How to get max number in a column?

I'm been trying to find a example of how to get a max number in a column.What I want to do is, find the MAX number of a column in a TABLE_A, points(column). I want to output this MAX number for example

<cfoutput>
    <tr>
    <th><div align="right">#maxnumber#</div></th>
    </tr>
    </cfoutput>

Not sure if this is the way to output, But I just want one number(the MAX) , not an array of the column.

thanks for your help, new to ColdFusion.

You can do something like this to get the top X from your query and then output them accordingly

<cfquery name="maxQuery">
SELECT TOP 2 points
FROM table_a
ORDER BY points DESC
</cfquery>

<cfoutput query="maxQuery">
  #maxQuery.currentRow# - #maxQuery.points#<br>
</cfoutput>

select max(points) from TABLE_A

for getting second max number you can do like below

select max(point) as secondmax from TABLE_A where point<(select max(point) from TABLE_A)
