Abstract
SQLtutor is an interactive online web based tool for teaching and examining students knowledge of SQL. It was introduced into education at the Department of Mapping and Cartography of the Faculty of Civil Engineering at the Czech Technical University in Prague in 2007. The paper informs about the first practical experience gained from the first year of application of the project in education, deals with some uncovered problems and discusses the next possible developments of the project. By introducing the SQLtutor to an introductory database course, there were several goals followed. One of them was to offer the students a learning tool that would help them to impair some casual bad practices brought from secondary schools, like occasional dull mechanical memorizing. This tool would lead them spontaneously to individual learning and logical thinking in order to be able to solve simple SQL queries. The students need to understand basic principles and they need to learn thinking in the categories of sets. A previous knowledge of procedural programming might be paradoxically a disadvantage.
