#1064 You have an error in your SQL syntax; - mysql

Question

I'm getting the following error when I try to create a TABLE in SQL.
The version of phpMyAdmin I'm using it 4.2.7.1 which says it's up to date.
Can anyone help? I can't spot an error? I have looked in similar questions relating to error 1064, but no joy

Answer 1

Remove single quote characters from field names

Answer 2

You need to use back-ticks ` (next to the 1 key on my keyboard) instead of ' quotes. This works for me:
CREATE TABLE `categories` (
`id` SMALLINT UNSIGNED NOT NULL AUTO_INCREMENT,
`category` VARCHAR(45) NOT NULL,
PRIMARY KEY (`id`),
UNIQUE INDEX `category_UNIQUE` (`category` ASC)
) ENGINE = InnoDB DEFAULT CHARSET=utf8;

Answer 3

Replace ' characters that surround table names and field names by `.
There are some more syntax errors that will appear then - for example there are unneeded parentheses around 'users' table.
Also when you create 'orders' table, it has a foreign key on users, but users are declared later.
