If you migrated your database to Oracle and elected to use the CREATE RECID FIELD option during the migration, a unique 8-byte Integer column named PROGRESS_RECID will have been automatically generated in your database tables along with a corresponding Index containing the PROGRESS_RECID value as its key.

Databases that are only pulled from the native environment or are migrated without the CREATE RECID FIELD option must either choose a unique index key from each table or the native ROWID to represent the PROGRESS_RECID to support the RECID and ROWID functions, and forward and backward scrolling within their ABL sessions. OpenEdge will internally map the selected unique key or native ROWID to the PROGRESS_RECID and ROWID functions. It is important to note that the unique index key used to derive the OpenEdge ROWID must be a single component index for it to map to the ROWID of a temp-table as described in the following discussion. For more details, see the ROWID function discussion in Initial Programming Considerations.

Also, before discussing ROWID as it relates to the RUN STORED-PROC statement, it is important to understand an important property of the OpenEdge ROWID. See ROWID: Standard ABL behavior for more information.
