PL/SQL Views: How to Check View Definitions

To view the definition of a view, you can use the following method:

1. Utilize the DESCRIBE command: Enter the following command in the SQL*Plus command line.

DESCRIBE [视图名称];

This will display information such as column names, data types, and constraints of the view.

1. You can use the SELECT statement to retrieve all view definitions. For example:

SELECT * FROM USER_VIEWS WHERE VIEW_NAME = '视图名称';

This will display the definition information of the specified view.

1. To use user views: In SQL*Plus, you can use the following query to view all views created by the user:

SELECT VIEW_NAME FROM USER_VIEWS;

This will list the names of all views created by the current user.

In addition to the methods mentioned above, you can also use database management tools to view the definition of views.
