存储过程 两次排序加一次随机取数据

sql

过程逻辑 先根据id倒序查询到2000条数据，再从这1000条数据中根据金额从大到小查出100条数据，且这100条数据随机取出

CREATE DEFINER=`root`@`%` PROCEDURE `NewProc`()
BEGIN

-- 临时表存在就删除

DROP TABLE IF EXISTS SalesSummary; 
CREATE TEMPORARY TABLE SalesSummary (
     id INT NOT NULL, 
		 user_id INT NOT NULL DEFAULT 0.00,
		 money DECIMAL(12,2) NOT NULL DEFAULT 0.00, 
		 remark VARCHAR(50)  NOT NULL ,
		 note VARCHAR(50) NOT NULL,
		 type TINYINT(3) NOT NULL,
		 created_at TIMESTAMP NOT NULL,
	   updated_at TIMESTAMP NOT NULL,
		 money_type VARCHAR(1) NOT NULL,

-- 临时表存在就删除

-- 将那一百条数据放到临时表
INSERT  INTO  SalesSummary  select a.id,a.user_id,a.money,a.remark,a.note,a.type,a.created_at,a.updated_at,a.money_type,a.business_id,b.nickname from money_logs as a left join users as b on a.user_id=b.id WHERE `type`=1 or `type`=4 or `type`=5 order by id desc limit 2000;
-- 根据money获取10条数据到临时表
INSERT  INTO  SalesSummaryB  select * from SalesSummary order by money desc limit 100;
-- 增加字段
ALTER TABLE SalesSummaryB ADD  temp_id INT NOT NULL  auto_increment primary key;
-- ALTER TABLE SalesSummaryB ADD nickname VARCHAR(50);

-- 随机打乱临时表表中的全部数据
select * from SalesSummaryB order by rand() limit 100;
