java - Oracle column name issue -


i have parent-child mapping in hibernate entities connected through table.

the problem column automatically created hibernate in table called "_actions_id". use oracle , says column name "_actions_id" invalid.

it works fine when wrap name "" , execute script manually, there way make hibernate wrap columns "" ?

in example, specified join table, scenarios this

people table: pid | name 1   | albert 2   | bob   telephonenumbers table: tid | tel 1   | 123-456 2   | 456-789 3   | 789-012  join table: pid | tid 1   | 1 1   | 2 2   | 3

i.e. column connects current entity entity in collection in neither current table nor table collection entity. more useful many-to-many mapping, can use onetomany if don't have control on telephonenumbers table example. otherwise should use plain @joincolumn.

the usage of @jointable has been explained many times many websites. see javadoc , this question.
