If you are like many IBM i users, you frequently need to get information from a DB2 database. This request for information, or query, can be easily described and run using the IBM DB2 Web Query for System i product (more frequently referred to as simply DB2 Web Query).
This course begins with an introduction to relational database terminology and DB2 Web Query facilities. You will see how to access and log into DB2 Web Query, and how to access the DB2 Web Query help facility.
You will then see how to define and run queries. Starting with very basic queries, you will proceed to more advanced queries, such as a query that generates summary data and a query that joins two files. The course ends by describing DB2 Web Query's report formatting capabilities.
