Intershop 7.10代碼生成器備用密鑰生成 - NONUNIQUE

Question

我們在Intershop DB中注意到，從7.9版本遷移到7.10版本時，備用密鑰的索引不會生成為UNIQUE INDEX。 這導致所有包含備用鍵（系統和自定義對象）的表都使用數據庫中的NONUNIQUE索引生成。 例如：

此外，生成.ddl文件代碼（CatalogCategoryLinkPO.dbindex.oracle.ddl）：

/*

VARIABLE recreate_indexes NUMBER;

EXEC :table_space := '&index_tablespace';
EXEC :recreate_indexes := '&recreate_indexes';

PROMPT /* Class com.intershop.beehive.xcs.internal.catalog.CatalogCategoryLinkPO */

EXEC staging_ddl.create_index('CATALOGCATEGORYLINK_FK999', 'CATALOGCATEGORYLINK', '(TARGETCATEGORYID)', :table_space, 'NONUNIQUE', :recreate_indexes);
EXEC staging_ddl.create_index('CATALOGCATEGORYLINK_FK998', 'CATALOGCATEGORYLINK', '(SOURCECATEGORYID)', :table_space, 'NONUNIQUE', :recreate_indexes);


PROMPT -- Foreign key indices (dependencies)
EXEC staging_ddl.create_index('CATALOGCATEGORYLINK_FK997', 'CATALOGCATEGORYLINK', '(DOMAINID)', :table_space, 'NONUNIQUE', :recreate_indexes);


PROMPT -- Inversion Entry key indices
EXEC staging_ddl.create_index('CATALOGCATEGORYLINK_IE001', 'CATALOGCATEGORYLINK', '(TYPECODE)', :table_space, 'NONUNIQUE', :recreate_indexes);
EXEC staging_ddl.create_index('CATALOGCATEGORYLINK_IE002', 'CATALOGCATEGORYLINK', '(SOURCECATEGORYID,TARGETCATEGORYID,DOMAINID,TYPECODE)', :table_space, 'UNIQUE', :recreate_indexes);


PROMPT -- Searchable attribute indices
EXEC staging_ddl.create_index('CATALOGCATEGORYLINK_IE999', 'CATALOGCATEGORYLINK', '(DOMAINID)', :table_space, 'NONUNIQUE', :recreate_indexes);


EXEC staging_ddl.create_index('CATALOGCATEGORYLINK_AK001', 'CATALOGCATEGORYLINK', '(SOURCECATEGORYID,TARGETCATEGORYID,DOMAINID,TYPECODE)', :table_space, 'NONUNIQUE', :recreate_indexes);

PROMPT /* Class com.intershop.beehive.xcs.internal.catalog.CatalogCategoryLinkPOAttributeValue */
PROMPT -- Foreign key indices
EXEC staging_ddl.create_index('CATALOGCATEGORYLINK_AV_FK002', 'CATALOGCATEGORYLINK_AV', '(ownerID)', :table_space, 'NONUNIQUE', :recreate_indexes);

PROMPT -- Inversion Entry key indices
EXEC staging_ddl.create_index('CATALOGCATEGORYLINK_AV_IE002', 'CATALOGCATEGORYLINK_AV', '(intValue)', :table_space, 'NONUNIQUE', :recreate_indexes);
EXEC staging_ddl.create_index('CATALOGCATEGORYLINK_AV_IE003', 'CATALOGCATEGORYLINK_AV', '(doubleValue)', :table_space, 'NONUNIQUE', :recreate_indexes);

當我們嘗試為自己的自定義實現對象創建備用密鑰時，會發生同樣的事情。 例如，這是.edl代碼段：

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;
....
...

這是生成的.ddl文件（A1PromotionBenefitPO.dbindex.oracle.ddl）：

/*
 =============================================================================
 File: A1PromotionBenefitPO.dbindex.oracle.ddl
 Generated by JGen Code Generator from INTERSHOP Communications AG.
 =============================================================================

EXEC staging_ddl.create_index('A1PROMOTIONBENEFIT_FK999', 'A1PROMOTIONBENEFIT', '(DISCOUNTUUID)', :table_space, 'NONUNIQUE', :recreate_indexes);
EXEC staging_ddl.create_index('A1PROMOTIONBENEFIT_FK998', 'A1PROMOTIONBENEFIT', '(PROMOTIONUUID)', :table_space, 'NONUNIQUE', :recreate_indexes);


PROMPT -- Foreign key indices (dependencies)
EXEC staging_ddl.create_index('A1PROMOTIONBENEFIT_FK997', 'A1PROMOTIONBENEFIT', '(DOMAINID)', :table_space, 'NONUNIQUE', :recreate_indexes);
EXEC staging_ddl.create_index('A1PROMOTIONBENEFIT_FK996', 'A1PROMOTIONBENEFIT', '(TARIFFUUID)', :table_space, 'NONUNIQUE', :recreate_indexes);


PROMPT -- Inversion Entry key indices
EXEC staging_ddl.create_index('A1PROMOTIONBENEFIT_IE001', 'A1PROMOTIONBENEFIT', '(PROMOTIONUUID,TARIFFUUID,CONTRACTTYPE,CONTRACTBINDING,DOMAINID)', :table_space, 'UNIQUE', :recreate_indexes);

EXEC staging_ddl.create_index('A1PROMOTIONBENEFIT_AK001', 'A1PROMOTIONBENEFIT', '(PROMOTIONUUID,TARIFFUUID,CONTRACTTYPE,CONTRACTBINDING,DOMAINID)', :table_space, 'NONUNIQUE', :recreate_indexes);

如您所見，備用鍵索引A1PROMOTIONBENEFIT_AK001生成為NONUNIQUE。

你知道為什么會這樣嗎？ 我們的代碼依賴於備用密鑰，因此我們不希望從我們的orm模型中完全刪除備用密鑰。

這似乎是7.10引入的錯誤。 您應該使用Intershop支持提交錯誤報告。

作為一種解決方法，您當然可以更改生成的DDL文件。 不確定您是否最終可以更改用作模板的ORMDDL.xpt來生成這些DDL文件。

我在內部創建了一個錯誤，當您向Intershop支持部門提交錯誤報告時，請參閱問題IS-26076。 通過支持，您將獲得狀態更新。
