CSV to Multiple Columns

If the table is denormalised and has Comma Seperate Values in a column, this code will copy it to Multiple columns of a Normalised table





declare @DeNormalisedTable table(data varchar(8000))

insert into @DeNormalisedTable
select '1,Davolio,Nancy' union all
select '2,Fuller,Andrew' union all
select '3,Leverling,Janet' union all
select '4,Peacock,Margaret' union all
select '5,Buchanan,Steven' union all
select '6,Suyama,Michael' union all
select '7,King,Robert' union all
select '8,Callahan,Laura' union all
select '9,Dodsworth,Anne'

select * from @DeNormalisedTable -- Comma Seperated Values

declare @s varchar(8000), @data varchar(8000)
Create table #NormalisedTable (Code int, FirstName varchar(100), LastName varchar(100))

select @s=''

while exists (Select * from @DeNormalisedTable where data>@s)
Begin
Select @s=min(data) from @DeNormalisedTable where data>@s
select @data=''''+replace(@s,',',''',''')+''''
insert into #NormalisedTable
exec('select '+@data)
End

select * from #NormalisedTable -- Data in Normalised Table
