Question

尝试使用Firebird包中的isql工具创建一个简单的数据库时，我遇到了奇怪的错误。

创建表的相同代码适用于具有其他名称的其他表。我已尝试使用和不包含字段和表名称的引号，但没有成功。

它是Firebird 2.5服务器版本。

我正在尝试执行的代码：

SET SQL DIALECT 3;
SET NAMES UTF8;
CREATE DATABASE 'localhost:C:\fuzzdb.fdb' user 'SYSDBA' password 'masterkey'
DEFAULT CHARACTER SET UTF8;

CREATE TABLE RULES (
RULE_ID INTEGER NOT NULL,

PRIMARY KEY (RULE_ID),

ALTER TABLE LINK_FRL_RL

CREATE GENERATOR GEN_RULE_ID;
CREATE GENERATOR GEN_VAR_ID;
CREATE GENERATOR GEN_FS_ID;
CREATE GENERATOR GEN_FRULE_ID;

我不明白为什么创建第一个表“RULES”是不可能的，尽管这些命令与其他表类似。即使没有所有触发器和外键（alter table ..），我也会在最后一次错误中获取。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，可能是我错过了或混合了一些东西，但我尝试编译太多的更改仍然会出错。我在这里找到了或多或少类似的代码

我能够毫无问题地编译它。有人可以指出我正确的方向或以另一种方式展示它是如何完成的吗？

PK约束的末尾有一个不必要的逗号：

CONSTRAINT PK_RULE_ID
PRIMARY KEY (RULE_ID),

因此解析器需要定义字段或约束，但它会找到“）”。删除逗号，你应该没问题。
