Creating a Report Dataset (Report Builder 2.0)

When you create reports inReport Builder 2.0, you first define one or more data sources and then you create one or more datasets for each data source. Each dataset specifies the fields from the data source that you plan to use in the report, and calculated fields that you can create. In addition to the query and field definitions, a dataset contains a pointer to the data source, query parameters, and data options that include character sensitivities including case, kana type, width, accent, and collation information.

After you create a dataset, you can view the name of the dataset and its field collection in the Report Data pane. From the Report Data pane, you can create additional fields or edit existing fields. For more information, see Working with Fields in a Report Dataset (Report Builder 2.0).

To display data in your report, link a dataset to a data region, such as a table or chart, by dragging fields from the Report Data pane to a data region on the design surface. For more information about each type of data region and the concepts of preparing, filtering, and grouping your data, see Working with Data Regions (Report Builder 2.0), Filtering Data in a Report (Report Builder 2.0), and Grouping and Sorting Data (Report Builder 2.0).

Dataset Features

Report Builder 2.0 provides the following features to help you create datasets that specify the data that you want in your report:

Using Report Models

Report models are, in effect, predefined datasets. Someone with expertise in model design must first create a report model and publish it before it can be used in a report. You can use a report model as a data source for both full-featured reports and for ad hoc reports created in Report Builder 1.0. You do not have to create a dataset query when working with a report model because the model builds the query for you as you work with the data. Report models contain predefined fields and data relationships, called entities and roles, that appear in the Data pane when you select a report model as a data source, and which can be used in the same way that dataset fields are used. For more information about how to build report models, see "Working with Model Designer" in the Reporting Services documentation in SQL Server Books Online. For more information about creating ad hoc reports, see "Working with Report Builder" in the Reporting Services documentation in SQL Server Books Online.
