Introduction to SQL | How to Change Existing Data

Brian Combs

SQL is a core part of working in modern data environments. Sometimes you will need to change data and this session will walk you through inserting and updating records in a table. We’ll apply filtering options to ensure we modify the appropriate data. We’ll cover the basic syntax, how to handle missing values, and very basic performance considerations. The goal of this session is to help you feel confident updating or changing data.

This session is the third in a series of 5 connecting sessions.
