我有下表
PnlId LineTotalisationId Designation Totalisation
1 A Gross Fees Formule A01+A02+A03+A04+A05
2 A01 GF1 Comptes B01+B02+B03+B04+B05
3 A02 GF2 Comptes C01+C02+C03+C04+C05
4 A03 GF3 Comptes 99991
5 A04 GF4 Comptes 99996
6 A05 GF5 Comptes 999995
14 B1 Perm Comptes 12+14+25
我希望得到
如果Designation =总计中的Formule LineTotalisationId为PnlId内容编号的名称，那么我应该为所有Totalisation汇总Totalisation，否则我只需添加行
我尝试以下代码
SELECT Ref.*,
CASE
WHEN Charindex('+', Ref.totalisation) > 0 THEN '+'
WHEN Charindex('/', Ref.totalisation) > 0 THEN '/'
WHEN Charindex('*', Ref.totalisation) > 0 THEN '*'
WHEN Charindex('*', Ref.totalisation) > 0 THEN '-'
END AS Operator
INTO ##ttresults
FROM [dbo].[pnlreference] Ref
WHERE [typetotalisation] = 'Formule'
AND totalisation <> ''
AND designation NOT LIKE '%[0-9]%'
AND designation != ''
SELECT split.linetotalisationid AS PNLParentId,
NULL AS Totalisation
INTO ##tempresults
FROM (SELECT tbl.designation,
tbl.linetotalisationid,
tbl.typetotalisation,
tbl.pnlid,
tbl.totalisation,
Cast('<t>'
+ Replace(tbl.totalisation, tbl.operator, '</t><t>')
+ '</t>' AS XML) x,
tbl.operator
FROM ##ttresults AS tbl) split
CROSS apply x.nodes('/t') t(c)
INNER JOIN [dbo].[pnlreference] Ref
ON Ref.linetotalisationid = t.c.value('.', 'nvarchar(255)')
WHERE Ref.designation LIKE '%[0-9]%'
OR Ref.designation = ''
GROUP BY split.linetotalisationid ;
上面的代码作为结果返回
PNLParentId
A
有没有办法修改它以获得描述的总计？

如果您的示例数据代表您的数据，您可以尝试下面的sql
假设Panel是您的表名，Line字段只有1个字符串
Declare @sql nvarchar(max);
;
set @sql =
'with cte as

case
when patindex(''%[A-Z]%'',Line) > 0
then
substring(line,patindex(''%[A-Z]%'',Line),1)
end as LineId

from panel
where line in (' +''''+ (select replace(a.totalisation,'+',''',''') from Panel a where Designation='formule' ) + '''' +')
union all
select
Line as LineId,
Totalisation
from panel
where line not in (' +''''+ (select replace(a.totalisation,'+',''',''') from Panel a where Designation='formule' ) + '''' +')
and Designation <> ''Formule''

此存储过程可作为您的问题的解决方案。它正在使用游标。可能有一种方法可以删除光标，但直到现在才能使用。所以得到了这个解决方案。
CREATE Procedure [dbo].[spGetResult]
As
Begin
declare @curPNL cursor
declare @pnlid int
declare @Line varchar(10), @TotalisationId varchar(20), @Totalisation varchar(50)
declare @spresult table(PNLId int, Line varchar(10), TotalisationId varchar(20), result varchar(4000));
--declare the cursor
set @curPNL = cursor
for select PnlId, Line, TotalisationId, totalisation
from PNLTable where designation = 'Formule'
open @curPNL
Fetch Next From @curPNL into @pnlId, @Line, @TotalisationId, @Totalisation
While @@FETCH_STATUS = 0
Begin
declare @nsql nvarchar(4000);
declare @table table(tname varchar(50));

delete from @table
--get the totalisation data for specific column
set @nsql = 'select totalisation from PNLTable Where Line in (''' + replace(@Totalisation,'+',''',''') + ''')';
print 'Calling child'
insert into @table
exec(@nsql);
set @result = '';
if not exists (select 1 from @table)
Begin

虽然桌面结构对我来说不太清楚。但我使用以下脚本来创建表并插入数据。
CREATE TABLE [dbo].[PNLTable](
[PnlId] [int] NOT NULL,
[Line] [varchar](10) NULL,
[TotalisationId] [varchar](20) NULL,
[Designation] [varchar](20) NULL,
[Totalisation] [varchar](50) NULL,
PRIMARY KEY CLUSTERED
(
[PnlId] ASC
)
)
- 插入数据
INSERT [PNLTable]
([PnlId], [Line], [TotalisationId], [Designation], [Totalisation])
VALUES (1, N'A', N'Gross Fees', N'Formule', N'A01+A02+A03+A04+A05'), (2, N'A01', N'GF1', N'Comptes', N'99999')
,(3, N'A02', N'GF2', N'Comptes', N'99998'), (4, N'A03', N'GF3', N'Comptes', N'99991'), (5, N'A04', N'GF4', N'Comptes', N'99996')
, (6, N'A05', N'GF5', N'Comptes', N'999995'), (14, N'B1', N'Perm', N'Formule', N'12+14+25')

您必须使用Designation=Formule中的公式生成动态sql查询，而不是使用大型静态查询。然后使用EXEC运行代码。
查询可能是这样的：
SELECT
(SELECT Totalisation WHERE Line = 'A01')
+
(SELECT Totalisation WHERE Line = 'A02')
+
(SELECT Totalisation WHERE Line = 'A03')
+
(SELECT Totalisation WHERE Line = 'A04')
+
(SELECT Totalisation WHERE Line = 'A05')
FROM [dbo].[pnlreference] AS Ref
WHERE Designation = 'Formule'
AND LEFT(Line, 1) = 'A'
可能将公式内容拆分为单个条目和运算符，并将其加载到包含公式（perhabs A01和A02等）和id的临时表中。 然后生成代码：代码可能是这样的：
EXEC 'SELECT
(SELECT Totalisation WHERE Line = ' + CAST((SELECT Formular FROM #formular WHERE id = 0) AS VARCHAR(MAX)) +')
' + CAST((SELECT Operator FROM #formular WHERE id = 1) AS VARCHAR(MAX)) +'
(SELECT Totalisation WHERE Line = ' + CAST((SELECT Formular FROM #formular WHERE id = 1) AS VARCHAR(MAX)) +')
' + CAST((SELECT Operator FROM #formular WHERE id = 2) AS VARCHAR(MAX)) +'
(SELECT Totalisation WHERE Line = ' + CAST((SELECT Formular FROM #formular WHERE id = 2) AS VARCHAR(MAX)) +')
' + CAST((SELECT Operator FROM #formular WHERE id = 3) AS VARCHAR(MAX)) +'
(SELECT Totalisation WHERE Line = ' + CAST((SELECT Formular FROM #formular WHERE id = 3) AS VARCHAR(MAX)) +')
' + CAST((SELECT Operator FROM #formular WHERE id = 4) AS VARCHAR(MAX)) +'
(SELECT Totalisation WHERE Line = ' + CAST((SELECT Formular FROM #formular WHERE id = 4) AS VARCHAR(MAX)) +')
FROM [dbo].[pnlreference] AS Ref
WHERE Designation = ''Formule''
AND LEFT(Line, 1) = ' + LEFT(CAST((SELECT Formular FROM #formular WHERE id = 0) AS VARCHAR(MAX)), 1);
