Question

In SQL Server we have:

Instance->Database->Schema->Objects (tables etc)

I’m confused what the MySQL equivalents are, specifically “database” and “schema”. From what I can tell it’s something like:

| SQL Server | MySQL    |
|------------|----------|
| Instance   | Instance |
| Database   | Schema   |
| Schema     | N/A      |
| Objects    | Objects  |

How far wrong am I?

Many thanks in advance.

From http://lists.mysql.com/mysql/211616:

In MySQL, the two are equivalent. The keyword DATABASE or DATABASES
can be replaced with SCHEMA or SCHEMAS wherever it appears. Examples:

CREATE DATABASE <=> CREATE SCHEMA

SHOW DATABASES <=> SHOW SCHEMAS

For what it is worth, this is the case in Oracle as well.
