363 | =head2 source_bind_attributes |
364 | |
365 | Handle LOB types in Oracle. Under a certain size (4k?), you can get away |
366 | with the driver assuming your input is the deprecated LONG type if you |
367 | encode it as a hex string. That ain't gonna fly at larger values, where |
368 | you'll discover you have to do what this does. |
369 | |
370 | This method had to be overridden because we need to set ora_field to the |
371 | actual column, and that isn't passed to the call (provided by Storage) to |
372 | bind_attribute_by_data_type. |
373 | |
374 | According to L<DBD::Oracle>, the ora_field isn't always necessary, but |
375 | adding it doesn't hurt, and will save your bacon if you're modifying a |
376 | table with more than one LOB column. |

430 | |
431 | L<DBIx::Class> uses L<DBIx::Class::Relationship> names as table aliases in |

434 | Unfortunately, Oracle doesn't support identifiers over 30 chars in length, so |
af0edca1 |
435 | the L<DBIx::Class::Relationship> name is shortened and appended with half of an |
