In the course Queries with Oracle SQL participants learn the syntax and use of the query language SQL in the context of an Oracle database. SQL is an ANSI and ISO standard Query language that is applicable in all relational database management systems (DBMS). With SQL you can both retrieve and modify data in an Oracle database.
After an introduction to relational databases and Oracle, the Oracle installation, environment and tooling, the basic aspects and backgrounds of SQL are discussed. Oracle, like other DBMS systems, has added extra features of its own to standard SQL and these are also discussed in the course.
In the first place the course covers how SQL statements can be created and executed in Oracle. Subsequently the various components of SQL are treated step by step, such as Data Definition Language with CREATE TABLE and Data Manipulation Language with INSERT and UPDATE.
Next attention is paid to writing SELECT queries. The grouping of data by means of GROUP and HAVING clauses is also on the program of the course.
The various functions in SQL are discussed. Among other things, the mathematical, conversion and aggregation functions for calculating sum and average are treated. Attention is also paid to features specific to Oracle.
Next the course covers how to combine data from different tables by means of joins. The various types of joins like inner and outer joins are discussed.
Finally attention is paid to the application of SET operators such as UNION and INTERSECT. The command line interface of SQL*Plus is also treated.
The course Oracle SQL Fundamentals is designed for developers, database administrators and other interested parties who wish to learn and use Oracle SQL.
The course Oracle SQL Fundamentals has no specific requirements. General knowledge of system development and databases is beneficial to a good understanding.
The theory is treated on the basis of presentation slides. Demos are used to explain the theory. There is ample opportunity to practice. The course works with newest Oracle version but is also suitable for older Oracle versions. The course times are from 9.30 to 16.30.
Participants receive an official certificate Oracle SQL Fundamentals after successful completion of the course.

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.
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.
