行转列。Value值为String类型,如果合并

SQL code


select distinct tp.[order],tp.Module,
(case tpt.Name when 'Color' then Value else '' end) Color,
(case tpt.Name when 'Total' then Value else '' end) Total,
(case tpt.Name when 'DeliveryDate' then Value else '' end) DeliveryDate 
from UserDataModel.T_LeanLinePlan tp left join
UserDataModel.T_LeanLinePlanAttribute tpt
on tp.LeanLinePlanId=tpt.LeanLinePlanId




value值为‘’,所有数据集出现很多空白的

SQL code

select tp.[order],tp.Module,
Max(case tpt.Name when 'Color' then Value else '' end) Color,
Max(case tpt.Name when 'Total' then Value else '' end) Total,
Max(case tpt.Name when 'DeliveryDate' then Value else '' end) DeliveryDate 
from UserDataModel.T_LeanLinePlan tp left join
UserDataModel.T_LeanLinePlanAttribute tpt
on tp.LeanLinePlanId=tpt.LeanLinePlanId
Where Name in('Color','Total','DeliveryDate')
Group by tp.[order],tp.Module
