标题: MYSQL教程之有用的数据库反省程序(3)
如IBM公司最近宣布让渠道合作伙伴分销其SaaS应用程序的新计划。微软认为MySQL学习教程是销售其云计算服务的重要组成部分。然而即使有这种趋势，DBaaS仍然不同于内部数据库，解决方案提供商必须认识到这一点;否则，他们不仅仅是丢失几个客户，而是要失去的更多。程序|数据|数据库

你不用花费很多时间和金钱来培训现有的职工，或者去花大价钱雇用那些拥有各种证书的开发者。因为MySQL的维护和管理在很大程度上是“傻瓜型”的。

可能有的朋友会抱怨集成的orderby，其实如果使用ranking函数,Orderby是少不了的。如果担心Orderby会影响效率，可以为orderby的字段建立聚集索引，查询计划会忽略orderby操作（因为本来就是排序的嘛）。

大侠们有推荐的书籍和学习方法写下吧。

同样会为索引视图等应用带来麻烦。看看行级和事务级的快照数据放在tempdb中，就能感觉到目前架构的尴尬。

对于数据库来说，查询是数据库的灵魂，那么SQL查询效率究竟效率如何呢？下文将带对SQL查询的相关问题进行讨论，供您参考。

可以动态传入参数，省却了动态SQL的拼写。

原来公司用过MYSQL自己也只是建个表写个SQL

一直以来个人感觉SQLServer的优化器要比Oracle的聪明。SQL2005的更是比2k聪明了不少。（有次作试验发现有的语句在200万级时还比50万级的相同语句要快show_text的一些提示没有找到解释。一直在奇怪。）
