Vim用来当SQL Server Client?

最近迷上了Vim 了，感觉它有无穷无尽的玩法。那么它可以用来简单的查oracle 数据库吗？因为有一些现场只有ssh远程，如果直接在命令行 sqlplus用来查，总感觉体验不是很好。如果可以使用vim插件来查数据库会不会体验好一些呢？

vim-dadbod

Dadbod是一个用于与数据库交互的Vim插件。 项目地址： https://github.com/tpope/vim-dadbod

vim-dadbod-ui

基于 vim-dadbod有图形化界面，比较好上手。 安装 我使用的是：Vundle插件管理器

Plugin 'kristijanhusak/vim-packager'
Plugin 'tpope/vim-dadbod'
Plugin 'kristijanhusak/vim-dadbod-ui'

:PluginList安装就搞定了。

数据源配置。 比如：

vim ~/.vim/vimrc

这里我以oracle为例。

let g:dbs = [
\ { 'name': 'centos', 'url': 'oracle://usr_sg:apexsoft@CentOS' },
\ { 'name': 'centos2', 'url': 'oracle:usr_sg/apexsoft@172.16.184.5:1521/orcl' }
\ ]

第一种是连接 tnsnames.ora 中配置的服务的形式。 第二种是直接连接的方式。 个人感觉第二种方式更简单直接一些。

查sql

:DBUI打开界面。 输入sql 在执行 :w后就会执行查询操作了。

使用 nerd fonts图标

vim的配置文件中加入以下内容，开启图标显示

let g:db_ui_use_nerd_fonts=1

显示效果确实要好一些了。

这下有图标了。

如果图标显示乱码，说明字体没有安装完成，可以参考《macOS中SpaceVim搭建java开发环境》 搜索 “字体乱码问题”

USAGE                                           *dadbod* *:DB*

:DB [url]               Start an interactive database console.  Uses
                        dispatch.vim's |:Start| if available.

:DB [url] {cmd}         Run {cmd} on the selected database and show the
                        results in a preview window.

:{range}DB [url]        Run the lines referenced by {range} on the selected
                        database and show the results in a preview window.

:DB [url] < {file}      Run the given {file} on the selected database and show
                        the results in a preview window.

:DB {var} = {url}       Assign the canonicalization of {url} to a |g:|, |w:|,
                        |t:|, |b:|, or environment variable.

:DB [url] :{command}    Run the Vim command {command} with the given URL set
                        as the default.  This is mainly useful with
                        |g:dadbod_manage_dbext|.

In the preview window, you can press "R" to rerun, "r" to interactively rerun,
or "q" to close the window.

URLS                                            *dadbod-urls*

URLs are adapter specific but generally take one of two formats:
>
    adapter://[user[:password]@][host][:port]/[database]
    adapter:[database]

A complete reference is below under |dadbod-adapters|, but a few examples should
mostly get the point across:
>
    postgresql://postgres:secret@remote-host/test
    mysql://root@localhost/test
    sqlite:db.sqlite3
    mongodb:///admin
    redis:///
<
Additionally, one can give:

* A Vim variable (e.g., g:foo, w:bar, t:baz, b:quux) or environment variable
  (e.g., $DATABASE_URL) containing a URL.
* File name of a supported database file (e.g. ~/db.sqlite3). Relative paths
  must start with "./", and spaces must be %20 URL encoded (NOT backslash
  escaped).

VARIABLES                                       *dadbod-variables*

If a |w:|, |t:|, |b:|, |g:|, or $ENVIRONMENT variable is given as a URL, its
value will be used.  Additionally, if no URL is given, the first of w:db,
t:db, b:db, $DATABASE_URL, and g:db will be used.  Suggested uses:

* w:db is best set interactively.
* b:db is most useful when set from an |autocommand|.
* g:db and other globals can be set in your |vimrc| or other startup file.
* $DATABASE_URL and other environment variables are easy to set externally.

Set a variable with |:let|, or use |:DB| to normalize the URL first:
>
    :DB w:db = adapter://...

    dbext:type=[:=][...]
    dbext:profile=[...]
<
For supported adapters, dbext modelines and profiles can be used directly.

An empty path portion uses an in-memory database, which is how osquery is
typically invoked.

Redis doesn't have a username, so use a dummy one in the URL if a password is
required.
