Hello, i need to create a table selecting from a view:

select *
into Mytable
from Myview

but i want Mytable to have an IDENTITY column that is not present in Myview...can i achieve this directly in the select statement without altering the table afterwards?

Tank you.

You can. Example:

SELECT *,
IDENTITY(INT,1,1) As NewColumn
INTO MyTable
FROM MyView

See documentation here: http://technet.microsoft.com/en-us/library/ms189838.aspx

if you want identity values to be generated based on order of particular column make sure you use something like


SELECT *,
ROW_NUMBER() OVER (ORDER BY YourColumn ) As NewColumn
INTO MyTable
FROM MyView

SELECT INTO with IDENTITY will not guarantee the order in which identity values are generated

Why do you want to create a new table? Can't you do it when selecting data from view?

SELECT *,
ROW_NUMBER() OVER (ORDER BY YourColumn ) As NewColumn
FROM MyView
