Here is my users.sql file :
CREATE TABLE users (
'id' bigint(20) NOT NULL auto_increment,
'md5_id' varchar(200) collate latin1_general_ci NOT NULL default '',
'user_name' varchar(200) collate latin1_general_ci NOT NULL default '',
'user_email' varchar(220) collate latin1_general_ci NOT NULL default '',
) ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci
AUTO_INCREMENT=55 ;
Here id is the primary key.
Now this is the second table notifications.sql:
CREATE TABLE 'notifications' (
'notificationid' int(11) NOT NULL,
'creation_date_time' varchar(30) NOT NULL,
'view_date_time' varchar(30) NOT NULL,
'user_id bigint(big) NOT NULL,
'notification_text' varchar(255) NOT NULL,
'is_viewed' varchar(3) NOT NULL
)
Now when i try to add id in notifications table as foreign key it gives 1215 error. I don't know where i am going wrong.
This is my alter table code:
ALTER TABLE 'notifications'
ADD FOREIGN KEY (id) REFERENCES users(id)
ON DELETE CASCADE ON UPDATE CASCADE
You have to add the engine,charste and collate information to the second table too:
CREATE TABLE 'notifications' (
'notificationid' int(11) NOT NULL,
'creation_date_time' varchar(30) NOT NULL,
'view_date_time' varchar(30) NOT NULL,
'user_id bigint(big) NOT NULL,
'notification_text' varchar(255) NOT NULL,
'is_viewed' varchar(3) NOT NULL
)
ENGINE=MyISAM DEFAULT CHARSET=latin1 COLLATE=latin1_general_ci
Also your table notifications ha no column id. You have to add this first and Name it user_id:
ALTER TABLE 'notifications'
ADD Column user_id int(11);
ALTER TABLE 'notifications'
ADD FOREIGN KEY (user_id) REFERENCES users(id)
ON DELETE CASCADE ON UPDATE CASCADE

So i'm trying to make a old project work again but when i put back my tables to the new database i'm having this issue

So the problem/reason is There is no index in the referenced table where the referenced columns appear as the first columns
You need to create indexes on the referencing column:
CREATE INDEX `ix_install__agents_name` ON `install__agents` (`name`);
CREATE INDEX `ix_install__ports_protocol` ON `install__ports` (`protocol`);
CREATE INDEX `ix_install__zone_slug` ON `install__zone` (`slug`);

On the last part here, it is not working. It gives error code 1005
The alter table at the bottom is the probably the issue. I am just not sure how to fix it. Any help is appreciated. Thanks.
The foreign key is incorrectly formed.
You connect customer.c_ID should be equal to relationaltable.c_order
customer.c_ID is varchar(15) NOT NULL
relationaltable.c_order is int(100) NOT NULL
The data type and also the length has to be matching
I'm trying to add a foreign key constraint on my schema devair from field user_id of table bluePrints to the PK id of table users but I get an error:
ERROR 1215: Cannot add foreign key constraint
Here are my table definitions:
users:
CREATE TABLE `users` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`email` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`password` varchar(60) COLLATE utf8_unicode_ci NOT NULL,
`remember_token` varchar(100) COLLATE utf8_unicode_ci DEFAULT NULL,
`created_at` timestamp NULL DEFAULT NULL,
`updated_at` timestamp NULL DEFAULT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `users_email_unique` (`email`)
) ENGINE=InnoDB AUTO_INCREMENT=19 DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
bluePrints:
CREATE TABLE `bluePrints` (
`id` int(10) unsigned NOT NULL AUTO_INCREMENT,
`bluePrintName` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`description` varchar(255) COLLATE utf8_unicode_ci NOT NULL,
`user_id` int(10) NOT NULL,
`created_at` timestamp NULL DEFAULT NULL,
`updated_at` timestamp NULL DEFAULT NULL,
PRIMARY KEY (`id`),
KEY `uid` (`user_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
And the offending alter table statement:
ALTER TABLE `devair`.`bluePrints`
ADD CONSTRAINT `bp_u`
FOREIGN KEY (user_id)
REFERENCES `devair`.`users` (id)
ON DELETE CASCADE
ON UPDATE CASCADE;
The simple answer would be that you need to do this:
ALTER TABLE table1 ADD CONSTRAINT fk_bp_id FOREIGN KEY (columnFromTable1) REFERENCES table2(columnReferencedFromTable2);
The problem is the 'unsigned' in the bluePrints table. Once it's unsigned, then it works.
Now i have to figure out how to get laravel to use unsigned.
I can't figure out how to use on delete cascade in my example.
CREATE TABLE `users` (
`login` varchar(16) NOT NULL,
`password` varchar(16) NOT NULL,

One table stores informations about employee and if he has account(login) there is another table with logins and passwords.
My goals:
Not every employee needs to have user account(that means - unique record in Users table) so Employees.Login shouldn't be restricted with NOT NULL.
I want possiblity to add new user in Users and then assign it to some employee.
When I delete employee, related unique user is also deleted(if he had one).
First two are already done. I don't know how to make 3 happen now.
You've put the CONSTRAINT in the wrong CREATE TABLE statement. It goes on the referencing table, which is "users", because that's the table you want to automatically delete from when a row in the other table is deleted.
You want to put a nullable "ID" in the "users" table, which is unique and a foreign key to "employees".
Use this query :
CREATE TABLE `users` (
`login` varchar(16) NOT NULL,
`password` varchar(16) NOT NULL,
PRIMARY KEY (`login`),
UNIQUE KEY `login` (`login`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
CREATE TABLE `employees` (
`ID` int(11) NOT NULL AUTO_INCREMENT,
`Name` varchar(20) NOT NULL,
`Surname` varchar(25) NOT NULL,
`Birthday` date NOT NULL,
`Adres` varchar(50) NOT NULL,
`Telephone` varchar(25) NOT NULL,
`login` varchar(16) DEFAULT NULL,
PRIMARY KEY (`ID`),
UNIQUE KEY `login` (`login`),
CONSTRAINT `employees_ibfk_1` FOREIGN KEY (`login`) REFERENCES `users` (`login`) ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Based on suggestion from Hammerite now my tables definion looks like this:
CREATE TABLE `employees` (
`ID` int(11) NOT NULL AUTO_INCREMENT,
`Name` varchar(20) NOT NULL,
`Surname` varchar(25) NOT NULL,
`Birthday` date NOT NULL,
`Adres` varchar(50) NOT NULL,
`Telephone` varchar(25) NOT NULL,
PRIMARY KEY (`ID`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
CREATE TABLE `users` (
`login` varchar(16) NOT NULL,
`password` varchar(16) NOT NULL,
`employee_id` int(11) NOT NULL,
PRIMARY KEY (`login`),
UNIQUE KEY `login` (`login`),
UNIQUE KEY `employee_id` (`employee_id`),
CONSTRAINT `users_ibfk_1` FOREIGN KEY (`employee_id`) REFERENCES `employees` (`ID`) ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8
I have deleted login column from employees table
I have created another column employee_id in User table. It's unique foreign key and cannot be null since I dont want user accounts that are not used by anybody.
Now If I do this:
INSERT INTO users VALUES('login123','password',2);
then this row will be deleted after I do this:
DELETE FROM employees WHERE id=2;
I was sure that I need to make some reference in employees table to users table, thats why I didn't think about solution like this.
THANKS!

I tried the suggestion in this relevant post, but there were no results. This is a new database that hasn't actually been used yet; I've just filled it with fake data. Any ideas would be greatly appreciated.
There is a foreign key constraint on tblOrderItems that its ItemID needs to reference an ItemID that already exists in tblCatalogItems.
CONSTRAINT `ItemID` FOREIGN KEY (`ItemID`) REFERENCES `tblCatalogItems` (`ItemID`),
The message only means that you're trying to update tblOrderItems to reference the item in tblCatalogItems with ItemID= 0004, but that item does not exist.
Since ItemID is a varchar, you probably want to quote the 0004 or it may be converted to an int 4 before conversion to varchar. That may be your problem if the row with ItemID = 0004 actually exists.
UPDATE tblOrderItems SET `ItemID` = '0004' WHERE `OrderNum`= 203 AND `OrderItemID` = 26
Without seeing the table data I can't be sure, but I'm guessing it's because there is no record in tblCatalogItems with an ItemID of '0004'.
Also, you probably need to quote the 0004 in your update statement since the column is defined as character (varchar(10)) not number (int).
There is a foreign key relationship defined between tblCatalogItems.ItemId and tblOrderItems.ItemId which means that any row in tblOrderItems can only have a value for ItemId that matches an ItemId found in tblCatalogItems.
You would therefore need to insert a record into 'tblCatalogItems' with an ItemId of '0004' first, before running your update on tblOrderItems
Alternatively you need to change the SET ItemID = clause in your update to set a value that matches to an ItemId value that actually exists in the tblCatalogItems table
The data type needs to match on both sides of your foreign key constraint. Here you have a varchar(50) referring a varchar(10), which isn't allowed.
