使用双重嵌套 sql 查询 sybase 选择特定卡片

Question

SELECT card_num, 
       COUNT(merchant_code) 
from e_transaction 
where trans_date between '20161017 00:00' and '20161017 23:59' 
and channelid='02' 
and trans_code='P' 
and card_num in (select card_num, 
                        sum(trans_amount) 
                 from e_transaction 
                 where trans_date between '20161017 00:00' and '20161017 23:59' 
                 and channelid='02' 
                 and trans_code='T' 
                 and card_num not in (select card_num 
                                      from e_transaction 
                                      where trans_date between '20160724 00:00' and '20161016 23:59') 
                 group by card_num 
                 having sum(trans_amount) > 100000) 
group by card_num 
having count (merchant_code) > 1

我一直收到此查询的语法错误，但似乎无法找到错误所在。我试图在今天使用相同的 merchant_code 假脱机多个 card_num，trans_amount 大于 100000，并且在 20160724 和昨天

之间找不到

正确格式化查询后，很容易发现问题。在您的第一个嵌套 select 中，您写道：

and card_num in (select card_num, 
                        sum(trans_amount) 
                 from e_transaction 
                 ...)

in 需要单列，但您的嵌套 select 给出了两列。您需要做的就是从嵌套的 select 中删除 sum(trans_amount)，如下所示：

and card_num in (select card_num
                 from e_transaction 
                 ...)
