这是要去除字段中的大小写英文、数字、特定符号

函数如下：

Create Function [dbo].[RemoveCharacters](@Temp VarChar(1000)) 
Returns VarChar(1000) 
AS 
Begin 

    Declare @KeepValues as varchar(50) 
    Set @KeepValues = '%[a-z,A-Z,0-9,%,/,=,-,#,，,:,;]%' 
    While PatIndex(@KeepValues, @Temp) > 0 
     Set @Temp = Stuff(@Temp, PatIndex(@KeepValues, @Temp), 1, '') 

    Return @Temp 
End 

 

调用方法

Select dbo.RemoveCharacters('这是AB中文abv的0,1范例223')
