Question

我在运行此脚本时出现问题...每次尝试运行它时，我得到（2）无法为成员表创建表错误（1）和（1）对于会话表

我在俯瞰什么？

Answer 1

问题是您的外键约束引用了另一个表中未编制索引的列。将索引添加到Student。Parent_id和transactions。user_id允许我创建成员表。仔细检查它们指向索引列的所有外键约束。

Answer 2

引用列应该是唯一的。

表格test_db。member - ＆gt;参考test_db。Student（Parent_id）
表test_db。session - ＆gt;参考test_db。session_type（cost）
CREATE TABLE IF NOT NOT EXISTS test_db。table1（） ENGINE = InnoDB;

检查您的架构（主键，唯一键，外键）是否正确。
