Question

The following code is a minimal example from a larger query generated by a backup script (possibly using mysqldump). It results in an error and I don’t know why. Who can help?

CREATE TABLE `tl_custom_tandem_lang` (
    `id` varchar(2) COLLATE latin1_german2_ci NOT NULL,
    PRIMARY_KEY (`id`),
    UNIQUE KEY `id` (`id`)
);

Produces following error:

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 ‘(id), UNIQUE KEY id (id) )’ at line 3

Answer 1

it should be PRIMARY KEY not PRIMARY_KEY (remove the underscore to make it work.)

CREATE TABLE `tl_custom_tandem_lang` 
(
    `id` varchar(2) COLLATE latin1_german2_ci NOT NULL,
    PRIMARY KEY (`id`),
    UNIQUE KEY `tb_unique` (`id`)
);
