sql - INSERT 语句与 FOREIGN KEY 约束冲突。数据库发生冲突

Question

我已经遇到这个问题几个小时了。在 SQL Server 中，我运行了以下查询:

INSERT INTO USERS_AVATAR(userId, avatId) VALUES ('1', '213');
INSERT INTO USERS_AVATAR(userId, avatId) VALUES ('2', '312');

但显示的消息显示:

Msg 547, Level 16, State 0, Line 1
The INSERT statement conflicted with the FOREIGN KEY constraint "FKUSERS_AVAT731248". The conflict occurred in database "gk314", table "gk314.USERS", column 'userId'.

Msg 547, Level 16, State 0, Line 2
The INSERT statement conflicted with the FOREIGN KEY constraint "FKUSERS_AVAT731248". The conflict occurred in database "gk314", table "gk314.USERS", column 'userId'.

请帮忙!

Answer 1

在将用户 ID 1 和 2 插入 USERS_AVATAR 之前，必须先将它们插入表 USERS 中。这就是 FOREIGN KEY 约束所需要的。
