DBD::ODBC works for me with the MS SQL Server ODBC Driver (Windows), the MS SQL Server Native Client (Windows) and the Easysoft SQL Server ODBC Driver (Linux).

use strict; use warnings; use DBI; use Test::More; use Config; open(my $f, "<", "pm_994504.jpg") or die "$!"; binmode($f); my $jpg = do {local $/ = <$f>}; my $h = DBI->connect; $h->{RaiseError} = 1; $h->{PrintError} = 0; { diag("\n"); diag("Perl $Config{PERL_REVISION}.$Config{PERL_VERSION}.$Config{PE +RL_SUBVERSION}\n"); diag("osname=$Config{osname}, osvers=$Config{osvers}, archname=$Co +nfig{archname}\n"); diag("Using DBI $DBI::VERSION\n"); diag("Using DBD::ODBC $DBD::ODBC::VERSION\n"); diag("Using DBMS_NAME " . DBI::neat($h->get_info(17)) . "\n"); diag("Using DBMS_VER " . DBI::neat($h->get_info(18)) . "\n"); my $driver_name = DBI::neat($h->get_info(6)); diag("Using DRIVER_NAME $driver_name\n"); diag("Using DRIVER_VER " . DBI::neat($h->get_info(7)) . "\n"); diag("odbc_has_unicode " . $h->{odbc_has_unicode} . "\n"); } eval { $h->do(q/drop table mje/); }; $h->do(q/create table mje (a varbinary(max), b image)/); my $s = $h->prepare(q/insert into mje values(?,?)/); $s->execute($jpg, $jpg); # you were using pack so here it is with pack as well my $binary = pack("H*", $jpg); $s->execute($binary, $binary); $s = $h->prepare(q/select * from mje/); $s->{LongReadLen} = 800_000; $s->execute; my $r = $s->fetchall_arrayref; is($r->[0][0], $jpg, "jpeg in varbinary column"); is($r->[0][1], $jpg, "jpeg in image column"); is($r->[1][0], $binary, "packed jpeg in varbinary column"); is($r->[1][1], $binary, "packed jpeg in image column"); done_testing;

It did not work with the freeTDS driver I have (I've no idea why). It produced Error converting characters into server's character set. Some character(s) could not be converted (SQL-HY000) at line 35, <$f> line 1.

BTW, just so you know, I maintain DBD::ODBC and I also work for Easysoft.

UPDATE: the second insert was not using $binary and similary with the test at the end.

    If you read the links in my OP, one of them is a link to FreeTDS discussing the problem and another is using FreeTDS with DBD::ODBC. It appears that FreeTDS has issues.

    Thanks for the driver recommendation! I'll try that combination and hopefully get it to work.
