总是学会在关系数据库中使用union而不是or。试试看工会能否解决你的问题。

select cols
from table
where statement1 AND statement2 AND statement3

union all

select cols
from table
where statement1 AND statement2 AND statement4

count是真正的变量名吗？再检查一遍。
还要检查时间是否是数字类型，可能是bigint。如果不是像这样把它转换成一个大整数：

WHERE cast(time as bigint) >= 1435536000 AND cast(time as bigint) < 1436140800

尝试将or语句更改为in语句。

SELECT 
 cid,
 SUM(count) AS total_count
FROM
count_by_day
WHERE time >= 1435536000 AND time < 1436140800
AND cid in('4eb3441f282d4d657a000016','14ebe153121a863462300043d')
GROUP BY
cid;

每次尝试一个更改，这样您就知道修复方法是什么。

查询1：

Select A,B,C
From 
                Table1 t1
                Join 
                Table2 t2
                On 
                                T1.field1=T2.field1 OR 
                                T1.field2 = T2.field2

查询2：

Select A,B,C
From 
                Table1 t1
                Join 
                Table2 t2
                On 
                                T1.field1=T2.field1 

Union 

Select A,B,C
From 
                Table1 t1
                Join 
                Table2 t2
                On 
                                T1.field2 = T2.field2
