Question

主要问题是在Start Balance = 0之后选择行。
这是我的代码：

 Select distinct 
    st.date as [Date Incurred],
    ss.brkr_id as [Broker ID],
    ss.period_id as [Period ID],
    case when ss.debt_typ = 'Starting Balance' then sum(st.money_amt) else 0 end as [Starting Balance]
    case when ss.debt_typ = 'Balance' then sum(st.money_amt) else 0 end as [Balance]
    case when ss.debt_typ = 'End Balance' then sum(st.money_amt) else 0 end as [End Balance]
    into #temp1
    from debt_t st
    inner join debt_info ss
    on ss.period_id = st.period_id
    where brkr_id = '754234'
    and st.money_amt >0.00
    group by 
    st.date as [Date Incurred],
    ss.brkr_id as [Broker ID],
    ss.period_id as [Period ID]

select Date_Incurred,
Broker_ID,
Period_ID
max(Starting_Balance) as [Start Balance]
max(Balance) as [Current Balance]
max(End Balance) as [End Balance]
from #Temp1
group by 
Date_Incurred,
Broker_ID,
Period_ID

这会带回这个结果集，让我更接近我想要的但不完全是我想表达的。这显示了此Broker的所有历史记录我只想显示最新Start Balance为0.00时的信息。所以一旦结束债务已经支付，例如0.00我不想看到这一点。我只想看到公开债务。从最新的起始余额0.00到今天。

以下是结果集我希望在最新的起始余额0.00到今天之间返回所有信息。

Answer 1

除非我错误地阅读您的问题，否则您应该只需添加一个WHERE条款，该条款限制所发生的日期大于或等于起始余额显示为零的日期。请注意，在下面的查询中，我在子查询中使用TOP 1作为预防措施，如果多个记录的起始余额为零。在这种情况下，您可能需要为我们提供额外的逻辑来处理它。

SELECT Date_Incurred,
       Broker_ID,
       Period_ID,
       MAX(Starting_Balance) AS [Start Balance],
       MAX(Balance) AS [Current Balance],
       MAX(End Balance) AS [End Balance]
FROM #Temp1
WHERE Date_Incurred >= (SELECT TOP 1 Date_Incurred FROM #Temp1
                        GROUP BY Date_Incurred, Broker_ID, Period_ID
                        HAVING MAX(Starting_Balance) = 0
                        ORDER BY Date_Incurred DESC)
GROUP BY Date_Incurred,
         Broker_ID,
         Period_ID

Answer 2

我的建议是在临时表中添加属于行号的列您可以选择包含Start Balance等于零的行数，然后选择大于此行的rows。

-- Define #temp1 tabel 
 IF OBJECT_ID('tempdb..#temp1') IS NOT NULL
    DROP TABLE #temp1

create table #temp1 
(
    ID int IDENTITY(1,1) PRIMARY KEY,--colum belong to row number
    DateIncurred int,
    PeriodID int,
    StartingBalance varchar (200),
    Balance varchar (200),
    EndBalance varchar (200)
)

INSERT INTO #temp1 (DateIncurred, PeriodID, StartingBalance, Balance, EndBalance)

 Select distinct 
    st.date as [Date Incurred],
    ss.brkr_id as [Broker ID],
    ss.period_id as [Period ID],
    case when ss.debt_typ = 'Starting Balance' then sum(st.money_amt) else 0 end as [Starting Balance]
    case when ss.debt_typ = 'Balance' then sum(st.money_amt) else 0 end as [Balance]
    case when ss.debt_typ = 'End Balance' then sum(st.money_amt) else 0 end as [End Balance]
    --into #temp1
    from debt_t st
    inner join debt_info ss
    on ss.period_id = st.period_id
    where brkr_id = '754234'
    and st.money_amt >0.00
    group by 
    st.date as [Date Incurred],
    ss.brkr_id as [Broker ID],
    ss.period_id as [Period ID]

这里选择行数等于零。

select 
ROW_NUMBER() OVER(ORDER BY ID ASC) AS [Row number]
Date_Incurred,
Broker_ID,
Period_ID
max(Starting_Balance) as [Start Balance]
max(Balance) as [Current Balance]
max(End Balance) as [End Balance]
from #Temp1
where max(Starting_Balance) = 0
group by 
Date_Incurred,
Broker_ID,
Period_ID

您可以选择大于该行的行。

选择具有特定值的行后的数据
