shell 与 sqlplus 交互

1、简单shell调用sqlplus

编写脚本

[oracle@localhost oracle_script]$

#!/bin/bash

# user env
source ~/.bash_profile

sqlplus -S /nolog > <<EOF

--set heading off feedback off pagesize 0verify off echo off

conn scott/tiger

select * from emp where empno= 7369;

exit

EOF

备注：这里注意要加上source ~/.bash_profile环境变量，否则找不到SQLPLUS命令，

或者直接用export ...... oracle路径也可

修改脚本权限

[oracle@localhost oracle_script]$ chmod +x

[oracle@localhost oracle_script]$ ll

总计 4

-rwxr-xr-x 1 oracle oinstall 154 01-1308:59

执行脚本

[oracle@localhost oracle_script]$./

查看结果

[oracle@localhost oracle_script]$

EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO

---------- ---------- --------- ---------- --------- ---------- ---------- ----------

7369 SMITH CLERK 7902 17-DEC-80 800 20

2、Sqlplus返回值给Shell(一)

方式一：用Shell的小板键` 来执行sqlplus：

[oracle@localhost oracle_script]$ vi

#!/bin/bash

# user env
source ~/.bash_profile

VALUE=`sqlplus -S /nolog <<EOF

set heading off feedback off pagesize 0verify off echo off numwidth 4

conn scott/tiger

select count(*) from emp;

exit

EOF`

if [ "$VALUE" -gt 0 ]; then

echo "The number of rows is$VALUE."

exit 0

else

echo "There is no row in thetable."

注意：等号两边不能有空格，有空格会报错如下：

[oracle@localhost oracle_script]$ ./

./: line 2: VALUE: command notfound

./: line 8: [: : integer expressionexpected

There is no row in the table.

修改脚本权限

[oracle@localhost oracle_script]$ chmod +x

[oracle@localhost oracle_script]$ ll

总计 4

-rwxr-xr-x 1 oracle oinstall 154 01-1308:59

执行查看结果

[oracle@localhost oracle_script]$ ./

The number of rows is 14.

3、Sqlplus返回值给Shell(二)

该sqlplus使用 col 列名 new_value 变量名定义了变量并带参数exit, 将变量v_coun返回赋给了shell的$?

[oracle@localhost oracle_script]$

#!/bin/bash

# user env
source ~/.bash_profile

sqlplus -S /nolog > <<EOF

--set heading off feedback off pagesize 0verify off echo off numwidth 4

conn scott/tiger

col coun new_value v_coun

select count(*) coun from emp;

select * from emp where empno=7369;

exit v_coun

EOF

VALUE="$?"

echo "The number of rows is$VALUE."

备注：NEW_VALUE通常的使用方法为:

column column_name new_value var_name

new_value是将所获得的列值赋予到变量名，然后该变量名可以参与后续处理

修改脚本权限

[oracle@localhost oracle_script]$ chmod +x

[oracle@localhost oracle_script]$ ll

总计 16

-rw-r--r-- 1 oracle oinstall 5 01-16 15:10

-rwxr-xr-x 1 oracle oinstall 213 01-1310:00

-rwxr-xr-x 1 oracle oinstall 285 01-1615:08

-rwxr-xr-x 1 oracle oinstall 259 01-1615:10

执行查看结果

[oracle@localhost oracle_script]$ ./

The number of rows is 14.

4、shell传参给sqlplus

$1是传给SHELL的第一个参数,将参数传入给SQLPLUS , 变量赋值表达式的等号2边不能有空格.

[oracle@localhost oracle_script]$ vi

#!/bin/bash

# user env
source ~/.bash_profile

NAME="$1"

sqlplus -S scott/tiger <<EOF

select * from emp where ename =upper('$NAME');

exit

EOF

修改脚本权限

[oracle@localhost oracle_script]$ chmod +x

[oracle@localhost oracle_script]$ ll

总计 4

-rwxr-xr-x 1 oracle oinstall 154 01-1308:59

执行查看结果

[oracle@localhostoracle_script]$ ./

no rows selected

[oracle@localhost oracle_script]$ ./ smith

EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO -------- ---------- ------------------- --------- ---------- ---------- ----------

7369 SMITH CLERK 7902 17-DEC-80 800 20

5、安全Shell调用Sqlplus

为了保证连接数据库安全，每次调用脚本的时候要输入用户名和密码

[oracle@localhost oracle_script]$ vi

#!/bin/bash

# user env
source ~/.bash_profile

echo -n "Enter user name:"

read UNAME

echo -n "Enter password foruser:"

read PASSWD

sqlplus -S /nolog <<EOF

conn $UNAME/$PASSWD

select * from emp;

exit

EOF

[oracle@localhost oracle_script]$ ./

Enter user name:scott

Enter password for user:tiger

EMPNO ENAME JOB MGR HIREDATE SAL

---------- ---------- --------- ------------------- ---------- ----------

7369 SMITH CLERK 7902 17-DEC-80 800
