Description
Creates an instance of a TCustomSQLDataSet component.
Call Create to instantiate an SQL dataset component at runtime. SQL datasets placed in forms or data modules at design time are created automatically.
TCustomSQLDataSet is rarely used directly in applications because many of its properties are protected. Instead, applications instantiate TCustomSQLDataSet descendants such as TSQLDataSet, TSQLTable, TSQLQuery, or TSQLStoredProc.
AOwner is the component that is responsible for freeing the dataset. It becomes the value of the Owner property.
