## Parameter application cases

In JReport, parameters can be used in many situations. That is, you can apply parameters to many complicated tasks. The usage of parameters in JReport Designer can greatly facilitate your reporting work.

The following topics detail the usages of parameters:

- Using parameters in reports
- Referencing parameters in a formula
- Dynamically filtering queries
- Supplementing WHERE portions
- Binding a parameter to a DBField
- Applying RLS to a parameter
- Filtering a parameter with another parameter
- Dynamically grouping/sorting report data
- Using built-in functions to set date and time parameter values
- Editing the display sequence of parameters
- Controlling multiple parameters
- Importing parameter values
- Applying all values to a parameter in SQL statement

Reference: If you would like to reference parameter features showed in sample reports, you can open the report Parameter_*.cls in the catalog file SampleComponents.cat, which is located at `<install_root>\Demo\Reports\SampleComponents`.
