Replace command & backslash

[Mauro Miotello]

I'm using MySql 5.6 on CentOS 6.5 and i need to change backslash chars in some columns of my table. I've found some errors so i've decided to test replace command with simple string:

SELECT REPLACE('ashnet.it\maurizio\', '\', '/'); -> error 1064

SET sql_mode = NO_BACKSLASH_ESCAPES;
SELECT REPLACE('ashnet.it\maurizio\', '\', '/'); -> no error but no replace done

SELECT REPLACE('ashnet.it\maurizio\*', '\', '/'); -> replace done !

someone know why adding * the replace is done ?
