Question

Can we create multiple schemas for a particular user? I am currently logged in as X/Y user and when I tried creating a schema using create schema authorization sample_schema, I got the error the schema name is missing or is incorrect in an authorization clause of a create schema statement. I do know that a default schema X would have been created.

Answer 1

CREATE SCHEMA in Oracle does – contrary to its name – not create a new schema.

It is merely a shorthand to create several tables in a single statement.

Quote from the manual:

Use the CREATE SCHEMA statement to create multiple tables and views and perform multiple grants in your own schema in a single transaction

and further down the explanation on what the “schema” name parameter is:

The schema name must be the same as your Oracle Database username.
