用mysql查询生成大型html表格非常慢 - 4000+行查询

Question

表格创建超过3分钟后我发送请求数据库表中有大约4000条记录，我认为可以通过JavaScript解决，但是我可以通过JavaScript解决我不知道如何。感谢

$query = "SELECT * FROM tblRazduzeniUgovori"; 
if ($result = mysqli_query($con, $query)) { 
    while($row = mysqli_fetch_array($result)) 
    { 
      echo "<tr>"; 
      echo "<td><input type='checkbox' name='brojUgovora[]' value='" . $row['Broj'] . "'/></td>"; 
      echo "<td style='font-size:15px;'>" . $row['Broj'] . "</td>"; 
      echo "<td>" . $row['Kontrolni_Broj'] . "</td>"; 
      echo "<td><span class='label label-success' style='width:90%;'>"; 
      foreach ($kor_id as $key => $val) { 
        if ($val == $row['Korisnik_ID']) { 
         echo $kor_ime[$key] . " " . $kor_prezime[$key]; 
         break; 
         } 
        } 
      echo "</span></td>";

      echo "</tr>"; 
    } 
    } 
    mysqli_close($con);

Answer 1

第一查询减少到只问你想为你的表中的字段，如：

$query = "SELECT Broj,Kontrolni_Broj FROM tblRazduzeniUgovori " 

（显然添加字段​​，你需要选择休息）

第二次使用连接，而不是吨的回声。

$query = "SELECT * FROM tblRazduzeniUgovori"; 
$output = ''; 
if ($result = mysqli_query($con, $query)) { 
    while($row = mysqli_fetch_array($result)) 
    { 
      $output .= "<tr>"; 
      $output .= "<td><input type='checkbox' name='brojUgovora[]' value='" . $row['Broj'] . "'/></td>"; 
      $output .= "<td style='font-size:15px;'>" . $row['Broj'] . "</td>"; 
      $output .= "<td>" . $row['Kontrolni_Broj'] . "</td>"; 
      $output .= "<td><span class='label label-success' style='width:90%;'>"; 
      foreach ($kor_id as $key => $val) { 
        if ($val == $row['Korisnik_ID']) { 
         $output .= $kor_ime[$key] . " " . $kor_prezime[$key]; 
         break; 
         } 
        } 
      $output .= "</span></td>"; 
      $output .= "<td>" . $row['Datum_Razduzenja'] . "</td>"; 
      $output .= "<td>" . $row['Ime_Kupca'] . "</td>"; 
      $output .= "<td>" . $row['Ime_Prodavca'] . "</td>"; 
      $output .= "<td>" . $row['Cijena'] . " KM</td>"; 
      $output .= "<td style='padding:6px;'><span class='label label-   info' style='width:90%; text-align:center;'><a href='/crm/ugovori/" . $row['Slika'] . "' style='color:white;'>" . $row['Slika'] . "</a></span></td>"; 
      $output .= "</tr>"; 
    } 
    } 
    mysqli_close($con); 
    echo $output; 
    }
