Question

MySQL

Good evening. Tell me what could be wrong if this error is
displayed 14.SELECT elems.* FROM `example`.`example2` elems WHERE 1 ORDER BY `id` DESC, `len` ASC LIMIT 0, 30
SELECT command denied to user ' example3'@'localhost' for table 'example2'

Answer 1

GRANT SELECT ON `пример`.`пример2` TO 'пример3'@'localhost'
