Description

Datasets that represent queries and stored procedures use TParams objects to represent the parameters of their query or stored procedures. Client datasets use TParams to represent parameters they pass to a source dataset.

Note: ADO-based datasets do not use TParams objects to represent parameters. They use the TParameters class instead.
Use the properties and methods of TParams to: 

Access a specific field parameter. 

Add or delete field parameters from the list. 

Get or set the values of individual field parameters. 

Compare field parameters. 

Iterate through all field parameters. 

Copy a set of field parameters to another parameter list.
