Всем привет!
У меня падает запрос с ошибкой:
GET
localhost:8080/api/groups
java.sql.SQLSyntaxErrorException: 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 'groups group0_ order by group0_.created_at desc limit 30' at line 1
Не могу понять, где я ошибся(Кроме того, что не использую JDBC)
таблица:
CREATE TABLE `groups`
(
`id` bigint(19) unsigned NOT NULL AUTO_INCREMENT,
`name` varchar(255) NOT NULL,

`created_by` bigint(19) unsigned DEFAULT NULL,
`updated_by` bigint(19) unsigned DEFAULT NULL,
PRIMARY KEY (`id`)
) ENGINE = InnoDB
AUTO_INCREMENT = 1
DEFAULT CHARSET = utf8;
