[20170617]vim中调用sqlplus.txt
--//以前写过一篇emacs下调用sqlplus的文章,一直想学emacs,受限制自己掌握vim,对学习它没有兴趣,原链接如下:
--//http://blog.itpub.net/267265/viewspace-1309032/
--//实际上vim也有插件连接数据库,我觉得不好用,一直没这样用.
--//今天在整理vim相关设置时,发现我自己以前也定义一些方法,自己也拿出来分享:
noremap <Leader>q1 Yp!!sqlplus -s scott/btbtms@test01p<CR>
noremap <Leader>q2 Yp!!sqlplus -s sys/btbtms@test01p as sysdba<CR>
vnoremap ;q1 "ay<ESC>gv!sqlplus -s scott/btbtms@test01p<CR>
vnoremap ;q2 "by<ESC>gv!sqlplus -s sys/btbtms@test01p as sysdba<CR>
--//将以上信息放在vim配置文件中,注意打入命令一定要正确,后面要有分号.当然错误不执行就是了.
--//根据自己需要修改数据库连接串以及用户,口令信息.当然这样存在安全问题.^_^.
select * from dept;
--//移动到哪一行,打入\q1

--//这种方式的缺点就是必须将sql语句写一行内.
--//也可以这样操作,按v或者V,选中文本,进入v模式,然后打入;q1.
--//提醒一下,如果使用shift+方向键选择的进入的是"选择模式",按ctrl+g就可以切换为"可视模式"

--//这样显示,缺点就是打入的sql语句消失了.你可以先copy 2份再执行.

--//另外我还把内容放在寄存器a,b,可以使用"ap ,"bp取出.
--//提醒注意一点执行的语句不要是dml语句,比如insert,update,delete语句,还有truncate语句.因为缺省就是退出就是commit.存在一定的风险.
--//执行select语句一般问题不大.作为测试学习也应该避免dml语句,不然把这种习惯带到生产库出问题就麻烦了.
--//补充1点,还可以适当设置大一点linesize,这样避免出现折行想象.当然还有致命的缺点,每次执行都要打开与关闭数据库的连接.而且连接串是写死的.
--//附上checkpoint.sql脚本
