Question

我有以下查询给出以下结果

SELECT ttable.* 
FROM  ( SELECT 
            `STATUS`, 
            `TELCOID`,                
            COUNT(*) smsCount                 
        FROM `smsout` 
        WHERE `STATUS`  = 'Send'        
            AND (RECEIVEDTIME BETWEEN DATE_SUB(NOW(), INTERVAL 1000000 MINUTE) AND NOW())
        GROUP BY  `STATUS` , `TELCOID`                                 
   ) ttable 
#having Sum(smscount) > 2500 ;

STATUS  TELCOID smsCount
send    -3      2
send    -1      2487
send    158     233
send    162     16

我需要的是添加一个where / having子句，它将检查sum（smscount）＆gt; 2500然后返回结果集其他明智的没有我可以在此查询中更改什么来实现它。在当前结果中，2 + 2487 + 233 + 16的总和大于2500，因此它不会返回任何东西。如果不是2500我将3000放置，那么结果集将返回

您需要运行两个查询或使用变量。我认为这可能有用：

SELECT status, telcoid, smscount
FROM  (SELECT `STATUS`, `TELCOID`, COUNT(*) as smsCount,
              (@s := @s + COUNT(*)) as cumesum              
        FROM `smsout` CROSS JOIN (SELECT @s := 0) vars
        WHERE `STATUS`  = 'Send' AND       
              RECEIVEDTIME BETWEEN DATE_SUB(NOW(), INTERVAL 1000000 MINUTEAND NOW())
        GROUP BY `STATUS` , `TELCOID`                                 
     ) ttable 
WHERE @s > 2500;

有时变量在聚合方面不能正常工作，因此您可能需要额外的子查询层来实现此目的。

编辑：

试试这个版本：

SELECT status, telcoid, smscount
FROM  (SELECT t.*, (@s := @s + COUNT(*)) as cumesum              
       FROM (SELECT `STATUS`, `TELCOID`, COUNT(*) as smsCount
              FROM `smsout`
              WHERE `STATUS`  = 'Send' AND       
                    RECEIVEDTIME BETWEEN DATE_SUB(NOW(), INTERVAL 1000000 MINUTEAND NOW())
              GROUP BY `STATUS` , `TELCOID`                                 
            ) t CROSS JOIN
            (SELECT @s := 0) vars
       ) t
WHERE @s > 2500;

Answer 2

smscount是一个总和，因为你写了count（*）smscount

你可以尝试

吗？

SELECT ttable.* 
FROM  ( SELECT 
        `STATUS`, 
        `TELCOID`,                
        COUNT(*) smsCount                 
        FROM `smsout` 
        WHERE `STATUS`  = 'Send'        
            AND (RECEIVEDTIME BETWEEN DATE_SUB(NOW(), INTERVAL 1000000     MINUTE) AND NOW())
        GROUP BY  `STATUS` , `TELCOID`                                 
   ) ttable 
having smscount > 2500 ;

Answer 3

SELECT `STATUS`, `TELCOID`, COUNT(*) smsCount
FROM `smsout` 
WHERE `STATUS`  = 'Send'        
AND (RECEIVEDTIME BETWEEN DATE_SUB(NOW(), INTERVAL 1000000 MINUTE) AND NOW())
GROUP BY  `STATUS` , `TELCOID` 
HAVING COUNT(*) > 2500;

子查询不是必需的。

mysql有计数总和的子句
