MySQL Select minimum/maximum among two (or more) given values

Question

Is it possible to SELECT the minimum or maximum among two or more values. I\'d need something like this:

SELECT MAX_VALUE(A.date0, B.date0) AS d         


        

Answer 1

Just watch out if NULL is likely to be in a field value ...

SELECT LEAST(NULL,NOW());

and

SELECT GREATEST(NULL,NOW());

both return null, which may not be what you want (especially in the case of GREATEST)
