Question

任何人都可以告诉我如何显示两行值，一行两列不同的列值和两列。以下是表格：

Test ID     Total Employees    Response Score     Eval Score
1                7                    4.24              0
1                7                       0              4.78
2                13                   4.52              0
2                13                      0              4.89

所以我正在寻找输出：

Test ID     Total Employees    Response Score     Eval Score
1                7                    4.24             4.78
2                13                   4.52             4.89

Answer 1

select [Test ID], 
       [Total Employees], 
       max([Response Score]) as [Response Score],
       max([Eval Score]) as [Eval Score]
from your_table
group by [Test ID], [Total Employees]

Answer 2

您可以使用带有GROUP BY的聚合函数来获得结果：

select TestId, 
   totalEmployees, 
   max(ResponseScore) responseScore, 
   max(EvalScore) EvalScore
from yourTable
group by TestId, totalEmployees;

两行值合二为一
