Java – generationtarget encountered an exception to accept the command: error executing DDL through JDBC statement
•
Java
I'm a novice in the hibernate world. In the face of,
WARN: GenerationTarget encountered exception accepting command : Error executing DDL via JDBC Statement org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL via JDBC Statement
I'm in Hibernate 5.2 An exception occurred while running my standalone program in version 9 But in Hibernate 4, my code works well I looked for many problems and solved them, but I didn't get the answers

Solution
You should try to use different dialects, such as org. Org hibernate. dialect. Mysql5dialect or org hibernate. dialect. Mysqlmyisamdialect or org hibernate. dialect. Mysqlinnodbdialect to see which dialect is right for you
To sum up, your current dialect is being generated, type = MyISAM, but should be engine = MyISAM in the create table query
mysql error ‘TYPE=MyISAM’
Why do I need to configure the SQL dialect of a data source?
Your log says that this query is an attempt to execute. Create a table mytable (ID integer not null, primary key (ID)) type = MyISAM, so you should try to execute the query directly at the MySQL command prompt to see if it is applicable to your version of MySQL
In addition, if there is a problem, please specify your version of MySQL
Hope to help you!!
