Getting Started with SQL on IBM i Bootcamp


SQL is the standardized language for defining and manipulating data in a relational database. SQL is the recommended interface from applications into your data on IBM i. And SQL views can access and alter system services procedures, and functions on IBM i.

In short, it is imperative to know SQL.

This bootcamp defines Structured Query Language (SQL) as supported by Db2 for IBM i. It contains basic reference information for the tasks of system administration, database administration, application programming, and operation.

This bootcamp will be delivered in semi-weekly presentations, from November 6, 2023 until January 15, 2024.
