通過結合組和計數的MySQL

我需要找出使用組表中的所有狀態：通過結合組和計數的MySQL

SELECT status FROM table GROUP BY status

再算上結果發現

SELECT count(id) WHERE status = [STATUS]

因此，像一個表：

+--------------------+ 
| ID | STATUS | NAME | 
+--------------------+ 
|0001| BOUGHT | JOHN | 
---------------------- 
|0002| BOUGHT | JOHN | 
---------------------- 
|0003| CANCEL | JOHN | 
---------------------- 
|0004| BOUGHT | JOHN | 
---------------------- 
|0005| CANCEL | JOHN | 
--------------------- 
|0006| BOUGHT | JOHN | 
---------------------- 
|0007| BOUGHT | JOHN | 
---------------------- 
|0008| SAVE | JOHN | 
---------------------- 
|0009| SAVE | JOHN | 
---------------------- 
|0010| BOUGHT | JOHN | 
---------------------- 
|0011| SAVE | JOHN | 
----------------------

將產生類似的結果：

STATUS | COUNT 
--------------- 
SAVE | 3 
BOUGHT | 6 
CANCEL | 2

任何幫助表示讚賞。

'FROM表組選擇地位status'是一個昂貴的方式得到的結果相同'SELECT DISTINCT status FROM table'。 – axiac

使用下面的查詢：

SELECT status, count(id) as CNT FROM table GROUP BY status

僅僅通過狀態組這會給你想要的結果

select status, count(id) as COUNT FROM table GROUP BY status
