If I wanted to create a table and make the columns equal the data from another table, can i do this??

Example:

I have a table called plantname_foods_USA_INC_Foodinfo
Under that table I have a column called contract_information_grower
The data in that column is:   grower 1

I want to create a table called plantname
a column called Farm
and data that equals the data from the contract_information_grower column in the plantname_foods_USA_INC_Foodinfo table.

Thanks!!

select contract_information_grower as Farm
into plantname
from plantname_foods_USA_INC_Foodinfo
where 1 = 0

The above will create the single-column table empty ... to create it with the actual data, remove the WHERE clause.

also, the above assumes that the table plantname doesn't exist yet.

Will this create a "Live" link??

If the data in the first table changes will it reflect to the new table??

no, what you are talking about is a view ... do this:

create view plantname
as
select contract_information_grower as Farm
from plantname_foods_USA_INC_Foodinfo

... then you can do this:  select * from plantname
and it will reflect changes in the actual table plantname_foods_USA_INC_Foodinfo

... and of course you can include additional columns (if you want) from the original table.

OR, if what you are looking for is all the distinct values from the original column (e.g. without repeats) then include the distinct keyword:

create view plantname
as
select distinct contract_information_grower as Farm
from plantname_foods_USA_INC_Foodinfo

Take your time!  Here's more ...

From your perspective a view is really nothing more than a named query.  So you can include in a view pretty much anything you can include in a SELECT query ... this includes GROUP BY, MIN, MAX, COUNT, as well as table joins.  In your case, if you want to include additional columns in your simple view, that's easy enough (this is just an example)...

create view plantname  -- fyi - use alter instead of create to change an existing view
as
select T.contract_information_grower as Farm,  T.columnA as MyNewNameA,  T.columnB as MyNewNameB
from plantname_foods_USA_INC_Foodinfo T

GO

select * from plantname
