If everything seems to be going well, you have obviously overlooked something.

Great question.. I nearly fell into the trap of selecting answer two by not reading the question properly! Thanks.

Good question - thanks.

Glad I took time to have the 2nd coffee before answering though

Thanks for the nice, easy question :-). I say it easy because I have seen it many times, on SQLSkills.com. Paul Randal has used this (INSERT INTO TableName DEFAULT VALUES) in many of his excellent articles :cool:.

Thank you for the thought provoking (for me at least) question!

I still don't get it. What does he mean by "insert the value"? :ermm:

Is it me, or does the "explanation" for (1) just repeat the incorrect syntax used in the question?

"IDENTITY_INSERT is used to set identity of a particular table. SET IDENTITY_INSERT ON/OFF "

"IDENTITY_INSERT is used to set identity of a particular table. SET IDENTITY_INSERT ON/OFF "

I think the explanation is incomplete. The table name should be specified in the SET INDENTITY_INSERT tablename ON/OFF command.

1. Query 1 fails because there are no values provided to INSERT.

2. Query 2 fails because the syntax for SET IDENTITY_INSERT requires a table name.

3. Query 3 succeeds because DEFAULT VALUES instructs SQL Server to insert the identity vale.

4. Query 4 fails because VALUES (DEFAULT) does not work for identity columns.

The answer should have included a reference to INSERT (http://msdn.microsoft.com/en-us/library/aa933206(v=sql.80).aspx) for completeness to explain why 1 and 4 fail while 3 succeeds.

Otherwise, a pretty good question.

Thanks for that sknox and thanks for the great question. I nearly fell into the Identity Insert trap and was about to select it before I took a second look and realized what it was missing.

Everything is awesome!
