I am interested in getting sql language certification. I have some knowledge and would want to know how much I have to learn more to pass the exam. Also which site to use for passing, so it would be worth spent money, so my resume would look better? I did quick google search and found
but I have no idea how employers are thinking about this - is it good or not? The price looks decent - 10$ and if want to retake then 5$.
There is also http://www.w3schools.com/cert/default.asp
php and sql certification, but it costs much more. 95$. Does it make it more worth or what?
Can you give some more info about those certifications?
