使用GROUP BY語句，但仍然顯示重複

Question

試圖從表中調出每種類型的項目，我已經在我的sql查詢中按語句放入組，但它仍然回顯出重複的數據。

下面的代碼和數據庫示例

<?php 
$con=mysqli_connect("localhost","root","root","test"); 
$sql = "SELECT * FROM testing GROUP BY Name"; 
$result = mysqli_query($con, $sql); 
while ($row = mysqli_fetch_array($result)) { 
    echo $row['name']; 
    echo "<br>"; 
} 
?> 

Answer 1

這裏是你可以嘗試代碼..

<?php 
    $con=mysqli_connect("localhost","root","root","test"); 
    $sql = "SELECT distinct name, Record_ID, Shop_ID FROM testing"; 
    $result = mysqli_query($con, $sql); 
    while($row = mysqli_fetch_array($result)) 
    { 
     echo $row['name']; 
      echo "<br>"; 

    } 
?> 

Answer 2

試試這個： -

Select distinct name from testing;
