一、最簡單的shell里調(diào)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執(zhí)行結(jié)果傳遞給shell方法一

注意sqlplus段使用老板鍵`了, 賦變量的等號兩側(cè)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執(zhí)行結(jié)果傳遞給shell方法二

注意sqlplus段使用 col .. new_value .. 定義了變量并帶參數(shù)exit, 然后自動賦給了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程序參數(shù)傳遞給sqlplus

$1表示第一個參數(shù), sqlplus里可以直接使用, 賦變量的等號兩側(cè)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、為了安全要求每次執(zhí)行shell都手工輸入密碼

$ 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、為了安全從文件讀取密碼

對密碼文件設(shè)置權(quán)限, 只有用戶自己才能讀寫.

$ 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
