Not able to return value for pl/sql to shell

Question

Hi,
I'm calling pl/sql script from my shell script. Have set a flag in the pl/sql. Trying to return the value of the flag back to the shell script, but it is not working. My shell is ksh
Please help....
SHELL code trysnir.sh file--->
<code>
#!/bin/ksh
flaga=50
echo $flaga
flaga=`sqlplus -S user/pass@sid@/opt/local/sql/update.sql > LOGFILE`
echo aftersql
echo $flaga
if [ $flaga -lt 50 ]; then
error "Previous Load failed"
exit 3
fi
echo complete
</code>
SQL CODE file for update.sql--->
<code>
variable flaga number
declare
sessin_id number;
begin
Select Load_Sessin('aaa','xx') into sessin_id from dual;
if sessin_id is NULL then
:flaga :=10;
end if;
dbms_output.put_line(flaga);
end;
exit :flaga
</code>
But this returns me --->
+50+
aftersql
PL/SQL procedure successfully completed.
tyrnir.sh[9]: procedure: unknown test operator
complete
Please advise.... I have been trying since past 3 hrs and tried all search and everything i could but in vain.
Many Thanks....

Answer 1

executing this way will return you the last output from the sqlplus command. I think suppressing message PL/SQL procedure successfully completed. and putting a DBMS_OUTPUT.PUT_LINE(vflag) (this you have done already) will give you the desired result. So in update.sql put some extra line as below:
set feedback off
set serveroutput on
<your code goes here>
