Question

我正在尝试将在mySql工作台中创建的数据库导入phpMyAdmin（WAMP服务器），当我尝试导入它时，我收到错误：

MySQL said: Documentation
#1005 - Can't create table '.\mydb\team.frm' (errno: 121)

以下是执行的SQL脚本

对上面的评论进行更改（DATETIME到INT并创建唯一约束和索引名称）。作为一种安全的做法，在我们的组织中，我们始终将索引/约束命名为(table1Identifier)_(table2Identifier)_(constraintType) ...所以类似Log_Card_idx或Auth_Fixture_FK。只是一个想法。
