我们在Intershop DB中注意到,从7.9版本迁移到7.10版本时,备用密钥的索引不会生成为UNIQUE INDEX。这导致所有包含备用键(系统和自定义对象)的表都使用数据库中的NONUNIQUE索引生成。例如:
此外,生成.ddl文件代码(CatalogCategoryLinkPO.dbindex.oracle.ddl):

EXEC staging_ddl.create_index('CATALOGCATEGORYLINK_AV_IE003', 'CATALOGCATEGORYLINK_AV', '(doubleValue)', :table_space, 'NONUNIQUE', :recreate_indexes);
当我们尝试为自己的自定义实现对象创建备用密钥时,会发生同样的事情。例如,这是.edl代码段:
orm class A1PromotionBenefitPO extends PersistentObjectPO implements A1PromotionBenefit table "A1PromotionBenefit"
{
/**
* Declare alternate key.
*/
alternate key (promotionUUID, tariffUUID, contractType, contractBinding, domainID);
/**
* Holds link to tariff.
*/
attribute tariffUUID : uuid required searchable;
/**
* Holds link to promotion.
*/
attribute promotionUUID: uuid required;
....
...
这是生成的.ddl文件(A1PromotionBenefitPO.dbindex.oracle.ddl):
/*
=============================================================================
File: A1PromotionBenefitPO.dbindex.oracle.ddl

如您所见,备用键索引A1PROMOTIONBENEFIT_AK001生成为NONUNIQUE。
你知道为什么会这样吗?我们的代码依赖于备用密钥,因此我们不希望从我们的orm模型中完全删除备用密钥。
这似乎是7.10引入的错误。您应该使用Intershop支持提交错误报告。
作为一种解决方法,您当然可以更改生成的DDL文件。不确定您是否最终可以更改用作模板的ORMDDL.xpt来生成这些DDL文件。
我在内部创建了一个错误,当您向Intershop支持部门提交错误报告时,请参阅问题IS-26076。通过支持,您将获得状态更新。
