=head2 Database Handle Attributes
=over 4
=item sqlite_version
Returns the version of the SQLite library which DBD::SQLite is using,
e.g., "2.8.0". Can only be read.
=item unicode
If set to a true value, DBD::SQLite will turn the UTF-8 flag on for all text
strings coming out of the database. For more details on the UTF-8 flag see
L<perlunicode>. The default is for the UTF-8 flag to be turned off.
Also note that due to some bizareness in SQLite's type system (see
http://www.sqlite.org/datatype3.html), if you want to retain
blob-style behavior for B<some> columns under C<< $dbh->{unicode} = 1
>> (say, to store images in the database), you have to state so
explicitely using the 3-argument form of L<DBI/bind_param> when doing
updates:
use DBI qw(:sql_types);
$dbh->{unicode} = 1;
my $sth = $dbh->prepare
("INSERT INTO mytable (blobcolumn) VALUES (?)");
$sth->bind_param(1, $binary_data, SQL_BLOB); # binary_data will
# be stored as-is.
Defining the column type as BLOB in the DDL is B<not> sufficient.

=head1 DRIVER PRIVATE METHODS
lib/DBD/SQLite.pm view on Meta::CPAN
Collations C<binary> and C<nocase> are builtin within Sqlite.
Collations C<perl> and C<perllocale> are builtin within
the C<DBD::SQLite> driver, and correspond to the
Perl C<cmp> operator with or without the L<locale> pragma;
so you can write for example
CREATE TABLE foo(txt1 COLLATE perl,
txt2 COLLATE perllocale,
txt3 COLLATE nocase)
If the attribute C<< $dbh->{unicode} >> is set, strings coming from
the database and passed to the collation function will be properly
tagged with the utf8 flag; but this only works if the
C<unicode> attribute is set B<before> the call to
C<create_collation>. The recommended way to activate unicode
is to set the parameter at connection time :
my $dbh = DBI->connect("dbi:SQLite:dbname=foo", "", "",
{ RaiseError => 1,
unicode => 1} );
=head2 $dbh->func( $n_opcodes, $handler, 'progress_handler' )
This method registers a handler to be invoked
periodically during long running calls to SQLite.
An example use for this interface is to keep a GUI
updated during a large query.
