Adding two values


Canman2005

Recommended Posts

Dear all

I have a simple sql statement which adds up all the numbers in one colum of my database, the code I used is

[code]$sql ="SELECT SUM(cost) as 'cost' FROM results WHERE resultid = '$resultid'";
$sql = @mysql_query($total,$connection) or die(mysql_error());[/code]

As well as the colum "cost" I also have another colum in my database called "costtwo"

How can I get the statement to add these two coloums (cost + costtwo) and then total the rows up? Basically like it does now, but adding costtwo before it tots up the rest of the values

Is this easy?

Thanks

Dave

Hi,

You mean something like this?
[code]
$sql ="SELECT SUM(cost + costtwo) as 'cost' FROM results WHERE resultid = '$resultid'";
$sql = @mysql_query($total,$connection) or die(mysql_error());
[/code]

Yea, thats realy easy, isn't it?
