Max value in multiples columns

Hi, Is there any command as the "greatest" in MySQL that returns the maximum value in multiple columns?

Select * from ANIMALS

Place	Amount1	Amount2	Amount3	Amount4
1	1	5	0	1
2	1	3	8	2
3	1	4	2	4

My expected return:

Place	Max
1	5
2	8
3	4

max-value

Please take a look at the GREATER function. It does what you want for two inputs only, so you may need to combine several of those - something like GREATER(GREATER(a,b),GREATER(c,d)).
