NAME

DBIO::Storage::DBI::UniqueIdentifier - Storage component for RDBMSes supporting GUID types

VERSION

version 0.900000

DESCRIPTION

This is a storage component for databases that support GUID types such as uniqueidentifier, uniqueidentifierstr or guid.

GUIDs are generated automatically for PK columns with a supported data_type, as well as non-PK with auto_nextval set.

ATTRIBUTES

new_guid

The composing class must set new_guid to the method used to generate a new GUID. It can also set it to undef, in which case the user is required to set it, or a runtime error will be thrown. It can be:

string

In which case it is used as the name of database function to create a new GUID,

coderef

In which case the coderef should return a string GUID, using Data::GUID, or whatever GUID generation method you prefer. It is passed the $self DBIO::Storage reference as a parameter.

For example:

$schema->storage->new_guid(sub { Data::GUID->new->as_string });

METHODS

_is_guid_type

Internal helper returning true when a column data_type matches a known GUID datatype.

_prefetch_autovalues

Populate missing GUID values before insert for GUID PK columns and GUID auto_nextval columns.
