如何将单位显示为同一显示订单的第二个显示项？

Question

我在 SQL 服务器 2012 上工作我遇到问题：我无法将包含单位的功能安排为相同显示顺序的第二项显示。

以特征族为例

'Family' as [Family], 'FamilyMaxValue' as [FamilyMaxValue], 'FamilyUnit' as [FamilyUnit]

我需要如下

'Family' as [Family], 'FamilyUnit' as [FamilyUnit],'FamilyMaxValue' as [FamilyMaxValue]

除我的问题外，每个功能的功能和单位以及最大值都获得相同的 DisplayOrder

如何将单位作为同一显示顺序的第二个显示。

含义变化将是用逗号分隔的项目顺序显示特征单位作为相同显示顺序的第二个显示。

 create table #SplitNumberAndUnitsFinal
(
DKFeatureName  nvarchar(100),
DisplayOrder  int
)
insert into #SplitNumberAndUnitsFinal (DKFeatureName,DisplayOrder)
values
('package',1),
('packageUnit',1),
('Family',2),
('FamilyMaxValue',2),
('FamilyUnit',2),
('parts',3),
('partsMaxValue',3),
('partsUnit',3)
DECLARE @Header nvarchar(max)=( select
substring(
    (
        Select  ', '''+ DKFeatureName +''' as ['+ DKFeatureName +']' AS [text()]
        From #SplitNumberAndUnitsFinal 
        GROUP BY DKFeatureName
        ORDER BY MIN(DisplayOrder)
        --order by DisplayOrder
       
        For XML PATH ('')
    ), 2, 10000) [Columns])
    print @Header

预期结果将特征单元安排为第二个显示：

Feature,FeatureUnit,FeatureMaxValue according to same display Order



'package' as [package], 'packageUnit' as [packageUnit],
'Family' as [Family], 'FamilyUnit' as [FamilyUnit],'FamilyMaxValue' as [FamilyMaxValue],
'parts' as [parts], 'partsUnit' as [partsUnit],'partsMaxValue' as [partsMaxValue]

而且我不需要显示如下：

Feature,FeatureMaxValue,FeatureUnit for same Display Order

'package' as [package], 'packageUnit' as [packageUnit],
 'Family' as [Family], 'FamilyMaxValue' as [FamilyMaxValue], 'FamilyUnit' as [FamilyUnit],
 'parts' as [parts], 'partsMaxValue' as [partsMaxValue], 'partsUnit' as [partsUnit]

如果 DisplayOrder 本身不是唯一的，则您需要一个额外的列来控制显示顺序。这将允许您在 ORDER BY 子句中为所需的顺序指定两列：

CREATE TABLE #SplitNumberAndUnitsFinal
(
    DKFeatureName  nvarchar(100),
    DisplayOrder  int,
    SecondaryDisplayOrder  int
);
INSERT INTO #SplitNumberAndUnitsFinal (DKFeatureName,DisplayOrder,SecondaryDisplayOrder)
VALUES
    ('package',1,1),
    ('packageUnit',1,2),
    ('Family',2,1),
    ('FamilyMaxValue',2,3),
    ('FamilyUnit',2,2),
    ('parts',3,1),
    ('partsMaxValue',3,2),
    ('partsUnit',3,3)
DECLARE @Header nvarchar(MAX)=( select
SUBSTRING(
    (
        SELECT  ', '''+ DKFeatureName +''' as ['+ DKFeatureName +']' AS [text()]
        FROM #SplitNumberAndUnitsFinal 
        ORDER BY DisplayOrder,SecondaryDisplayOrder
        FOR XML PATH ('')
    ), 2, 10000) [Columns]);
PRINT @Header;
