MYSQL Error 1064 in Primary and Unique Keys - mysql

Question

Good day. I am trying to add a suppliers table on my database and when i try to save, it throws this error.
1064 - 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 '0) NOT NULL , PRIMARY KEY (supp_id), UNIQUE supp_name (supp_name))' at line 1
I have attached my SQL statement.
CREATE TABLE `project_inv`.`suppliers` (
`supp_id` INT(11) NOT NULL AUTO_INCREMENT ,
`supp_name` VARCHAR(255) NOT NULL ,
`supp_addr` VARCHAR(300) NOT NULL ,
`supp_phone` INT(20) NOT NULL ,
`supp_email` VARCHAR(255) NOT NULL ,
`supp_notes` VARCHAR(1000) NOT NULL ,
`status` ENUM(0) NOT NULL ,
PRIMARY KEY (`supp_id`),
UNIQUE `supp_name` (`supp_name`)
) ENGINE = InnoDB;
I think its something with my UNIQUE key but i really can't figure out what the error is. Any form of help will be appreciated. Thanks

Answer 1

It is not about the PRIMARY or UNIQUE declaration, but about ENUM(): it expects string literals, so you would need to surround the values in the list with single quotes:
CREATE TABLE `project_inv`.`suppliers` (
`supp_id` INT(11) NOT NULL AUTO_INCREMENT ,
`supp_name` VARCHAR(255) NOT NULL ,
`supp_addr` VARCHAR(300) NOT NULL ,
`supp_phone` INT(20) NOT NULL ,
`supp_email` VARCHAR(255) NOT NULL ,
`supp_notes` VARCHAR(1000) NOT NULL ,
`status` ENUM('0') NOT NULL ,
PRIMARY KEY (`supp_id`),
UNIQUE `supp_name` (`supp_name`)
) ENGINE = InnoDB;
However having a non-nullable ENUM() column with just one value allowed makes little sense - basically you are forcing every row to have the same value ('0'). So either add more values to the list... or just remove the column.

try like below by using string inside enum i used 'N' instated 0
CREATE TABLE `project_inv`.`suppliers` (
`supp_id` INT(11) NOT NULL AUTO_INCREMENT ,
`supp_name` VARCHAR(255) NOT NULL ,
`supp_addr` VARCHAR(300) NOT NULL ,
`supp_phone` INT(20) NOT NULL ,
`supp_email` VARCHAR(255) NOT NULL ,
`supp_notes` VARCHAR(1000) NOT NULL ,
`status` ENUM('N') NOT NULL ,
PRIMARY KEY (`supp_id`),
UNIQUE `supp_name` (`supp_name`)
) ENGINE = InnoDB;
