Question

我正在尝试使用2个表创建简单数据库，首先是用户信息，第二个用于上传，因为它是教师的项目，我有一些任务......一个是使用外键。

但我无法弄清楚如何做到这一点，当我用phpMyAdmin做的时候一切正常，但是当我导出它并将它放在我的服务器上时我有一些错误;请帮帮我。

  `UserID` int(11) NOT NULL AUTO_INCREMENT,

  `password` varchar(32) COLLATE utf8_bin NOT NULL,
  `email` varchar(32) COLLATE utf8_bin NOT NULL,
  `telefon` varchar(16) COLLATE utf8_bin NOT NULL,
  PRIMARY KEY (`UserID`)

ALTER TABLE `slike`
  ADD CONSTRAINT `slike_ibfk_1` FOREIGN KEY (`UserID`) REFERENCES `korisnici` (`UserID`);

错误：

第77行的错误1072（42000）：表格中不存在关键列'UserID'

如果有人能修复我的代码并解释，我将不胜感激。

编辑新错误：

第42行的错误1054（42S22）：“字段列表”中的未知列'UserID'

当我插入一些东西时：

SET FOREIGN_KEY_CHECKS=0;
SET SQL_MODE = "NO_AUTO_VALUE_ON_ZERO";
SET time_zone = "+00:00";
