PostgreSQL – How to Rename a View

ByAdmin

You can rename a view using the ALTER VIEW statement with the RENAME TO clause in PostgreSQL database. Renaming a view can be useful when you want to change its name to something more meaningful or descriptive. Here’s the basic syntax for renaming a view:

ALTER VIEW old_view_name RENAME TO new_view_name;

where old_view_name is the current name of the view that you want to rename.

and new_view_name is the new name you want to give to the view.

Here’s an example of how you can use this syntax to rename a view. Consider a view named “vw_emp_salary” that you want to rename to “vw_emp_details”. 

ALTER VIEW vw_emp_salary RENAME TO vw_emp_details;

After running this command, the view’s name will be changed from “vw_emp_salary” to “vw_emp_details” while keeping its definition intact. Renaming a view does not affect the view’s underlying query or data; it only changes the view’s name.
