Great question, I had to think about it, thanks!

Though I would have to say I would have made one of the choices "One row displaying the value 1", as that would have made one of the incorrect choices more plausible.

Thanks, UMG!

And you are right, that would have been a better distractor. I'm not sure why I included the "one row, value 2" option. It's a while back I made this question; if I recall correctly, the HAVING clause first tested for >= 5, and I changed this later but apparently forgot to change the distractor.

thanks Hugo, i really didnt know this. I was assuming that HAVING must have a corresponding GROUP by.

Good Question, we will be always thinking that having can be used only with the Group By clause.

Nice question! I got it wrong, because I misinterpreted the HAVING clause; I read it as WHERE Col >= 5, and that leads to a value of 2. I knew the behaviour of HAVING though, but I wanted to have it play a role in this query. But alas, it's only to confuse the reader...

So there can always be logic in an incorrect answer, as long as you read the question wrong Smile

I thought it would be an empty result but wasn't positive decided to "test" and created the table. I got this message on executing the query:

Msg 8121, Level 16, State 1, Line 4
Column 'QotD.col2' is invalid in the HAVING clause because it is not contained in either an aggregate function or the GROUP BY clause.

This is from BOL:

"The HAVING clause is typically used together with the GROUP BY clause to filter the results of aggregate values. However, HAVING can be specified without GROUP BY. The HAVING clause specifies additional filters that are applied after the WHERE clause filters. These filters can be applied to an aggregate function used in the select list."

I don't know if the version of SQL makes a difference, but I am using SQL Server 2008 R2
