Coding in RPG (IBM i/AS400). Checking if a record exists in embedded SQL.

In this video, I explore two different ways to check if a record exists in SQL when working with embedded SQL in RPG on IBMi! 🛠️ If you need to verify whether a record is present before updating or inserting data, this video is for you. I’ll show you how to do it using WHERE EXISTS (with two different ways) and COUNT, explaining the pros and cons of each method. No matter your experience level with SQL on IBMi, this will help you write cleaner and more efficient queries! Do you have any other better method ?? please share!
