支持的 Azure Database for MySQL 服务器版本Supported Azure Database for MySQL server versions

使用 InnoDB 引擎通过 MySQL Community Edition 开发 Azure Database for MySQL。Azure Database for MySQL has been developed from MySQL Community Edition, using the InnoDB engine.

MySQL 使用 X.Y.Z 命名方案。MySQL uses the X.Y.Z naming scheme. X 是主版本,Y 是次版本,Z 是 bug 修复版本。X is the major version, Y is the minor version, and Z is the bug fix release. 有关方案的详细信息,请参阅 MySQL 文档For more information about the scheme, see the MySQL documentation.

备注

在服务中,网关用于将连接重定向到服务器实例。In the service, a gateway is used to redirect the connections to server instances. 建立连接后,MySQL 客户端显示网关中设置的 MySQL 版本,而不是 MySQL 服务器实例上运行的实际版本。After the connection is established, the MySQL client displays the version of MySQL set in the gateway, not the actual version running on your MySQL server instance. 若要确定 MySQL 服务器实例的版本,可在 MySQL 提示符处使用 SELECT VERSION(); 命令。To determine the version of your MySQL server instance, use the SELECT VERSION(); command at the MySQL prompt.
