“How to modify data in a table under a view using SQL?”

To alter the data in a view, you can use the UPDATE statement. Here is an example.

UPDATE view_name
SET column_name1 = new_value1, column_name2 = new_value2
WHERE condition;

In this case, view_name represents the name of the view where data needs to be modified, column_name1 and column_name2 are the names of the columns to be changed, new_value1 and new_value2 are the new values, and condition is an optional parameter used to specify which rows to modify.

Please note that updating a view actually updates the data in the underlying table that the view is based on. Therefore, it may be necessary to update the data in the base table before updating the view.
