从字符串 sql server 中删除数字
我有一个大型数据库，我想在其中进行部分字符串搜索.用户将输入字符:JoeBloggs.
I have a large database in which I want to do a part string search. The user will enter characters: JoeBloggs.
为了争论，如果我在数据库中有一个名字Joe 23 Blo Ggs 4.我想删除 A-Z 以外的名称中的所有内容.
For arguments sake if I had a name Joe 23 Blo Ggs 4 in the database. I want to remove everything in the name other than A-Z.
我有 REPLACE(Name, ' ','') 函数来删除空格和 UPPER() 函数来将名称大写.
I have the REPLACE(Name, ' ','') function to remove spaces and the UPPER() function to capitalize the name.
是否有更有效的快速方法可以通过正则表达式来替换 A-Z 以外的任何内容.我无法更改数据库中的值.
Is there a more efficient fast way maybe by terms of regex to replace anything other than A-Z. I cannot change the values in the database.
