you should add <input type="hidden" name="num_rows" value="0"> form , update value row count when form submitted.

sql - text truncated using perl DBI insert -

the problem dbi 's insert leaves long string truncated when inserting ms sql server. here codes: my $insert = $dbh->prepare("insert my_table (field_1, field_2) values (?, ?)"); $insert->execute($value_1, $value_2); where field_2 has data type of varchar(100) , $value_2 text string of 90 characters spaces no other special characters. after statement executed, no error raised, checked database , apparently actual inserted $value_2 truncated @ 80th character, in middle of regular english word (i.e. not special character). i've tried alter data type of field_2 varchar(150) , text . i've used $dbh->quote($value_2) in place of $value_2 . didn't help. why happening? should do? thx!! if using freetds bug identified in freetds mailing list. see freetds silently truncating text/varchar/etc fields 80 characters , http://lists.ibiblio.org/pipermail/freetds/2011q2/026943.html , http://lists.ibiblio.org/pipermail/freetds/2011q2/026...
