量級數據分頁方案

SELECT * FROM yundou_v3.bill_info WHERE id>= (
    select id as id from yundou_v3.bill_info order by id asc limit 100,1
) limit 20;

SELECT * FROM yundou_v3.bill_info WHERE id>= (
    select id as id from yundou_v3.bill_info order by id asc limit 400000,1
) limit 20;

SELECT * FROM yundou_v3.bill_info WHERE id>= (
    select id as id from yundou_v3.bill_info order by id asc limit 600000,1
) limit 20;

SELECT * FROM yundou_v3.bill_info WHERE id>= (
    select id as id from yundou_v3.bill_info order by id asc limit 800000,1
) limit 20;

SELECT * FROM yundou_v3.bill_info WHERE id>= (
    select id as id from yundou_v3.bill_info order by id asc limit 1000000,1
) limit 20;

實現步驟：

1.獲取start_id

select id as start_id from yundou_v3.bill_info order by id asc limit  n*page_size ,1

2.獲取start_id後面的n條數據

SELECT * FROM yundou_v3.bill_info WHERE id>= 「start_id」 limit 20;
