MySQL ultima varianta - Inserare date in simple views

CREATE VIEW Sumar AS
SELECT nume_client, prenume_client, email_client FROM clients

For a view to be updatable, there must be a one-to-one relationship between the rows in the view and the rows in the underlying table. There are also certain other constructs that make a view nonupdatable. To be more specific, a view is not updatable if it contains any of the following:
    Aggregate functions or window functions (SUM(), MIN(), MAX(), COUNT(), and so forth)
    DISTINCT
    GROUP BY
    HAVING
    UNION or UNION ALL
    Subquery in the select list
    Nondependent subqueries in the select list fail for INSERT, but are okay for UPDATE, DELETE. For dependent subqueries in the select list, no data change statements are permitted.
    Certain joins (see additional join discussion later in this section)
    Reference to nonupdatable view in the FROM clause
    Subquery in the WHERE clause that refers to a table in the FROM clause
    Refers only to literal values (in this case, there is no underlying table to update)
    ALGORITHM = TEMPTABLE (use of a temporary table always makes a view nonupdatable)
    Multiple references to any column of a base table (fails for INSERT, okay for UPDATE, DELETE)
