How to Grant truncate privilege to some tables of a different user in Oracle and same ..How we can do this in Oracle 11 g..Anyone please help on this
create a procedure that can truncate a table,
create or replace procedure do_truncate (tab_name in varchar2) as
begin
--For safety, only allow truncating a specific list of tables.
if tab_name in ('TEST1', 'TEST2', 'TEST3') then
execute immediate 'truncate table '||tab_name;
else
raise_application_error(-20000, 'The table '||tab_name||' is not allowed to be truncated.');
end if;
end;
/
grant execute on do_truncate to Dave;
Formal permission is "drop any table".
Dangerous though.

I wrote a Procedure which essentially used to drop table.
It works as expected , but the problem is As this Procedure is in "DW" schema and dropping table is in "SCRATCH".
Because of this, we get insufficient privileges.
Any way we can achieve this and solve the "privilege" issue?
CREATE OR REPLACE PROCEDURE DW.PROC AUTHID CURRENT_USER IS
V_TABLE_NAME VARCHAR2(255);
V_DELETE_DT NUMBER(33);
V_LIST SYS_REFCURSOR;
BEGIN
SELECT TO_NUMBER(VALUE) INTO V_DELETE_DT FROM DW.LIST_OF_TABLE
OPEN V_LIST FOR
SELECT OBJECT_NAME FROM ALL_OBJECTS WHERE OBJECT_TYPE= 'TABLE' AND
OBJECT_NAME LIKE '%DLY_BKP%' AND CREATED <=SYSDATE - V_DELETE_DT;
LOOP
FETCH V_LIST
INTO V_TABLE_NAME;
EXIT WHEN V_LIST%NOTFOUND;
EXECUTE IMMEDIATE 'DROP TABLE SCRATCH.'||V_TABLE_NAME ;
END LOOP;
CLOSE V_LIST;
END;
To drop a table in another schema, you must do one of the following:
Be granted the "DROP ANY TABLE" system privilege. This is highly elevated and it is likely your DBAs will balk at it, but it'll work.
Create a procedure owned by the table owner that accepts a table name as a parameter and issues the drop DDL on your behalf. Grant execute privs on the procedure to your connect user. This is usually the better choice. You can further enhance it to table-drive a list of tables or table name patterns that are white-listed or black-listed for drop, whatever makes sense.
At it's most simplest:
CREATE OR REPLACE PROCEDURE scratch.drop_table(in_table_name IN varchar2)
AS
BEGIN
EXECUTE IMMEDIATE 'DROP TABLE "'||in_table_name||'"';
END;
/
GRANT EXECUTE ON scratch.drop_table TO dw;
/
Then DW calls it:
BEGIN
scratch.drop_table('TABLE_TO_DROP');
END;
If for any reason you cannot create this procedure under the SCRATCH schema (which is an unreasonable restriction), you can create it under a privileged account like SYSTEM and also add the table owner name as an additional parameter. Then you most definitely will want to table-drive a set of white-listed owners to prevent misuse of the procedure.
I am having a stored procedure in user META. This SP truncates a table in user STAGE.
CREATE PROCEDURE META.sp_truncate_tablex
AUTHID CURRENT_USER
as
BEGIN
EXECUTE IMMEDIATE 'TRUNCATE TABLE STAGE.Tablex';
END;
When I run the SP I get RA-06598: insufficient INHERIT PRIVILEGES.
I have tried to make both users to DBA.
This means if I run SELECT grantee
WHERE granted_role = 'DBA'
ORDER BY grantee;
it shows me that META dn STAGE are DBA.
I have also tried: GRANT INHERIT PRIVILEGES ON USER STAGE TO META; But I still get the same error in Oracle 18.
Your problem is this clause:
AUTHID CURRENT_USER
This means the user who executes the procedure does so with their own privileges. So a user who is not META cannot run the procedure unless they have the DROP ANY TABLE privilege, in which case they don't need to run the procedure as they can truncate the table anyway.
The solution is to declare the procedure with
AUTHID DEFINER
Now the procedure executes with the privileges of its owner - META - who presumably owns the target table. Except they don't. The table is actually owned by STAGE. So STAGE needs to own the procedure as well.
As it happens, DEFINER rights are the default so we don't need to explicitly define them, except for clarity.
CREATE PROCEDURE STAGE.sp_truncate_tablex
AS
BEGIN
EXECUTE IMMEDIATE 'TRUNCATE TABLE STAGE.Tablex';
END;
I have a stored procedure for deleting partitions. Before starting, I have to delete a constraint.
I installed the stored procedure on system user. When I test the procedure I have this error: 'ORA-01031: insufficient privileges'.
This is a piece of code that I wrote:
BEGIN
EXECUTE IMMEDIATE 'ALTER TABLE USER_NAME.TABLE_NAME DISABLE CONSTRAINT CONSTRAINT_NAME';
EXCEPTION
WHEN OTHERS THEN
O_sCodError := 'NO_OK';
O_sDesError := 'Error at DISABLE CONSTRAINT_NAME: ' || SQLERRM || ';';
RETURN;
END;
Well, as I execute the stored procedure as system, I do not understand the reason for I have that error. And I think I eventually think the same error when I try to delete a partition.
Works for me on 11g XE:
SQL> show user
USER is "SCOTT"
SQL>
SQL> create table test
2 (id number constraint pk_test primary key,
3 name varchar2(20)
4 );
Table created.
SQL> connect system
Enter password:
Connected.
SQL> begin
2 execute immediate 'alter table scott.test disable constraint pk_test';
3 return;
4 end;
5 /
PL/SQL procedure successfully completed.

Please, follow that example and execute it in your database. Post the result (by editing the question, not as a comment).
First, you should never install custom code in an Oracle default schema like SYSTEM. Put your code in a dedicated application schema. Since it contains dynamic SQL (execute immediate) you might want to consider making it an "invoker's rights" procedure, then granting execute privileges on it to the user that will execute it.
That said, in Oracle 11g whoever's privileges are used to run the PL/SQL block must have direct permissions on the underlying table, not inherited permissions through a role like DBA. If the procedure has "definer's rights" then the schema that owns the procedure must have direct privileges on the table. If "invoker's rights" then the user executing the procedure must have the privileges.
See this link for additional details:
Execute immediate within Oracle Procedure
You must grant SYSTEM account direct privilege (not with a role) to run ALTER TABLE on the target table because roles are not enabled in stored procedures by default: https://asktom.oracle.com/Misc/RolesAndProcedures.html.
Try:
grant alter any table to system;
or
grant alter table on user_name.table_name to system;
I have written a procedure to grant permissions on all the tables of a particular schema to rest other schemas.
create or replace PROCEDURE GRANTS_PROC
IS
CURSOR GRANTS_CURSOR
IS
SELECT 'GRANT SELECT, INSERT, UPDATE, DELETE ON "'
||T.OWNER
||'"."'
||TABLE_NAME
||'" TO '
||(SELECT rtrim(listagg(U.username||',')
within group (order by U.username),',') USERNAME
FROM ALL_USERS U
WHERE U.USERNAME!=T.OWNER
AND U.USERNAME IN
('AAA','BBB','CCC','DDD','EEE','FFF','GGG','HHH','III'))||';' FINAL_TXT
FROM ALL_TABLES T
WHERE T.OWNER IN
('AAA','BBB','CCC','DDD','EEE','FFF','GGG','HHH','III')
ORDER BY T.OWNER,UPPER(T.TABLE_NAME);
BEGIN
--DBMS_OUTPUT.PUT_LINE('CURSOR_GRANTS.FINAL_TXT');
--QRY_TEXT:='ABC';
FOR CURSOR_GRANTS IN GRANTS_CURSOR
LOOP
DBMS_OUTPUT.PUT_LINE(CURSOR_GRANTS.FINAL_TXT);
EXECUTE IMMEDIATE CURSOR_GRANTS.FINAL_TXT;
END LOOP;
END;
/
The above procedure compiled successfully, but while execution it is not getting into FOR loop to run the EXECUTE IMMEDIATE block but PL/SQL procedure compiled successfully.
What could be done to fix my procedure and make it work?
All_USERS and ALL_TABLES should be changed to DBA_USERS and DBA_TABLES, Hence my procedure works.
Because the all_tables view shows the tables that the owner of the stored procedure has privileges on, so, unless the stored procedure is being created by a privileged user, or a user that already has those grants (with grant option so they can actually give the privileges), there may be nothing in all_tables that qualifies.
I need to do truncate table and then insert data in that table using procedure.
However, one does like dinamic sql but the other one doesn't:
create or replace
procedure RECREATE_AGGREGATE
AUTHID DEFINER
AS
BEGIN
TRUNCATE TABLE AGGREGATE;
INSERT INTO AGGREGATE SELECT * FROM OLD_AGGREGATE;
END;
Error(6,14): PLS-00103: Encountered the symbol "TABLE" when expecting one of the following: := . ( # % ; The symbol ":= was inserted before "TABLE" to continue.
If I add execute immediate around TRUNCATE statement, it works fine, but insert is erroring out.
If I remove it, TRUNCATE TABLE complains...
create or replace
procedure RECREATE_AGGREGATE
AUTHID DEFINER
AS
BEGIN
execute immediate 'TRUNCATE TABLE AGGREGATE';
INSERT INTO AGGREGATE SELECT * FROM OLD_AGGREGATE;
END;
Error(7,5): PL/SQL: SQL Statement ignored
Error(7,84): PL/SQL: ORA-00942: table or view does not exist
Can some shed some light here?
create or replace
procedure RECREATE_AGGREGATE
AUTHID DEFINER
AS
BEGIN
EXECUTE IMMEDIATE 'TRUNCATE TABLE AGGREGATE';
INSERT INTO AGGREGATE SELECT * FROM OLD_AGGREGATE;
END;
will work assuming that you have appropriate privileges.
Based on your edit (and echoing #OracleUser's comment), you're likely getting an error running your INSERT statement because old_aggregate is owned by another user and you only have SELECT privileges on that table via a role. If you want to do something in a definer's rights stored procedure, you'll need to have those privileges granted directly to you (or be using 12c which lets you grant privileges to blocks of code rather than to users).
Assuming you want to use a definer's rights stored procedure, you'd need the owner of old_aggregate (or the DBA) to
GRANT SELECT
ON old_user.old_aggregate
TO new_user;
You can verify that you only have the privilege via a role by disabling roles for the session. I'll wager that if you do
SQL> set role none;
SQL> SELECT * FROM old_aggregate
that you'll get an ORA-00942 error as well. This is a good way of simulating what privileges will be available to the user inside a definer's rights stored procedure.
"TRUNCATE is DDL (data definition language). You cannot perform DDL from within PL/SQL. "
