我的初始查询:
select TBL1.REFERENCE, DATE(TBL1.DATETIME), TBL1.AMOUNT, TBL1.DATETIME, TBL1.SENDER, TBL1.RECIPIENT
from SOURCETABLE AS TBL1
WHERE (TBL1.DATETIME >= '2015-05-01 00:00:00' and TBL1.DATETIME <= '2016-07-25 23:59:59' )
GROUP BY DATE(TBL1.DATETIME), TBL1.AMOUNT,TBL1.DATETIME,TBL1.SENDER, TBL1.RECIPIENT
HAVING SUM(TBL1.AMOUNT) > 2000;
--- 0 个结果 ---
但它不起作用。希望有人能告诉我如何解决这个问题。
【问题讨论】:
【参考方案1】:这是一种方法:
select t.*
from sourcetable t
where sender in (select t2.sender
from sourcetable t2
where t2.datetime >= '2015-05-01' and t2.datetime <= '2016-07-26'
group by t2.sender
having sum(t2.amount) > 2000
) and
t.datetime >= '2015-05-01' and t.datetime <= '2016-07-26';
子查询生成符合条件的发件人列表。然后外部查询选择行。

【参考方案2】:替代方法:它将结合两个预期结果
SELECT T1.* FROM <Table> T1 INNER JOIN (
SELECT Sender FROM <table> T GROUP BY Sender HAVING SUM(Amount) > 2000) AS T2 ON T1.Sender = T2.Sender ORDER BY T1.Sender
UNION
SELECT T3.* FROM <Table> T3 INNER JOIN (
SELECT Sender FROM <table> T GROUP BY Sender HAVING SUM(Amount) < 2000) AS T4 ON T3.Sender = T4.Sender ORDER BY T3.Sender
