Description

The CREATE SCHEMA statement is designed to create a new data schema (SCHEMA). By defining the schema name and optional descriptive comments, users can construct a new logical data grouping within the data management system, thereby achieving orderly organization and efficient management of data.

Syntax

CREATE SCHEMA [ IF NOT EXISTS ] schema_name [ COMMENT 'comment' ];

Parameter Details

• schema_name: Specifies the name of the newly created schema.
• IF NOT EXISTS: Optional parameter to prevent errors if the schema already exists.
• COMMENT: Adds a descriptive comment to the new schema to help understand its purpose and content.

Example

1. Create a new schema named customer_data and add the comment "Customer related data":

CREATE SCHEMA customer_data COMMENT 'Customer related data';

2. To avoid errors caused by the data schema already existing, you can use the IF NOT EXISTS parameter:

CREATE SCHEMA IF NOT EXISTS sales_data COMMENT 'Sales related data';

3. Create a data schema with Chinese comments:

CREATE SCHEMA financial_data COMMENT 'Financial Data';

Permission Requirements

The user executing the CREATE SCHEMA statement must have the permission to create a schema. Specifically, the user needs to obtain the corresponding permission points to ensure the successful execution of this operation.
