[20170617]vim中調用sqlplus.txt

--//以前寫過一篇emacs下調用sqlplus的文章,一直想學emacs,受限制自己掌握vim,對學習它沒有興趣,原連結如下:
--//http://blog.itpub.net/267265/viewspace-1309032/

--//實際上vim也有外掛程式串連資料庫,我覺得不好用,一直沒這樣用.

--//今天在整理vim相關設定時,發現我自己以前也定義一些方法,自己也拿出來分享:

noremap  <Leader>q1 Yp!!sqlplus -s scott/[email protected]<CR>
noremap  <Leader>q2 Yp!!sqlplus -s sys/[email protected] as sysdba<CR>
vnoremap  ;q1       "ay<ESC>gv!sqlplus -s scott/[email protected]<CR>
vnoremap  ;q2       "by<ESC>gv!sqlplus -s sys/[email protected] as sysdba<CR>

--//將以上資訊放在vim設定檔中,注意打入命令一定要正確,後面要有分號.當然錯誤不執行就是了.
--//根據自己需要修改資料庫連接串以及使用者,口令資訊.當然這樣存在安全問題.^_^.

select * from dept;
--//移動到哪一行,打入\q1

--//這種方式的缺點就是必須將sql語句寫一行內.
--//也可以這樣操作,按v或者V,選中文本,進入v模式,然後打入;q1.
--//提醒一下,如果使用shift+方向鍵選擇的進入的是"選擇模式",按ctrl+g就可以切換為"可視模式"

select
*
from
dept;

--//這樣顯示,缺點就是打入的sql語句消失了.你可以先copy 2份再執行.

--//另外我還把內容放在寄存器a,b,可以使用"ap ,"bp取出.

--//提醒注意一點執行的語句不要是dml語句,比如insert,update,delete語句,還有truncate語句.因為預設就是退出就是commit.存在一定的風險.
--//執行select語句一般問題不大.作為測試學習也應該避免dml語句,不然把這種習慣帶到生產庫出問題就麻煩了.
--//補充1點,還可以適當設定大一點linesize,這樣避免出現折行想象.當然還有致命的缺點,每次執行都要開啟與關閉資料庫的串連.而且串連串是寫死的.

--//附上checkpoint.sql指令碼
