( [id://3333]=superdoc: print w/replies, xml ) Need Help??

I have a simple script which converts access tables to XML.

use XML::Simple; use Data::Dumper; use DBI; my $config = XMLin('c:\website\config.xml', forcearray => qr/table/ ) or die ("unable to open config file"); my ($access_database) = @{$config->{database}}; my ($results_directory) = @{$config->{results_directory}}; my $dsn = "driver=Microsoft Access Driver (*.mdb);dbq=$access_database +"; my $driver = "dbi:ODBC:$dsn"; my $username = ''; my $password = ''; my $dbopt = { PrintError => 0, RaiseError => 0 }; open (LOG,'>c:\website\log.txt') or die "log $!"; my $dbh = DBI->connect($driver, $username, $password, $dbopt) or die "Error connecting: $DBI::errstr"; for $extract (@{$config->{extract}}) { my $results_file = $extract->{file}; my @results; my $ref; for $table (@{$extract->{table}}) { my $sql = "SELECT * FROM $table"; my $sth = $dbh->prepare($sql) or die "Unable to prepare ($sql): ", $dbh->errstr;; $sth->execute or die "Unable to execute ($sql): ", $sth->errstr; $ref->{$table} = $sth->fetchall_arrayref({}); } my $results = XMLout($ref,rootname=>'root', noattr=>1); print LOG Dumper $ref; print LOG $results; print LOG "\n\n"; local *RESXML; open (RESXML, ">$results_directory\\$results_file") or die ("Unable to open results file $results_directory\\$results_fil +e: $!"); print RESXML $results; }

I can't hand out the database, but I can tell you it's pretty simple with a few numeric, date, memo, and text fields.

The problem is that some result sets are empty, even though the database table is populated.

So, I did a little test. I wrote a small script which did nothing more than select * from accommodation. That didn't work. I got no rows in my results set at all.

If I did select count(*) from accommodation, I got the count of the rows.</p?

If I did select <field> from accommodation, that worked fine.

I am more stumped that stumpy the stumpy dwarf.

to format your post; it's "PerlMonks-approved HTML":



  • Are you posting in the right place? Check out Where do I post X? to know for sure.
  • Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
    <code> <a> <b> <big> <blockquote> <br /> <dd> <dl> <dt> <em> <font> <h1> <h2> <h3> <h4> <h5> <h6> <hr /> <i> <li> <nbsp> <ol> <p> <small> <strike> <strong> <sub> <sup> <table> <td> <th> <tr> <tt> <u> <ul>
  • Snippets of code should be wrapped in <code> tags not <pre> tags. In fact, <pre> tags should generally be avoided. If they must be used, extreme care should be taken to ensure that their contents do not have long lines (<70 chars), in order to prevent horizontal scrolling (and possible janitor intervention).
