java - 为什么我在使用 jooq 的 Firebird 中出现列未知异常？

Question

我想用 Jooq 生成一些类。

Jooq版本:3.8.2 Firebird 版本:2.5JDBC-Firebird-驱动程序: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，我会得到一个 SQL 错误:

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

RDB$PROCEDURE_TYPE 列在我的 Firebird 数据库中确实不存在。

我该如何解决这个问题？

Answer 1

RDB$PROCEDURE_TYPE 列在 Firebird 2.0(On-Disk-Structure (ODS) 11.0)中引入。从外观上看，您的数据库是 ODS 10 (Interbase 6/Firebird 1.0)。要在您的数据库中获取该列，您需要通过备份和恢复数据库来升级 ODS。这会将您的数据库升级到 ODS 11.2 (Firebird 2.5)。
