MySQL - Copy row to another table with foreign key - mysql

i want to copy 1 row from this table:
tableold
-----------
oid (primary key, auto_incremment)
name
age
detail
to this table:
tablenew
------------
nid (primary key, auto_incremment)
fid (foreign key to another table)
name
age
detail
With this SQL-Command:
INSERT INTO tablenew (tablenew.name, tablenew.age, tablenew.detail)
SELECT tableold.name, tableold.age, tableold.detail
FROM tableold
WHERE tableold.oid = 123;
But i get the error:
ERROR 1364 (HY000): Field 'fid' doesn't have a default value
Is there any possibility to manually add the foreign key 'fid' to the SQL-Command?
*Edit, i have added the CREATE table statements:
CREATE TABLE `othertable` (
`fid` int NOT NULL AUTO_INCREMENT,
`value1` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`value2` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`value3` longtext CHARACTER SET utf8 COLLATE utf8_general_ci,
`value4` longtext CHARACTER SET utf8 COLLATE utf8_general_ci,
PRIMARY KEY (`fid`),
) ENGINE=InnoDB AUTO_INCREMENT=66 DEFAULT CHARSET=utf8;
CREATE TABLE `tablenew` (
`nid` int NOT NULL AUTO_INCREMENT,
`fid` int NOT NULL,
`name` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`age` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`detail` varchar(255) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
PRIMARY KEY (`sid`),
KEY `fid_fkey` (`fid`),
CONSTRAINT `fid_fkey` FOREIGN KEY (`fid`) REFERENCES `othertable` (`fid`) ON DELETE RESTRICT ON UPDATE RESTRICT
) ENGINE=InnoDB AUTO_INCREMENT=6 DEFAULT CHARSET=utf8;
CREATE TABLE `tableold` (
`oid` int NOT NULL AUTO_INCREMENT,
`name` varchar(60) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`age` varchar(60) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
`detail` varchar(60) CHARACTER SET utf8 COLLATE utf8_general_ci DEFAULT NULL,
PRIMARY KEY (`oid`)
) ENGINE=InnoDB AUTO_INCREMENT=157 DEFAULT CHARSET=utf8;


I have solved it:
INSERT INTO tablenew (tablenew.fid, tablenew.name, tablenew.age, tablenew.detail)
SELECT 'value', tableold.name, tableold.age, tableold.detail
FROM tableold
WHERE tableold.oid = value;

I get the error: incorrect table definition [duplicate]

This question already has answers here:
There can be only one auto column
(6 answers)
Closed 2 years ago.
Im using phpmyadmin for the first time and I get this error: incorrect table definition. there can be only one auto column and it must be defined as key. What am I doing wrong?
This is my code:
CREATE TABLE `database_reservering`.`formData` (
`nameTeacher` VARCHAR(50) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL ,
`nameChild` VARCHAR(50) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL , `email` VARCHAR(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL ,
`age` INT(11) NOT NULL ,
`date` DATE NOT NULL ,
`comment` VARCHAR(300) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL ,
`id` INT(30) UNSIGNED NOT NULL AUTO_INCREMENT ,
PRIMARY KEY (`nameTeacher`)
) ENGINE = InnoDB;

The actual error message is:
Incorrect table definition; there can be only one auto column and it must be defined as a key
The problem is that you have id as auto-increment, but the primary key is on nameTeacher. This is not allowed. You can change the statement to make id the primary key, and put a unique constraint on nameTeacher. This implements the same logic, but is valid MySQL syntax:
CREATE TABLE `formData` (
...
PRIMARY KEY (`id`),
UNIQUE (`nameTeacher`)
) ENGINE = InnoDB;
Demo on DB Fiddle

Change
PRIMARY KEY (nameTeacher)
to
PRIMARY KEY (id)
Full statement:
CREATE TABLE formData (
nameTeacher VARCHAR(50) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
nameChild VARCHAR(50) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL,
email VARCHAR(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL ,
age INT(11) NOT NULL ,
`date` DATE NOT NULL ,
`comment` VARCHAR(300) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL ,
id INT UNSIGNED NOT NULL AUTO_INCREMENT ,
PRIMARY KEY (id)) ENGINE = InnoDB;

What do you want to achieve when PK is set to the column other than AUTO_INCREMENT?
If you want to have separate independent autoincremented sequence for each nameTeacher value then alter the engine to MyISAM and define PK like (nameTeacher, id):
CREATE TABLE `formData` (
`nameTeacher` VARCHAR(50) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL ,
`nameChild` VARCHAR(50) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL ,
`email` VARCHAR(255) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL ,
`age` INT(11) NOT NULL , `date` DATE NOT NULL ,
`comment` VARCHAR(300) CHARACTER SET utf8 COLLATE utf8_general_ci NOT NULL ,
`id` INT(30) UNSIGNED NOT NULL AUTO_INCREMENT ,
PRIMARY KEY (`nameTeacher`, `id`)
) ENGINE = MyISAM;

I want to add some foreign key.
But it always that: #1215 - Cannot add foreign key constraint
ALTER TABLE `tb_product` ADD CONSTRAINT `manufacturer` FOREIGN KEY (`manufacturer`) REFERENCES `tb_manufacturer` (`manufacturer`);

The following runs thru fine now. The tables with a drop above them needed tweaked with primary keys added (or at least a non-unique key). Otherwise child table depending on it can't look it up for the FK. I tested it.

ALTER TABLE `tb_item` ADD CONSTRAINT `status` FOREIGN KEY (`status`) REFERENCES `tb_status` (`status`);

At the time of foreign key constraint, below points keep in mind-
both (master/child) columns should have same data type/length.
column in master table should be indexed.
In your case problem seems that related column in master table is not indexed.

Error 1005: Can't create table can't find where the issue is

I have created a EER model using MySQL Workbench (latest release). Apparently all is fine but when I try to do a FORWARD ENGINEER I get the common Error 1005: Can't create table. As suggested in this post I check every step on the first answer but without success, can any give some extra eyes to my query and try to find where my error is? I can't see it.
This is the error generated by the tool:

The issue is that tb_order doesn't specify a charset or collation like the other tables so will use the database default.
If the default is different from utf8 and utf8_unicode_ci then the foreign key on a text field wont work.

Can I download the Phpmyadmin Database?

I accidentally deleted the phpmyadmin database that came with it. Now I'm getting errors like:
SQL query: DocumentationEdit Edit
SELECT `db_name` , `comment`
FROM `phpmyadmin`.`pma_column_info`
WHERE `column_name` = '(db_comment)'
MySQL said: Documentation
#1146 - Table 'phpmyadmin.pma_column_info' doesn't exist
So can I download the database again somewhere? Thanks!

I downloaded the package from their website and extracted the table setup script, you can run the following queries which will re-create the required tables:

By default, the sql to create the phpmyadmin database is in /PhpMyAdminFolder/examples/create_tables.sql, as stated on the documentation (section "phpMyAdmin configuration storage").
There is no need to reinstall it all just for that.

I have filled the contacts with 111 contacts, the states are simply all of the states, and cities have corresponding id keys that relate to the state id, zip codes have a key to match to a city.
The query is to generate a list of people to match up to the proper fields. Here is the query.
SELECT concat(contacts.last,' ', contacts.first) as name
, cities.city
, zips.zip
FROM contacts
JOIN cities
ON cities.id = contacts.city_id
JOIN states ON states.id = contacts.state_id
JOIN zips ON zips.cityid = cities.id
This query, return 338 rows, of a possible 11 contacts. There obvious duplicates. This happens when I join zip codes, which because they belong to more than 1 city, it gets matched for each city (I think thats what is happening). Anyone have an answer on how to properly join these tables?
Thank you.

I believe that you should re-think the surrogate key usage on a lot of these tables and use natural keys where possible. Taking the state table for an example, in most cases it will be acceptable to simply use the state short (ie. TX vs. Texas) for data and display purposes. This means that if you removed the incrementing ID on the states table and used a natural key for each state, you would reduce the necessecity of a join in 90% of cases.
Then use state.abbriviation as the FK in tables that need to store state values. Extending this to zipcodes and cities, you can FK the state abbr to the city table, and make a compound FK form the cities table to the contacts table giving you a key for both the city and the state at the same time.
Example schema (excluded zipcodes table and shortened contacts table):
CREATE TABLE IF NOT EXISTS `states` (
`state_id` CHAR(2) NOT NULL ,
`name` VARCHAR(45) NULL ,
PRIMARY KEY (`state_id`) ,
UNIQUE INDEX `state_name` (`name` ASC)
)
ENGINE = InnoDB;
CREATE TABLE IF NOT EXISTS `cities` (
`state_id` CHAR(2) NOT NULL ,
`city_name` VARCHAR(255) NOT NULL ,
PRIMARY KEY (`state_id`, `city_name`) ,
INDEX `fk_city_state_id` (`state_id` ASC) ,
CONSTRAINT `fk_city_state_id`
FOREIGN KEY (`state_id` )
REFERENCES `states` (`state_id` )
ON DELETE NO ACTION
ON UPDATE NO ACTION
)
ENGINE = InnoDB;
CREATE TABLE IF NOT EXISTS `contacts` (
`contacts_id` INT NOT NULL AUTO_INCREMENT ,
`state` CHAR(2) NULL ,
`city` VARCHAR(255) NULL ,
PRIMARY KEY (`contacts_id`) ,
INDEX `fk_contact_city` (`state` ASC, `city` ASC) ,
INDEX `fk_contact_state` (`state` ASC) ,
CONSTRAINT `fk_contact_city`
FOREIGN KEY (`state` , `city` )
REFERENCES `cities` (`state_id` , `city_name` )
ON DELETE NO ACTION
ON UPDATE NO ACTION,
CONSTRAINT `fk_contact_state`
FOREIGN KEY (`state` )
REFERENCES `states` (`state_id` )
ON DELETE NO ACTION
ON UPDATE NO ACTION
)
ENGINE = InnoDB;
-- -----------------------------------------------------
-- Data for table `states`
-- -----------------------------------------------------
SET AUTOCOMMIT=0;
INSERT INTO `states` (`state_id`, `name`) VALUES ('TX', 'Texas');
INSERT INTO `states` (`state_id`, `name`) VALUES ('CA', 'California');
INSERT INTO `states` (`state_id`, `name`) VALUES ('OR', 'Oregon');
COMMIT;
-- -----------------------------------------------------
-- Data for table `cities`
-- -----------------------------------------------------
SET AUTOCOMMIT=0;
INSERT INTO `cities` (`state_id`, `city_name`) VALUES ('CA', 'modesto');
INSERT INTO `cities` (`state_id`, `city_name`) VALUES ('OR', 'protland');
INSERT INTO `cities` (`state_id`, `city_name`) VALUES ('TX', 'Dallas');
COMMIT;
Now your query is simplified except in the extreme case where you'd need a full state nomenclature:
SELECT
concat(contacts.last,' ', contacts.first) as name,
city,
state,
zip
FROM contacts
WHERE {INSERTWHERE}

your tables a properly joined. i think the problem you have here is that you have normalized your data improperly and gone too far. just store the address as provided. don't try and split it in to table with numeric ID's.
for example, what possible benefit do you get by storing the state as a number in the contact table instead of just the state code? and the same question applies to city.
