Question

I know I’m just making a simple error here. I have a column called ParentEventID that sometimes has a NULL value. I need to retrieve rows with that value. My code is only retrieving rows where ParentEventID = “0” right now.

$UserID = "118";

$query = "SELECT * FROM  events  WHERE UserID='$UserID' AND ParentEventID = 'NULL'";

$result = mysql_query($query);

while($row = mysql_fetch_array($result))
  {
    echo $row['UserID'] . " ".$row['EventName']. " " . $row['ParentEventID'];
    echo "<br />";
  }

Thanks for the help!

Answer 1

you want to use IS NULL instead of = 'NULL'
