ORA-01461 in a msaccess linked table
The problem was that all oracle linked tables in msaccess database, have the link description of an odbc of the previous database version (DBA=W;APA=T;EXC=F;FEN=T;QTO=F;). One of this parameters (Enable LOBs) was diferent and causes the error.
To solve the problem have to relink all the tables of de msaccess database. It's important to relink all, because masccess make the connection to oracle for all the linked table in the first access of any table.
