表的结构:

CREATE TABLE `tag` (  
    `idtag` tinyint(4) NOT NULL AUTO_INCREMENT,  
    `codigo` varchar(3) NOT NULL,  
    PRIMARY KEY (`idtag`),  
    UNIQUE KEY `codigo_UNIQUE` (`codigo`)
) ENGINE=InnoDB AUTO_INCREMENT=127 DEFAULT CHARSET=utf8

需要帮助谢谢。

最佳答案

signed TINYINT 可以包含从 -128 到 127 的数字。您的表中很可能已经有 127 行，因此您的主键列不能包含更多。更改您的数据类型 SMALLINT UNSIGNED (0-65535) MEDIUMINT UNSIGNED (0-16777215) 或只是 INT UNSIGNED (0-4294967295) - 那最后一个应该绰绰有余
