The SQLiteOpenHelper and SQLiteCursor classes are described, with a focus on how they may be used to perform create, read, update, and delete (CRUD) actions on a SQLite database.

Create an SQLite Database as follows: A table called “Product” with the fields: _id, Name, StockOnHand, StockInTransit, Price, ReorderQuantity, ReorderAmount. StockOnHand – this represents how many of a Product is currently in the Warehouse/Store. StockInTransit – this represents how many of a Product has been ordered and is on its way, not yet received. Price – this is the cost of a Product. ReorderQuantity – this is the number at which stock levels must reach before a purchase order must be made. If StockOnHand is less than ReorderQuantity + StockInTransit, then a purchase order is necessary. ReorderAmount – this is the amount to be purchased when a reorder is made.

PATHS is a table that contains information about paths on a number line. The structure of PATHS is as follows, where x1 and x2 represent that there is a path from Coordinate x1 to Coordinate x2 (You can't move from Coordinate x2 to Coordinate x1 ). NAME ΤΥΡE NULLABLE X1 INT FALSE X2 INT FALSE Problem Please write an SQL statement that returns the beginning and end point of each path in PATHS . Sort them by the value of the beginning point in ascending order. Constraints • In the case where a direct path from Coordinate a to Coordinate b is available, no path from Coordinate b to Coordinate a will be given. |x1-x2| = 1 • No path will overlap with one another. Example Suppose that PATHS is as follows: x1 x2 1 2 2 3 4 7 7 6 This table can be visualized as follows: START END END START 7 8. 9 Therefore, your SQL statement must return the following: start end 1 4 8 6

SQL Queries Specify the following SQLite queries on the chinook database.  A schema for the database is in the picture. You can access the database online through your web browser at the SQLite Tutorial, or you can download the chinook.db database from the tutorial site and run it on a labnet machine or your own machine.  SQLite is already installed on labnet machines. You must submit typed queries, not handwritten ones, and save them in a .pdf document.  There is no need to submit the output (results). Each query is worth 1 mark, but some are more difficult than others.   Queries to Specify 5. List the customer id, last name and email address of all customers with a Yahoo or Hotmail email address. 6. List the album id and number of tracks for all albums with 15, 16 or 17 tracks, in descending order of the number of tracks. 7. Find the maximum track length in milliseconds. 8.
