Why Am I Getting a \'type=MyISAM\' Syntax Error in Hibernate DDL?

Invalid Syntax Error "type=MyISAM" in DDL Generated by Hibernate

The "You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near 'type = MyISAM' at line 1" error in DDL generated by Hibernate typically occurs due to a usage of the deprecated "type" attribute. Here's an analysis and solution:

Ursache

The "type" attribute in SQL is used to specify the storage engine for a table. In MySQL 4.x and earlier, it was common to use "type=MyISAM". However, this attribute was deprecated in MySQL 4.0 and removed in 5.5.

Lösung

To fix this issue, you need to use the correct dialect in your Hibernate configuration. Depending on your version of MariaDB and Hibernate, you need to use one of the following dialects:

• MariaDB:

  • org.hibernate.dialect.MariaDBDialect (for MariaDB 10.0 and earlier)
  • org.hibernate.dialect.MariaDB53Dialect (for MariaDB 10.1 and later)
  • org.hibernate.dialect.MariaDB106Dialect (for MariaDB 10.6 and later)

• MySQL:

  • org.hibernate.dialect.MySQL5Dialect (for MySQL 5.0 and later)
  • org.hibernate.dialect.MySQL55Dialect (for MySQL 5.5 and later)
  • org.hibernate.dialect.MySQL57Dialect (for MySQL 5.7 and later)
  • org.hibernate.dialect.MySQL8Dialect (for MySQL 8.0 and later)

Beispiel

In your Hibernate configuration file, you can specify the correct dialect as follows:

<property name="hibernate.dialect">org.hibernate.dialect.MariaDBDialect</property>

Hinweis

With Hibernate 6, you should use MySQLDialect or MariaDBDialect, as these dialects will automatically configure themselves based on the connected database version.
