I suggest something is wrong with the foreign keys, but i can't find a hint.
error while importing the sql:
ALTER TABLE `claim`
ADD CONSTRAINT `FK_66A8F1231B7B246A` FOREIGN KEY (`purchaseOrder_id`) REFERENCES `PurchaseOrder` (`id`) ON DELETE CASCADE,
ADD CONSTRAINT `FK_66A8F1237294869C` FOREIGN KEY (`article_id`) REFERENCES `Article` (`id`);
#1005 - Can't create table 'databasename.#sql-5c7_568c0' (errno: 150)
I also checked the conditions of this answer MySQL Creating tables with Foreign Keys giving errno: 150
But i couldn't find the mistake.
Any guesses?

I was helping a friend migrate his WordPress to AWS. The whole WordPress was exported by him using WPClone and I'm going to import it to RDS (Aurora). I'm not a pro DB guy and I only knew basic MySQL commands. I was trying to restore a database but during the restoration I encountered ERROR: ERROR 1215 (HY000): Cannot add foreign key constraint.
I executed show engine innodb status and checked the LATEST FOREIGN KEY ERROR and this is what I got but I have no idea how to resolve this.

Two problems:
Create tables in this order: child tables, parent table (with foreign keys). Replace CREATE TABLE statements:
wp_supsystic_ss_projects
wp_supsystic_ss_networks
wp_supsystic_ss_project_networks.
Child table wp_supsystic_ss_networks does not exist in the script.
I have created a database "webportal". and this is my "user" table script
DROP TABLE IF EXISTS `user`;
CREATE TABLE `user` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`username` varchar(255) DEFAULT NULL,
`password` varchar(255) DEFAULT NULL,
`firstName` varchar(255) DEFAULT NULL,
`lastName` varchar(255) DEFAULT NULL,
`dateRegistered` DATE DEFAULT NULL,
`skypeID` int(11) DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB AUTO_INCREMENT=4 DEFAULT CHARSET=utf8;
and this one is "catalog" table script.
DROP TABLE IF EXISTS `catalog`;
create table catalog(
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_id` int(11) NOT NULL,
`link` VARCHAR(100) NOT NULL,
`comment` VARCHAR(100) NOT NULL,
`inserDate` DATE DEFAULT NULL,
`content` longblob NOT NULL,
PRIMARY KEY (`id`),
CONSTRAINT `fk_catalog` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
and when I try to execute the second script in the command line, I get this error...
ERROR 1215 (HY000): Cannot add foreign key constraint.
What is wrong with this code?
It seems you are using a old version of MySQL, you can add a INDEX clause to foreign key field to fix the problem:
DROP TABLE IF EXISTS `catalog`;
create table `catalog`(
`id` int(11) NOT NULL AUTO_INCREMENT,
`user_id` int(11) NOT NULL,
`link` VARCHAR(100) NOT NULL,
`comment` VARCHAR(100) NOT NULL,
`inserDate` DATE DEFAULT NULL,
`content` longblob NOT NULL,
PRIMARY KEY (`id`),
INDEX (`user_id`),
CONSTRAINT `fk_catalog` FOREIGN KEY (`user_id`) REFERENCES `user` (`id`) ON DELETE CASCADE ON UPDATE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
I have created the following tables and have no idea why my foreign key constraint script is not working.
CREATE TABLE IF NOT EXISTS `project` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`project_id` varchar(60) NOT NULL,
`project_name` varchar(500) NOT NULL,
`cons_bal` int(11) NOT NULL,
`non_cons_bal` int(11) NOT NULL,
`budget_head` varchar(100) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 AUTO_INCREMENT=1 ;
And here is my another table:
CREATE TABLE IF NOT EXISTS `project_map` (
`id` int(11) NOT NULL,
`project_id` varchar(60) NOT NULL,
`head` int(11) NOT NULL,
PRIMARY KEY (`id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
And here is my add constraint line:
alter table project_map add constraint p_map_fk001 foreign key (`project_id`) references project(`project_id`)
Any help would be nice. Thank you.
In the referenced table, there must be an index where the referenced columns are listed as the first columns in the same order.
Refer: http://dev.mysql.com/doc/refman/5.6/en/innodb-foreign-key-constraints.html
So try:
CREATE TABLE `project` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`project_id` varchar(60) NOT NULL,
`project_name` varchar(500) NOT NULL,
`cons_bal` int(11) NOT NULL,
`non_cons_bal` int(11) NOT NULL,
`budget_head` varchar(100) NOT NULL,
PRIMARY KEY (`id`),
KEY `project_id` (`project_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
CREATE TABLE `project_map` (
`id` int(11) NOT NULL,
`project_id` varchar(60) NOT NULL,
`head` int(11) NOT NULL,
PRIMARY KEY (`id`),
KEY `project_id` (`project_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8
ALTER TABLE `project_map` ADD CONSTRAINT
`p_map_fk001` FOREIGN KEY (`project_id`)
REFERENCES project(`project_id`);
I am trying to create a cross database foreign key. When I run the following code on the same database
CREATE TABLE `t1` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`int_id` varchar(128) COLLATE utf8_unicode_ci NOT NULL,
PRIMARY KEY (`id`),
UNIQUE KEY `int_id` (`int_id`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
CREATE TABLE `t2` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`ext_id` varchar(128) COLLATE utf8_unicode_ci NOT NULL,
PRIMARY KEY (`id`),
KEY `ext_id` (`ext_id`),
CONSTRAINT `t2_ibfk_1` FOREIGN KEY (`ext_id`) REFERENCES `t1` (`int_id`) ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
However, when create t1 on one databse (d1) and then run the following code on a second databse (d2), I receive the generic error: #1005 - Can't create table 'userdata.t2' (errno: 150)
CREATE TABLE `t2` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`ext_id` varchar(128) COLLATE utf8_unicode_ci NOT NULL,
PRIMARY KEY (`id`),
KEY `ext_id` (`ext_id`),
CONSTRAINT `t2_ibfk_1` FOREIGN KEY (`ext_id`) REFERENCES `d1.t1` (`int_id`) ON DELETE CASCADE
) ENGINE=InnoDB DEFAULT CHARSET=utf8 COLLATE=utf8_unicode_ci;
Any help will be appreciated. Thanks!
Your syntax is not correct, try this
CREATE TABLE `t2` (

now i have the error when i try to import:
#1005 - Can't create table 'kobeco_yii.tbl_comments' (errno: 150) (Details: Percona-XtraDB, Supports transactions, row-level locking, and foreign keys )
You're trying to create tbl_comments before your other tables. tbl_comments requires tables tbl_users and tbl_topics for foreign key constraints.
Try moving the CREATE TABLE for tbl_comments to below the others.
Your first table (table_commets) has constraints to tables that doesn't exist yet. This may be an issue of you are creating them in that order.
Create table_usr and table_topics first.
