crystal reports 和sql-server共同进行报表的开发
1：crystal reports功能自述
crystal reports 用于处理数据库，帮助用户分析和解释重要信息。使用 crystal reports 可以方便地创建简单报表，同时它也提供了创建复杂或专用的报表所需的整套工具。
创建所能想象的任何报表
crystal reports 几乎可以从任何数据源生成您需要的报表。内置报表专家在您生成报表和完成一般的报表任务过程中，会一步一步地指导您进行操作。报表专家通过公式、交叉表、子报表和设置条件格式帮助表现数据的实际意义，揭示可能被隐藏掉的重要关系。如果文字和数字确实不够充分，则用地理地图和图形进行形象的信息交流。
将报表扩展到 web
crystal reports 的灵活性并未停留在创建报表这一功能上 ?您可以用各种各样的格式发布报表，包括用 microsoft 的 word 和excel 发布、通过电子邮件甚至 web 发布。高级的 web 报表功能允许工作组中的其他成员在他们自己的 web 浏览器中查看或更新共享报表。
将报表并入应用程序
通过将 crystal reports 的报表处理功能整合到自己的数据库应用程序中，应用程序和 web 开发人员可以节省开发时间并满足用户的需求。crystal reports 支持大多数流行的开发语言，可以方便地在任何应用程序中添加报表。
不论您是 it 行业的站点管理员，还是营销推广经理，也无论您是金融业的数据库管理员还是 ceo，crystal reports 都堪称是一个功能强大的工具，它可以帮助每一个人分析、解释重要信息。
2：crystal reports和sql-server结合
crystal虽然提供了强大的报表功能，但是对于复杂的逻辑运算，却是很难实现。但是，crystal中可以像添加表一样添加存储过程，这就给我们的复杂运算提供了简便的处理方法。
3：例子
这是我们给国航公司it服务项目做的报表的sql-server存储过程部分。（欢迎大家共同讨论）
