Re: get last oid: msg#00052db.postgresql.odbc
... In a well designed relational Db, every table has a (unique) primary key: if so, you don't even need to know the oid, because the record just inserted is directly reachable using the PK. If your PK uses sequences, you have to get the next seq value "select nextval() from seq_xxxxx..." and use the value obtained for inserting your new row instead of using it as a default value; this way you are protected from concurrent writing to the DB. If you REALLY need the oid from the ODBC connection, I can't help... sorry !
