firebird的sql代码不能编译

Question

我尝试使用Firebird包中的isql工具创建简单的数据库时出现奇怪的错误。

创建表的相同代码适用于其他名称的表。 我试过了，没有引号围绕字段和表名，没有成功。

它是Firebird 2.5服务器版本。

的代码我试图执行：

我不明白为什么它不可能创造第一个表“RULES”，尽管这些命令与其他表相似。 即使没有所有的触发器和外键（alter table ..）我也会遇到最后一个错误。 它说“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，它可能是我错过了或混合了一些东西，但我试图编译过多的更改，仍然出现错误。 我发现或多或少相似的代码在这里

和我能够编译它没有问题。 有人能指出我的方向是正确的还是以另一种方式表明它是如何完成的？

你在PK约束结束的unnessesary逗号：

CONSTRAINT PK_RULE_ID 
PRIMARY KEY (RULE_ID), 

所以场或约束的解析器expexts定义，但它发现“）”。删除逗号，你应该没问题。
