Data reports are contributor defined queries on tables or views within the underlying Oracle Database.
Before you can add a data report, your Websheet application developer must enable the Allow SQL and PL/SQL attribute on the Websheet properties page. By default, this attribute is disabled. To learn more, see "Editing Websheet Application Properties" in Oracle Application Express Application Builder User's Guide.

Data reports, unlike data grids, are query-only and based on existing data from the Oracle Database. You can specify the table or view name and retrieve all columns or write a SQL statement to retrieve the required data.
Users can alter the layout of report data by selecting columns or by applying filters, highlighting, and sorting. Users can also define breaks, aggregations, group by, computations, and different charts. Additionally, users can create multiple variations of a data grid and save them as named reports, for either public or private viewing. You can also use the data from a data report and include it as a chart or report within any page.
You can create a data report by either simply entering the table or view name, or by providing a SQL query.
