This resource does really help in studying SQL.
A number of interactive exercises lead you from beginner to master.
You'll can solve any practice task if you pass through at least 100 exercises or so.
Excellent support is provided.
The BEST resource of ever I've seen at last 12 years. I'm sure that if you wish to learn SQL in maximum efficient way you have to go to this site and just solve their exersizes. Definitely good and stable knowledge of SQL will come to you after 2-3 monthes after beginning.
It's not so easy to solve exersizes, but it's really usefull spend of time. Good knowledge of SQL as a result. Site contains a lot of interesting and unusual task for e.g. - prime numbers generation and etc.
Wow. I like it. Close you twitter, facebook, etc. and try to solve exercises. You may spend a lot of time but not in vain.
Very good resource. Not only in learning SQL but also in rising your IQ level! Many hours of very interesting useful work, new knowledge, joy of decision, pride for yourself - what would be better!?
If your work is very intensive and you don't have much spare time, DON'T GO THIS WAY!!!Because, after about a week you will realize that you are spending more than half of your time trying to solve problems, and will be punished by your boss :)
This site has some kind of narcotic effect, rising from the place, which is expressed by a 4 digit number to places expressed by 2 digit number will make you more and more dependent. As you solve problems, you will be very glad to go on to forum and read ALL the posts carefully. There will be very funny solutions as well as very genius ones. The forum is organized such that, you will see that you are far not the most stupid person on the site, but at the same time there are LOTS ans LOTS of thing for you to learn.
very very motivating tool.
nice thing instead of conversation with candidates on job
just 'tell me what is you rate in sql-ex and i tell you your salary in our company' :-)
It's a very useful site.

I've passed the offered basic level certification. It's not an easy thing, I should say. It has taken several month to solve 84 exercises, but it is worth it! I've learned a lot.
The project team is friendly and helpful. One thing may upset foreign students — the quality of english texts is not always superb, though they work on its improvement.
It is the best site for study SQL! It is have best support!
