· The pseudo column LEVEL is not supported in MaxDB.
· Pseudo column ROWID can only be used if the option ROWID was specified in the CREATE TABLE statement. In contrast to Oracle, MaxDB produces a logical column identification of the data type RAW(8).
· In MaxDB, pseudo column ROWNUM cannot be used in the UPDATE statement.
· The pseudo column ROWNUM is entered into a selected column (select_column) after the result table has been sorted.
