Question

I like to compare a date (extract from database with a null value (0000-00-00).
I try to do like that:

$dateValue = $row_recordset3['ttDateEnvoiDEP'];

if ($dateValue === '0000-00-00') {                  
    $dateEnvoiDEP = "CURRENT_DATE()";                   
}
else {
    $returnOK .= $dateValue;
    $dateEnvoiDEP = $row_recordset3['ttDateEnvoiDEP'];
} 

But it doesn’t work, do you know why?

Answer 1

why don’t you do it directly in your SQL query, something like this,

SELECT   IF(ttDateEnvoiDEP = '0000-00-00', CURDATE(), ttDateEnvoiDEP) 
             as `ttDateEnvoiDEP`,
FROM     ...
WHERE    ...
