Question

I am using embedded Apache Derby database for JUnit tests. I have some JPA entities. There are entities containing columns like this:

@Column(nullable = false)
private String rawResults;

It all works with embedded Derby, until I got tired of replacing TEXT into LONGTEXT in the queries generated by openjpa-maven-plugin, so I made that column like this:

@Column(nullable = false, columnDefinition = "LONGTEXT")
private String rawResults;

Now openjpa-maven-plugin is generating LONGTEXT instead of TEXT. But this only works while I am skipping my tests.

Then I run my tests and Derby takes place so everything fails with the errors like this:

org.apache.openjpa.lib.jdbc.ReportingSQLException: TYPE 'LONGTEXT' does not exist. {stmnt 23146419 CREATE TABLE Assessment -- Assessment_JpaImpl

I am using Derby 10.9.1.0 and I as far as I understand it does not support columnDefinition = "LONGTEXT". Is this right? Or I need to set up some configuration that make derby support this attribute?

Here are the Derby datatypes: http://db.apache.org/derby/docs/10.9/ref/crefsqlj31068.html#crefsqlj31068
