Hi all,

My procedure below is failing to provide the desired result and I've
failed to track down what is the cause. The procedure is supposed to
dynamically grant roll on objects to users. I've tested the cursor SQL
and it's working fine. However, sql_stmt is failing. When I run the
procedure I get the following error:

Warning: Procedure created with compilation errors.

SQL> sho err

Any help will be appreciated.

Create or Replace Procedure g_r(grant_revoke_p varchar2,
                                objects_p varchar2,
                                instn_p varchar2,
                                object_p varchar2,
                                Debug NUMBER DEFAULT 0) Is

sql_stmt varchar2(20000);
grant_revoke  VARCHAR2(30);
objects   VARCHAR2(30);
instn  VARCHAR2(30);
object  VARCHAR2(30);

Cursor c_gr2 Is
        select decode(upper('G'),'G','GRANT','R','REVOKE','***UNKNOWN
OPTION***')||' '||VIEW_NAME,
               decode(upper('G'),'G','TO'   ,'R','FROM'  ,'***UNKNOWN
OPTION***')||' '||
               USERNAME
          from USER_VIEWS, ALL_USERS
         where USERNAME like 'USER_L_%'
           and substr(USERNAME,-3) like translate('%','*','%')
           and upper('G') in ('G')
           and upper('A')     in ('A')
           and VIEW_NAME like upper('%')
                 order by 1;
r_gr2 c_gr2%rowtype;

Begin
grant_revoke := UPPER(grant_revoke_p);
objects := UPPER(objects_p);
instn := UPPER(instn_p);
object := UPPER(object_p);

Open c_gr2;
  Loop
  Fetch c_gr2 INTO r_gr2;
  sql_stmt := grant_revoke||' SELECT ON '||r_gr2.VIEW_NAME||
grant_revoke||r_gr2.USERNAME;

       DBMS_OUTPUT.Put_Line(sql_stmt);

    EXIT WHEN c_gr2%NOTFOUND;

You need to alias the column names in your cursor. r_gr does not have
columns named VIEW_NAME or USERNAME. The columns are
"decode(upper('G'),'G','GRANT','R','REVOKE','***UNKNOWN OPTION***')||'
'||VIEW_NAME" and
"decode(upper('G'),'G','TO'   ,'R','FROM'  ,'***UNKNOWN OPTION***')||'
'|| USERNAME- Hide quoted text -

Thanks Ken!

I created the aliases for the two DB columns as you suggested, thus:

select
decode(upper(grant_revoke),'G','GRANT','R','REVOKE','***UKJENT_OPSJON***')|­|'
'||VIEW_NAME as VIEW_NAME,
decode(upper(grant_revoke),'G','TO'   ,'R','FROM'  ,'***UKJENT_OPSJON***')||'
'||USERNAME as USERNAME

The procedure is compilling but something else is happening. When I
execute it. In SQL*PLUS, I get:
SQL> exec g_r('G','A','%','%',1)
R SELECT ON R

In Toad, when I execute the procedure in the Schema Browser, I get the
same result as in SQL*PLUS. When I execute it as a script (in Toad), I
get close to my desired result, i.e;

GRANT SELECT ON GRADES TO SUP_218;
GRANT SELECT ON GRADES TO SUP_219;
GRANT SELECT ON GRADES TO SUP_221;
...
...
...

However, when I change the parameter value for grant_revoke to 'R' so
that it prints REVOKE and FROM respectively, I still get the same
result as above. Any suggestion/s to what I can do to solve thing
problem?

Thanks in advance.
