printing - 如何打印 Firebird 触发器？

Question

我想打印 firebird 数据库中所有触发器的内容。

我有一个firebird数据库，有20个字段，56个触发器，每个触发器大概10到20行sql代码。是否有任何 gui 软件能够做到这一点，或者一个 sql 命令能够选择所有触发器，然后将它们导出为 txt 文件？

所有触发器都可以从 RDB$TRIGGERS 表中找到。

您可以使用此 SQL 查询来获取有关触发器的信息:

SELECT RDB$TRIGGER_NAME AS trigger_name,
       RDB$RELATION_NAME AS table_name,
       RDB$TRIGGER_SOURCE AS trigger_body,
       CASE RDB$TRIGGER_TYPE
        WHEN 1 THEN 'BEFORE'
        WHEN 2 THEN 'AFTER'
        WHEN 3 THEN 'BEFORE'
        WHEN 4 THEN 'AFTER'
        WHEN 5 THEN 'BEFORE'
        WHEN 6 THEN 'AFTER'
       END AS trigger_type,
       CASE RDB$TRIGGER_TYPE
        WHEN 1 THEN 'INSERT'
        WHEN 2 THEN 'INSERT'
        WHEN 3 THEN 'UPDATE'
        WHEN 4 THEN 'UPDATE'
        WHEN 5 THEN 'DELETE'
        WHEN 6 THEN 'DELETE'
       END AS trigger_event,
       CASE RDB$TRIGGER_INACTIVE
        WHEN 1 THEN 0 ELSE 1
       END AS trigger_enabled,
       RDB$DESCRIPTION AS trigger_comment
  FROM RDB$TRIGGERS
