Howdy! Thanks for following up. * Bytebase version: 3.9.1 Community Edition * Database engine: MySQL 8.0.39 The issue happens when synchronizing schemas directly: foreign keys do not appear in the synced schema. Here’s a real example: - Schema from database dump (with FKs): CREATE TABLE `DMNT_ClientData` ( `Id` int NOT NULL AUTO_INCREMENT, `ClientRef` char(50) COLLATE latin1_bin NOT NULL, `Type` char(50) CHARACTER SET latin1 COLLATE latin1_bin NOT NULL, `Value` varchar(1000) COLLATE latin1_bin NOT NULL, `Status` enum('Activated','Archived','Deleted') COLLATE latin1_bin NOT NULL, `CreatedBy` char(50) COLLATE latin1_bin NOT NULL, `Created` timestamp NOT NULL, `ModifiedBy` char(50) COLLATE latin1_bin NOT NULL, `Modified` timestamp NOT NULL, PRIMARY KEY (`Id`), UNIQUE KEY `DMNT_ClientData_UNIQUE` (`ClientRef`,`Type`), KEY `DMNT_ClientData_DMNT_Users_FK` (`CreatedBy`), KEY `DMNT_ClientData_DMNT_Users_FK_1` (`ModifiedBy`), KEY `DMNT_ClientData_DMNT_ClientDataType_FK` (`Type`), CONSTRAINT `DMNT_ClientData_DMNT_ClientDataType_FK` FOREIGN KEY (`Type`) REFERENCES `DMNT_ClientDataTypes` (`Ref`), CONSTRAINT `DMNT_ClientData_DMNT_Clients_FK` FOREIGN KEY (`ClientRef`) REFERENCES `DMNT_Clients` (`Ref`), CONSTRAINT `DMNT_ClientData_DMNT_Users_FK` FOREIGN KEY (`CreatedBy`) REFERENCES `DMNT_Users` (`Ref`), CONSTRAINT `DMNT_ClientData_DMNT_Users_FK_1` FOREIGN KEY (`ModifiedBy`) REFERENCES `DMNT_Users` (`Ref`) ) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=latin1 COLLATE=latin1_bin;
