Sql Oracle查询期初和期末余额

您好，我有下表和数据来获取每个账户的期初余额和期末余额。gdate这更像是一个评论，因为它没有回答问题。您的查询简化为：

Select account_no, LAG(closing, 1 ,0) OVER (order by account_no) as opening,
       debit, credit,
       (LAG(closing,1,0) OVER (order by account_no )+ closing) as closing
from (select account_no, 0 as OPEN, SUM(debit) as debit, SUM(credit) as credit,
             sum(debit) - sum(credit) as closing
      FROM ledger
      where gdate > '20-oct-13'
      group by account_no
     ) a;

一些注释<代码>子查询或CTE中的order by没有用处，除非您在下一个外部查询中选择了

rownum

。如果要对结果进行排序，请在外部查询中输入一个

orderby

---

查询本身没有意义。为什么期初余额来自上一个账号？通常，此类术语用于特定账户的日期，并且您已经删除了

group by

条款中的所有日期。

您不断更改您的要求，但根据您目前显示的情况，这是有效的：

select account_no,
 max(opening) keep (dense_rank first order by gdate) as opening,
 sum(debit) as debit,
 sum(credit) as credit,
 max(closing) keep (dense_rank first order by gdate desc) as closing
from (
 select account_no, gdate, credit, debit,
 lag(balance, 1, 0) over (partition by account_no order by gdate) as opening,
 balance as closing
 from (
  select account_no, gdate, debit, credit,
  sum(debit) over (partition by account_no order by gdate) as sum_debit,
  sum(credit) over (partition by account_no order by gdate) as sum_credit,
  sum(credit) over (partition by account_no order by gdate)
   - sum(debit) over (partition by account_no order by gdate) as balance
  from ledger
 )
)
where gdate > date '2013-10-02'
group by account_no
order by account_no;

这与我之前链接的逻辑相同，当你有不同的数据时

我不知道为什么你会显示你的期初余额为正；当你只有借项时，这似乎是错误的。如果这确实是您想要的，那么只需交换余额的计算方式：

...
  sum(debit) over (partition by account_no order by gdate)
   - sum(credit) over (partition by account_no order by gdate) as balance
...

如果您有用于相关表的ddl脚本，这将节省一些人回答此问题的时间，并意味着他们不会猜测数据类型等。我个人认为SQL FIDLE对于共享这类内容非常有用：以下是表结构创建表分类账（账户号varchar2（10）、gdate日期、借方编号（8），信用证号码（8）请你也解释一下结果出了什么问题。你以为会有几排？如果您也有DML a此数据的样本，这将很有帮助。期初和期末余额始终显示0零您希望您发布的样本数据有什么输出？我想你只能得到两行，分别是

10-0001，-4860,05310450

和

30-00011040352,20708

？相同的结果打开和关闭总是显示0zero@user3244687 . . . 如前所述，我没有更改您的查询。我只是评论说这毫无意义。你为什么要从另一个账户中提取余额？

select account_no,
 max(opening) keep (dense_rank first order by gdate) as opening,
 sum(debit) as debit,
 sum(credit) as credit,
 max(closing) keep (dense_rank first order by gdate desc) as closing
from (
 select account_no, gdate, credit, debit,
 lag(balance, 1, 0) over (partition by account_no order by gdate) as opening,
 balance as closing
 from (
  select account_no, gdate, debit, credit,
  sum(debit) over (partition by account_no order by gdate) as sum_debit,
