DBD::mysql::st fetchrow_array failed: fetch() without execute()

[Tim Vantag]

Hi.

I noticed a strange problem in my program.

I have used my program for a months and it has been worked well.

Now I updatet packets (I used yum) and it updated these packets:

mysql.i386 5.0.27-1.fc5
perl-DBD-MySQL.i386 3.0007-1.fc5

Now When I run my program I get lot's of error messages.

DBD::mysql::st fetchrow_array failed: fetch() without execute()

And example here it comes:

$sql_query_string="SELECT id FROM tcaseex WHERE case=? AND tr=?";

#Here I call function
$exist = &select_from_database($sql_query_string,$tid,$trid);

#And here id the function

sub select_from_database {
    my ( $sql_string, @parameters ) = @_;
    $sth = $db_conn->prepare($sql_string) or die "Can't prepare statement: $DBI::errstr";  
    $sth->execute( @parameters )  or die "Can't execute statement: $DBI::errstr";        
    my @a = $sth->fetchrow_array;
    while (my $_f = $sth ->fetchrow_array){
    push(@a, $_f);
    }
  $sth->finish();
 return unless defined wantarray;                                                            
  return wantarray ? @a : "@a"; 
}

So what's wrong now ?
Why I now started to get error messages ?
