Description

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.
