Description
Moves to a position "before" the first record of the dataset.
Datasnap.DBClient.TCustomClientDataSet.InternalFirst inherits from Data.DB.TDataSet.InternalFirst. All content below this line refers to Data.DB.TDataSet.InternalFirst.
Moves to a position "before" the first record of the dataset.
InternalFirst is called by First. The descendant classes of TDataSet must override this method. The method must implement a "crash" behavior, meaning that the current position must move "before" the first record of the dataset.
