SQL – remove trailing “/” in url with querystring

I have table with 2 columns where in one of them an url is stored.

Now I would need to update the table to remove all trailing slashes from the urls, including urls that have a query string.

Examples:

/page/sub/1/             =>    /page/sub/1
/page/sub/1/?page=1      =>    /page/sub/1?page=1

I’ve found how to do it for a trailing slash, but not when it’s inside the url.

UPDATE TABLE 
SET MyUrl = LEFT(MyUrl, LEN(MyUrl) - 1) 
WHERE RIGHT(MyUrl, 1) = '/';

Does anyone have an idea how to do this? Can I use a regex of some kind?

Answer

UPDATE TABLE SET MyUrl = replace(MyUrl, '/?', '?') WHERE MyUrl like '%/?%';
