The Ad Hoc View panel provides tools that allow you to control what data is included in a view, and how it is organized.
Along the top of the panel, there is a tool bar and two drop-down menus.
The first drop-down menu allows you to reset the view type. Use this menu to select Table, Chart, or Crosstab. You can change the view type in the Ad Hoc Editor during the design or when you reopen the design for editing.
The next drop-down menu contains options for displaying a subset of the available data (Sample Data, all available data (Full Data), or none of the available data (No Data) in the view. Using the sample data can make the design process quicker by loading less data. Use the subset for initial design; use the full set for refining layout elements such as column width.
By default, the editor displays only a smaller, sample set of the data in the table. Use the drop-down menu to select Full Data to view the full set of data.
| | Depending on its configuration, JasperReports Server may load a Topic, Domain, or OLAP connection’s entire result set into memory when you edit the view, or run a report from it. If the data policies and other options that control JasperReports Server’s memory are disabled, ensure that each Topic, Domain, or OLAP connection returns a manageable amount of data, given the environment’s load capacity. Alternately, you can change the server’s configuration. |

The Layout Band
Directly beneath the tool bar is the Layout Band. Here there are two fields. These fields have different labels and functions, depending on the type of view you are creating:
| • | For tables, these fields are Columns and Groups. |
| • | For charts, these fields are Columns and Rows. |
| • | For crosstabs, these fields are Columns and Rows. |
You can drag and drop fields and measures into these boxes to populate your view.
Managing Canvas Options
When working with a table or chart view, the Canvas Options selector appears below the Layout Band, to the left of the view title. This tool allows you to control the level of detail displayed in your table or chart. Click 
to display the options available for your Ad Hoc view type.
For tables, the Canvas Options selector includes the following options:
| • | Detailed Data displays table detail only. |
| • | Totals Data displays table totals only. |
| • | Details and Totals displays both details and totals. |
For charts, the Canvas Options selector includes the following options:
| • | Chart Types displays the available chart types. |
| • | Chart Format displays formatting options. |
Viewing the SQL Query
You may want to look at the SQL query for your view, to verify what data users are hitting. If you have the proper permissions, you can do this in the Ad Hoc Editor with the View Query button.
The query is read-only, but can be copied onto a clipboard or other document for review.
To view the SQL query:
| • | In the tool bar, click  |
The View Query window opens, displaying the SQL query.
