data array is dropped if the column is null or empty in Database

Question

My table contains columns with null values. But when I try to retrieve the data set in to a variable,data array is dropped if the column is null or empty.

lets say as I have 4 columns

[cid] => 357
[smcoordinator] => 
[title] => Null
[cname] => Maddox Adam  Portland

And my function is,

function getValue($data){

      $dataset = $data['dataset']['result_set'];
      print_r($dataset);

      //somecode...
}

resut in the print_r

[cid] => 357
[smcoordinator] => 
[cname] => Maddox Adam  Portland

How can I get the Null column to my dataset?

Answer 1

Try replacing NULL with something else

$dataset = $data['dataset']['result_set'];
$Title = $dataset['title'];

//if title has no value give it one 
if (!$Title)
{
  $Title = "No Value";
}

then rebuild your result set array

$data['dataset']['result_set']['title'] = $Title;

Let me know if it works!

Answer 2

Message: Undefined index: title

Ok in MYSQL itself check that the title column is not a key column or index column as these columns cannot be null and make sure NOT NULL is not ticked

And that SQL error tells you its looking for an Index
