Tables for entities with boolean fields not created

问题

i tried to switch a connection pool in GlassFish 4 from MySQL to Derby. I am using Spring-Data-JPA with JPA/Hibernate. The problem is that not all tables are created with the derby pool. The tables for entities which have at least one boolean field are not created.

I found nothing in the log files. :(

My applicationContext.xml:

回答1:

If the problem is only creating boolean columns, try to use @Column to add DDL statement to the Derby database, I know this decrease portability but it will solve the problem. the property is named columnDefinition. http://docs.oracle.com/javaee/6/api/javax/persistence/Column.html

Also I think there need to be something in the log, try to increase the log level.

Okay, i found the solution: I connected to the derby database and executed the command values syscs_util.syscs_get_database_property( 'DataDictionaryVersion' ); The result was 10.1, but version 10.7 is necessary for boolean support. I then renamed the database name in the derby pool inside GlassFish (its by default sun-appserv-samples) and now all tables are created. With the new database the command gave me version 10.9.
