Question

I work on SQL server 2012 when Build dynamic Query I get error

 

Msg 8114, Level 16, State 5, Line 16 Error converting data type varchar to float.

 

so How to solve this Error ?

 

I build dynamic query based on @Header and @column and @Body .

 

@Header represent header must display as Headers .

@column represent pivot columns .

@Body represent select query for data .

create table #FinalTable
(
PART_ID nvarchar(50) ,
CompanyName nvarchar(50),
PartNumber nvarchar(50),
DKFeatureName nvarchar(100),
value float,
StatusId int,
DisplayOrder int,
splitFlag bit
)
insert into #FinalTable
