Как добавить значение компонента без повторяющегося ItemId в сводную таблицу?
Я работаю на SQL server 2012.
Я создаю сводную таблицу на основе itemId, но при добавлении данных Featurevalue повторяется
так, как предотвратить повторение ItemId?
желаемый результат
ItemCode IPN PartnerName CustomerName Fan Refrigator temprature FeatureValue
1 1233 Saico Michel 1 2 1 1234
2 5433 Mbaby Michel 0 1 0 7777
3 44333 sadeoMany Michel 1 0 1 88888
Что я пробовал:
create table #InputData
(
CustomerID uniqueidentifier
)
insert into #InputData values ('0ce19920-f0ca-433c-abb1-4e84d52b618b'),('188b8053-18c0-4092-955e-962f54485e43')
create table #customers
(
CustomerID uniqueidentifier,
CustomerName nvarchar(200)
)
insert into #customers
values
('0ce19920-f0ca-433c-abb1-4e84d52b618b','Michel')
create table #FeatureType
(
FeatureId int,
FeatureName nvarchar(200)
)
insert into #FeatureType
values
(1,'temprature'),
(2,'Fan'),
(3,'Refrigator')
create table #Items
(
ItemId int,
IPN nvarchar(200),
PartnerPart nvarchar(200),
PartnerName nvarchar(100)
)
insert into #Items
values
(1,'1233','Mobilic','Saico'),
(2,'5433','Saldom','Mbaby'),
(3,'44333','Silicon','sadeoMany')
create table #ItemFeatures
(
ItemFeatureId int,
ItemId int,
FeatureId int,
CustomerId uniqueidentifier,

insert into #ItemFeatures

DECLARE @Columns as VARCHAR(MAX)

ORDER BY B.FeatureName
DECLARE @SQLs as VARCHAR(MAX)
