Question

Ive got the query below :

$sql = "SELECT `scanners`.`KordNo`, `scanners`.`BundleNumber`
  FROM `scanners`, `TWOrder`, `Stock`
  INNER JOIN `TWORDER` ON `scanners`.`KordNo` = `TWOrder`.`KOrdNo`
  AND `scanners`.`Date` = '" . $date . "'
  INNER JOIN `Stock`  ON `TWOrder`.`Product` =`Stock`.`ProductCode`
  AND `Stock`.`ProductGroup` NOT BETWEEN 400 AND 650  
  AND `scanners`.`Scanner` IN (
  ORDER BY `scanners`.`KordNo` ASC";
  foreach($scanner as $x) 
  {$sql .= $x . ",";}
   $sql .= "0);";
  // And query the database
  $result = mysql_query($sql);
  while($row = mysql_fetch_array($result))
  $return[] = $row;
}

When i echo the sql on php my admin i get the error not a unique table/alias stock;

can someone advise?

Since you’re using explicit JOINs, drop the other two tables off of the FROM clause.

...
FROM `scanners`
INNER JOIN `TWORDER` ON `scanners`.`KordNo` = `TWOrder`.`KOrdNo`
...
