Easy one 🙂

The question should ask "logical processing order", as the optimizer can throw things around in order to get better performance, as long as the result is the same as the logical processing order.

Simple question.....

Is any answer verification doing before posting the questions ?

nice simple question... the answer selection is a bit of a give away though 😉

but, good thing to know when trying to optimize queries.

Having only one option that started with FROM made it very straightforward. Useful to still refresh the memory with the sequence so thanks for the question (and easy point!) 🙂

Nice question though I would have prefered more than one option to have started with from as this would have made it more of a test.

Thanks kranthi1.aprdc for the question. I see you are relatively new to the site. So good to see you jumping in with a QotD contribution. As others have suggested, this one might have been a bit too easy, with only one answer that started with "FROM". But, you're pointed in the right direction.

Good question. It is good to know because you can use alias in the Order By clause but not the Where clause. The Select, and definition of an alias, is after where by before Order By

More answers starting with From would have been more trickier, I think that gives the answer away.

At least I was not the only one who noticed the first and third option were the same...
