Differences between Database and Schema using different databases?

Question

What are the differences in database terminology between MS SQL and MySQL?

Can a MySQL instance have more than one database? It appears that it can only create diffe

Answer 1

I believe by saying 'schema' for MS SQL you are meaning 'owner'.

From my understand, in MySQL when you do a

SELECT * from world.city;

This query is selecting from the world database the table city.

In MsSQL you will have to do a

SELECT * from world.dbo.city;

Where 'dbo' is the default owner of the table.

To make life easier define the default database by typing

USE world
SELECT * from city;

In MySQL there is no way to declare the owner of the table. ie. 'dbo'.
