Course Structured query language

If you want to easily retrieve data from a relational database, you can use SQL (structured Querylanguage). In addition, you can modify, manipulate, and modify table structures with SQL data. SQL is widespread and is often used in combination with other programming languages such as PHP, ASP and VBA. ANSI SQL is the most popular standardized database language and is now no longer to be thought of when using relational databases. ANSI SQL can be used for querying MS SQL Server, ORACLE, MS Access, PostgreSQL and MySQL databases. Because ANSI SQL is standardized, it can be used with almost all modern relational databases.

In our two-day training SQL Base you will develop knowledge and skills in the FIELD of SQL. Under the guidance of an experienced database trainer, you will actively get to work on creating queries. After this training you have mastered the basics of SQL and can easily create queries to retrieve data.


  • Introduction to SQL, Basic principles: Data types, keys (primary key, foreign key)
  • Retrieving data (SELECT FROM, TOP, DISTINCT)
  • Sort data (ORDER BY)
  • Filter data (WHERE, comparison operators, BETWEEN)
  • Advanced Filters (AND, OR, IN NOT)
  • Filter using wildcards (LIKE)
  • Calculated fields (Concateneren)
  • Customizing data with Functions (ROUND, LTRIM, RTRIM, DATE PART)
  • Summarize data (COUNT, SUM, AVG, MAX, MIN)
  • Grouping data (GROUP BY, HAVING)
  • Working with subqueries (IN)
  • Combine data from multiple tables with join (INNER JOIN, LEFT OUTER JOIN, RIGHT OUTER join)
  • Advanced Joins (Table aliases)
  • Combine queries (UNION)
  • Add data (INSERT INTO)
  • Modify and delete data (UPDATE, DELETE)
  • Create, modify, and delete tables (CREATE, ALTER, DROP)
  • Differences in SQL between database systems


The training is intended for users of relational databases (e.g. Microsoft SQL Server, ORACLE, Microsoft Access, MySQL, Apache OpenOffice Base, IBM DB2, PostgreSQL, SAS and SQLite). The training is suitable for both novice database users and functional administrators and data analysts.
