How to make pivot for features dynamically based on feature name and feature value ?

[ahmedsa2018]

I work on sql server 2019 i can't make pivot for feature values based on feature name .

i need to apply pivot dynamically because may be tomorrow add new features so it will depend on features on table .

for original part id i have 4 features as

ProgramMemoryOriginal,NumberCoresOriginal,NumberADCsOriginal,NumberDACsOriginal

for RecomendationPartId i have 4 features as

ProgramMemoryRecomended,NumberCoresRecomended,NumberADCsRecomended,NumberDACsRecomended

i need to pivot every feature value under every feature name so feature name will display horizontally

if features not exist or remaining for parts as part id 2081978 then it will display as null

code as below

CREATE TABLE #partsrecomendation(
  [OrignalPartId] [int] NOT NULL,
  [RecomendationPartId] [int] NOT NULL
 ) ON [PRIMARY]
    
 GO
 INSERT #partsrecomendation ([OrignalPartId], [RecomendationPartId]) VALUES (20819956,1595758)
 INSERT #partsrecomendation ([OrignalPartId], [RecomendationPartId]) VALUES (20819770,2081978)
    
    
 CREATE TABLE #TechnologyPlPartsFeaturValues(
  [PartID] [int] NOT NULL,
  [FeatureID] [int] NULL,
  [FeatureName] [nvarchar](508) NOT NULL,
  [FeatureValue] [nvarchar](500) NOT NULL
 ) ON [PRIMARY]
    
 GO
    
 INSERT #TechnologyPlPartsFeaturValues ([PartID], [FeatureID], [FeatureName], [FeatureValue]) VALUES (20819956, 1500500021, N'ProgramMemoryOriginal', N'FLASH')
 INSERT #TechnologyPlPartsFeaturValues ([PartID], [FeatureID], [FeatureName], [FeatureValue]) VALUES (20819956, 1500500011, N'NumberCoresOriginal', N'1')
 INSERT #TechnologyPlPartsFeaturValues ([PartID], [FeatureID], [FeatureName], [FeatureValue]) VALUES (20819956, 1500500066, N'NumberADCsOriginal', N'2')
 INSERT #TechnologyPlPartsFeaturValues ([PartID], [FeatureID], [FeatureName], [FeatureValue]) VALUES (20819956, 1500500081, N'NumberDACsOriginal', N'1')
    
    
 INSERT #TechnologyPlPartsFeaturValues ([PartID], [FeatureID], [FeatureName], [FeatureValue]) VALUES (1595758, 1500500021, N'ProgramMemoryRecomended', N'Light')
 INSERT #TechnologyPlPartsFeaturValues ([PartID], [FeatureID], [FeatureName], [FeatureValue]) VALUES (1595758, 1500500011, N'NumberCoresRecomended', N'12')
 INSERT #TechnologyPlPartsFeaturValues ([PartID], [FeatureID], [FeatureName], [FeatureValue]) VALUES (1595758, 1500500066, N'NumberADCsRecomended', N'75')
 INSERT #TechnologyPlPartsFeaturValues ([PartID], [FeatureID], [FeatureName], [FeatureValue]) VALUES (1595758, 1500500081, N'NumberDACsRecomended', N'90')
    
    
    
 INSERT #TechnologyPlPartsFeaturValues ([PartID], [FeatureID], [FeatureName], [FeatureValue]) VALUES (20819770, 1500500021, N'ProgramMemoryOriginal', N'Silicon')
 INSERT #TechnologyPlPartsFeaturValues ([PartID], [FeatureID], [FeatureName], [FeatureValue]) VALUES (20819770, 1500500011, N'NumberCoresOriginal', N'509')
 INSERT #TechnologyPlPartsFeaturValues ([PartID], [FeatureID], [FeatureName], [FeatureValue]) VALUES (20819770, 1500500066, N'NumberADCsOriginal', N'701')
 INSERT #TechnologyPlPartsFeaturValues ([PartID], [FeatureID], [FeatureName], [FeatureValue]) VALUES (20819770, 1500500081, N'NumberDACsOriginal', N'208')
    
    
    
    
    
 INSERT #TechnologyPlPartsFeaturValues ([PartID], [FeatureID], [FeatureName], [FeatureValue]) VALUES (2081978, 1500500021, N'Program Memory TypeRecomended', N'Electricity')
 INSERT #TechnologyPlPartsFeaturValues ([PartID], [FeatureID], [FeatureName], [FeatureValue]) VALUES (2081978, 1500500011, N'NumberCoresRecomended', N'72')
 INSERT #TechnologyPlPartsFeaturValues ([PartID], [FeatureID], [FeatureName], [FeatureValue]) VALUES (2081978, 1500500066, N'NumberADCsRecomended', N'925')

expected result

You need to use a dynamic query to build the list for the pivot. I wrote about that here:
