mysql - 附加查询参数不起作用

Question

Group By First Query in MySql

所以我提出了上述问题并得到了很好的答复

但是如何在 homematchingid !=0 和 awaymatchingid !=0 中添加？

我已经尝试过以下方法，但都不起作用。

SELECT MIN(`Date`) AS `Date`, MIN(`Time`) AS `Time`,
    `HomeMatchingId`,`AwayMatchingId`,`RunningStatus`
FROM `20121208`
where `HomeMatchingId`!= 0,`AwayMatchingId`!= 0
GROUP BY `HomeMatchingId`,`AwayMatchingId`,`RunningStatus` 
HAVING `RunningStatus`= 1

和

SELECT MIN(`Date`) AS `Date`,MIN(`Time`) AS `Time`,
    `HomeMatchingId`,`AwayMatchingId`,`RunningStatus`
FROM `20121208`
GROUP BY `HomeMatchingId`,`AwayMatchingId`,`RunningStatus` 
HAVING `RunningStatus`=1,`HomeMatchingId`!=0,`AwayMatchingId`!=0);

Answer 1

您需要将 where 子句中的逗号替换为 AND 或 OR 等逻辑运算符。

SELECT MIN(`Date`) AS `Date`, MIN(`Time`) AS `Time`,
`HomeMatchingId`,`AwayMatchingId`,`RunningStatus`
FROM `20121208`
where `HomeMatchingId`!= 0 AND `AwayMatchingId`!= 0
GROUP BY `HomeMatchingId`,`AwayMatchingId`,`RunningStatus` 
HAVING `RunningStatus`= 1
