Database Challenges

Out of the large number of solutions we tested, many of them failed the Basic Testing. In most cases the reason for failure was incorrect data. A few solutions failed the test because they either produced incorrect number of columns or they could not produce the columns in the correct order.

Note that the challenges are 'always ON', which means that you can submit a solution at any time. You can submit a new solution even after the results are published. If your solution is disqualified due to one of the reasons given above, you can re-submit a new version of the challenge at any time.
