问题 Is the schema for a table and the owner for a table the same in oracle? If not what is the difference? 回答1: As Tom says: You should consider a schema to be the user account and collection of all objects therein as a schema for all intents and purposes. A table created by a user - and therefore owned by that user, as the owner in all_tables for example - forms part of that user's schema. So yes, the owner and schema are the same. Also see this earlier question, which references the same AskTom
