如何對sql查詢進行排名

Question

我有一組我想要排名的結果：

我不確定要劃分什麼內容。

查詢：

SELECT DISTINCT 
    TFormSectionID AS FormSectionID, 
    TFSSortOrder AS SectionSortOrder, 
    TSectionItemID AS SectionItemID, TrendType 
FROM    
    Report.TrendData 
WHERE   
    (ProgramID = 1) 
    AND (TrendType > 0) 
    AND tformid = 34 
    AND TFormSectionID = 12 

結果：

FormSectionID SectionSortOrder SectionItemID TrendType 
    12     7     90   1 
    12     7     91   1 
    12     7     154   1 
    12     7     528   1 
    12     9     154   1 
    12     9     528   1 

我想與部分排序順序9的結果被列爲2和部分排序順序7被評爲1

看起來你可以得到你想要的東西DENSE_RANK：

SELECT DISTINCT TFormSectionID AS FormSectionID, 
     TFSSortOrder AS SectionSortOrder, 
     TSectionItemID AS SectionItemID, 
     TrendType, 
     DENSE_RANK() OVER (ORDER BY SectionSortOrder) AS rn  
FROM Report.TrendData 
WHERE (ProgramID = 1) AND (TrendType > 0) AND 
     tformid = 34 and TFormSectionID = 12
