C.5 Data Dictionary Mapping

The tables in this section list Oracle data dictionary view names and the equivalent Sybase system tables.

A plus sign (+) indicates that a join operation is involved.

C.5.1 Default Column Values

There is a minor difference between the gateway data dictionary and a typical Oracle database data dictionary.

The Oracle database columns that are missing in an Sybase system table are filled with zeros, spaces, null values, not-applicable values (N.A.), or default values, depending on the column type.
