SQL workshop
During this practical workshop, you will get familiar with intermediate level SQL, which will allow you to read and formulate more complex SQL statements.
A profound training in SQL, the 'de facto standard language for Relational Database Management Systems', is necessary when you want to do more than simple queries on one or two tables. Besides the traditional RDBMS (like Oracle, Db2, SQL Server, PostgreSQL, MySQL ... ), SQL is also supported by non-relational systems such as Hive (used in Hadoop and Spark) and by e.g. SQLite and MS Access.
This course provides a thorough training, both theoretical and (mainly) practical, in the use of SQL, and primarily its data manipulation aspects, i.e., translating business questions into an SQL query. After successful completion of the course, the students will be able to read complex SQL and will be able to formulate their own complex SQL statements in a readable and maintainable way.
This training is mainly practical in nature; it builds on the course SQL and relational databases fundamentals and precedes the more advanced SQL advanced course.
Schedule
No public sessions are currently scheduled. We will be pleased to set up an on-site course or to schedule an extra public session (in case of a sufficient number of candidates). Interested? Please contact ABIS.
Intended for
The training is intended for anyone who wants to write or read SQL queries: analysts, application programmers, database administrators, system programmers, end users ... You can test for yourself to see if this course contains enough new information for you by filling out the on-line self-test.
Background
Some experience with relational databases and SQL (see course SQL and relational databases fundamentals) is an absolute prerequisite. You can test for yourself to see if you have enough background by filling out the on-line self-test.
Main topics
- More advanced SELECT:
- subqueries in WHERE predicates
- nested table expressions • common table expressions (WITH clause)
- correlated subqueries • EXISTS
- scalar subqueries
- group by & having: typical use and "best practices"
- union • intersect • except • minus
- inner join, left/right/full outer join of multiple tables, and when to use
- expressions: case; extract; cast; date & time manipulations
- overview and use of the most useful scalar functions
- INSERT, UPDATE, DELETE
- Hidden mistakes, alternative formulations, query readability, best practices
Training method
Most of the time is devoted to practical exercises and to discussing the solutions. Exercises can be made either on Oracle, Db2 for z/OS, Db2 for LUW, MySQL, MariaDB, SQL Server, or PostgreSQL. (Indicate your choice on the registration form.) After the training, you get access to our on-line database environment, so you can practise at home/work!

Zeer relevante en bruikbare cursus.
| (Sabine de Win, APG, ) |
great course, this has given me the knowledge and practice to start querying on my own. before this course i was a bit hesitant to use SQL.
| (N.N., ) |
Positief, goede afwisseling theorie en oef. Veel nieuwe zaken bijgeleerd.

Voldoet zeker aan de behoefte!
| (Bob Merx, APG, ) |
Zeer uitdagend, maar heeft wel geleid tot extra inzichten en een nieuwe manier van SQL te benaderen. Je bouwt voor jezelf extra controles in om de juiste resultaten te bekomen.
