Solution
Yes, we can insert and delete rows into a View. However, there are some conditions that must be met for this to be possible.
For INSERT operations, the view must not contain any of the following:
- A DISTINCT clause
- An aggregate function such as COUNT, SUM, AVG, MAX, or MIN
- A GROUP BY clause
- A UNION operator
- A subquery in the WHERE clause that refers to the same view
- Certain types of expressions, such as calculations, concatenations, or functions
For DELETE operations, the view must be a simple view, not a complex view. A simple view is based on one table, without any calculations or functions, and without any GROUP BY or HAVING clauses.
So, the correct answer is b. Yes, we can insert and delete rows into a View, but under certain conditions.
