Java Hibernate Basics Data Persistence & ORMs Using JDBC to Connect to a Database

Connect JDBC to insert new Values --Hibernate Basics

I'm getting the error that says my Insert statement is improper. Where am I going wrong with this?

Application.java
// Load class "org.sqlite.JDBC"
Class.forName("org.sqlite.JDBC");

// Establish connection to database named "treehouse.db"
try(Connection c = DriverManager.getConnection("jdbc:sqlite:treehouse.db")) {

  //INSERT 1 Row into Language table ID Column should have a value of 2 and name should be "Java"

  //First create a sql statement.
  Statement statement = c.createStatement();
  statement.executeUpdate("INSERT INTO language(id, name) VALUES (2, 'Java')");


} catch(SQLException ex) {

}

I actually figured it out, looks like I need to see if the table exists and if it doesn't create the table. Then execute the code.

This ended up working: // Load class "org.sqlite.JDBC" Class.forName("org.sqlite.JDBC");

// Establish connection to database named "treehouse.db" try(Connection c = DriverManager.getConnection("jdbc:sqlite:treehouse.db") ){ Statement statement = c.createStatement(); statement.executeUpdate( "DROP TABLE IF EXISTS languages"); statement.executeUpdate("CREATE TABLE languages (id INTEGER PRIMARY KEY, name STRING" ); statement.executeUpdate(" INSERT INTO languages(id, name) VALUES( 2, 'Java')"); } catch(SQLException ex) { System.err.printf("There was a database error: %s%n",ex.getMessage()); }
