MySQL中架构/数据库之间的区别

MySQL 中的模式和数据库之间有区别吗?在 SQL Server 中,数据库是与架构相关的更高级别的容器.

Is there a difference between a schema and a database in MySQL? In SQL Server, a database is a higher level container in relation to a schema.

我读到 Create SchemaCreate Database 在 MySQL 中做的事情本质上是一样的,这让我相信模式和数据库是相同对象的不同词.

I read that Create Schema and Create Database do essentially the same thing in MySQL, which leads me to believe that schemas and databases are different words for the same objects.

推荐答案

如MySQL 术语表中所定义:

在 MySQL 中,模式在物理上与数据库同义.您可以在 MySQL SQL 语法中用关键字 SCHEMA 代替 DATABASE,例如使用 CREATE SCHEMA 而不是 CREATE DATABASE>.

In MySQL, physically, a schema is synonymous with a database. You can substitute the keyword SCHEMA instead of DATABASE in MySQL SQL syntax, for example using CREATE SCHEMA instead of CREATE DATABASE.

其他一些数据库产品有所区别.例如,在 Oracle 数据库产品中,模式仅代表数据库的一部分:单个用户拥有的表和其他对象.

Some other database products draw a distinction. For example, in the Oracle Database product, a schema represents only a part of a database: the tables and other objects owned by a single user.
