Question

我有以下数据：

with source (Account,AccountNumber,Indentation) as
(
select 'INCOME STATEMENT',1000,0 union all
select 'REVENUE',1100,0 union all
select 'Revenue - Aircon',1110,1 union all
select 'Revenue - Consumer Goods',1120,1 union all
select 'Revenue - Spares',1130,1 union all
select 'Revenue - Accessories',1140,1 union all
select 'Revenue - Sub Stock',1150,1 union all
select 'Revenue - Services',1160,1 union all
select 'Revenue - Other',1170,1 union all
select 'Revenue - Intercompany',1180,1 union all
select 'Revenue - Delivery Charges',1400,1 union all
select 'COST OF SALES',1500,0 union all
select 'COGS - Aircon',1510,1 union all
select 'COGS - Consumer Goods',1520,1 union all
select 'COGS - Spares',1530,1 union all
select 'COGS - Accessories',1540,1 union all
select 'COGS - Sub Stock',1550,1 union all
select 'COGS - Services',1560,1 union all
select 'COGS - Other',1570,1 union all
select 'COGS - Intercompany',1580,1 union all
select 'COS - Sub Stock Stock Adjustments',1610,1 union all
select 'COS - Sub Stock Repairs',1620,1 union all
select 'COS - Consumables & Packing Materials',1810,1 union all
select 'COS - Freight & Delivery',1820,1 union all
select 'COS - Inventory Adj - Stock Count',1910,1 union all
select 'COS - Inv. Adj - Stock Write up / Write down',1920,1 union all
select 'COS - Provision for Obsolete Stock (IS)',1930,1 union all
select 'COS - Inventory Adj - System A/c',1996,1 union all
select 'COS - Purch & Dir. Cost Appl A/c - System A/c',1997,1 union all
select 'GROSS MARGIN',1999,0 union all
select 'OTHER INCOME',2000,0 union all
select 'Admin Fees Received',2100,1 union all
select 'Bad Debt Recovered',2110,1 union all
select 'Discount Received',2120,1 union all
select 'Dividends Received',2130,1 union all
select 'Fixed Assets - NBV on Disposal',2140,1 union all
select 'Fixed Assets - Proceeds on Disposal',2145,1 union all
select 'Rebates Received',2150,1 union all
select 'Rental Income',2160,1 union all
select 'Sundry Income',2170,1 union all
select 'Warranty Income',2180,1 union all
select 'INTEREST RECEIVED',2200,0 union all
select 'Interest Received - Banks',2210,1
)

select
    Account
,   AccountNumber
,   Indentation
from    source;

使用以下脚本：

with s as (
select
    iif(Account like 'Total%',null,iif(Indentation=0,Account,null)) Header
,   iif(Account like 'Total%',null,iif(Indentation=1,Account,null)) SubHeader1
,   *
from    Source
)

select
    Header
--, case lag(Header) over (order by [Account Number]) when Header then isnull(Header,lag(Header) over (order by [Account Number])) else Header end
,   SubHeader1
,   [Account Number]
,   Indentation
from    s

我可以这样拆分列：

我需要能够报告 Header 列如下所示：

我尝试使用 LAG() 执行此操作，但它不起作用，我该如何编写脚本？

Answer 1

这是一个选项。我为每个 header 创建了一个组，然后用它来获取该组中缩进 = 0 的第一个组。将其添加到您的源 CTE 中：

,CTE2 AS
(
select
    iif(Account like 'Total%',null,iif(Indentation=0,Account,null)) Header
,   iif(Account like 'Total%',null,iif(Indentation=1,Account,null)) SubHeader1
, SUM(CASE WHEN Indentation = 0 THEN 1 ELSE 0 END) OVER (ORDER BY AccountNUmber) H1
,   *
from    Source
)

SELECT T2.Header, t1.SubHeader1, t1.AccountNumber, t1.Indentation
FROM CTE2 t1
CROSS APPLY(SELECT MAX(t3.HEADER) HEADER FROM CTE2 T3 where t3.H1 = T1.H1 and T3.Indentation = 0 ) T2
ORDER BY t1.AccountNumber
