आप अपनी स्क्रिप्ट में डायनामिक क्वेरी बना सकते हैं, इस उदाहरण को देखें:
variable rr refcursor
declare
bb varchar2(4000);
cc varchar2( 30000 );
begin
WITH PIVOT_DATA AS (
SELECT *
FROM
(
SELECT USERNAME, GRANTED_ROLE
FROM DBA_USERS U LEFT OUTER JOIN DBA_ROLE_PRIVS R
ON U.USERNAME = R.GRANTEE
)
)
select ''''|| listagg( granted_role, ''',''' )
within group( order by granted_role ) || '''' as x
into bb
from (
select distinct granted_role from pivot_data
)
;
cc := q'[
WITH PIVOT_DATA AS (
SELECT *
FROM
(
SELECT USERNAME, GRANTED_ROLE
FROM DBA_USERS U LEFT OUTER JOIN DBA_ROLE_PRIVS R
ON U.USERNAME = R.GRANTEE
)
)
SELECT *
FROM PIVOT_DATA
PIVOT
(
COUNT(GRANTED_ROLE)
FOR GRANTED_ROLE
IN(]' || bb || q'[) -- Just an example
)
ORDER BY USERNAME ASC]';
open :rr for cc;
end;
/
SET PAGESIZE 200
SET LINESIZE 16000
print :rr
यहाँ परिणाम है (केवल छोटा टुकड़ा, क्योंकि यह बहुत चौड़ा और लंबा है)
