Question

I have this 3 sql questions:

$producent = mysql_fetch_array(mysql_query("
            SELECT FieldValue 
            FROM `xy8vx_rsform_submission_values`
            WHERE SubmissionId = '$id' AND FieldName = 'Producent'
            "));

$model = mysql_fetch_array(mysql_query("
            SELECT FieldValue 
            FROM `xy8vx_rsform_submission_values`
            WHERE SubmissionId = '$id' AND FieldName = 'Model'
            "));

$nr_ser= mysql_fetch_array(mysql_query("
            SELECT FieldValue 
            FROM `xy8vx_rsform_submission_values`
            WHERE SubmissionId = '$id' AND FieldName = 'Nr seryjny'
            "));

Is it posible to get those 3 values with one sql question?

Answer 1

Yes, use IN clause.

 SELECT FieldName , FieldValue 
 FROM `xy8vx_rsform_submission_values`
 WHERE SubmissionId = '$id' AND FieldName IN ('Producent', 'Model', 'Nr seryjny')

And of course you need to use a loop to fetch the result.

// $sql is the above sql
$res = mysql_query($sql);
$result = array();
while ($row = mysql_fetch_assoc($res)) {
  $result[$row['FieldName']] = $row['FieldValue'];
}
print_r($result);
