the original title was "springdata jpa uses @ ElementCollection to report an error" Table doesn"t exists ". Later, I patiently read all the error messages and found that the source of the error was that the sql syntax generated by hibernate was incompatible with my mysql. The new error message is as follows:

this is the sql:
Hibernate: create table bill_records of hibernate table creation (bill_id bigint not null, records varchar (255), index integer not null, primary key (bill_id, index)) engine=MyISAM
- I wrote an entity class with a collection attribute, so I mapped it to a table with @ ElementCollection annotation, but reported an error in the process of using it, and the database did not create that table. Let the boss see why.
- the code is shown in figure
3.hibernate
- the following is the error message
org.hibernate.tool.schema.spi.CommandAcceptanceException: Error executing DDL via JDBC Statement
