释义

所谓热销、畅销商品，是指市场上销路很好、没有积压滞销的商品。任何商品，只要受到消费者欢迎，销路好，都可称作畅销商品。

很多人把畅销商品理解为新商品，其实，畅销产品与新旧没有直接的关系，它可能是新商品，也可能是旧商品，而新商品中可能是畅销商品，也可能是销路一般或滞销商品，两者有重叠部分，但不能划等号。

1、这是我们的畅销商品之一。

This is one of our best selling items。

2、对有确定需求、有初始库存和库存短缺的一种畅销商品，建立了供应商管理库存的渠道利润模型。

For a salable product, the channel profit mode of VMI is established, which based is on deterministic demand having safe stock and stock-out cost。

3、这些包括顾客忠诚度、顾客评分和评论、状态提醒、订单跟踪、特价商品、畅销商品和客户账户。

These include loyalty points, customer ratings and reviews, status notifications, order tracking, special offers, best sellers and shopper accounts。

由于各种原因，mysql主从架构经常会出现数据不一致的情况出现，大致归结为如下几类1:备库写数据2:执行non-deterministic query3:回滚掺杂事务表和非事务表的事务4:binlog或者relay log数据损坏数据不同步给应用带来的危害是致命的，当出现主从数据不一致的情况，常见的应对方法是先把从库下线，然后找个半夜三更的时间把应用停掉，重新执行同步，如果数据库的体积十分庞大，那工作量可想而知，会让人崩溃。本文介绍使用percona-toolkit工具对mysql主从数据库的同步状态进行检查和重新同步。一：安装percona-toolkit

是Bison解析器的C语言实现，用于自左至右类语法内容解析生成器。

A Bison parser, made by GNU Bison 241

Bison is a general-purpose parser generator that converts an annotated context-free grammar into a deterministic LR or generalized LR (GLR) parser employing LALR(1) parser tables As an experimental feature, Bison can also generate IELR(1) or canonical LR(1) parser tables Once you are proficient with Bison, you can use it to develop a wide range of language parsers, from those used in simple desk calculators to complex programming languages

Bison is upward compatible with Yacc: all properly-written Yacc grammars ought to work with Bison with no change Anyone familiar with Yacc should be able to use Bison with little trouble You need to be fluent in C or C++ programming in order to use Bison Java is also supported as an experimental feature

sqlserver2005及以上版本可用

with temp1(col1) as

(select 1 col1

union all

select col1 +2 col1

where co11+2<=n)

select sum(col1) from temp1;
