/* This next statement is going to use code to change the “current” database

USE AdventureWorks2008;
/* This next statement declares our working table.
** This particular table is actually a variable we are declaring on the fly.
*/
DECLARE @MyTable Table
(
SalesOrderID int,
CustomerID char(5)
);
/* Now that we have our table variable, we’re ready to populate it with data
** from our SELECT statement. Note that we could just as easily insert the
** data into a permanent table (instead of a table variable).
*/
INSERT INTO @MyTable
SELECT SalesOrderID, CustomerID
FROM AdventureWorks2008.Sales.SalesOrderHeader
WHERE SalesOrderID BETWEEN 44000 AND 44010;
-- Finally, let’s make sure that the data was inserted like we think
SELECT *
FROM @MyTable;
This should yield you results that look like this:
(11 row(s) affected)
SalesOrderID CustomerID
------------ ----------
44000 27918
44001 28044
44002 14572
44003 19325
44004 28061
44005 26629
44006 16744
44007 25555
44008 27678
44009 27759
44010 13680
(11 row(s) affected)
The first instance of (11 row(s) affected) we see is the effect of the INSERT...SELECT statement at
work. Our SELECT statement returned three rows, so that’s what got INSERTed into our table. We then
used a straight SELECT statement to verify the INSERT.
