ROWID is supported by all DataServers. Earlier Progress versions provide RECID as the only way to fetch a record pointer (supported in this version for backward compatibility). RECID is limited to a 8-byte record address supported by only a few DataServers and standard OpenEdge. ROWID provides a variable byte string that can represent a record address for any type of DataServer. For DataServers that use the 8-byte address supported by RECID (including OpenEdge), ROWID also uses a 8-byte value. Thus, there is no loss in performance using the more portable ROWID instead of RECID.
