I have installed oracle 10g express edition and I did not find the option to create schema..
Is there a option to create schema in oracle 10g express edition or else I have to install other oracle 10g..?
To create schema which oracle 10g I have to install... what?
You don't need to explicitly create schema, Oracle automatically creates a schema when you create a user (see CREATE USER
documentation).
If you really want, you can use CREATE SCHEMA
statement and issue it through Oracle Express web interface or from SQL prompt.
