Why the error 'No database selected'?

Short answer. You did not run USE.

What shows the tables inside?

SHOW TABLES.

Remember

CREATE makes the database
USE selects it

You created a database. So why does My S Q L say no database selected? Create database only makes it. Use school selects it. Now your tables go inside. Create makes it. Use selects it, every login.

This clip is from the full lesson: SQL Data Definition: CREATE DATABASE, CREATE TABLE, ALTER and DROP — 6 minutes, with the tables, the quick answers and the whole lesson in text.
