esthera, you mean something like the following?


INSERT INTO NewTable
SELECT *
FROM OldTable

yes -- will that work if the newtable wasn't yet created or do I have to create it first?
Will it keep primary keys and identities and defaults?

Esthera, you should create the table before the INSERT.

Nope ...

SELECT * INTO TableToBeCreated FROM MyExistingTable

will create a new table with appropriate datatype for each column.

Otherwise you need to do

CREATE TABLE MyNewTable
(
...
)

INSERT INTO MyNewTable
SELECT *
FROM MyOldTable

SQL Server has a number of ways that you can use to get a "script" of the existing table, and then you can just "find&replace" to make a new script. This can include all indexes, PKs, defaults, IDENTITY, extended properties and so on
