正在寻找一个无错误测试的 sql 脚本,我可以在 UDF 中使用它来通过 sql 对 url 进行编码.函数将接收一个 URL 并传递一个 URL 编码的 URL.我看过一些,但我所遇到的似乎都有一些缺陷.
Looking for a bug free tested sql script that i could use in a UDF to encode a url through sql. Function would take in a URL and pass out a URL Encoded URL. I have seen a few, but all i have come across seem to have some flaws.
为了使用此脚本,您需要使用 Numbers 表格.
In order to use this script, you'll want to use Numbers table.
CREATE FUNCTION [dbo].[URLEncode]
(@decodedString VARCHAR(4000))
RETURNS VARCHAR(4000)
AS
BEGIN
/******
* select dbo.URLEncode('K8%/fwO3L mEQ*.}')
**/
DECLARE @encodedString VARCHAR(4000)
IF @decodedString LIKE '%[^a-zA-Z0-9*-.!_]%' ESCAPE '!'
BEGIN
SELECT @encodedString = REPLACE(
COALESCE(@encodedString, @decodedString),
SUBSTRING(@decodedString,num,1),
'%' + SUBSTRING(master.dbo.fn_varbintohexstr(CONVERT(VARBINARY(1),ASCII(SUBSTRING(@decodedString,num,1)))),3,3))
FROM dbo.numbers
WHERE num BETWEEN 1 AND LEN(@decodedString) AND SUBSTRING(@decodedString,num,1) like '[^a-zA-Z0-9*-.!_]' ESCAPE '!'
END
ELSE
BEGIN
SELECT @encodedString = @decodedString
END
RETURN @encodedString
END
GO
该脚本在 SQL Server Central 上完全可用(需要注册)
The script is fully available on SQL Server Central (registration required)
