我在 mySQL 中收到了一些错误并且只出现了几个表格

Question

我对此有点陌生，我收到了一些错误，我的数据库 (phpmyadmin) 中只出现了 4 个表。你能帮忙吗？

我收到这些错误： 错误静态分析：

分析过程中发现 3 个错误。

需要逗号或右括号。（靠近位置 116 的“精度”）语句的意外开始。（在位置 160 的“8”附近）无法识别的语句类型。（在位置 163 的“NOT NULL”附近） SQL查询：复制

MySQL 说：文档

#1064 - 你的 SQL 语法有误；查看与您的 MariaDB 服务器版本对应的手册，了解在第 12

行 'for FOREIGN KEY(fk_DISTRIBUTORcompany_id) REFERENCES DISTRIBUTOR (company_id)...' 附近使用的正确语法

Answer 1

运行每次手动创建 table 到 mysql，这将有助于识别错误所在。然后根据需要更正代码。如果您在 table 创作上取得成功，那一个就可以正常工作。

您的 sql 代码中某处存在错误。调试它！

Answer 2

当您尝试在创建关系表之前添加约束时，通常会出现此错误。尝试创建所有表然后添加它们的键，约束如下：

CREATE TABLE CONTRACT
(
    contract_id int NOT NULL,
    date date NOT NULL,
    car_count int NOT NULL,
    price double precision NOT NULL,
    contract_status char (8) NOT NULL,
    fk_DISTRIBUTORcompany_id int NOT NULL,
    fk_CEOmobile_number int NOT NULL,
    CHECK(contract_status in ('accepted', 'declined', 'on hold')),
);    

ALTER TALBE `CONTRACT`
ADD PRIMARY KEY(contract_id),
ADD CONSTRAINT applies for FOREIGN KEY(fk_DISTRIBUTORcompany_id) REFERENCES DISTRIBUTOR (company_id),
    CONSTRAINT accept FOREIGN KEY(fk_CEOmobile_number) REFERENCES CEO (mobile_number)

其他表也一样。
