  • Course SQL Fundamentals : Content

    In the course SQL Fundamentals the widely used and generic query language SQL is discussed. SQL is the abbreviation for Standard Query Language and is an ANSI and ISO standard that can be used in all relational database management systems (DBMS). With SQL you can retrieve data from databases as well as modify data in databases.

    SQL Intro

    The course SQL Fundamentals starts with a treatment of the SQL Standard. The structure of relational databases with tables and their relationships is covered. SQL can be used in many database systems such as Oracle, MySQL, Microsoft Access, Microsoft SQL Server, DB2, Informix, PostgreSQL and more. Almost every DBMS has also added its own extra functions to standard SQL.

    Select Queries

    Next attention is paid to practical skills to write SELECT queries. This also includes clauses such as WHERE, ORDER BY, GROUP BY, HAVING, LIKE and BETWEEN .. AND.

    Data Types

    Then it is time for the different data types used in the SQL language such as numeric, binary and string types. The data types related to dates and time are treated. And the SQL CREATE TABLE statement with which tables are created is discussed as well.


    Part of the program of the course is also the treatment of various functions that are part of the SQL Standard. Among others mathematical, conversion and aggregation functions for calculating sum and average are covered.

    Data Manipulation

    Adding and adjusting data by means of INSERT and UPDATE statements is discussed next. And transactions that either become final with commit or are rolled back with rollback are treated.


    Finally attention is paid to what foreign key relationships between tables are and how JOIN queries can be used to retrieve data from related tables.

    Course Forms

    All our courses are classroom courses in which the students are guided through the material on the basis of an experienced trainer with in-depth material knowledge. Theory is always interspersed with exercises.


    We also do custom classes and then adjust the course content to your wishes. On request we will also discuss your practical cases.

    Course times

    The course times are from 9.30 to 16.30. But we are flexible in this. Sometimes people have to bring children to the daycare and other times are more convenient for them. In good consultation we can then agree on different course times.


    We take care of the computers on which the course can be held. The software required for the course has already been installed on these computers. You do not have to bring a laptop to participate in the course. If you prefer to work on your own laptop, you can take it with you if you wish. The required software is then installed at the start of the course.


    Our courses are generally given with Open Source software such as Eclipse, IntelliJ, Tomcat, Pycharm, Anaconda and Netbeans. You will receive the digital course material to take home after the course.


    The course includes lunch that we use in a restaurant within walking distance of the course room.


    The courses are planned at various places in the country. A course takes place at a location if at least 3 people register for that location. If there are registrations for different locations, the course will take place at our main location, Houten which is just below Utrecht. A course at our main location also takes place with 2 registrations and regularly with 1 registration. And we also do courses at the customer’s location if they appreciate that.


    At the end of each course, participants are requested to evaluate the course in terms of course content, course material, trainer and location. The evaluation form can be found at https://www.klantenvertellen.nl/reviews/1039545/spiraltrain?lang=en. The evaluations of previous participants and previous courses can also be found there.


    The intellectual property rights of the published course content, also referred to as an information sheet, belong to SpiralTrain. It is not allowed to publish the course information, the information sheet, in written or digital form without the explicit permission of SpiralTrain. The course content is to be understood as the description of the course content in sentences as well as the division of the course into modules and topics in the modules.
