sql - Mysql max value from 3 different columns

Question

Is there any way to find maximum value of 3 different columns? I'm trying to find records with any of 3 columns value higher than specified value and trying to avoid making something like this in query:

column1 > 69 or column2 > 69 or column3 > 69

Table structure is like this:

id | column1 | column2 | column3
1  |   5     |    4    |    3
2  |  70     |    1    |    65
3  |  66     |    3    |    90

And select like this:

select id from tablex where column1 > 69 or column2 > 69 or column3 > 69

-- but with better query, a bit prettier like this (it doesn't work of course)

select id from tablex where MAX(column1, column2, column3) > 69

Answer 1

you need to use GREATEST

like that

    select id from tablex where GREATEST(column1, column2, column3) > 69
