SQL is about 3-5 languages which share some syntax DDL,DML,DQL,cursor manipulation,... And we do currently have seek/read/write for LOs, possibly as a relict from postquel. We also have PL/PGSQL and other PL's that can be used from wihin SQL, so for me the borders between different languages seem quite blurred. What I hoped the standard would have is something like cursor ops on a field in on outer cursors current record. ------------------ Hannu
