Mysql 具有多个选择和分组依据的查询

我将计算总面积的记录，其中状态将不同，如“待定”、“发送信息”、“分组查询的PTP”和多个select查询，但结果未得到，请帮助我

SELECT AREA, 
       SUM(CASE WHEN STATUS = 'PENDING' THEN 1 ELSE 0 END) AS PENDING, 
       SUM(CASE WHEN STATUS = 'SENT INFO.' THEN 1 ELSE 0 END) AS cnt, 
       SUM(CASE WHEN STATUS = 'PTP' THEN 1 ELSE 0 END) AS PTP
  FROM prospectmaster 
 WHERE ZONE = 'AHMEDABAD' 
 GROUP BY AREA;

我的问题是：

SELECT AREA, 
(SELECT COUNT( * ) FROM prospectmaster WHERE ZONE = 'AHMEDABAD' && STATUS = 'PENDING' GROUP BY AREA) AS PENDING, 
(SELECT COUNT( * ) FROM prospectmaster WHERE ZONE = 'AHMEDABAD' && STATUS = 'SENT INFO.' GROUP BY AREA) AS CNT 
FROM prospectmaster 
WHERE ZONE = 'AHMEDABAD' GROUP BY AREA  

我想知道这种结果

AREA       PENDING    INFO SENT     PTP 
AHMEDABAD   1          2             1    
GANDHINAGAR 1          5             4
KHEDA       3         10             9

我想在查询中有些问题，但我不明白。所以，请帮助我

SELECT AREA, 
       SUM(CASE WHEN STATUS = 'PENDING' THEN 1 ELSE 0 END) AS PENDING, 
       SUM(CASE WHEN STATUS = 'SENT INFO.' THEN 1 ELSE 0 END) AS cnt, 
       SUM(CASE WHEN STATUS = 'PTP' THEN 1 ELSE 0 END) AS PTP
  FROM prospectmaster 
 WHERE ZONE = 'AHMEDABAD' 
 GROUP BY AREA;

如果

状态

具有“发送信息”。使用

在数据库中记录，因为这是mysql，您只需执行以下操作：

  SELECT AREA, 
         SUM(if(STATUS='PENDING',1,0)) AS PENDING, 
         SUM(if(STATUS='SENT INFO',1,0)) AS "INFO SENT",
         SUM(if(STATUS='PTP',1,0)) AS PTP 
    FROM prospectmaster 
   WHERE ZONE = 'AHMEDABAD' 
GROUP BY AREA;

SELECT
  AREA, 
  SUM(STATUS = 'PENDING') AS PENDING, 
  SUM(STATUS = 'SENT INFO.') AS SENT_INFO,
  SUM(STATUS = 'PTP') AS PTP
FROM prospectmaster 
WHERE ZONE = 'AHMEDABAD' 
GROUP BY AREA

这是因为在mysql中，true为1，false为0，所以求和一个条件将计算其true的多少倍

我认为它应该是

“发送信息”

而不是

“发送信息”。
