	/**
	 * MySQL does support the {@code create schema} command, but
	 * it's a synonym for {@code create database}. Hibernate has
	 * always treated a MySQL database as a
	 * {@linkplain #canCreateCatalog catalog}, which is consistent
	 * with how the JDBC driver itself views the situation, since
	 * {@link DatabaseMetaData#supportsSchemasInDataManipulation()}
	 * returns {@code false} on MySQL.

1. Use catalog-based schema management for MySQL.
2. Create/drop databases manually with native DDL.

When it happens

Trigger: Triggered when the application calls a Hibernate dialect feature that the configured database dialect cannot provide: MySQL does not support dropping creating/dropping schemas in the JDBC sense.

Common situations: Common when running against a database whose dialect lacks this capability, when a mapping or HQL/Criteria query requests unsupported functionality, or when the wrong dialect is configured for the database in use.
