SHOW CREATE VIEW - MySQL

Overview

The SHOW CREATE VIEW command in MySQL provides a detailed description of a specified view’s definition and structure. It is commonly used for understanding the underlying query and its dependencies.

Syntax

SHOW CREATE VIEW [schema_name.]view_name

Parameters:

  • schema_name (optional): Specify the schema where the view is located. If omitted, the current schema is assumed.
  • view_name: The name of the view to be inspected.

Options/Flags

None.

Examples

Simple Example:

SHOW CREATE VIEW my_view;

Example with Schema Name:

SHOW CREATE VIEW sales.customer_orders;

Common Issues

  • View Not Found: Ensure that the specified view exists.
  • Permission Denied: Check if the user has permission to access the view.

Integration

The SHOW CREATE VIEW command can be combined with other MySQL tools and commands for advanced tasks. For example:

  • Exporting View Definition: Combine with \G to export the view definition as a SQL script.
  • Diffing View Definitions: Use SHOW CREATE VIEW with diff to compare two view definitions.
  • Identifying Dependency: Inspect the query definition to identify tables and views upon which the view depends.
  • CREATE VIEW: Creates a new view.
  • DROP VIEW: Deletes a view.
  • INFORMATION_SCHEMA.VIEWS: Provides comprehensive information about views in the database.
