怎么办？请帮帮我。

Answer 1

这可能会对你有帮助，

SELECT *
        FROM Customer
        ORDER BY Cast(SUBSTRING(CustomerID, 5, Len(CustomerID)) As Numeric(5,0));

Answer 2

如果您知道前缀的长度始终相同，则可以执行以下操作：

order by len(customerid), customerid

Answer 3

使用AMT -函数从字符串中删除RIGHT部分，并将其余部分转换为整数，并按结果对结果进行排序。

SELECT *
FROM customerId
ORDER BY CONVERT(INT,RIGHT(id,LEN(id)-5));

Answer 4

假设所有客户ID都具有相同的前缀（例如AMT-），后缀是数字，您可以使用SubString来获取数值，并相应地进行排序。

CREATE TABLE [dbo].[Customers](
    [CustomerID] [varchar](50) NULL
) ON [PRIMARY]


INSERT INTO [dbo].[Customers]
           ([CustomerID])
     VALUES
           ('AMT-2'),('AMT-100'),('AMT-1'),('AMT-50'),('AMT-10')

declare @prefix varchar(4) = 'AMT-'

SELECT  *--,cast(SUBSTRING(CustomerID,len(@prefix) + 1,len(CustomerID) - len(@prefix) + 1) as int)
FROM    Customers
order by cast(SUBSTRING(CustomerID,len(@prefix) + 1,len(CustomerID) - len(@prefix) + 1) as int)

Answer 5

试试这个order by

order by convert(int,(substring(col,charindex('-',col)+1,len(col))))

Answer 6

如果模式相同，也可以尝试

select customer_id from table
order by substring(customer_id,5,len(customer_id))*1

Answer 7

您可以CAST将列XML输入customerid并从中提取数字，然后根据SELECT * INTO #TEMP FROM ( SELECT 'AMT-1' customerid UNION ALL SELECT 'AMT-2' UNION ALL SELECT 'AMT-10' UNION ALL SELECT 'AMT-50' UNION ALL SELECT 'AMT-100' )TAB列中的数字进行排序。

示例数据

;WITH CTE AS
(
     SELECT  
     -- Actual customerid column
     ISNULL(PARSENAME(Split.a.value('.', 'VARCHAR(100)'),2),Split.a.value('.', 'VARCHAR(100)'))  'customerid' ,
     -- Extract numbers from string and keep a column that sorts the numbers numerically
     ROW_NUMBER() OVER(ORDER BY CAST(PARSENAME(REPLACE(Split.a.value('.', 'VARCHAR(100)'),'-','.'),1) AS NUMERIC(20,0))) 'RNO' 
     FROM  
     (
           -- Converts to XML format
           SELECT CAST ('<M>' + customerid + '</M>' AS XML) AS Data
           FROM #TEMP       
     ) AS A 
     CROSS APPLY Data.nodes ('/M') AS Split(a)
)
SELECT customerid
FROM CTE 
ORDER BY customerid,RNO

Answer 8

DECLARE @t TABLE (CUSTOMER_ID nvarchar(100))
INSERT INTO  @t VALUES ('AMT-2'),('AMT-100'),('AMT-1'),('AMT-50'),('AMT-10'),('AMT-98')

SELECT * from @t 
ORDER BY RIGHT(REPLICATE(N' ', 50) + CUSTOMER_ID, 50)
