Java SQLite-没有这样的表：使用CTE删除重复记录时

我已经创建了一个联系人表（姓名、电话、电子邮件），我有一些重复的记录要删除

WITH ContactsCTE AS (
    SELECT *, row_number() OVER ( PARTITION BY Name ORDER BY Name) as RowNumber
    FROM Contacts
)
SELECT * FROM ContactsCTE

当我使用SELECT时，它会显示它们的数据和行数，我想它可以正常工作

| Name | Phone |     Email      | RowNumber |
| Kris | 0123  | kris@gmail.com |     1     |
| Kris | 0123  | kris@gmail.com |     2     |
| Kris | 0123  | kris@gmail.com |     3     |
| Annie| 065   | annie@gmail.com|     1     |
| Bob  | 0123  | bob@gmail.com  |     1     |
| Bob  | 0123  | bob@gmail.com  |     2     |

但是如果我想删除它们

 WITH ContactsCTE AS (
        SELECT *, row_number() OVER ( PARTITION BY Name ORDER BY Name) as RowNumber
        FROM Contacts
    )
 DELETE FROM ContactsCTE WHERE RowNumber > 1

我得到这个信息： “结果：没有这样的表格：ContactsCTE”

在第1行：

SQLite不支持可更新的CTE。
您可以使用

不存在

：

DELETE FROM Contacts 
WHERE EXISTS (
  SELECT 1 FROM Contacts c  
  WHERE c.Name = Contacts.Name AND c.rowid < Contacts.rowid
);

请参阅。
结果:

DELETE FROM Contacts 
WHERE rowid > (
  SELECT MIN(rowid) FROM Contacts c  
  WHERE c.Name = Contacts.Name
);
