If not present, the parameter marcflavour is used instead C<$z3950random> => the random value created during a z3950 search result. =head1 DESCRIPTION ImportBreeding import MARC records in the reservoir (marc_breeding table). the records can be properly encoded or not, we try to reencode them in utf-8 if needed. works perfectly with BNF server, that sends UNIMARC latin1 records. Should work with other servers too. the FixEncoding sub is in Koha.pm, as it's a general usage sub. =cut @ISA = qw(Exporter); @EXPORT = qw(&ImportBreeding &BreedingSearch); =head2 ImportBreeding ImportBreeding($marcrecords,$overwrite_biblio,$filename,$encoding,$z3950random); TODO description =cut sub ImportBreeding { my ($marcrecords,$overwrite_biblio,$filename,$encoding,$z3950random) = @_; my @marcarray = split /\x1D/, $marcrecords; my $dbh = C4::Context->dbh; my $searchisbn = $dbh->prepare("select biblioitemnumber from biblioitems where isbn=?"); my $searchissn = $dbh->prepare("select biblioitemnumber from biblioitems where issn=?"); my $searchbreeding = $dbh->prepare("select id from marc_breeding where isbn=? and title=?"); my $insertsql = $dbh->prepare("insert into marc_breeding (file,isbn,title,author,marc,encoding,z3950random) values(?,?,?,?,?,?,?)"); my $replacesql = $dbh->prepare("update marc_breeding set file=?,isbn=?,title=?,author=?,marc=?,encoding=?,z3950random=? where id=?"); $encoding = C4::Context->preference("marcflavour") unless $encoding; # fields used for import results my $imported=0; my $alreadyindb = 0; my $alreadyinfarm = 0; my $notmarcrecord = 0; my $breedingid; for (my $i=0;$i<=$#marcarray;$i++) { my $marcrecord = FixEncoding($marcarray[$i]."\x1D"); my @warnings = $marcrecord->warnings(); if (scalar($marcrecord->fields()) == 0) { $notmarcrecord++; } else { my $oldbiblio = TransformMarcToKoha($dbh,$marcrecord,''); my $isbnlength=10; if($oldbiblio->{isbn}){ $isbnlength = length($oldbiblio->{isbn}); } # if isbn found and biblio does not exist, add it.
