Description
Accesses columns by ordinal in the IndexColumns metadata.
TDBXIndexColumnsIndex is used to access columns by ordinal in the IndexColumns metadata collection. These columns are returned when TDBXCommand.Text is TDBXMetaDataCommands.GetIndexColumns when reading metadata. To retrieve metadata columns, use these constants to index the TDBXReader instance returned by TDBXCommand.ExecuteQuery.
