当我在HTML标记内回显数据时，如何获取数据值？

$database = new Database();
$db = $database->getConnection();   


    $query = "SELECT 
          po.no_po, 
          barang.nama_barang,

          po.keterangan, 
          surat_pengantar.tgl_kirim, 
          gudang.nama_gudang,
           barang.harga_jual * po.qty AS total_harga
        FROM 
          public.po, 
          public.barang, 
          public.klien,

          po.no_po = good_receipt.no_po AND

如果我从查询中删除no_po =：no_po，结果只从一个no_po获取值，同时我希望结果基于no_po存在。我声明了变量，但标签HTML中的echo数据并不起作用。结果应该基于no_po获得值。任何人都可以帮我解决这个问题吗？

Answer 1

您可能想要在某处查看LEFT JOIN。可能发生的是，在你隐式使用的所有连接中，你正在寻找的那个确实存在的行已经被连接排除了。隐式连接是内连接，内连接要求所有表都与匹配值一起出现。因此，如果除了最后一个'surat_pengantar'之外所有表都能够加入，它将使第一个匹配no_po的表的结果无效。这是因为你的po.no_po = surat_pengantar.no_po的条件是假的。
