Answer 1

使用MAX（）

SELECT MAX(number) FROM number

Answer 2

You can simply use the Aggregate Functions. SELECT MAX(field_name) FROM table_name GROUP BY field_name;

You can also use "order by" clause with DESC and fetch the first row from result-set.

Answer 3

select MAX(number) from number;

Answer 4

MAX（）应该满足您的目的

Answer 5

If your field is a mixed varchar where some values begin with letters, you can use this solution:

SELECT max(number) FROM table WHERE number REGEXP '^[0-9]+$';

1. the function max() will take the highest value
2. the regex sorts out every value that not begins with a number

Answer 6

$hinteger=mysql_query("SELECT MAX(integer) FROM number");
