import java.sql.Connection; import java.sql.DriverManager; import java.sql.ResultSet; import java.sql.SQLException; import java.sql.Statement; public class Sample { public static void main(String[] args) throws ClassNotFoundException { // load the sqlite-JDBC driver using the current class loader Class.forName("org.sqlite.JDBC"); Connection connection = null; try { // create a database connection connection = DriverManager.getConnection("jdbc:sqlite:sample.db"); Statement statement = connection.createStatement(); statement.setQueryTimeout(30); // set timeout to 30 sec. statement.executeUpdate("drop table if exists person"); statement.executeUpdate("create table person (id integer,name string)"); statement.executeUpdate("insert into person values(1,'leo')"); statement.executeUpdate("insert into person values(2,'yui')"); ResultSet rs = statement.executeQuery("select * from person"); while(rs.next()) { // read the result set System.out.println("name = " + rs.getString("name")); System.out.println("id = " + rs.getInt("id")); } } catch(SQLException e) { // if the error message is "out of memory",// it probably means no database file is found System.err.println(e.getMessage()); } finally { try { if(connection != null) connection.close(); } catch(SQLException e) { // connection close failed. System.err.println(e); } } } } (编辑:李大同) 【声明】本站内容均来自网络,其相关言论仅代表作者个人观点,不代表本站立场。若无意侵犯到您的权利,请及时与联系站长删除相关内容! |
