Master SQL for Data Analysis - Overview-5

The video tutorial introduces the concept of conditional logic in programming, focusing on the SQL CASE statement. It explains how the CASE statement can mimic the if-else logic found in many programming languages, allowing for navigation of SQL code based on conditions. The tutorial highlights its applications in data science, such as data cleaning and transformation, and discusses how CASE evaluates conditions to return specific results.

• Performing data encryption

• Generating random numbers

What is one of the main uses of the CASE statement in SQL?

• To join multiple tables

• To create tables

• To delete records
