i made 2 tables like this,
CREATE TABLE personal (
id INT(255) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
name VARCHAR(30) NOT NULL,
email VARCHAR(50),
created_at DATETIME);
CREATE TABLE personal_details (
id INT(255) UNSIGNED AUTO_INCREMENT PRIMARY KEY NOT NULL,
personal_id INT(255),
tittle VARCHAR(10) NOT NULL,
family_name VARCHAR(50) NOT NULL,
given_name VARCHAR(50) NOT NULL,
place_of_birth VARCHAR(50) NOT NULL,
date_of_birth DATE NOT NULL,
gender VARCHAR(25) NOT NULL,
country_citizen VARCHAR(50) NOT NULL,
national_identity_number INT(50) NOT NULL,
passport_no INT(50) NOT NULL,
issue_date DATE NOT NULL,
expiry_date DATE NOT NULL,
FOREIGN KEY (personal_id) REFERENCES personal(id)
);
but it returns an error like this Error Code: 1215. Cannot add foreign key constraint
even tough i already follow this solution from another question
https://stackoverflow.com/a/16969116/17067132
I am a bit confused aboud the use scholarship_uiii in between the two CREATE-statements.
But the reason for the error is that you are missing the UNSIGNED for your personal_id field.
So your second CREATE-statement should read:
CREATE TABLE personal_details (
id INT(255) UNSIGNED AUTO_INCREMENT PRIMARY KEY NOT NULL,
personal_id INT(255) UNSIGNED,
tittle VARCHAR(10) NOT NULL,
family_name VARCHAR(50) NOT NULL,
given_name VARCHAR(50) NOT NULL,
place_of_birth VARCHAR(50) NOT NULL,
date_of_birth DATE NOT NULL,
gender VARCHAR(25) NOT NULL,
country_citizen VARCHAR(50) NOT NULL,
national_identity_number INT(50) NOT NULL,
passport_no INT(50) NOT NULL,
issue_date DATE NOT NULL,
expiry_date DATE NOT NULL,
FOREIGN KEY (personal_id) REFERENCES personal(id)
);
I've been trying to fix the error mentioned in the title with no luck. My data types and lengths are the same and I've also set the ENGINE and CHARSET.
Please take a look at my code. Users table:
CREATE TABLE users (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
sa_id VARCHAR(30) NOT NULL,
name VARCHAR(30) NOT NULL,
surname VARCHAR(30) NOT NULL,
address1 VARCHAR(70),
address2 VARCHAR(70) NOT NULL,
suburb VARCHAR(50) NOT NULL,
city VARCHAR(30) NOT NULL,
province VARCHAR(30) NOT NULL,
zip INT(6) NOT NULL,
email VARCHAR(70) NOT NULL,
password CHAR(32) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Votes table:
CREATE TABLE votes (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
sa_id VARCHAR(30) NOT NULL,
party VARCHAR(30) NOT NULL,
province VARCHAR(50) NOT NULL,
FOREIGN KEY (sa_id) REFERENCES users(sa_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Error: Can't create table 'savs_db'.'votes' (errno: 150 "Foreign key constraint is incorrectly formed")
Took #Michal Hynčica's advice and found the solution. I failed to index the non-key column I was referencing. I added INDEX (sa_id) to line 14.
Solution:
CREATE TABLE IF NOT EXISTS users (
id INT(6) UNSIGNED AUTO_INCREMENT PRIMARY KEY,
sa_id VARCHAR(30) NOT NULL,
name VARCHAR(30) NOT NULL,
surname VARCHAR(30) NOT NULL,
address1 VARCHAR(70),
address2 VARCHAR(70) NOT NULL,
suburb VARCHAR(50) NOT NULL,
city VARCHAR(30) NOT NULL,
province VARCHAR(30) NOT NULL,
zip INT(6) NOT NULL,
email VARCHAR(70) NOT NULL,
password CHAR(32) NOT NULL,
INDEX (sa_id)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
I am reverse engineering a database in MySQL Workbench but it doesn't seem to be importing or recognising the foreign keys. Which means I cant get it to draw the relationships.
While I am trying to get this to work I am using a snippet of a couple of tables, so its nothing complex.
Here are the 2 demo tables that I am trying to get to work:
CREATE TABLE users (
UserID varchar(32) NOT NULL,
OrgID varchar(6) NOT NULL,
RegionID int NULL,
LocationID int NULL,
Name nvarchar(60) NULL,
Crypt varchar(32) NULL,
Security int NULL,
Status int NULL,
PRIMARY KEY ( UserID ),
CONSTRAINT fk_OrgID_Users FOREIGN KEY (OrgID) REFERENCES Organisations(OrgID)
);
CREATE TABLE Organisations(
OrgID varchar(6) NOT NULL,
Name nvarchar(70) NOT NULL,
Address1 varchar(50) NULL,
Address2 varchar(50) NULL,
Address3 varchar(50) NULL,
Town varchar(20) NULL,
County varchar(20) NULL,
PostCode varchar(10) NULL,
NotificationEmail varchar(500) NOT NULL,
PRIMARY KEY ( OrgID )
)
But in MySQL Workbench, there are no relationships or foreign keys being created. If I look at the table data, and the foreign keys tab, theres nothing there?
I think I'm creating the foreign keys correctly, so is there a reason its not importing them?
On further research there were several things that I needed to do for this to work.
I had to make sure that the tables reverse engineered from MySQL were defined as InnoDB.
And I also had to remove the foreign key constraint from the create table command and create the foreign keys after the tables were created, like so:
CREATE TABLE Users (
UserID varchar(32) NOT NULL,
OrgID varchar(6) NOT NULL,
RegionID int NULL,
LocationID int NULL,
Name nvarchar(60) NULL,
Crypt varchar(32) NULL,
Security int NULL,
Status int NULL,
PRIMARY KEY ( UserID )
) ENGINE=InnoDB;
CREATE TABLE Organisations(
OrgID varchar(6) NOT NULL,
Name nvarchar(70) NOT NULL,
Address1 varchar(50) NULL,
Address2 varchar(50) NULL,
Address3 varchar(50) NULL,
Town varchar(20) NULL,
County varchar(20) NULL,
PostCode varchar(10) NULL,
NotificationEmail varchar(500) NOT NULL,
PRIMARY KEY ( OrgID )
) ENGINE=InnoDB;
ALTER TABLE Users ADD CONSTRAINT fk_OrgID_Users FOREIGN KEY (OrgID) REFERENCES Organisations(OrgID);
This then worked fine and the relationships were visible and connected in MySQL Workbench

Database Layout
I'm a novice trying my hand at creating a database for a friend's startup.
I created a database layout dbdesigner.net (diagram attached). I exported the SQL and have been trying repeatedly to import it into my phpmyadmin database using the sql tab.
Unfortunatley it keeps throwing up error after error the latest of which really has me stuck.
All help solving the issue and constructive feedback is greatly appreciated. Thanks in advance :)

That's cause you haven't specified data type for that column for table mtn_readings.
You have
`mtn_readings_id` AUTO_INCREMENT,
Should be
`mtn_readings_id` INT NOT NULL AUTO_INCREMENT,
So exactly where is the field type here?
CREATE TABLE `mtn_readings`(
`mtn_readings_id` AUTO_INCREMENT,
You didn't specify int/varchar/text/etc..., so auto_increment is unexpected/invalid.

Try creating all the Primary keys first, then add the FK constraint. Odds are the FK constraint won't add because it's being linked to a PK that hasn't been made yet.
