sql expert needed urgently

1. With what SQL query could you select from films the titles of all sequels to Toy Story, including Toy Story 2, Toy Story 3, and any future (similarly numbered) sequels? 2. With what SQL statement could you insert Hannibal (2001), the sequel to The Silence of the Lambs (1991), which earned 16% more than its predecessor? We leave it to you to decide how to insert a percentage. 3. It turns out that each column in a SQLite database has a "type affinity," the recommended type for data stored in that column which can be any of TEXT, NUMERIC, INTEGER, REAL, and BLOB. But each value stored in a SQLite database has a "storage class" (i.e., actual type, which determines how the value is stored on disk), which can be any of NULL, INTEGER, REAL, TEXT, and BLOB. It would seem that NUMERIC, then, is not an actual type, just an affinity. According to SQLite’s documentation, what storage class would SQLite use to store the 16% you just inserted? Why? 4. Notice how this table contains some data redundantly. Not only does Toy Story 2 (1999) appear as a film, it also appears as a predecessor, with its title and year repeated (in other columns). Suppose that this table must be dropped and replaced with (at least) two tables that, together, eliminate that redundancy. With what SQL statements could you create those new tables? We leave the tables' names to you as well as the names of the tables' columns and types thereof. No need to insert any rows into the new tables.
