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

Try this:

SELECT GREATEST(A.date0, B.date0) AS `date0`,LEAST(A.date0, B.date0) AS `date1`
  FROM A 
  JOIN  B
    ON A.id = B.role;
