在没有动态查询或相交的情况下提取表中的公共数据

Question

我有以下Vehicle表：

我希望车辆ID /名称包含每个Index值，即以下结果

我做了一个动态查询，可以产生这个结果：

select vehicleId,vehicleName from Vehicle where [Index] = 1
intersect
select vehicleId,vehicleName from Vehicle where [Index] = 2
intersect
select vehicleId,vehicleName from Vehicle where [Index] = 3

但我无法使用包含所有Index值的动态查询。

我需要一个涉及自联接或一些非动态SQL技术的解决方案来执行相同的操作。有可能吗？

Answer 1

使用group by查找每vehicleId, vehicleName个index个组合：

select vehicleId, vehicleName
from Vehicle
group by vehicleId, vehicleName
having count(distinct [index]) = (select count(distinct [Index]) from Vehicle)

Answer 2

CTE可能更清楚了吗？

WITH I_LIST AS (
  SELECT DISTINCT Index
  FROM Vehicle
)
SELECT V.VehicleId, V.VehicleName
FROM I_LIST
LEFT JOIN Vehicle V ON I_List.Index = V.Index
GROUP BY V.VehicleId, V.VehicleName
HAVING COUNT(I_List.Index) = (SELECT COUNT(*) FROM I_LIST)
