I have a main table, called "Immobili", which has a Primary Key composed by four columns: (Comune, Via, Civico, Immobile). Now, I also have three other tables, wich have the same primary key (Comune, Via, Civico, Immobile), but these fields are also referenced to the table Immobili. First question: Can I make a Primary mysql can't create table errno 150 foreign key Key that is also a Foreign Key? Second Question: When I try to export the changes it says: Executing SQL script in server # ERROR: Error 1005: Can't create table 'dbimmobili.condoni' (errno: 150) CREATE TABLE IF NOT EXISTS `dbimmobili`.`Condoni` ( `ComuneImmobile` VARCHAR(50) NOT NULL , `ViaImmobile` VARCHAR(50) NOT NULL , `CivicoImmobile` VARCHAR(5) NOT NULL , `InternoImmobile` VARCHAR(3) NOT NULL , `ProtocolloNumero` VARCHAR(15) NULL , `DataRichiestaSanatoria` DATE NULL , `DataSanatoria` DATE NULL , `SullePartiEsclusive` TINYINT(1) NULL , `SullePartiComuni` TINYINT(1) NULL , `OblazioneInEuro` DOUBLE NULL , `TecnicoOblazione` VARCHAR(45) NULL , `TelefonoTecnico` VARCHAR(15) NULL , INDEX `ComuneImmobile` (`ComuneImmobile` ASC) , INDEX `ViaImmobile` (`ViaImmobile` ASC) , INDEX `CivicoImmobile` (`CivicoImmobile` ASC) , INDEX `InternoImmobile` (`InternoImmobile` ASC) , PRIMARY KEY (`ComuneImmobile`, `ViaImmobile`, `CivicoImmobile`, `InternoImmobile`) , CONSTRAINT `ComuneImmobile` FOREIGN KEY (`ComuneImmobile` ) REFERENCES `dbimmobili`.`Immobile` (`ComuneImmobile` ) ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT `ViaImmobile` FOREIGN KEY (`ViaImmobile` ) REFERENCES `dbimmobili`.`Immobile` (`ViaImmobile` ) ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT `CivicoImmobile` FOREIGN KEY (`CivicoImmobile` ) REFERENCES `dbimmobili`.`Immobile` (`CivicoImmobile` ) ON DELETE CASCADE ON UPDATE CASCADE, CONSTRAINT `InternoImmobile` FOREIGN KEY (`InternoImmobile` ) REFERENCES `dbimmobili`.`Immobile` (`InternoImmobile` ) ON DELETE CASCADE ON UPDATE CASCADE ) ENGINE = InnoDB Showing the Engine Status: Error in foreign key constraint of table dbimmobili/valutazionimercato: Ca

Errno 150 Mysql Foreign Key
it only takes a minute: Sign up Error Code: 1005. Can't create table '…' (errno: 150) up vote 74 down vote favorite 30 I searched for a solution to this problem on internet and checked the SO questions but http://stackoverflow.com/questions/4063141/mysql-foreign-key-error-1005-errno-150 no solution worked for my case. I want to create a foreign key from table sira_no to metal_kod. ALTER TABLE sira_no ADD CONSTRAINT METAL_KODU FOREIGN KEY(METAL_KODU) REFERENCES metal_kod(METAL_KODU) ON DELETE SET NULL ON UPDATE SET NULL ; This script returns: Error Code: 1005. Can't create table 'ebs.#sql-f48_1a3' (errno: 150) I tried adding index to the referenced table: CREATE INDEX METAL_KODU_INDEX ON metal_kod (METAL_KODU); I checked METAL_KODU on both tables (charset and collation). But couldn't find a solution to this http://stackoverflow.com/questions/9018584/error-code-1005-cant-create-table-errno-150 problem. Does anyone have any idea? Thanks in advance.

FK-linked fields must match definitions exactly. Some Known causes may be : The two key fields type and/or size doesn’t match exactly. For example, if one is INT(10) the key field needs to be INT(10) as well and not INT(11) or TINYINT. You may want to confirm the field size using SHOW CREATE TABLE because Query Browser will sometimes visually show just INTEGER for both INT(10) and INT(11). You should also check that one is not SIGNED and the other is UNSIGNED. They both need to be exactly the same. One of the key field that you are trying to referen

MySQL errno 150 ERROR 1005 (HY000): Can't create table 'table' (errno: 150) ERROR 1025 (HY000): Error on rename of 'table' to 'newtable' (errno: 150) Causes and Solutions for errno 150 Data Types Don't Match: Click for solutionThe types of the columns have to be the same (usually). This is one of the most common reasons for errno 150. For instance, if the type of the child column is VARCHAR(50), the type of the parent column should be exactly VARCHAR(50) (since they're supposed to hold the same data). For numeric types, if one is UNSIGNED, then both have to be UNSIGNED. They should match exactly!. I have run into circumstances where it has let me create a foreign key where the child column was a VARCHAR(50) and the parent column was a VARCHAR(200). Interestingly, if I tried to do the opposite for the same tables, reference a

I see that in general, there is a bug that innodb can not deal with # in table names. I would argue that that is a different bug since it was talking about tables that the user generates. I have no control over these temporary tables, and therefore no work-around at all. Suggested fix: Make it work. :) Or at least change the temporary table to not use #.
