Details: - test case bug12427262.test was failing on windows because on windows '/' was not recognized. And this was used in LIKE clause of the query being run in this test case. Fix: - Windows needs '\\\\' for path seperater in mysql. I was not sure how to keep a single query with two different syntax based on platform. So modifying query to make sure it runs correctly on both platform.
