1.實現修改步驟

前三個步驟：注冊、獲得連接，創建statement對象方法，見上一節：

2.使用jdbc刪除數據庫中的數據

這里使用的是queryDemo數據庫，表格為demo1student，表中數據如下：

1）刪除單個數據

代碼演示

import java.sql.Connection; import java.sql.DriverManager; import java.sql.PreparedStatement; import java.sql.SQLException; import java.util.Properties;import org.junit.Test;public class Test11 {// 刪除數據//刪除單個數據 @Testpublic void deleteOne() {Connection connection = null;PreparedStatement ps = null;try {Class.forName("com.mysql.jdbc.Driver");String url = "jdbc:mysql://localhost:3306/queryDemo";Properties info = new Properties();info.put("user", "root");info.put("password", "123");connection = DriverManager.getConnection(url, info);String sql = "delete from demo1student where id between ? and ? ";ps = connection.prepareStatement(sql);ps.setInt(1, 13);ps.setInt(2, 17);int num = ps.executeUpdate();if (num > 0) {// 如果刪除成功，則打印successSystem.out.println("Sucess");} else {// 如果刪除失敗，則打印FailureSystem.out.println("Failure");}} catch (ClassNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (SQLException e) {// TODO Auto-generated catch blocke.printStackTrace();} finally {// 5.關閉資源if (connection != null) {try {connection.close();} catch (SQLException e) {// TODO Auto-generated catch blocke.printStackTrace();}}if (ps != null) {try {ps.close();} catch (SQLException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}}}

運行結果：

1.刪除前

2.刪除后

2）刪除表格中所有數據

代碼演示

import java.sql.Connection; import java.sql.DriverManager; import java.sql.PreparedStatement; import java.sql.SQLException; import java.util.Properties;import org.junit.Test;public class Test12 {// 刪除表格中所有數據@Testpublic void deleteAll() {Connection connection = null;PreparedStatement ps = null;try {Class.forName("com.mysql.jdbc.Driver");String url = "jdbc:mysql://localhost:3306/queryDemo";Properties info = new Properties();info.put("user", "root");info.put("password", "123");connection = DriverManager.getConnection(url, info);String sql = "delete from demo1student";ps = connection.prepareStatement(sql);int num = ps.executeUpdate();if (num > 0) {// 如果刪除成功，則打印successSystem.out.println("Sucess");} else {// 如果刪除失敗，則打印FailureSystem.out.println("Failure");}} catch (ClassNotFoundException e) {// TODO Auto-generated catch blocke.printStackTrace();} catch (SQLException e) {// TODO Auto-generated catch blocke.printStackTrace();} finally {// 5.關閉資源if (connection != null) {try {connection.close();} catch (SQLException e) {// TODO Auto-generated catch blocke.printStackTrace();}}if (ps != null) {try {ps.close();} catch (SQLException e) {// TODO Auto-generated catch blocke.printStackTrace();}}}} }

運行結果：
1.刪除前

2.刪除后
