TCustomClientDataSet.FetchParams Method

Retrieves parameter values from the provider.

Pascal
procedure FetchParams;
C++
__fastcall FetchParams();

Call FetchParams to initialize the Params property with the current parameter values on the provider's dataset. FetchParams does nothing unless the provider's dataset can supply parameter values.

Note: At design time, you can fetch parameter values by right-clicking the client dataset and choosing Fetch Params.
Warning: If the provider is on a stateless application server, the values returned by FetchParams can be changed at any time by other clients. To obtain output parameters from a stateless application server, use the Execute method instead.
