NAME

DBIx::Simple::Inject - Injects DBIx::Simple methods into DBI

SYNOPSIS

use DBI;
my $dbh = DBI->connect(
    'dbi:SQLite:dbname=:memory:', '', '', {
        RootClass          => 'DBIx::Simple::Inject',
        RaiseError         => 1,
        PrintError         => 0,
        ShowErrorStatement => 1,
    }
);

# of course can use dbh methods,
$dbh->do('create table users (id, name)');

# and also can use DBIx::Simple methods!
my $row = $dbh->query('select * from users where id = ?', 123)->hash;
my $res = $dbh->insert(users => {
    name => "John",
});

DESCRIPTION

DBIx::Simple::Inject is-a DBI::db. This module injects DBIx::Simple power into DBI itself. So you can use this module directly or via "RootClass".

use DBIx::Simple::Inject;
my $dbh = DBIx::Simple::Inject->connect( ... );

or

use DBI;
my $dbh = DBI->connect( ..., {
    RootClass => 'DBIx::Simple::Inject',
});

This is useful when you use several modules (like DBIx::Connector) that take same as DBI's connect info.

ATTRIBUTE

private_dbixsimple

You can set or access DBIx::Simple's property using "private_dbixsimple" attribute.

my $db = DBI->connect(
    'dbi:...',
    'user',
    'pass',
    {
        RootClass  => 'DBIx::Simple::Inject',
        RaiseError => 1,
        private_dbixsimple => {
            lc_columns      => 0,
            keep_statements => 20,
            result_class    => 'MyApp::Result',
            abstract        => 'SQL::Maker',
        },
    },
);

abstract

For convenience, abstract can take some module names. Supported module names are as follows:

SQL::Abstract
SQL::Abstract::Limit
SQL::Maker

You can also set callback for your own modules as follows.

my $db = DBI->connect(
    ...,
    {
        RootClass => 'DBIx::Simple::Inject',
        private_dbixsimple => {
            abstract => sub {
                my $dbh = shift;
                My::SQL::Generator->new(driver => $dbh->{Driver}{Name});
            },
        },
    },
);

INJECT METHODS

You can use the following methods from DBIx::Simple in addition to all DBI database handle methods.

$dbh->query(), $dbh->select(), $dbh->insert(), $dbh->update(), $dbh->delete(), $dbh->iquery(), $dbh->error(), $dbh->begin()

Note: Besides these, DBIx::Simple provides commit(), rollback() and func(), etc. DBI database handles already provides these methods.

$dbh->lc_columns(), $dbh->keep_statements(), $dbh->result_class(), $dbh->abstract()

These are accessor methods to DBIx::Simple properties.

ANOTHER DBIx ?

Yes.

OK I know that DBIx namespace is hodgepodge. Several authors should know that DBI itself has a lot of useful features already (like "Callbacks").

However, if you don't want ORM but want result set object (blessed result), I think DBIx::Simple makes great success. The module has nice API.

Some useful CPAN modules (that knows DBI's true power) takes $dbh or same arguments as DBI->connect(). That's why I made this module.
