@results = GetBookSeller($searchstring);

Looks up a book seller. C<$searchstring> may be either a book seller

C<@results> is an array of hash_refs whose keys are the fields of of the
aqbooksellers table in the Koha database.

sub GetBookSeller {
    my $searchstring = shift;
    $searchstring = q{%} . $searchstring . q{%};
    my $query =
'select aqbooksellers.*, count(*) as basketcount from aqbooksellers left join aqbasket '
      . 'on aqbasket.booksellerid = aqbooksellers.id where name like ? group by aqbooksellers.id order by name';

    my $dbh           = C4::Context->dbh;
    my $sth           = $dbh->prepare($query);
    $sth->execute($searchstring);
    my $resultset_ref = $sth->fetchall_arrayref( {} );
    return @{$resultset_ref};
}

    my $id = shift or return;
    my $dbh = C4::Context->dbh;
    my $vendor =
      $dbh->selectrow_hashref( 'SELECT * FROM aqbooksellers WHERE id = ?',
        {}, $id );
    if ($vendor) {
        ( $vendor->{basketcount} ) = $dbh->selectrow_array(
            'SELECT count(*) FROM aqbasket where booksellerid = ?',
            {}, $id );
    }
    return $vendor;
}

=head2 GetBooksellersWithLateOrders

%results = GetBooksellersWithLateOrders($delay);

Searches for suppliers with late orders.

    LEFT JOIN aqbooksellers ON aqbasket.booksellerid = aqbooksellers.id
    WHERE (closedate < DATE_SUB(CURDATE( ),INTERVAL $delay DAY)

    }

    return %supplierlist;
}

=head2 AddBookseller

$id = &AddBookseller($bookseller);

Creates a new bookseller. C<$bookseller> is a reference-to-hash whose
keys are the fields of the aqbooksellers table in the Koha database.
All fields must be present.

Returns the ID of the newly-created bookseller.

}

#-----------------------------------------------------------------#

=head2 ModBookseller

ModBookseller($bookseller);

Updates the information for a given bookseller. C<$bookseller> is a
reference-to-hash whose keys are the fields of the aqbooksellers table
in the Koha database. It must contain entries for all of the fields.
The entry to modify is determined by C<$bookseller-E<gt>{id}>.

The easiest way to get all of the necessary fields is to look up a
book seller with C<&GetBookseller>, modify what's necessary, then call
C<&ModBookseller> with the result.

    );

=head2 DelBookseller

DelBookseller($booksellerid);
