Course facts

  • Knowing the basic SQL concepts: the syntax of SELECT statements (e.g. `WHERE`, `ORDER BY`, `DUAL`, `ROWNUM`), SQL functions (numeric, string, date/time, `DECODE`, `CASE`), `GROUP BY`, `HAVING` and set operations (`UNION`, `INTERSECT`, `MINUS`)
  • Data Manipulation Language (DML) operations (INSERT, UPDATE, DELETE) and transaction control (COMMIT, ROLLBACK, SAVEPOINT)
  • Understanding the data dictionary, the constraints (Primary, Unique, Foreign Key) and the ROWIDs/indexes
  • Knowledge of different types of joins (INNER, CROSS, OUTER, NATURAL, self-joins) and subqueries (synchronous, asynchronous, inlay views, EXISTS, ANY, ALL, WITH)
  • Advanced SQL topics such as detailed data types, `GROUP BY` extensions (ROLLUP, CUBE, GROUPING) and analytical functions (RANK, NTILE, LISTAGG, LEAD, LAG, PARTITION BY)
  • Further advanced areas: Top-N queries, Data Definition Language (DDL) for tables, sequences and views, hierarchical queries, advanced DML (INSERT ALL/FIRST/APPEND, MERGE) and regular expressionsAnswering Oracle database administrators, application administrators, Oracle developers or architects, generally anyone who comes into contact with SQL.

In this workshop, we will teach you advanced techniques and concepts of Oracle SQL. The workshop offers sufficient space for exercises in which the newly acquired knowledge can be implemented or existing knowledge can be deepened. The topics range from the syntax of simple statements to the various joins and subqueries to more specialized topics such as analytical functions, hierarchical queries and regular expressions in SQL.
