UPDATE VIEW
Generally, the PL/SQL views are read-only, but it is still possible to update data through a view under some conditions. Let’s understand this with an example:
Let’s take an example, where we need to update the department of employee 1 from “Sales” to “Customer Service,” using the “employee_view.”
UPDATE employee_view
SET department = 'Customer Service'
WHERE employee_id = 1;
Explanation: In PL/SQL, we cannot directly update the data of an already created view because views are typically read-only representations of data. However, we can modify the underlying query of the view to include updated data.
PL/SQL VIEW
In PL/SQL, views are virtual tables created by stored queries, providing a dynamic view of data from one or more tables. Unlike physical tables, views do not store data themselves but act as convenient, encapsulated queries.
In this article, We will learn about the VIEW in PL/SQL in detail by understanding the CREATE VIEW, UPDATE VIEW and DROP VIEW with the examples in detail.
