Question

I have a table with the following columns, City, State, Zip, and Zone.
I want to update Zone with City – State – Zip with hyphens.

Is there a way to do this in SQL without grabbing all the records and iterating through the results and doing an update statement for each one?

Answer 1

update table set zone = city + '-' + state + '-
 + Zip

Note if the datatypes are different you might need to do something like

update table set zone = cast(city as varchar(50)) + '-' + cast(state as varchar(50)) + '-
 + cast(Zip as varchar(50))
