TAstaProvider.Params

Applies to
TAstaProvider

Declaration
property Params: TAstaParamList;

Description
The datasets attached to AstaProviders usually provide a Params property in order to support parameterized queries. If that property is of type TParams, these parameters will be automatically streamed back to the TAstaClientDataSet pointing toward the AstaProvider.

Often however, the TDataSet descendant used on an ASTA server will not use a TParams property but have their own class similar to TParams. ASTA must be able to transalate any Params to a TAstaParamList so it can be safely streamed across process boundries. To do this there are Param Helper Events on the TAstaProvider.
