Question

假设我们有日记帐分录表如下

create table jour_entries 
 (jseq number, 
  j_date date, 
  Eseq number, 
  account_no varchar2(32), 
  debit number, 
  credit number,
  note varchar2(256) );

如何在SQL中为试算平衡建立最佳性能报告？报告列是

account_number：是帐号。
debit_within_month：与account_number相关的所有借方的总和，从给定月份的第1个月到该月末（如果给定日期是当月，则直到当天）
credit_within_month：与account_number相关的所有信用额的总和，从给定月份的第1个月到该月末（或者当前日期，如果给定日期是当前月份）
debit_till_this_day：是指给定日期年份（从给定日期的1月1日到当天）与account_number相关的所有借方的累计金额。
credit_till_this_day：是指给定日期年份（从给定日期的1月1日到当天）与account_number相关的所有信用的累计金额。

我尝试了这个选择：

select account_number
      , debit_within_month
      , credit_within_month
      , debit_till_this_day
      , credit_till_this_day
from jour_entries j, 
    (select account_number, sum(debit) debit_within_month, 
                         sum(credit) credit_within_month
              from jour_entries 
              where j_date between trunc(given_date, 'month') and given_date
              group by account_number
    ) j1,
    (select account_number, sum(debit) debit_till_this_day,
                         sum(credit) credit_till_this_day  
              from jour_entries 
              where j_date between trunc(given_date, 'year') and given_date
              group by account_number
    ) j2
wherer j.account_number = j1.account_number
and j.account_number = j2.account_number

但我正在寻找其他解决方案（可能通过使用分析函数）以获得最佳性能。

我将使用SQL * Plus替换变量语法来指示given_month。对于您实际使用的客户，您需要更改此内容。

select account_number
       , sum ( case when J_date between trunc(&given_date, 'mm') 
                                    and least(sysdate, last_day(&given_date)) 
          then debit else 0 end ) as debit_within_month
       , sum ( case when J_date between trunc(&given_date, 'mm')
                                   and least(sysdate, last_day(&given_date)) 
            then credit else 0 end ) as credit_within_month
       , sum ( case when J_date between trunc(&given_date, 'yyyy') and sysdate)  
               then debit else 0 end ) as debit_til_this_day
      , sum ( case when J_date between trunc(&given_date, 'yyyy') and sysdate)  
              then credit else 0 end ) as credit_til_this_day
from jour_entries
group by account_number

<强>解释

trunc()会将其截断为给定的格式掩码。所以trunc(sysdate, 'mm')给出了本月的第一天，并且＆＃39; yyyy＆＃39;面具给了一年的第一个。
last_day()给出了呃，给定月份的最后一天。

如果我理解你的问题，听起来像这样的事情对你有用：

SELECT JE.Account_no as Account__Number,
    SUM(JE2.debit) as Debit_Within_Month,
    SUM(JE2.credit) as Credit_Within_Month,
    SUM(JE.debit) as Debit_Till_This_Day,
    SUM(JE.credit) as Credit_Till_This_Day
FROM Jour_Entries JE
    LEFT JOIN (
        SELECT jseq, Account_No, Debit, Credit
        FROM Jour_Entries
        WHERE to_char(j_date, 'YYYY') = 2013 AND to_char(j_date, 'mm') = 2
    ) JE2 ON JE.jseq  = JE2.jseq 
WHERE to_char(j_date, 'YYYY') = 2013 
GROUP BY JE.Account_no

这是sql fiddle。

祝你好运。
