firebird 的 sql 代码无法编译

Question

我在尝试使用 Firebird 包中的 isql 工具创建简单数据库时遇到奇怪的错误。

创建表的相同代码适用于具有其他名称的其他表。 我尝试过在字段和表名周围使用或不使用引号，但没有成功。

这是Firebird 2.5服务器版本。

我尝试执行的代码:

CREATE DATABASE 'localhost:C:\fuzzdb.fdb' user 'SYSDBA' password 'masterkey'

我不明白为什么无法创建第一个表“RULES”，尽管命令与其他表类似。 即使没有所有触发器和外键(更改表..)，我至少会收到最后一个错误。 它显示“索引 FK_LINK_FRL_FS 中的未知列”，但没有提及其他类似的索引表。

我刚刚开始使用数据库，可能是我错过或混合了一些东西， 但我尝试进行太多更改进行编译，但仍然出现错误。 我在这里找到了或多或少相似的代码

我能够毫无问题地编译它。 有人能给我指出正确的方向或者展示它是如何以另一种方式完成的吗？

Answer 1

PK 约束末尾有一个不必要的逗号:

CONSTRAINT PK_RULE_ID
PRIMARY KEY (RULE_ID),

因此解析器解释了字段或约束的定义，但它找到了“)”。删除逗号就可以了。
