从linux连接oracle时在oracle alter命令中连接输入变量

Question

我正在尝试使用以下代码在 oracle 表空间中添加数据文件，但出现错误：ORA-02140：无效的表空间名 请参考 output3 创建数据文件：

for i in `echo $output1 | tr ' ' '\n' | tr '\n' ' '`;
do
echo $i;    **#Its printing tablespace name like SYSTEM**
output2=`sqlplus -s usr/pwd as sysbackup <<END2
set serveroutput on;
set linesize 200
set head off;
SELECT TABLESPACE_NAME ||','|| ROUND (SUM (BYTES) / 1048576) FROM DBA_DATA_FILES WHERE TABLESPACE_NAME = '${i}' GROUP BY TABLESPACE_NAME;
exit;
END2`

**#output2 is printing tablespace name and total tablespace size like SYSAUX 2048**

echo $output2 | tr ' ' '\n' > test.csv


while IFS=',' read -r col1 col2
do
echo $col2
fiftin_per=$((col2/15))
echo $fiftin_per  **#Feteched column2 from csv file which contains total tablespace space and calculated 15 per of it**
if [[ "${fiftin_per}" -gt "${avail_space}" ]];
then
echo "Assign to manual queue as required space is not available on mount point."
else
var='/'
dfname=".data00"
random_val=`shuf -i 100000000-1000000000 -n 1`
ext=".dbf"
fname="'$mount_name$var${i}$random_val$ext'"
echo $fname  **#printing datafilename like \oradata\fname\.dbf**
echo ${i}
output3=`sqlplus -s usr/pwd as sysbackup <<END2
set serveroutput on;
set linesize 200
set head off;
DECLARE
var varchar(50);
BEGIN
dbms_output.put_line("Value of i"||${i});
END;
/
exit;
END2`
echo $output3  **#Trying to add datafile but getting error ORA-02140**
fi
done < test.csv
done

我得到低于输出，我无法在选择命令中传递 linux 变量。请参考 output2 相同。但是，当我尝试从 linux for 循环传递相同的变量以更改命令或 dbms_output.put_line 时出现错误：PLS-00357: Table,View Or Sequence reference 'SYSAUX' not allowed in this context ORA-06550: line 4, column 1 : PL/SQL: 语句被忽略

Output : 
/oradata01/POCDB/data/system01.dbf
/oradata01/POCDB/data
208958
SYSAUX TEST5
SYSAUX
2048
136
' /oradata01/POCDB/data/SYSAUX465368588.dbf'
dbms_output.put_line('Value of i'||SYSAUX); 

 PLS-00357: Table,View Or Sequence reference 'SYSAUX' not allowed in this context ORA-06550: line 4, column 1: PL/SQL: Statement ignored

Answer 1

我已将变量声明如下：

output3=`sqlplus -s usr/pwd as sysbackup <<END2
set serveroutput on;
set linesize 200
set head off;
DECLARE
var varchar(50):='${i}';
BEGIN
dbms_output.put_line("Value of i"||var);
END;
/
exit;
END2`

output : Its printing the tablespace name which I am getting from linux loop
