一、代码如下
package www.tanniu.jdbc;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
public class Statement {
public static void main(String[] args) {
// TODO Auto-generated method stub
Statement s= new Statement();
s.lianJieMysql();
}
private void lianJieMysql() {
// TODO Auto-generated method stub
java.sql.Statement sm= null;
java.sql.Connection cn = null;
ResultSet rs = null;
try {
//加载驱动程序
Class.forName("com.mysql.jdbc.Driver").newInstance();
//得到连接
cn = DriverManager.getConnection(
"jdbc:mysql://localhost:3306/learn?user=root&password=&useUnicode=true&characterEncoding=UTF8");
sm= cn.createStatement();
int i= sm.executeUpdate("insert into user(username, password, phone, email) values('332', '332', '33', '322');");
System.out.println(i);
if(i == 1) {
System.out.println("新增:成功");
}else {
System.out.println("新增:失败");
}
} catch (Exception e) {
// TODO Auto-generated catch block
e.printStackTrace();
} finally {
try {
if(sm != null) {sm.close();}
if(cn != null) {cn.close();}} catch (SQLException e) {e.printStackTrace();}
}
}
}
