GenerationTarget encountered exception accepting command : Error executing DDL via JDBC Statement

Question

I am a novice in hibernate world and facing,

WARN: GenerationTarget encountered exception accepting command : Error executing DDL via JDBC Statement org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL via JDBC Statement 

exception while I run my stand-alone programe in hibernate 5.2.9 version. But in hibernate 4 version all my code runs well. I looked for many questions and solve but not working answer i got.

Configuration file

hibernate.cfg.xml      <hibernate-configuration>       <session-factory>         <property name="hibernate.dialect">org.hibernate.dialect.MySQLDialect</property>         <property name="hibernate.connection.driver_class">com.mysql.jdbc.Driver</property>         <property name="hibernate.connection.url">jdbc:mysql://localhost:3306/test</property>         <property name="hibernate.connection.username">root</property>         <property name="hibernate.connection.password">admin</property>         <property name="hibernate.connection.pool_size">20</property>         <property name="hibernate.show_sql">true</property>         <property name="hibernate.hbm2ddl.auto">create</property>         <mapping class="com.test.hibernate14417.MyTable"></mapping>       </session-factory>     </hibernate-configuration>

Answer 1

You should try a different dialects likeorg.hibernate.dialect.MySQL5Dialect OR org.hibernate.dialect.MySQLMyISAMDialect OR org.hibernate.dialect.MySQLInnoDBDialect to see which one works for you.

All in all , your current dialect is generating , type=MyISAM while it should be , ENGINE=MyISAM in create table query.

mysql error 'TYPE=MyISAM'

You should read this too , Why do I need to configure the SQL dialect of a data source?

Your logs say that this query was tried to be executed , create table MyTable (id integer not null, name varchar(255), primary key (id)) type=MyISAM so you should try to execute that query directly on mysql command prompt to see if that works for your MySQL version.

Also, in question do specify your MySQL version too.

Hope it helps !!

Answer 2

You are using an updated version of MySQL but using and old dialect

Use either,

<property name="hibernate.dialect">org.hibernate.dialect.MySQL5Dialect</property> 

OR

<property name="hibernate.dialect">org.hibernate.dialect.MySQL8Dialect</property> 

in the hibernate.cfg.xml file.

This prevents you from getting dialect issues.
