一个mysql错误

表结构，id，自增主键；interval，int型；luckynum，int型；

INSERT INTO t_gua_parameter (interval, luckynum) VALUES (2, 3);

报错

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 'inter
val, luckynum) VALUES (2, 3)' at line 1

用navicat手动插入一条数据，复制命令

INSERT INTO `t_gua_parameter` (`interval`, `luckynum`) VALUES (2, 3);

略加修改

INSERT INTO t_gua_parameter (`interval`, `luckynum`) VALUES (2, 3);

正常运行

原因不明
