Nice Question...

Great question.
Although the IDENTITY property doesn't always transfer:
When an existing identity column is selected into a new table, the new column inherits the IDENTITY property, unless one of the following conditions is true:
*The SELECT statement contains a join, GROUP BY clause, or aggregate function.
*Multiple SELECT statements are joined by using UNION.
*The identity column is listed more than one time in the select list.
*The identity column is part of an expression.
*The identity column is from a remote data source.

The first and the hardest SQL statement I have wrote- "select * from customers" - and I was happy and felt smart. -
Took a lot of thinking to work out all those double negatives!

On two occasions I have been asked, "Pray, Mr. Babbage, if you put into the machine wrong figures, will the right answers come out?" ... I am not able rightly to apprehend the kind of confusion of ideas that could provoke such a question.

Yes, initially I have drafted the question straight forward but it looks very simple. Deliberately make it complicated by tricky language to make challenging.
Usually everyone knows correct answer but when things presented differently; makes it difficult.
Appreciate all your efforts and comments.

The answers appear to suggest that the following is true:
"The columns in new_table are created in the order specified by the select list."
However, http://technet.microsoft.com/en-us/library/ms188029.aspx says...
"Specifying an ORDER BY clause does not guarantee the rows are inserted in the specified order."
Am I misreading something?

Hello Koen,
This comment was expected for this question. 🙂
Usually we do not consider exceptions hence for IDENTITY property too we have not consider conditions.
Thank you.
