刪除重複的行合併單元格值的MySQL

我有三列一個MySQL表：刪除重複的行合併單元格值的MySQL

Name   | Email    | BDate 
--------------------------------------------------------- 
John Doe  | [email protected] | June 1, 1980 
Kelly Smith |      | June 2, 1983 
Richmond White | [email protected] | 
John Doe  |      | 
Kelly Smith | [email protected] | 
Richmond White |      | June 3, 1984

我想要做的就是刪除重複的名稱，合併單元格的值。我想我的表看起來像這樣：

Name   | Email    | BDate 
--------------------------------------------------------- 
John Doe  | [email protected] | June 1, 1980 
Kelly Smith | [email protected] | June 2, 1983 
Richmond White | [email protected] | June 3, 1984

我的查詢將如何返回我的慾望表？

在此先感謝！

查詢：

SQLFIDDLEExample

SELECT t1.Name, 
     MAX(t1.Email) Email, 
     MAX(t1.BDate) BDate 
FROM Table1 t1 
GROUP BY t1.Name

結果：

|   NAME |    EMAIL |  BDATE | 
------------------------------------------------------ 
|  John Doe | [email protected] | June 1, 1980 | 
| Kelly Smith | [email protected] | June 2, 1983 | 
| Richmond White | [email protected] | June 3, 1984 |

謝謝，這就是我需要的。非常感謝。 – jules

一種選擇是使用下面的查詢，以創建一個新表，然後刪除舊錶：

SELECT Name, GROUP_CONCAT(Email) AS Email, GROUP_CONCAT(BDate) AS DBate 
FROM YourTable 
GROUP BY Name
