先建立一個數據表 StudentTable

CREATE TABLE StudentTable(
 [Id] [int] IDENTITY(1,1) NOT NULL,
 [UserName] [nvarchar](50) NULL,
 [Subname] [nvarchar](50) NULL,
 [Source] [numeric](18, 0) NULL
) ON [PRIMARY]
go
 INSERT INTO StudentTable ([UserName],[Subname],[Source]) 
 SELECT N'張三',N'語文',65 UNION ALL
 SELECT N'
 
李四',N'數學',75 UNION ALL
 SELECT N'王五',N'英語',80 UNION ALL
 SELECT N'王五',N'數學',78 UNION ALL
 SELECT N'王五',N'語文',48 UNION ALL
 SELECT N'李四',N'語文',82 UNION ALL
 SELECT N'張三',N'英語',100
GO

然後建立一個儲存過程，對資料進行轉換

alter proc pro_test
as

  declare @subjName  varchar(50);
  declare @sql varchar(2000);

  select id,[
 
UserName],[Subname],[Source] into #objTab from TestTable ;
  select DIstinct UserName  into #studentTab from #objTab;
    set @subjName='';
    Declare  chimayoubiao  Cursor for select distinct Subname from  #objTab  for read only;
    open chimayoubiao
    fetch next from  chimayoubiao into @subjName
 
;

    while @@FETCH_STATUS =0 
    begin
       set @sql='alter table #studentTab add '+ @subjName +' varchar(50) default(0);';
       exec(@sql);
       print @sql;
       set @sql='update #studentTab set '+@subjName+'= Q.Source 
       from #studentTab C join #objTab Q on c.UserName=Q.UserName
       and '''+@subjName+''' = Q.Subname';
       Exec(@sql);
       print @sql;
       set @sql=' update #studentTab set '+ @subjName +'=0 where '+ @subjName +' is null';
       Exec(@sql);
       fetch next from chimayoubiao into @subjName;
    end;


select * from #studentTab;
close chimayoubiao;
deallocate chimayoubiao

drop table #studentTab;
drop table #objTab;

go

使用pivot 進行轉換

select * from(select UserName,Subname,Source from TestTable) test
 pivot(sum(Source) for Subname in(語文,數學,英語)) pvt
