Re: [eclipselink-dev] bug 326968 - size of compound key of the entity TelephoneNumber exceeds MaxDBs limit
|
Hi Tom, all,
https://bugs.eclipse.org/bugs/show_bug.cgi?id=326968
https://bugs.eclipse.org/bugs/attachment.cgi?id=180245
Sorry for bothering you again but it turned out that the PK sizes of the entities
org.eclipse.persistence.testing.models.jpa.ddlgeneration.CKeyEntityA,
CKeyEntityB and CKeyEntityC
also exceed the limit on MaxDB. This affects three tests in the DDLGenerationJUnitTestSuite:
.testDDLUniqueKeysAsJoinColumns
.testDDLUnidirectionalOneToMany
.testManyToManyWithMultipleJoinColumns
Specifying a length for the PK components solves the issue. Do you have objections to do so?
