解决方案
以下示例使用 getString、getInt 和 executeQuery 方法来获取和显示表的内容。
import java.sql.*;
public class jdbcResultSet {
public static void main(String[] args) {
try {
Class.forName("org.apache.derby.jdbc.ClientDriver");
} catch(ClassNotFoundException e) {
System.out.println("Class not found "+ e);
}
try {
Connection con = DriverManager.getConnection(
"jdbc:derby://localhost:1527/testDb","username", "password");
Statement stmt = con.createStatement();
ResultSet rs = stmt.executeQuery("SELECT * FROM employee");
System.out.println("id name job");
while (rs.next()) {
int id = rs.getInt("id");
String name = rs.getString("name");
String job = rs.getString("job");
System.out.println(id+" "+name+" "+job);
}
} catch(SQLException e) {
System.out.println("SQL exception occured" + e);
}
}
}
