PDO Object is NULL

Go to solution Solved by requinix,

Recommended Posts

My code;

$sql = "SELECT SUM(IF(`submitdate` IS NULL , 1 , 0 )) as 'Survey Started But Not Completed' FROM `survey_$surveyid`";
$statement = $dbh->prepare($sql);
$result = $statement->fetch(PDO::FETCH_OBJ); //pass that data to an object

Is returning;

stdClass Object
    [Survey Started But Not Completed] => 

I need to set this to a vaule that I can actually print out on the screen... Like a "0" for example. At the moment it is just a NULL.
How do I do this??
These don't work;

$result  = 0;

$result = array(['Survey Started But Not Completed'] => "0");

  • Solution

Rather than SUM+IF, I'd use COUNT which will only count non-null values.

SELECT COUNT(`submitdate`) AS 'Survey Started But Not Completed' FROM `survey_$surveyid`

Side comment: tsk tsk for using multiple tables for multiple surveys. Should be just one table for everything.
