This course runs for a duration of 1 Day.
The class will run daily from 9 AM ET to 5 PM ET.
Class Location: Virtual LIVE Instructor Led - Virtual Live Classroom.
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.
After completing this course, learners should be able to:
Explain the role and use of SQL dialects (DDL, DML, and DCL) in managing and interaction with Db2 databases
Summarize the new and deprecated features of Db2 v12, such as enhanced query optimization
Retrieve rows based on comparisons to numeric or alphanumeric column values
Implement correlation names in queries to simplify table references
Implement rounding and truncation functions, including ROUND and DECIMAL
Utilize the GROUP BY clause to categorize data into meaningful subsets and the HAVING clause to filter grouped results based on aggregate conditions
Apply date and time functions to extract, manipulate, and compare date, time, and timestamp values in SQL queries
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
Explain the role of subqueries in SQL and how they differ from standard joins in retrieving data
Explain the role of transaction management using COMMIT, ROLLBACK, and SAVEPOINT to control database changes
