Trainingsbeschrijving

Naar boven

This course provides an introduction to the SQL language. This course utilizes IBM Data Studio on a Windows 11 operating system, but the SQL queries are appropriate for Linux, UNIX, and Windows environments. 

This course introduces SQL, including syntax, retrieving data from a Db2 table, coding inner joins, arithmetic operations, and scalar and columnar functions. Learners will also explore the UNION function, inserting, updating, and deleting rows, and will use the create table and create view statements.

Additionally, learners will be introduced to advanced functions and performance optimization features in Db2 v12.

Learners will participate in hands-on exercises to practice what they have learned.

  • Identify the impact of special registers, advanced window functions, and AI-driven query optimization on database performance and workload management
  • Differentiate between UNION and UNION ALL and explain how each affects query performance and result set behavior
