SQLで行から列にデータを再編成

Question

私はuniプロジェクトにおり、これに固執しています。私は以下のデータを持っており、2番目の表のように変更して見たいと思っています。 SQLでこれを実行することは可能ですか？動的なものにすることはできますか？誰からの提案ですか？

サンプルデータ：

Answer 1

これは（SQL Serverを仮定して）行います：

if OBJECT_ID('tempdb..#tmp') is not null 
    drop table #tmp; 

create table #tmp 
(
    tmp_sid int not null identity(1,1), 
    dbk varchar(80), 
    item varchar(80), 
    dpi varchar(80), 
    dvb varchar(80), 
    name varchar(80) 
); 

insert into #tmp values('816408','Air','9882067','383311','Virgin Australia'); 
insert into #tmp values('816432','Other','7205311','376023','House of Travel Ltd'); 
insert into #tmp values('816432','Other','7205312','376023','House of Travel Ltd'); 
insert into #tmp values('816432','Other','7205312','376023','House of Travel Ltd'); 
insert into #tmp values('816553','Hotel','10205063','387077','Mantra On Salt Beach'); 
insert into #tmp values('816553','Ins','10205064','377326','Allianz Global Assistance'); 
insert into #tmp values('816553','Ins','10205065','377326','Allianz Global Assistance'); 
insert into #tmp values('816553','Fee','10205069','0','Unknown'); 

declare @q varchar(max); 

select 
    @q = coalesce(@q + ',', '') + QUOTENAME(item) 
from 
    #tmp 
group by 
    item; 

set @q = 'select dbk,' + @q + 'from #tmp pivot (max(item) for item in (' + @q + ')) U' 

exec (@q);
