step:
1. Create a function named fun_getPY under the function
2. Write the fun_getPY function, copy the script code
3. Call the function, and view the result
achieve
1, as shown in Figure
2, script code
create function [dbo].[fun_getPY](@str nvarchar(4000))
returns nvarchar(4000)

--set @str=right(@str,len(@str)-1)
set @str = substring(@str,2,len(@str)-1)
end
return @PY
end
3. Call the function
select [dbo].[fun_getPY] ('我是Aimyone！')
//注意：调用函数的时候，函数名要写全[dbo].[fun_getPY]，否则无法识别函数
