax... know how accomplish this?

alter table dbo.committedtbl add v_vendorname nvarchar(200);  go  update c set c.v_vendorname = a.v_vendorname committedtbl c join tablea on c.v_venkey = a.v_vendorno;  go
