SQL查詢通過內部元素

Question

我有一個查詢，列出的特徵，基於組件的狀態和可用性的添加量乘以SUM結果

SELECT Brand.Id 
    , Brand.Name 
    , Brand.Impact 
    , Brand.Visibility 
    , Brand.Risk 
    , SUM(Brand.Impact + Brand.Visibility + Brand.Risk) AS Priority 

FROM Brand 
LEFT OUTER JOIN Type 
    ON Brand.Id = Type.FeatureId 
LEFT OUTER JOIN Model 
    ON Type.Id = Model.SubFeatureId 
LEFT OUTER JOIN TestingStatus 
    ON Model.StatusId = TestingStatus.Id 

WHERE (Model.IsDeleted = 'False') 
    AND (Brand.IsDeleted = 'False') 
    AND (Type.IsDeleted = 'False') 
    AND (@TeamId = 0 OR Model.TeamId = @TeamId) 
GROUP BY Brand.YearId, Brand.Id, Brand.Name, Brand.Impact, Brand.Visibility, Brand.Risk 
HAVING (Brand.YearId = @YearId) 

我的結果如下：

ID Name Impact Visibility Risk Priority 
403 Chevy 1  2   3  48 
404 Nissan 1  1   1  24 
405 Toyota 3  2   1  42 

而不是

ID Name Impact Visibility Risk Priority 
403 Chevy 1  2   3  6 
404 Nissan 1  1   1  3 
405 Toyota 3  2   1  6 

這些品牌中的每一個都分別有8,8和7個型號。這意味着我的查詢正在爲它們計算優先級：Impact*models + Visibility*models + Risk*models。

我怎樣才能讓我的SQL查詢不執行乘法？

感謝

基於您的評論，除非我不理解你需要什麼，我不認爲你需要的SUM()。我想你只是想要每個模型的總數。使用SUM()你會得到所有記錄的總數，它聽起來不像你想要的。這也將刪除您GROUP BY和HAVING

SELECT Brand.Id 
    , Brand.Name 
    , Brand.Impact 
    , Brand.Visibility 
    , Brand.Risk 
    , (Brand.Impact + Brand.Visibility + Brand.Risk) AS Priority 

FROM Brand 
LEFT OUTER JOIN Type 
    ON Brand.Id = Type.FeatureId 
LEFT OUTER JOIN Model 
    ON Type.Id = Model.SubFeatureId 
LEFT OUTER JOIN TestingStatus 
    ON Model.StatusId = TestingStatus.Id 

WHERE (Model.IsDeleted = 'False') 
    AND (Brand.IsDeleted = 'False') 
    AND (Type.IsDeleted = 'False') 
    AND (@TeamId = 0 OR Model.TeamId = @TeamId) 
    AND (Brand.YearId = @YearId)
