SQL where field in vs. where field = with multiple ors?

Question

Which of these is better to use in regard to performance? ...in regard to readability / understandability? ...in regard to accepted standards?

SELECT *
FROM Wher         


        

Answer 1

I would say the first option involving in:

SELECT *
FROM Wherever
WHERE Greeting IN ('hello', 'hi', 'hey')

It is:

• much faster
• easier to read
• no need to use multiple or
• less typing
• easier to maintain in big queries
• widely used
