EasyTable: Single-File Embedded BDE Replacement
Database for Delphi and C++Builder
Indicates whether the underlying database table uses record numbers to indicate the order of records.
function IsSequenced: Boolean; virtual;
Use IsSequenced to determine whether the underlying database table supports sequence numbers, or whether these are computed by the dataset component. When IsSequenced returns True, applications can safely use the RecNo property to navigate to records in the dataset.
As implemented in TDataSet, IsSequenced always returns True. Descendants of TDataSet reimplement this method to return a value that depends on the underlying table type.
