Author: Emmanuel Duchastenier <emmanuel.duchastenier(a)bonitasoft.com&gt; Date: 2021-04-30 (Fri, 30 Apr 2021) Changed paths: M hibernate-core/src/main/java/org/hibernate/tool/schema/internal/AbstractSchemaMigrator.java A hibernate-core/src/test/java/org/hibernate/tool/schema/internal/AbstractSchemaMigratorTest.java Log Message: ----------- HHH-13779 (5.4) - Foreign key schema migrator should be case-insensitive This avoids re-creating existing foreign keys with a different name, after migrating from Hibernate 4 to Hibernate 5 (as implicit naming convention has changed). Actually, some RDBMS allow it (PostgreSQL, MySQL, MS SQL Server, ...) and duplicate the same key, whereas others (Oracle, ...) do not allow it and Schema update fails. This fix ignores the case of the table and column name when checking if a equivalent Foreign Key already exists (whatever its name) Closes https://hibernate.atlassian.net/browse/HHH-13779
