java初学之JDBC_时间操作_时间段和日期段查询

开门见山，直接贴图和代码，

package mysql;

import java.sql.Connection;
import java.sql.DriverManager;
import java.sql.ResultSet;
import java.sql.SQLException;
import java.sql.Statement;

import com.mysql.jdbc.PreparedStatement;

public class Testjdbc {
public static void main(String[] args){
Connection conn=null;
java.sql.PreparedStatement stmt=null;
ResultSet rs=null;
try{
System.out.println("in db");
Class.forName("com.mysql.jdbc.Driver");
long start =System.currentTimeMillis();
conn = DriverManager.getConnection("jdbc:mysql://localhost:3306/thc","root","123456");
String sql="select * from t_user where regtime between ? and ? ";//预编译&占位符
stmt = conn.prepareStatement(sql);
stmt.setObject(1,"2017-03-28");
stmt.setObject(2,"2017-03-29");

rs=stmt.executeQuery();
while(rs.next()){
System.out.println(rs.getObject(1)+"\t"+rs.getObject(2)+"\t"+rs.getObject(3)+"\t"+rs.getObject(4));
}

}catch(ClassNotFoundException e){
e.printStackTrace();
}catch(SQLException e){
e.printStackTrace();
}finally{
try{
if(conn!=null){
conn.close();

}catch(SQLException e){

}
try{

}
}catch(SQLException e){
