收割机地头教学:shell中操作sqlplus

shell中操作sqlplus2011-01-05 21:56一、最简单的shell里调用sqlplus.$ vi test1.sh#!/bin/bash
sqlplus -S /nolog > result.log < set heading off feedback off pagesize 0 verify off echo off
conn u_test/iamwangnc
select * from tab;
exit
EOF$ chmod +x test1.sh
$ ./test1.sh二、把sqlplus执行结果传递给shell方法一注意sqlplus段使用老板键`了, 赋变量的等号两侧不能有空格.$ vi test2.sh#!/bin/bash
VALUE=`sqlplus -S /nolog < set heading off feedback off pagesize 0 verify off echo off numwidth 4
conn u_test/iamwangnc
select count(*) from tab;
exit
EOF`
if [ "$VALUE" -gt 0 ]; then
        echo "The number of rows is $VALUE."
        exit 0
else
        echo "There is no row in the table."
fi$ chmod +x test2.sh
$ ./test2.sh三、把sqlplus执行结果传递给shell方法二注意sqlplus段使用 col .. new_value .. 定义了变量并带参数exit, 然后自动赋给了shell的$?$ vi test3.sh#!/bin/bash
sqlplus -S /nolog > result.log < set heading off feedback off pagesize 0 verify off echo off numwidth 4
conn u_test/iamwangnc
col coun new_value v_coun
select count(*) coun from tab;
exit v_coun
EOF
VALUE="$?"
echo "The number of rows is $VALUE."$ chmod +x test3.sh
$ ./test3.sh四、把shell程序参数传递给sqlplus$1表示第一个参数, sqlplus里可以直接使用, 赋变量的等号两侧不能有空格不能有空格.$ vi test4.sh#!/bin/bash
NAME="$1"
sqlplus -S u_test/iamwangnc < select * from tab where tname = upper('$NAME');
exit
EOF$ chmod +x test4.sh
$ ./test4.sh ttt五、为了安全要求每次执行shell都手工输入密码$ vi test5.sh#!/bin/bash
echo -n "Enter password for u_test:"
read PASSWD
sqlplus -S /nolog < conn u_test/$PASSWD
select * from tab;
exit
EOF$ chmod +x test5.sh
$ ./test5.sh六、为了安全从文件读取密码对密码文件设置权限, 只有用户自己才能读写.$ echo 'iamwangnc' > u_test.txt
$ chmod g-rwx,o-rwx u_test.txt
$ vi test6.sh#!/bin/bash
PASSWD=`cat u_test.txt`
sqlplus -S /nolog < conn u_test/$PASSWD
select * from tab;
exit
EOF$ chmod +x test6.sh
$ ./test6.sh--End--  自己试验的内容：#!/bin/sh

ps:解析Shell中，块的开始和结束
su - oracle -c "sqlplus username/password"<其中：
su： 切换用户
-： 使用orcale的环境设置
-c： 执行后面的命令
<：因为sqlplus要输入用户名和密码所以接下去的两行分别输入。
当第三行出现EOF的时候，shell认为输入结束；并将输入传递给sqlplus命令
eof可以是任何字符串 比如"laldf"那么当你输入单独一行laldf时"shell认为输入结束，但是必须表示块开始必须使用<<；
开始和结束要匹配这个符号“<<”后面的内容
举例子:
代码：
su - oracle -c "sqlplus username/password" <abc

//这个abc是shell用来识别的开始
此时屏幕显示：sqlplus username/password
然后你输入：user001
                     user001
遇见代码：abc                     ，表示结束            

今天在改一个脚本的时候突然遇到一个问题，SQLPLUS在登录的时候出现"<< is not matched "的错误

细细看来，原来是可以，经过改变以后只是位置不一样，改之前是在for循环的外面登录，改之后在
for循环内登录，但是我想也不应该影响才对的

改之前的登录执行方式：
sqlplus -s "username/password@alias" <TRUNCATE TABLE ZHJS_TP_UNIQUE_ID;
exit
EOF

改了好几个方式还是不行，到最后实在受不了，用google搜索得了，烦的，晕死了，不搜还好，一搜
结果就出来了，呵呵，在论坛上别人是这么说的：
The "END" tag to your so-called "here" document (started by the <needs to be at the left hand side. That means it must be placed at the start of 
line without any whitespace in front of it. 

好了，按照上面的方法，改成如下的方式就可以了，高兴死了.......
<TRUNCATE TABLE ZHJS_TP_UNIQUE_ID;
exit
EOF
