Sql 当标志“允许1”时，如何将select Query split Temp值构建为两列（每个数字一列，另一列为文本）？

我正在处理SQL Server 2012的查询。我有一个问题：我无法生成选择

当临时表“非参数”中的行具有标志Allow=1时，查询将列临时值拆分为两列

当标志Allow=1时，它必须将列Temp值从非参数拆分为两列

假设列Temp值的值为50.40 kg，则它必须拆分为两列

第一列带有数字，因此它将具有50.40，并且它将与参数化名称相同

第二列包含文本，因此它将具有kg，并且与参数+单位的名称相同

意思是名称将是参数单位

我需要构建一个查询，当Flag Allow=1时，该查询会将其拆分为两列

create table #nonparametricdata
(
PART_ID nvarchar(50) ,
CompanyName  nvarchar(50),
PartNumber nvarchar(50),
DKFeatureName nvarchar(100),
Tempvalue nvarchar(50),
FlagAllow bit
)

insert into #nonparametricdata
values
('1222','Honda','silicon','package','15.50Am',0),
('1900','MERCEIS','GLASS','family','90.00Am',1),--Build select query split data because FlagAllow=1
('5000','TOYOTA','alominia','source','70.20kg',0),
('8000','MACDA','motor','parametric','50.40kg',1),----Build select query split data because FlagAllow=1
('8900','JEB','mirror','noparametric','75.35kg',0)

create table #FinalTable
(
DKFeatureName  nvarchar(50),
DisplayOrder  int
)

insert into #FinalTable (DKFeatureName,DisplayOrder) 
values 
('package',3),
('family',4),
('source',5),
('parametric',2),
('noparametric',1)

我的尝试如下：

   DECLARE @SelectqueryData NVARCHAR(MAX)
   SELECT
   @SelectqueryData = STUFF(
    (
        SELECT ', ' +  case when B.FlagAllow = 1 then '['+A.DKFeatureName+'],['+A.DKFeatureName+'Unit]' else quotename(A.DKFeatureName) end
        FROM #FinalTable A
        join  (Select distinct DKFeatureName,FlagAllow 
   From #nonparametricdata 
 ) B on A.DKFeatureName=B.DKFeatureName

        ORDER BY DisplayOrder
        FOR XML PATH ('')
    ),1,2,''
)
select @SelectqueryData
--select @SelectqueryData from table

预期结果是：

[noparametric], [parametric]--QueryGetNumber,[parametricUnit]--QueryGetUnitOfMeasure
, [package], [family]--QueryGetNumber,[familyUnit]--QueryGetUnitOfMeasure, [source]
