Question

How do I import this database correctly?

https://github.com/samanz/cakecart

Every time I import then I get this error:

Error

SQL query:

CREATE TABLE `categories` (
`id` INT( 11 ) NOT NULL AUTO_INCREMENT ,
`name` VARCHAR( 50 ) NULL default NULL ,
`parent_id` INT( 11 ) UNSIGNED default '0',
`order` INT( 3 ) default '0',
`image` VARCHAR( 50 ) NULL default NULL ,
`ids` VARCHAR( 225 ) NULL default NULL ,
`url` VARCHAR( 255 ) NULL default NULL ,
PRIMARY KEY ( `id` ) ,
FOREIGN KEY ( `parent_id` ) REFERENCES categories( `id` ) ,
UNIQUE KEY `url` ( `url` )
);

MySQL said: Documentation
#1005 - Can't create table 'db.categories' (errno: 150) 

Foreign key is error 150, but there’s much more tables than this error.

Please try import first then answer.

THis one works:

CREATE TABLE `categories` (
`id` INT( 11 ) NOT NULL AUTO_INCREMENT ,
`name` VARCHAR( 50 ) NULL default NULL ,
`parent_id` INT( 11 ),
`order` INT( 3 ) default '0',
`image` VARCHAR( 50 ) NULL default NULL ,
`ids` VARCHAR( 225 ) NULL default NULL ,
`url` VARCHAR( 255 ) NULL default NULL ,
PRIMARY KEY ( `id` ) ,
FOREIGN KEY ( `parent_id` ) REFERENCES categories( `id` ) ,
UNIQUE KEY `url` ( `url` )
);

Edit: Actually you only need to remove unsigned to make it work. But I don’t really know why you want it to be default 0. It should be default NULL which is the default default.. 🙂

I believe the type of parent_id must be the same as id.
