以下脚本成功地允许我搜索日期并在“JOBS”表中显示与时间相关的所有信息,这些信息已放在存储在“orderno”表中的系统上。

// PUT your connection data HERE !

$DB_SERVER = 'localhost';
$DB_NAME = 'database';
$DB_USER = 'username';
$DB_PASS = '*********'; 

// opening a connection to the database
try
{
  $db = new PDO("mysql:host=".$DB_SERVER.";dbname=".$DB_NAME.";charset=utf8", $DB_USER,    $DB_PASS, array(PDO::ERRMODE_EXCEPTION, PDO::FETCH_ASSOC) );
}
   catch(PDOException $e)
{
echo $e->getMessage();
   }

$sql = 
"SELECT o.JobNumber, o.date_col, Job_Title, Handler
FROM orderno o
INNER JOIN JOBS j on (o.JobNumber = j.JobNo)
WHERE date_col = ?";

  // preparing the query
  $stmt = $db->prepare($sql);

 // assembling the requested date
  $date = $_GET['year'] . '-' . $_GET['month'] . '-' . $_GET['day'];

// setting the parameter value  
$stmt->bindParam(1, $date, PDO::PARAM_STR);

// executing the query 
$stmt->execute();

// returning the resultset
$resultSet = $stmt->fetchAll();

if ( count($resultSet) == 0 )     {
    echo "No records found for date ".$date;
}
   else {
   echo '<table border=1>';
    // writing the table header
echo '<tr>';
foreach($resultSet[0] as $key => $value) {        
    if (!is_numeric($key)) {
    echo '<TH>'.$key.'</TH>';
    }
}
echo '</tr>';
// writing the rows...
foreach($resultSet as $row) {
    echo '<tr>';
    // each field...
    for($i = 0; $i < $stmt->columnCount(); $i++) {
        echo '<td>'.$row[$i].'</td>';
    }
    echo '</tr>';
    }
echo '</table>';
   }

但是,在“JOBS”表中,“处理程序”存储为数字。在“处理程序”表中,它显示相关编号,但将其与全名匹配。

如何将此脚本链接到“处理程序表”并在此列中显示 FullName 而不是存储在 JOBS 表中的数字?

谢谢!

您可以进行另一次加入INNER JOIN HANDLER h ON h.row_id = j.Handler,然后只需FUllNameSELECT

SELECT o.JobNumber, o.date_col, j.Job_Title, h.FullName
FROM orderno o
INNER JOIN JOBS j ON o.JobNumber = j.JobNo
INNER JOIN HANDLER h ON h.row_id = j.Handler
WHERE o.date_col = ?
