DBIx::Class::Storage::DBI::Oracle::Generic - Automatic primary key class for Oracle
# In your table classes __PACKAGE__->load_components(qw/PK::Auto Core/); __PACKAGE__->add_columns({ id => { sequence => 'mysequence', auto_nextval => 1 } }); __PACKAGE__->set_primary_key('id'); __PACKAGE__->sequence('mysequence');
This class implements autoincrements for Oracle.
Returns the sequence name for an autoincrement column
This wraps the superclass version of this method to force table names to uppercase
This sets the proper DateTime::Format module for use with DBIx::Class::InflateColumn::DateTime.
Used as:
on_connect_call => 'datetime_setup'
In "connect_info" in DBIx::Class::Storage::DBI to set the session nls date, and timestamp values for use with DBIx::Class::InflateColumn::DateTime and the necessary environment variables for DateTime::Format::Oracle, which is used by it.
Maximum allowable precision is used, unless the environment variables have already been set.
These are the defaults used:
$ENV{NLS_DATE_FORMAT} ||= 'YYYY-MM-DD HH24:MI:SS'; $ENV{NLS_TIMESTAMP_FORMAT} ||= 'YYYY-MM-DD HH24:MI:SS.FF'; $ENV{NLS_TIMESTAMP_TZ_FORMAT} ||= 'YYYY-MM-DD HH24:MI:SS.FF TZHTZM';
To get more than second precision with DBIx::Class::InflateColumn::DateTime for your timestamps, use something like this:
use Time::HiRes 'time'; my $ts = DateTime->from_epoch(epoch => time);
Handle LOB types in Oracle. Under a certain size (4k?), you can get away with the driver assuming your input is the deprecated LONG type if you encode it as a hex string. That ain't gonna fly at larger values, where you'll discover you have to do what this does.
This method had to be overridden because we need to set ora_field to the actual column, and that isn't passed to the call (provided by Storage) to bind_attribute_by_data_type.
According to DBD::Oracle, the ora_field isn't always necessary, but adding it doesn't hurt, and will save your bacon if you're modifying a table with more than one LOB column.
