The table definition: CREATE TABLE ch_msg (iseq INTEGER PRIMARY KEY AUTOINCREMENT, ch, seq ique (ch,seq,sig)); A one-liner-demonstration of violated unique constraints: perl -MDBI -e 'my $dbh = DBI->connect("dbi:SQLite:dbname=phrankoi.db my $seq = $dbh->selectall_arrayref("SELECT ch, seq, sig FROM ch_msg" print join "\n", map join (", ", @$_), @$seq'; --OUTPUT-- Music, 0, Muchu Music, 1, Muchu Music, 15, anonymous Music, 16, phrankoi Music, 17, phrankoi uEDCS dev., 60, phrankoi uEDCS dev., 61, phrankoi uEDCS dev., 62, Muchu uEDCS dev., 62, anonymous uEDCS dev., 63, Muchu uEDCS dev., 64, Phrankoi uEDCS dev., 64, Phrankoi uEDCS dev., 65, Muchu uEDCS dev., 66, Muchu uEDCS dev., 67, Phrankoi uEDCS dev., 67, Phrankoi uEDCS dev., 68, Muchu uEDCS dev., 69, Phrankoi uEDCS dev., 69, Phrankoi uEDCS dev., 70, Muchu uEDCS dev., 71, Phrankoi uEDCS dev., 72, Phrankoi uEDCS dev., 72, Phranko As you can see there're several unique constraint voilations.... uname -a: Linux OLDLAPTOP 2.4.27-3-386 #1 Wed Dec 6 00:38:33 UTC 200 inux perl -v: This is perl, v5.8.8 built for i486-linux-gnu-thread-multi perl -MDBI -e 'my $dbh =:DBI->connect("dbi:SQLite:dbname=phrankoi.db print $dbh->{sqlite_version}': 3.3.8 How I managed to make them: When using multiple SQLite database handles simultaneously, violated unique constraints "caused" by threads/processes inserting the same thing are simply ignored. Maybe it's not the DBD but sqlite itself. At least I have to execute the checks manually when not being able t only have one dbh open at a time. Cheers! /PhrankoiX

I don't see any unique constraints on that table definition, and if it's somehow getting into SQLite, I can only assume it's the databases problem. Without more information, there's nothing I can do, so making resolved.
