Question

我想选择数据。如果它是NULL，将其替换为0并且它是收入所以我需要转换为圆形，这个数据我需要在图表上显示范围明智但问题是我的数据库中的数据不是数字意味着一些特殊字符有' - '，'/'或其他东西，我无法从我的数据库中删除这些字符我想更改我的查询它是字符串，它将替换为= 0 我的查询如下：

SELECT ROUND(ISNULL(REVENUE, '0'), 0) AS Revenue, 
       COUNT(ID)                      AS Counts, 
       CASE 
         WHEN ROUND(ISNULL(REVENUE, '0'), 0) = 0 
              AND ROUND(ISNULL(REVENUE, '0'), 0) <= 5 THEN 1 
         WHEN ROUND(ISNULL(REVENUE, '0'), 0) > 5 
              AND ROUND(ISNULL(REVENUE, '0'), 0) <= 10 THEN 2 
         WHEN ROUND(ISNULL(REVENUE, '0'), 0) > 10 
              AND ROUND(ISNULL(REVENUE, '0'), 0) <= 20 THEN 3 
         WHEN ROUND(ISNULL(REVENUE, '0'), 0) > 20 
              AND ROUND(ISNULL(REVENUE, '0'), 0) <= 50 THEN 4 
         WHEN ROUND(ISNULL(REVENUE, '0'), 0) > 50 
              AND ROUND(ISNULL(REVENUE, '0'), 0) <= 100 THEN 5 
         WHEN ROUND(ISNULL(REVENUE, '0'), 0) > 100 
              AND ROUND(ISNULL(REVENUE, '0'), 0) <= 250 THEN 6 
         WHEN ROUND(ISNULL(REVENUE, '0'), 0) > 250 
              AND ROUND(ISNULL(REVENUE, '0'), 0) <= 500 THEN 7 
         WHEN ROUND(ISNULL(REVENUE, '0'), 0) > 500 
              AND ROUND(ISNULL(REVENUE, '0'), 0) <= 1000 THEN 8 
         WHEN ROUND(ISNULL(REVENUE, '0'), 0) > 1000 
              AND ROUND(ISNULL(REVENUE, '0'), 0) <= 5000 THEN 9 
         WHEN ROUND(ISNULL(REVENUE, '0'), 0) > 5000 
              AND ROUND(ISNULL(REVENUE, '0'), 0) <= 10000 THEN 10 
         ELSE 11 
       END                            AS ranges 
FROM   CT_GLOBALDATA 
WHERE  CREATEDDATE BETWEEN GETDATE() - 30 AND GETDATE() 
GROUP  BY REVENUE 

SELECT REVENUE 
FROM   CT_GLOBALDATA

我创建了函数，它工作正常。我正在上传我的功能以供将来参考

创建功能dbo.udf_GetNumeric_Nitish
（@strAlphaNumeric VARCHAR（256））
退货变量（256）
AS
BEGIN
声明@test varchar（256）声明@intAlpha int 选择@intAlpha = ISNUMERIC（@strAlphaNumeric）
if @ intAlpha = 1

设置@ test = @ strAlphaNumeric

否则

设置@ test ='0'

返回@test
结束

如果数据是字符串类型，则将列替换为“0”
