What is my syntax error in this mySQL create table statement? - mysql

I am typing the following:
CREATE TABLE events (
`id` mediumint unsigned not null auto_increment,
`user` varchar(30) not null,
`time` datetime not null,
`duration` decimal(5,2) default 1.0,
`title` tinytext not null,
`location` text default null,
`tag` ENUM(‘red’,’orange’,’yellow’,’green’,’blue’,’violet’,’brown’,’black’) default null,
PRIMARY KEY (`id`),
FOREIGN KEY (`user`) references users (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
and I am getting the following response:
ERROR 1064 (42000): You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near '‘red’,’orange’,’yellow’,’green’,’blue’,’violet’,’brown' at line 8
This may be a case of tired eyes, but I am stumped. What is wrong with my enum statement?

Change:
`tag` ENUM(‘red’,’orange’,’yellow’,’green’,’blue’,’violet’,’brown’,’black’)
To:
`tag` ENUM('red', 'orange','yellow','green','blue','violet','brown','black')

Enclose data inside ENUM by Single Quote
CREATE TABLE `events` (
`id` mediumint unsigned not null auto_increment,
`user` varchar(30) not null,
`time` datetime not null,
`duration` decimal(5,2) default 1.0,
`title` tinytext not null,
`location` text default null,
`tag` ENUM('red','orange','yellow','green','blue','violet','brown','black') default null,
PRIMARY KEY (`id`),
FOREIGN KEY (`user`) references users (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
Note: event is a MySQL RESERVED KEYWORD. When you use MySQL RESERVED KEYWORDS as identifier enclosing by backtick is recommended.

Problem is with the quotes(‘red’) you used for ENUM values try this ;)
CREATE TABLE events (
`id` mediumint unsigned not null auto_increment,
`user` varchar(30) not null,
`time` datetime not null,
`duration` decimal(5,2) default 1.0,
`title` tinytext not null,
`location` text default null,
`tag` ENUM('red','orange','yellow','green','blue','violet','brown','black') default null,
PRIMARY KEY (`id`),
FOREIGN KEY (`user`) references users (`username`)
) ENGINE=InnoDB DEFAULT CHARSET=utf8;
And before executing this query make sure that users table exists and have column username;

Use single quote in enum instead of backquote. This worked for me:
CREATE TABLE events ( `id` mediumint unsigned not null auto_increment, `user` varchar(30) not null, `time` datetime not null, `duration` decimal(5,2) default 1.0, `title` tinytext not null, `location` text default null, `tag` ENUM('red','orange','yellow','green','blue','violet','brown','black') default null, PRIMARY KEY (`id`), FOREIGN KEY (`user`) references users (`username`) ) ENGINE=InnoDB DEFAULT CHARSET=utf8;

Change
`tag` ENUM(‘red’,’orange’,’yellow’,’green’,’blue’,’violet’,’brown’,’black’)
To
`tag` ENUM('red','orange','yellow','green','blue','violet','brown','black')
Use '' in case of ‘’ .

Trouble getting my primary and foreign key to work

I keep getting errors when I try to run the relational part of the database to pull the 3 columns in the relation table from the customer table and bill table.

ALTER TABLE `bill` ADD CONSTRAINT `b_total` FOREIGN KEY (`b_total`) REFERENCES `relationaltable`(`b_total`) ON DELETE RESTRICT ON UPDATE RESTRICT;
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

MySQL query error #1064?

I'm trying to import my old database but this gave me some errors what makes it impossible im also searching on google for 30 minuts and i can't find any solution?
SQL-query:
CREATE TABLE `UG_blogs` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`catid` int(11) NOT NULL,
`ownerid` int(11) NOT NULL,
`content` text NOT NULL,
`date` datetime NOT NULL DEFAULT TIMESTAMP,
PRIMARY KEY (`id`), KEY id(`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
MySQL meldt: Documentatie
#1064 - You have an error in your SQL syntax; check the manual that corresponds to your MariaDB server version for the right syntax to use near '
PRIMARY KEY (`id`), KEY id(`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT C' at line 6
The correct default value is CURRENT_TIMESTAMP:
CREATE TABLE `UG_blogs` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`catid` int(11) NOT NULL,
`ownerid` int(11) NOT NULL,
`content` text NOT NULL,
`date` datetime NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`id`),
KEY id(`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
The SQL Fiddle is here.
EDIT:
You must be using an old-ish version of MySQL (okay, not that old, just pre-5.6). Well, you can't default a datetime value (without a trigger), so you have to live with a TIMESTAMP value and learn to love the timestamp functions:
CREATE TABLE `UG_blogs` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`catid` int(11) NOT NULL,
`ownerid` int(11) NOT NULL,
`content` text NOT NULL,
`date` TIMESTAMP NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`id`),
KEY id(`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
First solution : change datatype into timestamp like this
CREATE TABLE `UG_blogs` (
`id` int(11) NOT NULL AUTO_INCREMENT,
`catid` int(11) NOT NULL,
`ownerid` int(11) NOT NULL,
`content` text NOT NULL,
`date` timestamp NOT NULL DEFAULT CURRENT_TIMESTAMP,
PRIMARY KEY (`id`),
KEY id(`id`)
) ENGINE=MyISAM AUTO_INCREMENT=3 DEFAULT CHARSET=latin1;
The problem is : The Timestamp data type has a range of 1970-01-01 00:00:01 UTC to 2038-01-19 03:14:07.
So the second solution is, don't change datetime datatype into timestamp. But you need a trigger to set default value.

#1452 - Cannot add or update a child row: a foreign key constraint fails ... Jutts

I have created tables in MySQL Workbench as shown below :
Categories Table
CREATE TABLE IF NOT EXISTS `categories` (
`categoryId` int(11) primary key auto_incremnt NOT NULL,
`categoryName` varchar(200) DEFAULT NULL,
`categoryDescription` varchar(200) DEFAULT NULL,
`categoryPicture` varchar(100) DEFAULT NULL,
`PostDate` varchar(255) NOT NULL,
`status` varchar(10) NOT NULL DEFAULT '1',
`LastInsertID` int(11) NOT NULL
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=45 ;
Products Table
CREATE TABLE IF NOT EXISTS `products` (
`proId` int(11) NOT NULL,
CONSTRAINT `categoryId` FOREIGN KEY (`categoryId`) REFERENCES `categories` (`categoryId`) ,
`proName` varchar(100) DEFAULT NULL,
`proPath` varchar(90) DEFAULT NULL,
`proPrice` float DEFAULT NULL,
`proQuantity` decimal(38,0) DEFAULT NULL,
`proImage` varchar(100) DEFAULT NULL,
`PostDate` varchar(50) NOT NULL,
`status` int(11) NOT NULL DEFAULT '1'
) ENGINE=InnoDB DEFAULT CHARSET=latin1 AUTO_INCREMENT=5 ;
I'm having a bit of a strange problem, I'm trying to add a foreign key
to one table that references another, but it is failing for some
reason. With my limited knowledge of MySQL, the only thing that could
possibly be suspect is that there is a foreign key on a different
table referencing the one I am trying to reference.
Please help me out as soon as possible .
Thanks in advance
You should create the categoryId column before assigning it in a foreign key,
categoryId int(11) NOT NULL,
CREATE TABLE IF NOT EXISTS `products` (
`proId` INT(11) NOT NULL,
`categoryId` INT ,
`proName` VARCHAR(100) DEFAULT NULL,
`proPath` VARCHAR(90) DEFAULT NULL,
`proPrice` FLOAT DEFAULT NULL,
`proQuantity` DECIMAL(38,0) DEFAULT NULL,
`proImage` VARCHAR(100) DEFAULT NULL,
`PostDate` VARCHAR(50) NOT NULL,
`status` INT(11) NOT NULL DEFAULT '1',
FOREIGN KEY (`categoryId`) REFERENCES `categories` (`categoryId`)
) ENGINE=INNODB DEFAULT CHARSET=latin1 AUTO_INCREMENT=5 ;

MySQL Error Number 150 when creating Table with Foreign Key

I am having an issue creating a new table in my database. I've seen that the error code it is returning is to do with Foreign Key constraints.
I checked to ensure that the data type of the foreign key in the new table matched the data type of the primary key in the other table. They are both int(11).
However I am still getting an error. Am I missing something? This is my SQL script for creating the new table:
CREATE TABLE `regular_features` (
`id` INT(11) NOT NULL AUTO_INCREMENT,
`name` VARCHAR(200) DEFAULT NULL,
`day` VARCHAR(200) DEFAULT NULL,
`description` TEXT DEFAULT NULL,
`programme_id` INT(11) NOT NULL,
PRIMARY KEY (`id`),
FOREIGN KEY (`programme_id`) REFERENCES directoryprogramme(id)
) ENGINE=INNODB DEFAULT CHARSET=utf8;
This is the original table containing the primary key:
CREATE TABLE `directoryprogramme` (
`id` INT(11) NOT NULL AUTO_INCREMENT,
`name` VARCHAR(250) NOT NULL,
`broadcast_time` VARCHAR(100) NOT NULL,
`description` TEXT NOT NULL,
`days` VARCHAR(150) NOT NULL,
`contributors` VARCHAR(250) NOT NULL,
`directorycompany_id` INT(11) NOT NULL,
`directorycontact_id` VARCHAR(250) NOT NULL,
`facebook_link` VARCHAR(250) DEFAULT NULL,
`twitter_link` VARCHAR(250) DEFAULT NULL,
`wikipedia_link` VARCHAR(250) DEFAULT NULL,
`web` VARCHAR(250) DEFAULT NULL,
`imageextension` VARCHAR(10) DEFAULT NULL,
`type` VARCHAR(20) NOT NULL DEFAULT 'other',
PRIMARY KEY (`id`)
) ENGINE=MYISAM AUTO_INCREMENT=1161 DEFAULT CHARSET=utf8;
The Foreign Key will be the id of directoryprogramme
The problem is the last line of your create statement:
ENGINE=INNODB DEFAULT CHARSET=utf8;
You mix MYISAM in ald table with INNODB in your new table.
That doesn't work.
Chnage the engine in your new table to MYISAM and it works.

I can't figure what's going on, any advice?
Remove the comma after UNIQUE KEY 'atom_id' ('atom_id'), in line 11
UNIQUE KEY `atom_id` (`atom_id`),
^
Try losing the ","
