5.9 LAB - Database programming with Java (SQLite) Complete the Java program to create a Horse table, insert one row, and display the row. The main program calls four methods: 1. createConnection() creates a connection to the database. 2. create Table() creates the Horse table. 3. insertHorse() inserts one row into Horse. 4. selectAllHorses() outputs all Horse rows. Complete all four methods. Method parameters are described in the template. Do not modify the main program. The Horse table should have five columns with the following names, data types, constraints, and values: Name Data type Constraints Value Id integer primary key, not null 1 Name text Babe Breed text Quarter horse Height double 15.3 Birth Date text 2015-02-10 The program output should be: All horses: (1, 'Babe', 'Quarter Horse', 15.3, '2015-02-10') This lab uses the SQLite database rather than MySQL. Both SQLite and MySQL Connector/J implement the JDBC API. Consequently, the API is as described in the text, with a few exceptions: • Use the connection string "jdbc:sqlite::in-memory" to connect to an in-memory database. • Use the text data type instead of char and varchar. SQLite reference information can be found at SQLite Java Tutorial, but is not necessary to complete this lab. 403894.1874424.qx3zqy
