The answer to this question depends on the View type. There are two types of Views that exist. One is Simple View created from a single table and which does not have any DERIVED columns based on in-built grouping functions like average, sum, etc and the other one is a complex View. We can delete ROWS from views if it is a simpler one but not from Complex one. Let me try to make you understand by going into VIEW definition and syntax.

In SQL, a view is a virtual table dependent on the outcome set of a SQL query. A view contains rows much the same as a real physical table. The fields in a view are fields from at least one real table in the database. You can include SQL functions, WHERE, and JOIN clauses to a view and present the INFORMATION as THOUGH the information were originating from one single table.

There are two types of views that exist. One is the normal one (derived from a single table) and the other one is a complex one (derived from multiple tables). We can delete/update data from view only when it is a normal one and does not have any derived columns based on AVG, COUNT, SUM, MIN, MAX, etc. We can not delete rows from a complex view.
