Hi,
Cvetkovski, thanks for rising this question and thanks for providing solutions, running that kind of simple query through phpMyAdmin usually saves life. Otherwise that would be a nightmare to change parameter for 1k products one-by one.
Beside this scheme can be used to mass-change any parameter through phpMyAdmin.
OF COURSE, ALWAYS BACKUP FIRST!!!!! 'cause CTRL+Z wouldn't work once you did something wrong accidentally ;)
I am sure that would help to others.
Thanks.
Case solved. Topic is closed for forum clearance.
