Copy table data from live to dev server

I have two existing Product tables -- one on our dev server, one on our live server.

I would like to essentially "copy down" all the Products FROM the live server to dev, getting rid of all the product data that is currently in the dev table.

How can I copy the products from live to dev, so that the primary keys (int) are all the same etc?

1) Truncate table Product on Dev

2) A) Use SSIS package for copying the table from production to development environment. (OR)
    B) Create linked server on development server and use the below statement for copying Product table:

             INSERT INTO PRODUCTTABLE SELECT * FROM PRODUCTIONSERVER.DB1.PRODUCTTABLE

   (OR)
    c) Use OPENROWSET

Below is the link for using linked server or OPENROWSET:

Since we are truncating the product table in development environment, we dont have to worry about same primary key unless you have used identity column.

You should consider 2.A from marappan suggestion above.
I don't know how tight your production environment is but i do not ever allow linked servers on development servers to be defined agains a production environment.

In regards to the truncate statement  I want to expand on the statement by marappan.
The use of truncate on a table with a identity column will cause a reset of the identity seed back to the base value of when the table was created which in most cases would be 1.

So if you are testing inserts and your identity column has a unique index or is the primary key the insert will fail if there is already a record with that value

You will need to either reseed the value (see BOL for DBCC CHECKIDENT) or enable identity insert as part of your ssis package.

If it's not too huge, I find it easiest to do a restore from database. in ssms right click databases, restore, from db.

why the requirement to maintain keys?

the two environments are separate so you would expect the keys to be different...

if you want to maintain keys ,,, then don't you have a bigger problem in development in that you will need to remap all your other dependant tables  which use the product key...
