　　二、嵌入sql语句及rman到shell脚本

　　1、直接将sql语句嵌入到shell脚本

oracle@SZDB:~> more get_dept_2.sh
#!/bin/bash
# Author : Robinson Cheng
# Blog : http://blog.csdn.net/robinson_0612

# set environment variable

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

export ORACLE_SID=CNMMBO
sqlplus -S /nolog <<EOF     #EOF在此表示当输入过程中碰到EOF后，整个sql脚本输入完毕
connect scott/tiger
spool /tmp/dept.lst
set linesize 100 pagesize 80
select * from dept;
spool off;
exit;                       #退出sqlplus 环境
EOF
exit                        #推出shell脚本

#授予脚本执行权限
oracle@SZDB:~> chmod u+x get_dept_2.sh

#执行shell脚本
oracle@SZDB:~> ./get_dept_2.sh

    DEPTNO DNAME          LOC
---------- -------------- -------------
        10 ACCOUNTING     NEW YORK
        20 RESEARCH       DALLAS
        30 SALES          CHICAGO
        40 OPERATIONS     BOSTON

　　2、直接将sql语句嵌入到shell脚本（方式二，使用管道符号>代替spool来输出日志）

oracle@SZDB:~> more get_dept_3.sh
#!/bin/bash

# set environment variable

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

export ORACLE_SID=CNMMBO
sqlplus -S /nolog 1>/users/oracle/dept.log 2>&1 <<EOF
connect scott/tiger
set linesize 80 pagesize 80
select * from dept;
exit;
EOF
cat /users/oracle/dept.log
exit

#另一种实现方式，将所有的sql语句输出来生成sql脚本后再调用
oracle@SZDB:~> more get_dept_4.sh
#!/bin/bash

# set environment variable

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

export ORACLE_SID=CNMMBO
echo "conn scott/tiger
select * from dept;
exit;" >/users/oracle/get_dept.sql
sqlplus -silent /nolog @get_dept.sql 1>/users/oracle/get_dept.log 2>&1
cat get_dept.log
exit

　　3、将rman脚本嵌入到shell脚本

oracle@SZDB:~> more rman_bak_2.sh
#!/bin/bash

# set environment variable

if [ -f ~/.bashrc ]; then
. ~/.bashrc
fi

export ORACLE_SID=CNMMBO
$ORACLE_HOME/bin/rman log=/users/oracle/bak/rman.log <<EOF
connect target /

}
EXIT;
EOF
exit
