Oracle - 检查日期范围内是否有数据

Question

我有三张桌子（收据，收据，商店）。我有选择，这给了我一个数据，其中包含自宣布日期以来所有商店的所有收据：

select *
from receipts r
join receipt receiptaddinfo ri on r.receiptid=ri.receiptid and r.shop=ri.shop
join shops s on ri.shop=s.shop and shoptype=0
where ri.creationtime >= '2016-05-19 00:00:00' 
order by ri.creationtime desc

桌子商店，包含所有商店，但是，我想检查是否有商店，没有＆＃39;销售/收据＆＃39;自申报日期起。有人可以帮忙吗？

Answer 1

您可以尝试以下SQL语句。

SELECT * from shops s 
WHERE s.shoptype = 0 
AND NOT EXISTS 
(SELECT 1 
 FROM  receipts r,
       receiptaddinfo ri
 WHERE r.receiptid = ri.receiptid 
 AND   r.shop = ri.shop
 AND   ri.shop = s.shop 
 AND   ri.creationtime >= '2016-05-19 00:00:00')
