Holger Bach ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=642158a... ) *created* an issue Hibernate ORM ( https://hibernate.atlassian.net/browse/HHH?atlOrigin=eyJpIjoiMjhlNWZiMmY2... ) / Bug ( https://hibernate.atlassian.net/browse/HHH-16379?atlOrigin=eyJpIjoiMjhlNW... ) HHH-16379 ( https://hibernate.atlassian.net/browse/HHH-16379?atlOrigin=eyJpIjoiMjhlNW... ) @DynamicUpdate and 'enableDirtyTracking=true' leads to wrong update statement ( https://hibernate.atlassian.net/browse/HHH-16379?atlOrigin=eyJpIjoiMjhlNW... ) Issue Type: Bug Affects Versions: 6.0.2, 6.1.7 Assignee: Unassigned Components: hibernate-orm-modules Created: 27/Mar/2023 03:28 AM Environment: Java 17 Priority: Major Reporter: Holger Bach ( https://hibernate.atlassian.net/secure/ViewProfile.jspa?accountId=642158a... ) When updating an derived entity containing several field, not all changed fields will be updated Having a base entity containing two fields named *checksum* and *variantName* and a derived entity containing one field named *fileSize*. Create an database entry, FileVersion version = new FileVersion(); version.setId("1"); version.setFileSize(100L); version.setCheckSumMD5("ABCDEF"); version.setVariantName("A"); change all fields of the existing database entry (see testcase *testWithDynamicUpdate* ) version.setCheckSumMD5("XXXXXXXX"); version.setVariantName("B"); version.setFileSize(200L); The following update statement will be created Hibernate: update Versionen set CHECKSUM=?, FILESIZE=? where VERS_NUMMER=? Only *checksum* and *fileSize* will be updated, but not the field *variantName*. Problem occurs in file *AbstractEntityPersister* in function *resolveDirtyAttributeIndexes*. ch The dirty fields will be sorted bei name Arrays.sort( attributeNames ); attributeName = {checkSum, fileSize, variantName} In the for loop the fields in *attributeNames* will be compared to the array *attributeMappings* , which contains the mapping informations according to the annotations. *attributeMappings* has the following order: attributeMappings = {AbstarctVersion.checksum, AbstractVersion.variantName, FileVersion.fileSize} The for loop does only recognize the fields *checksum* and *fileSize. variantName* will not be processed.
