This is a Firebird exception. It occurs when one transaction has an update or delete pending on a record and another transaction tries to update or delete the same record. It does not block access to the database. Your code needs to handle exceptions.

This is not a Firebird exception. Perhaps it is an ODBC exception of some kind. You need to subscribe to the firebird-odbc-devel list to find solutions to ODBC-related problems. See http://firebirdsql.org/index.php?op=lists
