列出OpenBSD数据库/sqlports sqlite3数据库的表和字段

如何开始使用

sqlite3

数据库

例如，有一个包含关于OpenBSD端口的各种信息；我已经在OpenBSD 5.2上安装了它，根据

/var/db/pkg/sqlports-2.3p0/+CONTENTS

，它创建的唯一文件是

/usr/local

中的

share/sqlports

% file /usr/local/share/sqlports
/usr/local/share/sqlports: SQLite 3.x database

---

我如何知道它有哪些表，每个表有哪些字段？

下面的SQL查询似乎可以完成这项工作：

cnst你的回答是对的。您也可以使用。命令。 例如，列出您输入的数据库.databases和获取表.tables

请尝试。帮助以获取更多可能的命令

编辑：对于OpenBSD pkg信息，您可以在下的目录中找到文件系统友好格式的文件

---

/var/db/pkg/

yeap，

.tables

工作得很好，但它不显示字段，只显示表。我怎样才能得到田地？另外，

/var/db/pkg/

将只包含已安装的软件包，因此它根本不会删除它。也请检查这个SO问题（我更喜欢布拉格语的答案）。最后，我推荐的管理pkgstuff的方法是从CVS签出/usr/ports，然后通过查看makefile和PLISTS，您可以获得所需的所有信息。最后，我想您已经阅读了pkg_信息的主页：）
