What does this course tell?
(Please note that the following overview content is from the original platform)


SQL is the standard language for Database Management System. It is used for storage, manipulation and retrieval of data in databases. There are so many features in MySQL that make our task so easy. So, In this tutorial we will be discussing one such feature called Case Statement in MySQL.

The CASE statement consists of a series of conditions. It works like an if then else statement. So, the CASE statement returns a value when the first statement is true. Once a condition is true, it will stop reading and processing further and will return the result. If none of the given statements or conditions is true then the value in the ELSE clause will be returned.

In many cases, there’s not any ELSE clause and when none of the conditions are true and we don’t even have an ELSE clause, then NULL is returned. It’s one of the most fun and important topics to learn in MySQL. To know more about this amazing concept which makes our work so easy and interesting, Watch the complete tutorial.

This course provides an introduction to the CASE statement in MySQL, a powerful feature of the SQL language used for database management. It explains how the CASE statement works like an if-then-else statement, returning a value when the first statement is true and stopping further processing. It also covers the use of the ELSE clause and what happens when none of the conditions are true.

Learners of this course can develop their career in the field of database management and software development. They can also pursue further education in the field of computer science and software engineering.

Learning Suggestions for learners include related topics such as SQL queries, database design, and database optimization. They can also explore other features of MySQL such as triggers, stored procedures, and views. Additionally, they can practice writing SQL queries and explore the use of CASE statements in other programming languages.

[Applications]
After completing this course, learners can apply the knowledge of the CASE statement in MySQL to create efficient and effective queries. They can use the CASE statement to make decisions based on the data in the database. Learners can also use the CASE statement to create complex queries that can be used to analyze data and generate reports. Additionally, learners can use the CASE statement to create stored procedures and triggers that can be used to automate tasks.
