Description
TDataSetInsert is a
TDataSetAction descendant which
inserts a new record into the dataset for the target DataSource. The new
record has blank values in each of its fields, and allows editing of the
field values.
Positioning of the inserted record is actually determined using the facilities for the underlying database engine. In most cases, the record is simply appended to its data store and ordered using the indexing facilities for the database engine. Some database engines require an additional step to make the record insertion and/or field editing permanent; i.e. SQL databases require use of a COMMIT statement to flush the changes to the database engine.
TDataSetInsert calls the Insert method for the target dataset to
perform the database action.
