The Dataset and Query dialog in Jaspersoft Studio is a versatile tool that allows users to manage data adapters, select query languages, and configure queries with ease. Here are the key functionalities:

  • Data Adapter Selection: Users can select a data adapter to configure the dataset. While a default adapter is usually selected, it can be changed as needed.
  • Query Language Selection: Users can choose a query language for the dataset being edited. This could be the main dataset or a sub-dataset used in charts or tables. Supported languages include SQL, XPath, and JSON.
  • Query Specification: Users can specify the query by typing it directly or by using a tool designed for the selected language. This makes it accessible for users with varying levels of expertise.
  • Field Retrieval: Fields can be retrieved from the selected data adapter. These fields can be provided directly by the adapter or by executing the query and reading the response metadata.
  • Field and Parameter Management: Users can add, edit, and remove fields and parameters as needed.
  • Sort Options: Sorting options can be edited to organize data effectively.
  • Record Filtering: An expression can be provided to filter dataset records, ensuring that only relevant data is included.
