I've now switched to TBetterADO 4.04 and even though that product properly populates TFieldDefs, neither TBetterADODataset nor Borland's own TADODataset seem to populate TIndexDefs!?! Programatically, how can I detect what is the primary key field for an ADO dataset? Or if indeed, a table even has a primary key?... or any secondary key(s)?

Connection string below: Provider=SQLOLEDB.1;Integrated Security=SSPI;Persist Security Info=False;Initial Catalog=pubs;Data Source=BRYAN240 Authors table has two indexes: Primary plus a secondary on LName + FName, but IndexDefs.Count = 0.
