Php MYSQL按字母顺序排序不起作用

我有一个数据库，里面有一张满是设施名称的表格。我试图按设施名称的字母顺序输出设施，并显示与之关联的帐户

设施表如下所示：

id | account_id | facility_name |
 2 |     2      |  Facility A   |
 3 |     2      |  Facility B   |
 4 |     2      |  Facility A   |

account_id | account_name |
    1      |  Account 1   |
    2      |  Account 2   | 
    3      |  Account 3   | 

 facility_name | account_name |
  Facility A   |  Account 1   |
  Facility B   |  Account 1   | 

ORDER BY `facility_name` ASC

Accounts表如下所示：

id | account_id | facility_name |
 2 |     2      |  Facility A   |
 3 |     2      |  Facility B   |
 4 |     2      |  Facility A   |

account_id | account_name |
    1      |  Account 1   |
    2      |  Account 2   | 
    3      |  Account 3   | 

 facility_name | account_name |
  Facility A   |  Account 1   |
  Facility B   |  Account 1   | 

ORDER BY `facility_name` ASC

我试图让我的输出像这样：

id | account_id | facility_name |
 2 |     2      |  Facility A   |
 3 |     2      |  Facility B   |
 4 |     2      |  Facility A   |

account_id | account_name |
    1      |  Account 1   |
    2      |  Account 2   | 
    3      |  Account 3   | 

 facility_name | account_name |
  Facility A   |  Account 1   |
  Facility B   |  Account 1   | 

ORDER BY `facility_name` ASC

我正在使用PHP将其输出到一个表中，所以这里有点像：

$sql = "SELECT * FROM facility INNER JOIN account ON account.account_id = facility.account_id WHERE facility.account_id = '". $q ."' ORDER BY 'facility_name'";

echo   "<table>
            <tr>
            <th>Facility Name</th>
            <th>Account Name</th>
            </tr>";
        while ($row = mysqli_fetch_array($data)) {
            echo "<tr>";
            echo "<td>" . $row['facility_name'] . "</td>";
            echo "<td>" . $row['account_name'] . "</td>";
            echo "</tr>";
        }
echo "</table>";

$sql=“从account.account\u id=facility.account\u id，其中facility.account\u id=”上的设施内部联接帐户中选择*”$q.“‘设施名称’下的订单”；
回声“
设施名称
帐户名
";
while（$row=mysqli\u fetch\u数组（$data））{
回声“；
回显“$row['facility_name']”；
回显“$row['account_name']”；
回声“；
}
回声“；

然而，这似乎并不是对我的表和设施名称进行排序，它只是按照输入的顺序进行输出

如何输出数据，使其也按“设施名称”排序？

问题就在这里：

ORDER BY 'facility_name'";

您实际上是通过字符串“facility_name”进行订购

去掉下面的引号：

ORDER BY facility_name";

---

引述是错误的。它应该是不带引号的字段名：

ORDER BY facility_name

或使用反勾号（允许，但仅当字段名中有空格或其他特殊字符时才需要）：

---

如果您像这样使用普通引号，它将是一个字符串文字，因此您只需按文本

'facility\u name'

排序，该文本对每行都具有相同的常量值，因此排序没有效果。

将其添加到查询中应该可以：

ORDER BY facility_name ASC

如果没有，请尝试将其放在记号内，如下所示：

id | account_id | facility_name |
 2 |     2      |  Facility A   |
 3 |     2      |  Facility B   |
 4 |     2      |  Facility A   |

account_id | account_name |
    1      |  Account 1   |
    2      |  Account 2   | 
    3      |  Account 3   | 

 facility_name | account_name |
  Facility A   |  Account 1   |
  Facility B   |  Account 1   | 

ORDER BY `facility_name` ASC

---

是的，知道了，谢谢，我会接受的，当我可以的时候！您没有检查查询中的错误，它会抛出您所犯的语法错误。
