Creare Unique/Primary Key when using SELECT* INTO

I have not been able to find a definitive solution ...

I am using Access 2010 to Pass a Make Table Query to SQL 2012 Express, which creates a new table based on a value in some column data and my query does work; however I always get an Access prompt to select a Primary/Unique Key.

Is there anyway to specify this Primary/Unique Key in the SELECT * INTO statement?

Here is my query ...

/****** Object:  Table [SQL_DB_Name].[dbo].[Raw_Data] Script Date: 10/21/2014 12:53:41 PM ******/
 
USE [SQL_DB_Name]
 
SELECT * INTO [ALL_Zero_ID_Rows]  FROM  [Raw_Data]
WHERE CAST([The_Number_in_This_Column] AS INTEGER) = 0;

No, you can't designate a PK or unique key as part of a SELECT ... INTO.

The low-brain solution here would be...

1.

Create the table, and include a column named id (or whatever floats your boat) that is an int identity(1,1) (Same as Access AutoNumber).  Set id as the primary key.

2.

Instead of SELECT INTO, do a DELETE FROM ALL_Zero_ID_Rows.  
TRUNCATE instead of DELETE works if you want to re-seed the id values starting at 1

3.

Do an insert, explicitly defining all rows, except for the id of course:

INSERT INTO ALL_Zero_ID_Rows (Col1, col2, col3) 
SELECT Col1, Col2, Col3 
FROM  [Raw_Data] 
WHERE CAST([The_Number_in_This_Column] AS INTEGER) = 0;

Open in new window

What is Raw_Data? If it's a table, then you could define a Primary Key on that, and the SELECT INTO should pick that up.

What about:

SELECT IDENTITY(int,1,1) as ID, * 
INTO [ALL_Zero_ID_Rows]  FROM  [Raw_Data]
WHERE CAST([The_Number_in_This_Column] AS INTEGER) = 0; 

Open in new window


and later:

ALTER TABLE [ALL_Zero_ID_Rows]
  ADD CONSTRAINT PK_[ALL_Zero_ID_Rows]
  PRIMARY KEY (ID);

Open in new window

I've never seen this happen.  What leads you to believe a PK constraint is copied into a table created using a SELECT ... INTO?

Not the Primary Key constraint, but rather the VALUE of the Primary Key ...
