In this video, we will be focusing on the Data Definition Language (DDL) in SQL, specifically the commands for creating, altering, and dropping tables.
Creating tables is an essential part of working with databases, and SQL provides the CREATE TABLE statement for this purpose. We will show you how to specify the columns and data types for your table, as well as any constraints or indexes you may want to include.
Once you have created a table, you may need to modify its structure. The ALTER TABLE statement allows you to add or remove columns, change data types, and modify constraints. We will demonstrate how to use this statement effectively.
Finally, we will discuss the DROP TABLE statement, which allows you to delete a table and all the data it contains. We will explain when and why you might want to use this command.
