Subclassed DBI connection handle with added convenience features. In addition
to the features added by Dancer::Plugin::Database::Core::Handle
, this module
adds a return value to quick_insert
if requested.
Set this Handle in you app config:
plugins:
Database:
driver: 'Pg'
database: 'postgres'
host: '172.17.0.3'
port: 5432
username: 'postgres'
password: 'pwd'
dbi_params:
RaiseError: 1
AutoCommit: 1
log_queries: 1
handle_class: 'DBIx::Core::Handle::ReturnValue'
Use it in your Dancer app:
my $id = database->quick_insert($tablename, \%data, { last_insert_id => [ ... ] });
my $uuid = database->quick_insert('mytable', { foo => 'Bar', baz => 5 }, { returning => 'entry_uuid' });
A DBIx::Core::Handle::ReturnValue
object is a subclassed DBI::db
database handle, with the following added convenience methods in addition to
those added by Dancer::Plugin::Database::Core::Handle
:
database->quick_insert('mytable', { foo => 'Bar', baz => 5 }, { returning => 'id' });
This is a PostgreSQL-specific functionality which is very flexible and easy. It is especially useful when you use UUIDs as primary keys which are not returned by the normal last_insert_id
functionality.
database->quick_insert('mytable', { foo => 'Bar', baz => 5 }, { last_insert_id => [ .. ] });
The last_insert_id
variant calls the DBI method last_insert_id
with the parameters given in the array ref above. It depends on your database driver what needs to be filled in there.
If no third parameter is given, the call acts like defined by
Dancer::Plugin::Database::Core::Handle
After installing, you can find documentation for this module with the perldoc command.
