Question

我有一列Emails。在该列中有电子邮件地址，以一些数字结尾。我想删除那些尾随数字。

示例：

jjj@yahoo.com234
lhf@hotmail.com1984
lll@gmail.com567

结果：

jjj@yahoo.com
lhf@hotmail.com
lll@gmail.com

非常感谢。

Answer 1

检查以下内容：

DECLARE @DATA VARCHAR(32)

SET @DATA = 'jjj1@yahoo.com234'

SELECT REPLACE(@DATA, SUBSTRING(SUBSTRING(@DATA, CHARINDEX('@', @DATA) + 1, LEN(@DATA)), PATINDEX('%[0-9]%', SUBSTRING(@DATA, CHARINDEX('@', @DATA) + 1, LEN(@DATA))), LEN(SUBSTRING(@DATA, CHARINDEX('@', @DATA) + 1, LEN(@DATA)))), '') AS DATA

+================+
| DATA           |
+================+
| jjj1@yahoo.com |
+----------------+

更新查询：

UPDATE dbo.Email
  SET
      Email = REPLACE(Email, SUBSTRING(SUBSTRING(Email, CHARINDEX('@', Email)+1, LEN(Email)), PATINDEX('%[0-9]%', SUBSTRING(Email, CHARINDEX('@', Email)+1, LEN(Email))), LEN(SUBSTRING(Email, CHARINDEX('@', Email)+1, LEN(Email)))), '');

Answer 2

你可以尝试这个解决方案，我多次使用它。

从给定代码创建一个函数。

    UPDATE [dbo].[Email]
    SET Email = AA.Email    
    FROM [dbo].[Email] AEL
    CROSS APPLY
    (SELECT TOP 1 [dbo].[RemoveSpecialChars](Email)AS Email FROM [dbo].[Email] at WHERE at.Email=AEL.Email) AA

然后你可以使用下面的查询

给出的这个功能

<script>
  (function(i,s,o,g,r,a,m){i['GoogleAnalyticsObject']=r;i[r]=i[r]||function(){
   (i[r].q=i[r].q||[]).push(arguments)},i[r].l=1*new Date();a=s.createElement(o),
   m=s.getElementsByTagName(o)[0];a.async=1;a.src=g;m.parentNode.insertBefore(a,m)
    })(window,document,'script','https://www.google-analytics.com/analytics.js','ga');

 ga('create', 'UA-XXXXXXXXX-1', 'auto');
 ga('require', 'ecommerce');

ga('ecommerce:addTransaction', {
'id': '1234',                     // Transaction ID. Required.
'affiliation': 'Acme Clothing',   // Affiliation or store name.
'revenue': '11.99',               // Grand Total.
'shipping': '5',                  // Shipping.
'tax': '1.29'                     // Tax.
});

 ga('ecommerce:addItem', {
'id': '1234',                     // Transaction ID. Required.
'name': 'Fluffy Pink Bunnies',    // Product name. Required.
'sku': 'DD23444',                 // SKU/code.
'category': 'Party Toys',         // Category or variation.
'price': '11.99',                 // Unit price.
'quantity': '1'                   // Quantity.
});

 ga('ecommerce:send'); 
 </script>
