How to Create a New Schema in SQL for Better Organization
Create a Schema
Write a SQL query to create a new schema in the database.
Solution:
-- Create a new schema named "HR".
CREATE SCHEMA HR; -- Define a new schema for organizing database objects.
Explanation:
- The goal is to create a new schema named HR in the database.
- This demonstrates how to use the CREATE SCHEMA statement to organize database objects into logical groups.
- CREATE SCHEMA HR : Specifies the creation of a new schema named HR.
- A schema is a namespace that contains database objects such as tables, views, indexes, and procedures.
- Schemas help organize database objects into logical groups, making it easier to manage large databases.
- They also provide a way to separate objects for different applications, teams, or purposes (e.g., HR, Sales, Finance).
- For example, in a company database, you might create an HR schema to store all tables and objects related to human resources, such as employee records, departments, and payroll data.
