我现在正在尝试创建一个SQL Server数据库但是我遇到的错误似乎无法解决。我是一名学生，他试图通过我在互联网上找到的作业来改善自己，这个让我难过。以下是我与数据库部分相关的错误
Msg 547，Level 16，State 0，Line 221

例如，大多数公司不允许在Customer表中不存在CustomerID的情况下输入订单。大多数学校不允许在学生和班级表中各自的身份证不同的情况下发生学生级别的学习。
答案 1 :(得分：0)
如果按此顺序运行这些查询，则首先将数据放入TPatients，然后放入TRandomCodes。但是在创建外键约束的第一部分中，为TPatients表中的intRandomCodeID列添加外键约束，以引用TRandomCodes表中的intRandomCodeID。当您将数据放入TPatients表时，服务器会检查TRandomCodes表中是否存在intRandomCodeID列的数据，因为存在约束。当服务器发现不存在这样的行（数据）时，它会抛出错误。
