Difference between Create table Statements - response (6) by Adeel Chaudhry

The only difference is that .... in option 1 you have a leverage to tweak/select (correct) index.

I have seen scenarios where option 2 takes hours to process data .... and if you go with option 1 and correct selection of index .... it will just take a matter of seconds.

The latest occurance of the same happened at one of my clients yesterday. :)

HTH!
