Question

我想用Jooq生成一些类。

Jooq版本：3.8.2 火鸟版本：2.5 JDBC-Firebird-Driver：2.1.6

这是我的Config.xml：

   <?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<configuration xmlns="http://www.jooq.org/xsd/jooq-codegen-3.7.0.xsd">
    <jdbc>
        <driver>org.firebirdsql.jdbc.FBDriver</driver>
        <url>jdbc:firebirdsql:localhost/3050://var/lib/firebird/2.5/data/db.gdb?encoding=ISO8859_1</url>
        <user>sysdba</user>
        <password>masterkey</password>
    </jdbc>
    <generator>
        <name>org.jooq.util.JavaGenerator</name>
        <database>
            <name>org.jooq.util.firebird.FirebirdDatabase</name>
            <includes>.*</includes>
            <excludes>RDB\$.*|MON\$.*|SEC\$.*</excludes>
            <inputSchema></inputSchema>
        </database>
        <generate>
            <pojosEqualsAndHashCode>true</pojosEqualsAndHashCode>
            <pojos>true</pojos>
        </generate>
        <target>
            <packageName>models.gen</packageName>
            <directory>./app</directory>
        </target>
    </generator>
</configuration>

如果我运行jooq，我会收到SQL错误：

    SQL error code = -206
Column unknown
RDB$PROCEDURES.RDB$PROCEDURE_TYPE
At line 1, column 208

我的Firebird DB中确实不存在RDB $ PROCEDURE_TYPE列。

我该如何解决这个问题？

Answer 1

列RDB$PROCEDURE_TYPE是在Firebird 2.0（On-Disk-Structure（ODS）11.0）中引入的。从它的外观来看，你的数据库是ODS 10（Interbase 6 / Firebird 1.0）。要在数据库中获取此列，您需要通过备份数据库并还原它来升级ODS。这会将您的数据库升级到ODS 11.2（Firebird 2.5）。

为什么我在使用jooq的Firebird中获得列未知异常？
