Overview
On DreamHost Shared MySQL and MySQL VPS servers, some of the SQL commands are not available for scripting nor in phpMyAdmin. Their functionality is available instead through the DreamHost control panel. These include:
- CREATE DATABASE
- GRANT
- REVOKE
Additionally, some SQL objects are not available or supported on DreamHost Shared MySQL servers. These include:
- Functions
- Triggers
Functions and triggers are available on MySQL VPS servers. They're also available on Dedicated servers with MySQL running locally.
A database will be created using character set utf8mb3 and collation utf8mb3_general_ci.
