This might be a weird query but its related to deleting specific details in database.
Bascially I had built a database using a set of files
and after building the database i realized that i didn't need the whole data. i am required to not only delete content of database related to seq2 to seq4 but also delete content related to last 200 bytes in seq1
Basically i am required to retain only first 100 mb of data in seq1.
without going through the whole procedure of rebuilding the db could i delete contents of database corresponding to these requirements.
i know its a little unusal but could some one give a direction.

SQL::Translator::Parser::DBI(3pm) User Contributed Perl Documentation SQL::Translator::Parser::DBI(3pm)NAME
SQL::Translator::Parser::DBI - "parser" for DBI handles
SYNOPSIS
use DBI;
use SQL::Translator;
my $dbh = DBI->connect('dsn', 'user', 'pass',
{
RaiseError => 1,
FetchHashKeyName => 'NAME_lc',
}
);
my $translator = SQL::Translator->new(
parser => 'DBI',
dbh => $dbh,
);
Or:
use SQL::Translator;
my $translator = SQL::Translator->new(
parser => 'DBI',
parser_args => {
dsn => 'dbi:mysql:FOO',
db_user => 'guest',
db_password => 'password',
}
);
DESCRIPTION
This parser accepts an open database handle (or the arguments to create one) and queries the database directly for the information.
The following are acceptable arguments:
o dbh
An open DBI database handle. NB: Be sure to create the database with the "FetchHashKeyName => 'NAME_lc'" option as all the DBI
parsers expect lowercased column names.
o dsn
The DSN to use for connecting to a database.
o db_user
The user name to use for connecting to a database.
o db_password
The password to use for connecting to a database.
There is no need to specify which type of database you are querying as this is determined automatically by inspecting
$dbh->{'Driver'}{'Name'}. If a parser exists for your database, it will be used automatically; if not, the code will fail automatically
(and you can write the parser and contribute it to the project!).
Currently parsers exist for the following databases:
o MySQL
o SQLite
o Sybase
o PostgreSQL (still experimental)
Most of these parsers are able to query the database directly for the structure rather than parsing a text file. For large schemas, this
is probably orders of magnitude faster than traditional parsing (which uses Parse::RecDescent, an amazing module but really quite slow).
Though no Oracle parser currently exists, it would be fairly easy to query an Oracle database directly by using DDL::Oracle to generate a
DDL for the schema and then using the normal Oracle parser on this. Perhaps future versions of SQL::Translator will include the ability to
query Oracle directly and skip the parsing of a text file, too.
