Limit分页通用方案
select * from yundou_v3.bill_info limit 100,20; select * from yundou_v3.bill_info limit 400000,20; select * from yundou_v3.bill_info limit 600000,20; select * from yundou_v3.bill_info limit 800000,20; select * from yundou_v3.bill_info limit 1000000,20;
量级数据分页方案
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;
实现步骤:
1.获取start_id
select id as start_id from yundou_v3.bill_info order by id asc limit n*page_size ,1
2.获取start_id后面的n条数据
SELECT * FROM yundou_v3.bill_info WHERE id>= “start_id” limit 20;
