Vui lòng thử các mã sau. Bạn phải sử dụng truy vấn PIVOT.
create table TableName (Series varchar(20),col2 varchar(10), price decimal(8,2))
insert into TableName values ('105','C50',30)
insert into TableName values ('105','C50',10)
insert into TableName values ('105','C53',20)
insert into TableName values ('105','C53',30)
SELECT Series,
[C50],
[C53]
FROM (SELECT Series,
col2,
price
FROM TableName) AS SourceTable
PIVOT ( SUM(price) FOR col2 IN ([C50],
[C53])
) AS PivotTable;
