Can we join view with table in oracle?
Please answer to this question
Yes. Consider view as a table and have a condition.
The view is also a table, it is usually derived from two or more tables.
As long as you have a proper joining column, you can join with any related table in the structure. No issues.
A view is a virtual table in the database and it can be derived from two or more tables.
Instead of writing complex queries every time we can store SQL in the view and can utilize it whenever is needed.
We can also join view with a table when we have a proper join column.
Views can improve the query performance.
Yes, we can join a view with a table in Oracle. In fact, joining a view with one or more tables is a common use case for views in Oracle.
When a view is created, it acts as a virtual table that can be queried like a regular table. We can use the SELECT statement to query a view and join it with one or more tables in the same way that we join tables.
For example, consider a view called "employee_salary_view" that contains the names and salaries of employees:
CREATE VIEW employee_salary_view AS
SELECT employee_name, salary
We can join this view with another table, such as a "department_table", to get the department name for each employee:
This query joins the "employee_salary_view" view with the "department_table" table using the "department_id" column, which is assumed to be present in both the view and the table.
So, in summary, we can join views with tables in Oracle using the same syntax as joining tables together
