Given the structure of the STUDENT table:
Student (id INTEGER, name VARCHAR)
Given:
public class Test {
static Connection newConnection =null;
public static Connection get DBConnection () throws SQLException {
try (Connection con = DriveManager.getConnection(URL, username,
password)) {
newConnection = con;
}
return newConnection;
}
public static void main (String [] args) throws SQLException {
get DBConnection ();
Statement st = newConnection.createStatement();
st.executeUpdate("INSERT INTO student VALUES (102, 'Kelvin')");
}
}
Assume that:
The required database driver is configured in the classpath.
The appropriate database is accessible with the URL, userName, and passWord exists.
The SQL query is valid.
