Are all the insert operations inside a transaction?
ie do you notice a
begin ; or
begin work;
line in the initial part of the .sql file
then there shud be a commit; line in the
end of the sql file otherwise the transaction
will rollback.
in case you are inserting from a program you
must send commit instruction to the server.
in DBI/perl eg its $dbh -> commit()
