Selecting maximum and minimum values across columns in MySQL 

This is done using the greatest() and least() functions respectively.  So to find the max across three columns then you would use something like:

select greatest(col1,col2,col3) from mytable;

To find the minimum you would use:

select least(col1,col2,col3) from mytable;
