获取字符串开始的地址(案例)

在下面这篇《https://www.cnblogs.com/insus/p/11064685.html中，仞仅中截取电话号码，如果想获取字符串开始的地址呢？

可以写另外一个函数：

 

SET ANSI_NULLS ON
GO
SET QUOTED_IDENTIFIER ON
GO

CREATE FUNCTION [dbo].[svf_CutterAddress] 
(
    @source NVARCHAR(4000)
) RETURNS NVARCHAR(4000)
AS
BEGIN
    DECLARE @L INT = LEN(RTRIM(@source))    
    WHILE @L > 0
    BEGIN
        DECLARE @cutstr CHAR(1) = SUBSTRING(@source,@L,1)
        IF @cutstr LIKE '%[^-0-9]%'         
            BREAK;    
        SET @L = @L - 1
    END
    RETURN RTRIM(LTRIM(SUBSTRING(@source,1,@L)))
END
