Kihlman's SQL - a graphic SQL tutorial |
The program is designed to help you master SQL statements. It can be used as an interface against a database. You can also do the test taking you through different levels of difficulty. |

It is also possible to create new tables and views.
Error messages tell you if your spelling is not correct and what is wrong with an SQL statement. |
It is not possible to learn the answers by heart since the names of tables and fields changes each time the program is started. The number of combinations is almost 60 million! |
|
The program is shareware and free for private use at home. If you use it at work the registration fee is $10 and a school can install it for $100. On registration schools get another version which makes it possible to do exams. |
