Question

我为用户创建了一个个人资料页面，但是我收到了这个错误：

致命错误：未捕获PDOException：SQLSTATE [HY000]：常规错误：1366不正确的整数值：第12行C：\ wamp64 \ www \ social_network \ classes \ DB.php中第1行的列'id''' （！）PDOException：SQLSTATE [HY000]：常规错误：1366不正确的整数值：''对于第12行C：\ wamp64 \ www \ social_network \ classes \ DB.php中第1行的列'id'

我确信我的\classes\DB.php是正确的，因为它连接到其他php文件。这是我正在使用的“个人资料页面”代码：

感谢您的时间。

常规错误：1366错误的整数值：''列'id'[...]

您正在尝试将字符串/ varchar值''（空字符串）保存到列'id'，这是一个整数类型。由于无法在整数列中保存字符串，因此会收到此错误消息。

由于它是AUTO_INCREMENT列，因此解决方案是根本不为此列提供值。您可以通过添加要填充的INSERT语句中的列来完成此操作。

INSERT INTO Table(colA, colB) VALUES (val1, val2);

这样，所有剩余的列都将获得默认值或AUTO_INCREMENT值。

不正确的整数值：''列'id'
