As with so many types of testing, you must also test your "made up" questions as well. This question actually has two correct answers... made up or not... Wink

--Jeff Moden

RBAR is pronounced ree-bar and is a Modenism for Row-By-Agonizing-Row.
First step towards the paradigm shift of writing Set Based code:
     Stop thinking about what you want to do to a row... think, instead, of what you want to do to a column.
Although they tell us that they want it real bad, our primary goal is to ensure that we dont actually give it to them that way.
Although change is inevitable, change for the better is usually not.
Just because you can do something in PowerShell, doesnt mean you should. Wink

I kept looking for checkboxes to select both correct answers. Lucky I guessed right which one you were looking for. Although I suppose you could argue that the syntax for the other "correct answer" was a little off because you can't query "sys.columns.is_identity", you'd actually do "select * from sys.columns where is_identity=1".

Hmmm... it depends on your point of view. If you view the syntax literally, then only one answer is correct.

However, if you view the possible answers as pseudocode, then "Query sys.columns.is_identity for a value of 1" can be interpreted:

SELECT [object_id], [name] FROM sys.columns
WHERE is_identity = 1



This is also correct.

Thanks!

What about using sp_columns on the table? That has a column with identity yes/no...

There Is no such a way when database engine is SQL server 2000.the following query returns error:
SELECT [object_id], [name] FROM sys.columns
WHERE is_identity = 1

I agree that there should be 2 correct answers.

These types of problems should be taken care. Otherwise it becomes very confusing. In another forum we already discussed about these problems.
