If I m not wrong, you are trying to execute same query for 25 column ids on a customer table at a single time.

For that your following qeury will list out column ids in abc.txt file. Correct?

Code:
sqlplus -s $ORA_CONN <<EOF
SET SERVEROUTPUT ON
SET FEED OFF
spool abc.txt
BEGIN
   FOR i IN (SELECT ID FROM customer)
   LOOP
      DBMS_OUTPUT.put_line ( 'value ' || i.ID);
   END LOOP;
END;
/
spool off
EOF

abc.txt will look like
Quote:
1
2
3
4
5
..
..
25
Now to execute same query as follows on all listed column ids, you can write a script like


Code:
#!/bin/ksh

    # First list out Column ids in abc.txt file
sqlplus -s $ORA_CONN <<EOF
SET SERVEROUTPUT ON
SET FEED OFF
spool abc.txt
BEGIN
   FOR i IN (SELECT ID FROM customer)
   LOOP
      DBMS_OUTPUT.put_line ( 'value ' || i.ID);
   END LOOP;
END;
/
spool off
EOF

    # Now for each data in abc.txt, execute second query in background
for myID in `cat abc.txt | xargs`
do
sqlplus -s $ORA_CONN <<EOF!
        SPOOL ${rep_name}report_${rep_part}_${sysdate1}.txt;
        SELECT * FROM customer WHERE col1="$myID"
           AND (  col2='sumthing')
        UNION
        SELECT * FROM customer WHERE col1="$myID"
        AND (condition);
        Spool off;
exit
EOF! &
done

glgenqueries

GLGENQUERIES(3G)						    OpenGL 3.3							  GLGENQUERIES(3G)

NAME

       glGenQueries - generate query object names

C SPECIFICATION

       void glGenQueries(GLsizei n, GLuint * ids);

PARAMETERS

       n
	   Specifies the number of query object names to be generated.

       ids
	   Specifies an array in which the generated query object names are stored.

DESCRIPTION

       glGenQueries returns n query object names in ids. There is no guarantee that the names form a contiguous set of integers; however, it is
       guaranteed that none of the returned names was in use immediately before the call to glGenQueries.

       Query object names returned by a call to glGenQueries are not returned by subsequent calls, unless they are first deleted with
       glDeleteQueries().

       No query objects are associated with the returned query object names until they are first used by calling glBeginQuery().

ERRORS

       GL_INVALID_VALUE is generated if n is negative.

       GL_INVALID_OPERATION is generated if glGenQueries is executed between the execution of glBeginQuery() and the corresponding execution of
       glEndQuery().

ASSOCIATED GETS

       glIsQuery()

SEE ALSO

       glBeginQuery(), glDeleteQueries(), glEndQuery()
