Hi friends,

I have written a script which retrieves one value from the database.
It takes time for the sql query to get the desired output. So the query runs fine from TOAD or from UNIX console.

However if I put this in a script it doesn't work. The script is as below.

#! /bin/ksh
DB_VALID_CDR=`sqlplus -s username/password<<!EOF | grep -v "^Connected" 2>&1
set termout off echo off feedback off pause off timing off time off
set pages 0
clear breaks
clear compute
set termout on
select a.VALUE_INTEGER from client_statistics a, statistic_type b where a.STATISTICS_TYPE=b.Statistic_type_id and a.STATISTICS_OBJECT like '%20071217102445_9673324_AG40_20071217101738_0000002118%' and b.STATISTIC_TYPE='valid_cdrs'
EXIT
!EOF`
echo $DB_VALID_CDR

I strongly believe that the issue is with the query taking time to return the value.

Please let me know how to tackle the issue.

Many thanks

Hi Michel,

Sorry for that, please consider this as a mistake from a naive user to this forum.

#! /bin/ksh
DB_VALID_CDR=`sqlplus -s username/password<<!EOF | grep -v "^Connected" 2>&1
set termout off echo off feedback off pause off timing off time off
set pages 0
clear breaks
clear compute
set termout on
select a.VALUE_INTEGER 
from client_statistics a, statistic_type b 
where a.STATISTICS_TYPE=b.Statistic_type_id 
and a.STATISTICS_OBJECT like '%20071217102445_9673324_AG40_20071217101738_0000002118%' 
and b.STATISTIC_TYPE='valid_cdrs'
EXIT
!EOF`
echo "valid cdrs is: "$DB_VALID_CDR


I tried redirecting the output to a log, and it says

valid cdrs is:
logout

What about "Make sure that lines of code do not exceed 80 characters when you format. Use the "Preview Message" button."?
Can you do this next time?

Execute the sqlplus part without the grep and redirection and post the result.

Michel

dvivekd, I can understand your posting just fine without any fancy formatting. Try removing "termount off" from your code.
set echo on
select sysdate from dual;
set termout off
select sysdate from dual;

Connected to:
Oracle9i Enterprise Edition Release 9.2.0.8.0 - 64bit Production
With the Partitioning option
JServer Release 9.2.0.8.0 - Production

SQL> select sysdate from dual;

SYSDATE
---------
17-DEC-07

SQL> set termout off
SQL>
