You might want to look at DBI with DBD::ODBC. Many database do not allow the insertion of text and blob fields with straight insert statements (Informix, for one). In DBI one can use placeholders when inserting to do so. Placeholder will also automatically quote fields properly, removing another hassle.
Assuming (and in all fairness I have not used it) that DBD::ODBC is as complete a driver as the others I have used (mysql, oracle, informix), you should find that it does what you want.
It would lokk roughly like:

   my $dbh = DBI->connect(connect params...) or die "connect failed: $
+DBI::errstr";
   $dbh->do("insert into table (a,b,c) values(?,?,?)",{},
            3,$x,$long_text_field_or_blob_data) or die "do failed: $DB
+I::errstr";

All the quoting and blob magic needed is done by the DBD driver.
