为了使用这个例子，让我们假设我们需要显示销售人员的id和数量，数量要以文本形式显示。

按照下面的步骤来创建一个报表。

1. 创建一个SSRS项目。

2. 添加新报表到这个项目中。

3. 添加一个数据源，它的数据库指向adventureworks。

4. 用上面的查询创建一个数据集。

5. 从工具箱拖拉一个表来进行显示，并拖拉字段到这个表上。

下一步是创建一个函数来转换数字类型为文本。

SQL Server报表服务(SSRS)对于开发人员和用户来说是一个非常有用的设计和浏览报表的工具。但是，有些特性是在SSRS中没有提供为直接可以使用的。 这些特性是开发人员和用户经常需要的。

到报表菜单选项中选择报表属性。选择对话框中的代码标签页并复制和黏贴下面的代码：
