No dice. Still getting unwanted/duplicate fields. So you have the full benefit of coding stylings, see below:

$strInsert="";
$strFields="";
$strVals="";

my @ioTagList = qw(ObjectName DateCreated By-line By-lineTitle City Province-State
Country-PrimaryLocationName Headline Credit Source Caption-Abstract Writer-Editor
OriginalTransmissionReference Category);
my $exifTool = new Image::ExifTool;
$info = $exifTool-)ImageInfo($imgPath, \@ioTagList, {Group =) 'IPTC'});
foreach (sort keys %$info) {
my $val = $$info{$_};
if (ref $val eq 'ARRAY') {
$val = join(', ', @$val);
} elsif (ref $val eq 'SCALAR') {
$val = '(Binary data)';
}
$strFields = $strFields.$_.",";
$strVals = $strVals."'".$val."',";
$strInsert = "insert into table (".substr($strFields, 0, length($strFields)-1).") values
(".substr($strVals, 0, length($strVals)-1).")";
}
print "\n\n$strInsert\n";
$exifTool='';

result:
insert into table (ApplicationRecordVersion,By-line,Caption-Abstract,Category,Category
(1),City,City (1),CopyrightNotice,Credit,Credit (1),DateCreated,DateCreated
(1),Headline,Headline (1),Keywords,ObjectName,Source,Source (1),SupplementalCategories
