Description
Sets an optional custom parameter, associated with a dataset.
Use SetOptionalParam method to set a custom parameter value, associated with dataset.
The parameter value may be retrieved using GetOptionalParam. The optional parameters are part of internal dataset storage and are saved / loaded with the dataset at SaveToStream / LoadFromStream calls. FireDAC does not interpret these parameters in any way.
The method is for the TClientDataSet compatibility.
