    <p>Hello I have two mysql tables one that holds username and password second that holds user information. Here are the tables:</p> <pre><code>CREATE TABLE IF NOT EXISTS `test`.`dbo.users` ( `userId` INT(11) NOT NULL AUTO_INCREMENT , `userUsername` VARCHAR(45) NULL , `userPassword` VARCHAR(45) NULL , `dbo.userProfiles_userProfileId` INT(11) NOT NULL , PRIMARY KEY (`userId`, `dbo.userProfiles_userProfileId`) , INDEX `fk_dbo.users_dbo.userProfiles` (`dbo.userProfiles_userProfileId` ASC) , CONSTRAINT `fk_dbo.users_dbo.userProfiles` FOREIGN KEY (`dbo.userProfiles_userProfileId` ) REFERENCES `test`.`dbo.userProfiles` (`userId` ) ON DELETE CASCADE ON UPDATE CASCADE) ENGINE = InnoDB; CREATE TABLE IF NOT EXISTS `test`.`dbo.userProfiles` ( `userProfileId` INT(11) NOT NULL AUTO_INCREMENT , `userId` INT(11) NOT NULL , `userFirstName` VARCHAR(45) NULL , `userMidleName` VARCHAR(45) NULL , `userLastName` VARCHAR(45) NULL , `userBirthDate` VARCHAR(45) NULL , `userCountry` VARCHAR(45) NULL , `userState` VARCHAR(45) NULL , `userCity` VARCHAR(45) NULL , `userZipCode` VARCHAR(45) NULL , `userPrimaryAddress` VARCHAR(45) NULL , `userSecondaryAddress` VARCHAR(45) NULL , `userThirdAddress` VARCHAR(45) NULL , `userFirstPhone` VARCHAR(45) NULL , `userSecondaryPhone` VARCHAR(45) NULL , `userThirdPhone` VARCHAR(45) NULL , `userFirstEmail` VARCHAR(45) NULL , `userSecondaryEmail` VARCHAR(45) NULL , `userThirdEmail` VARCHAR(45) NULL , `userDescription` VARCHAR(45) NULL , PRIMARY KEY (`userProfileId`, `userId`) ) ENGINE = InnoDB; </code></pre> <p>My problem with this tables is that the fk key doesn't work and I'm not sure why I'm missing something here.. ( I haven't used foreign keys much).</p> <p>Error: </p> <blockquote> <p>Executing SQL script in server</p> <p>ERROR: Error 1005: Can't create table 'test.dbo.users' (errno: 150)</p> </blockquote> <p>Can you please help fixing this so I can use fk on this tables and others? and if you got some time to spare to explain me how fk keys work exactly (using mysql workbench to create them on a diagram then forward engineer). thank you for your help</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
