Hi, I don't get the bug when I run your program on my system, which is Win XP, Perl 5.8.7, ActiveState Build 813, with these DBD::CSV-related module versions:

DBI 1.46
Text::CSV_XS 0.23
SQL::Statement 1.09
DBD::File 0.34
DBD::CSV 0.22
[download]

The output for CSV and for SQLite are identical. And your SQL looks OK to me.
