Description
The event that fires when the Local SQL engine looks for a dataset object.
Use the OnGetDataSet event handler to submit a dataset object by its name.
This event can be used to dynamically provide a dataset, without registering it first with the Local SQL engine. The value of the AName
and ADataSet.Name
arguments may be different. After returning a dataset, it will be registered in the DataSets collection under the AName
argument value.
The event handler must return ADataSet
, AAdapter
, or both arguments assigned. For FireDAC datasets, only ADataSet
can be assigned. For non-FireDAC datasets we recommend that you assign both arguments.
