Description

Accesses columns by ordinal in the ProcedureParameters metadata.

TDBXProcedureParametersIndex is used to access columns by ordinal in the ProcedureParameters metadata collection. These columns are returned when TDBXCommand.Text is TDBXMetaDataCommands.GetProcedureParameters when reading metadata. To retrieve metadata columns, use these constants to index the TDBXReader instance returned by TDBXCommand.ExecuteQuery.
