Linux Unix shell 调用 PL/SQL

Linux/Unix 下除了调用SQL之外，调用PL/SQL也是DBA经常碰到的情形，下面主要通过一些示例给出如何在shell下面来调用pl/sql。

1、将pl/sql代码逐行输入到临时文件

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

if test $# -lt 1
then
echo You must pass a SID
exit
fi

ORACLE_SID=$1; export ORACLE_SID

echo “set serveroutput on size 1000000” > /tmp/plsql_scr.sql

echo “declare” >> /tmp/plsql_scr.sql
echo “cursor c1 (param1 varchar2) is” >> /tmp/plsql_scr.sql
echo “select decode(substr(value, 1, 1), ‘?’, param1 || substr(value, 2), value) dd” >> /tmp/plsql_scr.sql
echo “from v\$parameter where name = ‘background_dump_dest’;” >> /tmp/plsql_scr.sql
echo “v_value v\$parameter.value%type;” >> /tmp/plsql_scr.sql
echo “begin open c1 (‘$ORACLE_HOME’); fetch c1 into v_value; close c1;” >> /tmp/plsql_scr.sql
echo “dbms_output.put_line(v_value);” >> /tmp/plsql_scr.sql
echo “end;” >> /tmp/plsql_scr.sql

if [ -s /tmp/plsql_scr.sql ]; then
echo -e “Running SQL script to find out bdump directory… \n”
$ORACLE_HOME/bin/sqlplus -s “/ as sysdba” > /tmp/plsql_scr_result.log << EOF
@/tmp/plsql_scr.sql
EOF
fi

echo ” Check the reslut “
echo “————————“
cat /tmp/plsql_scr_result.log

exit

#上面的代码是查询指定Oracle SID 的dump路径。
#通过逐行逐行的方式将代码添加到文件以形成pl/sql代码。
#需要注意转义字符的使用,对于parameter 的$符号，我们进行了转义。

2、一次性输入pl/sql代码到临时文件
robin@SZDB:~/dba_scripts/custom/bin> more shell_call_plsql_2.sh
#/bin/bash

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

if test $# -lt 1
then
echo You must pass a SID
exit
fi

ORACLE_SID=$1; export ORACLE_SID

echo “

select decode(substr(value, 1, 1),’?’ , param1 || substr(value, 2), value) dd
from v\$parameter where name = ‘background_dump_dest’;

end;

exit “>/tmp/plsql_scr.sql
