Java获取Date类型-针对SQL语句

简便使用Date类型：

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


public class test2 {
    public static void main(String[] args) {
        
        do_test2_all();
    }    

    private static int do_test2_all()
    {
        
        try {

            Class.forName("");//空缺
            String url = ""; //空缺
            String userID = "";//空缺
            String passwd = "";//空缺
            Connection conn = DriverManager.getConnection(url, userID, passwd);

            java.util.Date date = new java.util.Date();
            long t = date.getTime();
            java.sql.Date sqlDate = new java.sql.Date(t);
            java.sql.Time sqlTime = new java.sql.Time(t);

            String sql = "";
            PreparedStatement pstmt = null;    
            sql = "select * from student where date=? and id=? and name=?";
            pstmt = conn.prepareStatement(sql);
            pstmt.setDate(1, sqlDate.valueOf("2019-01-01"));
            pstmt.setInt(2, 1234);
            pstmt.setString(3, "test");
            pstmt.executeUpdate();    
            
            pstmt.close();          
            conn.close();
            System.out.println("end");
        }
        catch(ClassNotFoundException e){            
            System.out.println(e.getMessage());
        }
        catch(SQLException e){
            System.out.println(e.getMessage());            
        }

        return 0;
    }
}
