There are two ways to create SCHEMA: LearningSQL

Using SQL Plus
Using visual tools.

Create SCHEMA LearningSQL using SQL Plus

Run 2 commands:

-- Create Schema named learningsql,  password 1234
Create user learningsql identified by 1234;

-- For learning purposes:
-- Grant highest privilege DBA (DB Admin) for the newly created user.
grant dba to learningsql;

Connect to the newly created SCHEMA:

-- Connect to Schema
-- Syntax: connect <user>/<pass>@<sid>

connect learningsql/1234@db11g;

Run Script:

-- Run Script file in SQL Plus

@F:\LEARNING_SQL\LearningSQL-Oracle-Script.sql

Script run successfully:

Create SCHEMA LearningSQL using visual tool

On the visual tools (Here I use PL/SQL Developer), connected to the user with DBA authority (for example: system).

Execute script to create schema: learningsql.

-- Create schema named learningsql

Create user learningsql identified by 1234;

grant dba to learningsql;

Connect to Schema you just created:

Copy content of LearningSQL-Oracle-Script.sql into PL/SQL Developer and execute.

Create Schema success.
