I have worked with SQL Server on and off for many years, but I don't think I recall ever seeing "ORDER BY [number]" as it appears in this question.

Could some kindly person explain this to me, because a clear explanation seems to be difficult to locate in the documentation, and in searches. This little issue was why I failed this question!

Many thanks

Order by [some number], this number indicates the order of the column in the Select clause.

Hope that would help you.

Like for example:

Select EmpId, EmpName, DeptId, DeptName

From SomeTable

Order by 2 -- this indicates that the result set will be sorted by column no. 2 in the Select clause which is 'EmpName'.

Hi kenneth,

In Order By we can specify integer representing the position of the column in the select list. The result set will be sorted based on the column. For further details pls refer

http://technet.microsoft.com/en-us/library/ms188385.aspx

Also FYI, Order By has no effect in this question, without sorting also you will get the same result, Its matter of Where clause.

I hope you are aware of Where clause will be applied before Order By.

I use numbers in my order by statements every day for short queries. It is faster than typing out long names and is especially nice when the column is some kind of calculatoni, function or case statement. I would not use them for production systems but for just checking around it my data they have been wonderful

You know, a simpler question is nice every once in a while. In fact, I found myself studying it to see what I missed. 🙂 Thanks.

Agree with Tom. We did have this "feature" used in production and it caused issues when an additional column was added to the select causing the "ORDER BY" to bring the records back in an order that was not expected.

However, as Tom mentioned, this is great when doing sub queries, unions or aggregates to do a quick check on the date without having to define aliases or use the calculation in the order by clause.

Good question. It's a shame that in my dazed state I knew the right answer, but picked the wrong one. Time to go have some magic caffeinated elixir.

Everything is awesome!
