a) change test.sql to
1.  spool the output to a file
2.  ad a unique marker to line with counter

b) modify your script to extract the value

ad a)
set serveroutput on size 200000
set linesize 200
set feedback on
spool yourdirectory/testoutput.lst
declare
v_exception date;
cnt integer;
begin
select Case When To_Number(To_Char(Sysdate,'HH24')) >= 19
  Then (select trunc(sysdate+1) from dual) Else trunc(sysdate) End into v_exception from dual;
    select count(*)into cnt from Cust where E_DATE=to_date(v_exception-15);
    dbms_output.put_line('counter: ' || cnt);
end;
/
spool off


ad b)
i don't kwow bash script
but in korn shell it would look  like

sqlplus xx/xx@DNYNTK01 @test.sql
CNT=`grep counter yourdirectory/testoutput.lst | cut -d' ' c2`
# select the line containing counter from output list
# split the selected line in columns separated by a space
# take second columns of the line
# assign the value to CNT

Or you could try this:


#!/bin/bash
#
CNT=`sqlplus -s xx/xx@DNYNTK01 @test.sql` 
### And change your test.sql script to this:
SET lin 200 pages 0 feed off echo off ver off term off
SELECT COUNT (*)
  FROM cust
 WHERE e_date =
            (CASE
                WHEN TO_NUMBER (TO_CHAR (SYSDATE, 'HH24')) >= 19
                   THEN TRUNC (SYSDATE + 1)
                ELSE TRUNC (SYSDATE)
             END
            )
          - 15
/
exit

Give this a try. It's basically the same as the scripts in you other threads with a minor tweak:

#!/usr/bin/bash
var=$(sqlplus -s user/password@db @test)
echo "I got: " $var

In you .sql file, you're missing the end 'exit' and you need to set feedback off not on.


MikeOM_DBA,

I'm not sure what the final goal is here. This is the 3rd variation of pretty much the same question.

cnt integer; 
begin

end;

exit;
