in thread last_insert_id() in sybase

From DBD::Sybase

The last_insert_id() call is simply a wrapper around a "select @@ident +ity" query. To be successful (i.e. to return the correct value) this +must be executed on the same connection as the INSERT that generated +the new IDENTITY value. Therefore the statement handle that was used +to perform the insert must have been closed/freed before last_insert_ +id() can be called. Otherwise last_insert_id() will be forced to open + a different connection to perform the query, and will return an inva +lid value (usually in this case it will return 0).
Try adding ->finish()
for (my $x=0;$x < 5;$x++){ $insertStatement->execute() or die($DBI::errstr); $insertStatement->finish(); my $id = $dbh->last_insert_id(undef,undef,undef,undef) or die "no insert id $DBI::errstr $!"; print "ID :",$id; update1($id); }
