TParameters Class

TParameters manages a collection of parameters.

TParameters = class(TOwnedCollection);
class TParameters : public TOwnedCollection;

Use TParameters to manage a collection of TParameter objects for an object that uses field parameters. For example, TADOStoredProc objects and TADOQuery objects use TParameters objects (in properties named Parameters) to create and access their parameters.  

Use the properties and methods of TParameters to:

  • Access a specific parameter.
  • Add or delete field parameters from the list.
  • Get or set the values of individual parameters.
  • Compare collections of parameters.
  • Iterate through all parameters.
  • Copy a collection of parameters to another parameter collection.
