MySQL: How do I match escaped urls using LIKE or REPLACE : My Situation:

I have url's that are stored in my database with escape characters.

**Original URL:** 

    http://test01.mysite.com

**As Stored in DB:** 

    http:\/\/test01.mysite.com

If I run 

    SELECT
    	*
    FROM
    	table
    WHERE
    	field LIKE '%http://test01.mysite.com%'
    	OR
    	field LIKE '%http:\/\/test01.mysite.com%'
	

zero records are returned.

Similarly, if I run

    UPDATE
    	table
    SET
    	field = REPLACE(field, 'http://test01.mysite.com', 'https://test01.mysite.com')


or


    UPDATE
    	table
    SET
    	field = REPLACE(field, 'http:\/\/test01.mysite.com', 'https://test01.mysite.com')
	
Zero records are affected.

I have also experimented with REGEXP and RLIKE, but I have very limited experience there and my attempts have all resulted in either zero records found or all records containing links being found.


Anybody know how I can write these queries so that LIKE and REPLACE will find matches to those url's?


Any help is greatly appreciated!

Thanks!
