SQL服务器：从表更新列，如果记录的一个> = X

Question

我需要帮助，在现有的临时表更新我的专栏之一，每次的指标之一是> = 4

下面是我的查询我正在努力：

DECLARE @Met NVARCHAR(MAX) 
SET @Met = 'MET' 

DECLARE @NotMet NVARCHAR(MAX) 
SET @NotMet = 'NOT MET' 

UPDATE #TmpTbl 
SET Score_Oct = (CASE 
        WHEN ([Type] LIKE '%Metric%') AND CAST(Score_Oct AS INT) >= 4 
         THEN @NotMet 
         ELSE @Met 
       END), 
    Score_Nov = (CASE 
        WHEN ([Type] LIKE '%Metric%') AND CAST(Score_Nov AS INT) IN (4, 5, 6) 
         THEN @NotMet 
         ELSE @Met 
       END), 
    Score_Dec = (CASE 
        WHEN ([Type] LIKE '%Metric%') AND Score_Dec IN ('4', '5', '6') 
         THEN @NotMet 
         ELSE @Met 
       END), 
    Score_Jan = (CASE 
        WHEN ([Type] LIKE '%Metric%') AND Score_Jan IN ('4', '5', '6') 
         THEN @NotMet 
         ELSE @Met 
       END), 
    Score_Feb = (CASE 
        WHEN ([Type] LIKE '%Metric%') AND Score_Feb IN ('4', '5', '6') 
         THEN @NotMet 
         ELSE @Met 
       END) 
    ,Score_Mar = (CASE WHEN ([Type] LIKE '%Metric%') AND Score_Mar  IN ('4','5','6') THEN @NotMet ELSE @Met END) 
    ,Score_Apr = (CASE WHEN ([Type] LIKE '%Metric%') AND Score_Apr  IN ('4','5','6') THEN @NotMet ELSE @Met END) 
    ,Score_May = (CASE WHEN ([Type] LIKE '%Metric%') AND Score_May  IN ('4','5','6') THEN @NotMet ELSE @Met END) 
    ,Score_Jun = (CASE WHEN ([Type] LIKE '%Metric%') AND Score_Jun  IN ('4','5','6') THEN @NotMet ELSE @Met END) 
    ,Score_Jul = (CASE WHEN ([Type] LIKE '%Metric%') AND Score_Jul  IN ('4','5','6') THEN @NotMet ELSE @Met END) 
    ,Score_Aug = (CASE WHEN ([Type] LIKE '%Metric%') AND Score_Aug  IN ('4','5','6') THEN @NotMet ELSE @Met END) 
    ,Score_Sep = (CASE WHEN ([Type] LIKE '%Metric%') AND Score_Sep  IN ('4','5','6') THEN @NotMet ELSE @Met END) 
WHERE 
    Metric = 'Balance Scorecard' 

我一直在尝试不同的组合（铸造，治疗领域INT，文字等），但无济于事。有什么我错过了吗？

下面是结果集：

Metric    Type     Result_Oct Score_Oct Result_Nov  Score_Nov 
AA     1.Monthly Metric  3    3   NULL   NULL 
BB     1.Monthly Metric  292   3   300    3 
CC     1.Monthly Metric  3    3   NULL   NULL 
DD     2.Half Yearly Metric 70   3   NULL   NULL 
EE     2.Half Yearly Metric 100   1   67    4 
Balance Scorecard 3.Accountability  NULL   MET   NULL   MET 

资产负债Scoredcard应该是“不符合”的“Score_nov”为EE度量> = 4，但它似乎是一个查询不能承认的数字。是否因为字段为空？

问题是这些值在不同的行。所以，你需要一个JOIN把它们放在一起。

下面是于11月示例中的其他月份基本相同：

UPDATE t 
    SET score_Nov = (CASE WHEN CAST(tt.Score_Nov AS INT) >= 4 
          THEN @NotMet ELSE @Met 
        END) 
    FROM #TmpTbl t CROSS JOIN 
     #TmpTbl tt 
    WHERE t.metric = 'Balance Scorecard' AND tt.metric = 'EE';
