Retrieving the values from a Table ????
I am facing a problem on selecting the values from the Table...
Table Creation:
-------------------
Create table product(bat_in_dir varchar2(50),bat_out_dir varchar2(50));
In the above two columns i am having 9 directories names & paths in each column..
But i need to pass the output like below after getting the directory names from the table.Here the directory paths & names are not constant.
For bat_in_dir:
-----------------------------
BAC_in1=/home/test/
BAC_in2=/test/
.
.
.
.
BAC_in3=/product/
For bat_out_dir:
-----------------------------
BAC_out1=/home/test/
BAC_out2=/test/
.
.
.
.
BAC_out9=/product/
----------------------------------
I used this below code to get the Output from the Table in HP-Unix platform...
Example Shell Script:
-----------------------------------------------
v_filedate=`echo " select to_char(add_months(sysdate, -9),'MONYYYY') from dual; " |
$ORACLE_HOME/bin/sqlplus -s USERNAME/PASSWORD|tail -2 | head -1`;
echo $v_filedate;
-----------------------------------------------
Can any body help me???
Thanks & Regards

Re: Retrieving the values from a Table ????
1. How are you telling sqlplus which database to query?
2. What does
$ORACLE_HOME/bin/sqlplus -s USERNAME/PASSWORD << EOF
>select to_char(add_months(sysdate,-9),'MONYYYY') from dual
>EOF
yield?
3. What is the relationship between the tables 'product' and 'dual'?

Re: Retrieving the values from a Table ????
---test.sql---
select to_char(add_months(sysdate, -9),'MONYYYY') from dual;
exit
-----end-----
---test.sh---
PATH=$ORACLE_HOME/bin:$PATH
v_filedate=$(sqlplus -S USERNAME/PASSWORD @test.sql|tail -2|head -1)
echo $v_filedate;
-----end-----
Hope this helps.

Re: Retrieving the values from a Table ????
The query which i have given its just an example only..
The actual query looks like this...
----------------------------
v_filedate=`echo " select bat_in_dir,bat_out_dir from product; " |
$ORACLE_HOME/bin/sqlplus -s USERNAME/PASSWORD|tail -2 | head -1`;
echo $v_filedate;
-----------------------------
The above mentioned query may not be correct...
The above script was executing successfully with out giving any rows..I want that two column output in to different varaibles as described above..
My purpose is to delete some files depending upon the directories..The directories are not constant and we dont know which direcories they were.Thats the reason i have to select the directory paths from the table and delete the files stored in those directories in the OS...
Can any one help me??
Thanks & Regards

Re: Retrieving the values from a Table ????
don't forget to put an "exit;" in the SQL-script.
good luck,
Thierry.

Re: Retrieving the values from a Table ????
maybe a different approach is possible: creation of a delete script from within sqlplus:
--- my.sql --
set heading off
set feedback off
spool /tmp/mydelete.sh
select 'find ' || bac_in_dir || ' ' || bac_out_dir || ' -type f -mtime +270 -exec rm {} \;'
from dual;
spool off;
exit;
-- end my.sql ---
-- start script
sqlplus -s u/p @my.sql
sh /tmp/mydelete.sh
-- end script
that's it, the sql should generate something like:
find /home/test/ /home/test/ -type f -mtime +270 -exec rm {} \;
(if 'BAC_in1=' is included in the value, you will need to trim it)
regards,
Thierry.
