    <p>Been looking at this for two days and am at a loss as to what this means. I know it means "exactly what it says" but I don't know how to fix it. Can someone explain it to me in layman's terms and help me out?</p> <pre><code>ERROR: Error 1452: Cannot add or update a child row: a foreign key constraint fails (`sls11n`.`dependent`, CONSTRAINT `fk_dependent_employee1` FOREIGN KEY (`emp_id`) REFERENCES `employee` (`emp_id`) ON DELETE NO ACTION ON UPDATE NO ACTION) INSERT INTO `sls11n`.`dependent` (`dep_id`, `emp_id`, `dep_ssn`, `dep_fname`, `dep_lname`, `dep_street`, `dep_city`, `dep_state`, `dep_zip`, `dep_phone`, `dep_email`, `dep_notes`) VALUES (NULL, 13, 123456789, 'Gary', 'Hart', 'West St', 'San Diego', 'CA', '23424', '1234567890', 'garyhart@me.com', NULL) </code></pre> <p>Here's the script that I believe is relevant:</p> <pre><code>-- ----------------------------------------------------- -- Table `sls11n`.`employee` -- ----------------------------------------------------- DROP TABLE IF EXISTS `sls11n`.`employee` ; SHOW WARNINGS; CREATE TABLE IF NOT EXISTS `sls11n`.`employee` ( `emp_id` TINYINT UNSIGNED NOT NULL AUTO_INCREMENT, `emp_ssn` INT UNSIGNED NOT NULL, `emp_fname` VARCHAR(15) NOT NULL, `emp_lname` VARCHAR(20) NOT NULL, `emp_street` VARCHAR(45) NOT NULL, `emp_city` VARCHAR(45) NOT NULL, `emp_state` CHAR(2) NOT NULL, `emp_zip` CHAR(9) NOT NULL, `emp_phone` CHAR(15) NOT NULL, `emp_email` VARCHAR(100) NOT NULL, `emp_doh` DATE NOT NULL, `emp_is_inspect` ENUM('y', 'n') NOT NULL, `emp_notes` VARCHAR(250) NULL, PRIMARY KEY (`emp_id`)) ENGINE = InnoDB; SHOW WARNINGS; -- ----------------------------------------------------- -- Table `sls11n`.`dependent` -- ----------------------------------------------------- DROP TABLE IF EXISTS `sls11n`.`dependent` ; SHOW WARNINGS; CREATE TABLE IF NOT EXISTS `sls11n`.`dependent` ( `dep_id` TINYINT UNSIGNED NOT NULL AUTO_INCREMENT, `emp_id` TINYINT UNSIGNED NOT NULL, `dep_ssn` INT UNSIGNED NOT NULL, `dep_fname` VARCHAR(45) NOT NULL, `dep_lname` VARCHAR(45) NOT NULL, `dep_street` VARCHAR(45) NOT NULL, `dep_city` VARCHAR(45) NOT NULL, `dep_state` CHAR(2) NOT NULL, `dep_zip` CHAR(9) NOT NULL, `dep_phone` CHAR(10) NOT NULL, `dep_email` VARCHAR(100) NOT NULL, `dep_notes` VARCHAR(250) NULL, PRIMARY KEY (`dep_id`), INDEX `fk_dependent_employee1_idx` (`emp_id` ASC), CONSTRAINT `fk_dependent_employee1` FOREIGN KEY (`emp_id`) REFERENCES `sls11n`.`employee` (`emp_id`) ON DELETE NO ACTION ON UPDATE NO ACTION) ENGINE = InnoDB; </code></pre> <p>Any one have any ideas?

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.

If you are curious you may find further information in the browser console, which is accessible through the devtools (F12).
