JDBC 03: 分页查询

1.　　SQL查询语句

SELECT * FROM web01.user limit X,Y; (从第【X】行开始, 查询Y行)

2.　　实现

public static boolean selectByPage(int pageNum, int pageSize) {
        Connection con = null;
        Statement stmt = null;
        ResultSet rs = null;
        
        try {
            Class.forName("com.mysql.jdbc.Driver");
            
            String url = "jdbc:mysql://localhost:3306/web01?useUnicode=true&CharacterEncoding=UTF8&useSSL=false";
            con = DriverManager.getConnection(url,"root","root");
            
            String sql = "select * from user limit ?,?";
            PreparedStatement pstmt = con.prepareStatement(sql);
            
            pstmt.setInt(1, (pageNum-1)*pageSize);
            pstmt.setInt(2, pageSize);   
 
            rs = pstmt.executeQuery();
            while(rs.next()) {
                System.out.println(rs.getInt("id")+","+rs.getString("username")+","+rs.getString("password"));
            }
            
        }catch (Exception e) {        
            e.printStackTrace();
        } finally {
　　　　　　　　　　// Omitted
        }48         return false;
    }
