Grant truncate HR. EMP to SCOTT

Hi all

11.2.0.1

What specific privilege can grant truncate table to a user?

I'm confused:

Connect as SYS:

SQL > grant all on human resources. EMP to SCOTT;

Grant succeeded.

Connect as SCOTT:

SQL > truncate table HR. EMP;

Table truncated.

Connect as SYS:

SQL > revoke all on human resources. SCOTT EMP;

Revoke succeeded.


Connect as SCOTT:

SQL > truncate table HR. EMP;

Table truncated.


Why SCOTT might still truncate the table?


Thank you



I'm going to assume that these are not temporary tables in fact (that is, they are not global temporary tables)

CREATE PROCEDURE table_owner.truncate_table( p_table_name in varchar2 )

AS
BEGIN
IF( p_table_name IN (<>))
THEN
   EXECUTE IMMEDIATE 'TRUNCATE TABLE ' || p_table_name;
END IF;
END;

Of course, you can add additional logging logic, or you can allow different users to truncate different tables...

    Where's the harm? Thank you

    1. you created a synonym private sys_dba. You must create to test.
    2. connect with the current_schema return to test test changes. Change it if after you login as test.

    So, either:

    connection test
    create synonym emp for scott.emp;
    Select * from emp;

    or:

    connect [any user who created public synonym privileges]
    create public synonym emp for scott.emp;
    connection test
    Select * from emp;

    or:

    connection test
    ALTER session set current_schema = SCOTT;
    Select * from emp;

  • Import/export DataPump object grants given by another user

    Hello

    I searched through the forum and the documentation but couldn't find an answer. I have the following case:

    (1) I have a USER1 user who did not receive subsidies on the tables belonging to the user SCOTT.
    (2) user SCOTT gives the right to SELECT for his table EMP user1:
    Grant select on emp for User1;

    (3) I do exporting of the User1 schema (schema = User1). But in addition I also perform a full database export (full = y)
    (4) I have let down the user User1 and then import back

    After importation, the USER1 user has the right to SELECT on SCOTT. EMP more (no matter if I imported the schema of the schema or full dump of export file mode). Is it possible to import the user so that it has the same exact privileges that he had for the export (also the ones he was given to her by other users)? I know that the privileges granted to objects owned by SYS are not exported, but what about other non-system users?

    Thanks in advance for any answers.

    Kind regards
    Swear

    Swear,

    Subsidies are impoted when the objects to which they belong are imported, not when the schema that the grants were awarded to the is imported. So, given that scott made the concession on scott.emp to user1, this grant be imported when scott.emp is imported. They get also only exported when the object is exported. Because scott.emp was not exported, this grant will not be exported when only User1 schema is exported.

    I don't know an import of the single step that you will get what you want. If it's just the grants that you are looking for, you could make, it is 2 steps and should be an export complete dumpfile. Export could be reduced down a bit so it would be a condensed dumpfile. Here's what you do:

    1. from the source database:
    a. do this if you want a digest dumpfile
    Directory System/Manager expdp dumpfile = full_grant.dmp dpump_dir = include = grant
    b. do that if you want a complete dumpfile
    expdp System/Manager directory = dpump_dir dumpfile = full.dmp

    2 from the source or the target database:
    a. If you have just the source grants follow these steps:
    Directory System/Manager Impdp = dpump_dir dumpfile = full_grant.dmp sqlfile = grant_only.sql
    b. If you don't have a full dump and only want to see grants, so that
    Directory System/Manager Impdp dumpfile = full.dmp dpump_dir = include = grant sqlfile = grant_only.sql
    c. If you hav only a complete dumpfile and you want to see everything then
    Directory System/Manager Impdp = dpump_dir dumpfile = full.dmp sqlfile = full.sql

    Now, you can edit one of these files, .sql to find the commands you want. Your best bet would be to look at grant_only.sql and search for "to user1. This will give you all the subsidies granted to User1. These could be run from sqlplus.

    A shortcut if you have configured database links would be something like:
    Directory System/Manager Impdp = network_link dpump_dir = link_from_target_to_source include grant sqlfile = grant_only.sql =
    Then, edit the file as shown above.

    I hope this helps.

  • Granting of privileges through role does not not for PL/SQL

    Version: 11.2.0.2


    In our shop, we don't grant privileges directly to a user, give us it to a role, and grant this role to user scheduled grantee.

    Granting of privileges through a role seems to be fine with the SQL engine. But it does not PL/SQL engine.

    In the example below, the GLS_DEV user is granted access SELECT on SCOTT.pets table through a role called tstrole. GLS_DEV can select the SQL table. But does not seem to PL/SQL engine to find out.

    Reproduce the problem:
    SQL> show user
USER is "SCOTT"

SQL> select * from pets;

NAME
-----------------------------------
PLUTO


SQL> conn / as sysdba
Connected.


SQL> create user GLS_DEV identified by test1234 default tablespace TSTDATA;

User created.

SQL> alter user GLS_DEV quota 25m on TSTDATA;

User altered.


SQL> grant create session, resource to GLS_DEV;

Grant succeeded.


--- Granting SELECT privilege on scott.pets to tstrole and then grant this role to GLS_DEV.

SQL> conn / as sysdba
Connected.
SQL>
SQL> create role tstrole;

Role created.

SQL> grant select on scott.pets to tstrole;

Grant succeeded.

SQL> grant tstrole to GLS_DEV;

Grant succeeded.

SQL> conn GLS_DEV/test1234
Connected.
SQL>
SQL> select * From scott.pets;

NAME
-----------------------------------
PLUTO

---- All fine till here. From SQL engine , GLS_DEV user can SELECT scott.pets table.

--- Now , I am going to create a PL/SQL object in GLS_DEV which tries to refer scott.pets

SQL> show user
USER is "GLS_DEV"


create or replace procedure my_proc
is
myvariable varchar2(35);

begin
     select name into myvariable from scott.pets ;

     dbms_output.put_line(myvariable);

end my_proc;

--- PL/SQL Engine doesn't seem to know that GLS_DEV has select privilege on scott.pets indirectly granted through a role

    Has anyone encountered the same problem?

    Ok. Thank you all.
    There is no work around for this like using the clause AUTHID or something?

    Yes. using AUTHID (Summoner vs rights define) can make a difference.
    However it makes sense that pl/sql uses roles a little differently. Although at first glance, it is hard to see why. The reasoning is similar to the difference between a user and a schema.

    A user is a person who connects to a database. It has a role and this role defines what privileges he gets when you work with data.
    A schema consists of several objects that reside in the database. A package is also such an object. This package is valid, it is necessary to have all privileges directly. A role can be enabled and is a sort of temporary right. A direct subsidy has a permanent status. A user will only get the right to run this package/procedure/function. The package is a type of user interface. It encapsulates the privileges necessary to do something about this user.

    The logical problem happens only when the user and packaging are in the same scheme. The best approach is to have the package in the normal pattern and have a separate "schema access" with which the user connects. Give then execute privs on the package for this second scheme.

  • Syntax of GRANT: grant SELECT on table privileges to a user on a remote database

    Hello
    I have two databases: DEV1 and DEV2. Dev1 is my source database and DEV2 is the target database. There is a table in the diagram A on Dev1. I created a DBLINK PUBLIC 'TESTDBLINK' in the diagram B on DEV2 that connects to figure A on DEV1.

    Machine of Table for the database schema
    DEV1 AN EMP 192.168.210.10

    Database Machine Lik database schema
    DEV2 B TESTDBLINK 192.168.210.11

    How to SELECT on the schema Table EMP (DEV1) diagram b the DEV2 privileges? What is the syntax?


    Sign up for example in the form of scheme A on DEV 1

    SQL > GRANT SELECT ON EMP to? * *

    Thanks for your contributions
    Harry

    Do not give this table in diagram A diagram B.

    Inside the diagram B, you can just issue a select statement as follows:

    select *
from table@db-link-to-A

    Oracle connects to the remote instance by using the credentials of the scheme A, and since A is the owner of this table, Oracle can already access the table.

    To create a primary key or foreign in the object on the other, what a privilege devrais I need?

    Thank you

    To create a primary key or foreign in the object on the other, what a privilege devrais I need?

    This is generally NOT a good idea.

    Why do you need a primary key in a different schema from the owner of the table. If you do this, you will ALWAYS have a dependency between these two patterns.

    You must be able to alter the table and create indexes of the other schema...

    For the ALTER statement:

    http://docs.Oracle.com/CD/B28359_01/server.111/b28286/statements_3001.htm

    Prerequisites

    The table must be in your own schema or you must have ALTER privileges of objects on the table, or you must have ALTER ANY TABLE system privilege.

    For indexes

    http://docs.Oracle.com/CD/B28359_01/server.111/b28286/statements_5011.htm#i2062403

    Prerequisites

    To create an index in your own schema, one of the following conditions must be true:

    • The table or cluster be indexed must be in your own schema.
    • You must have the INDEX object privilege on the table to be indexed.
    • You must have the CREATE ANY INDEX system privilege.

    To create an index in another schema, you must have the CREATE ANY INDEX system privilege. In addition, the owner of the schema to contain the index must have either the UNLIMITED TABLESPACE quota privilege or space of the system on the storage space to store the index or index partitions.

    TIA...

    Personally, I wouldn't bother with a task of setting.

    If you are lucky who will recommend a sql profile based on adjustments of cardinality which may or may not be effective.

    I would just use either the COE_XFR_SQL_PROFILE. SQL script SQLT ( doc-id 1487302.1Support) or use SQL Plan baseline to apply the previous execution plan. The latter has the advantage of being able to make an evolution controlled all plans potentially better which would otherwise be generated.

    You can choose the older, better plan AWR in the same database or a different database, and then transport it.

    Please guide me how to avoid this error and also how to print cell wise why because it's printed in a single cell.

    Please answer...

    What is a network drive? If so, try if the same code is running on a local directory, maybe the network drive is smehow is not accessible.

    Hello
    I use this query to find the LIST OF THE LOCKED OBJECT

    SELECT a.type,
    Owner of substr (a.Owner, 1, 30),
    a.SID,
    Subject substr (a.Object, 1, 30)
    ACCESS $ v one
    WHERE a.owner NOT IN ('SYS', 'PUBLIC')
    ORDER BY 1,2,3,4

    It showing record 9475 is this straight becauze some slow EEG database time.

    I have another problem in a different database that generates a lot of trc file, in the file dir udump

    Thank you
    MAAN

    Hello

    Documentation says Oracle

    «v$ ACCESS displays information about locks that are currently taxed on the library cache objects.» The locks are imposed to ensure that they are not aged in the cache of the library so that they are required for the execution of SQL".

    It is only provides information session at which are currently access what are the objects of the library cache. If you check 25 SID and SId 24 both are perhaps to access the information, which is the trainer /waiter that we do not know. Now, if you check the v$ locked_object you can get the details.

    If you check the base tables - it recovers since "x$ ktcxb"-information of transactions of the v kernel $ locked_object
    When in access of $ v it retrieves information from x$ kglob and x$ kgldp - its generic kernel - object they access dependencies - architecture/logical point of view.

    There will be cases occurs when locking contention access $ v is questioned through - because high latch activity goes on access tables x $.

    Note-in order to understand things that I provided table core information do not have to access the core production database tables.

    It could be that useful...

  • Create a db with a simple form application, based on a remote table

    Hello

    I have APEX 4.0 installed on my laptop and a distant DB (always in my local network) with EBS R12 on it.
    I created a dblink with my HR schema and updated my tnsname.ora. Now I can connect and browse the remote db with schema APPS/APPS.
    I can also browse table away from my local db user 'HR '.

    for example: select * from emp@apex_dblink; recover data without problem even if I'm a developer sql or standard interface of APEX with my APEX user.

    As a training, now I want to create an application database from scratch on a tabular presentation with the HR schema. When I browse for the table, I don't see my table 'emp' remote and when I push the "emp@apex_dblink" research, he said only: "emp@apex_dblink is not a valid table name.".

    Some have said, it is because of the 'grant privilege' and 'create the synonym' but I don't know if like my dblink I should think to solve this problem...
    In addition, I do not know much about the administration and do not know where to go...

    Here is some information:

    DB user: hr/hr@XE
    APEX user: ulrich/ulrich-> name of the workspace: APEX_WORKSPACE

    That's your time and your response.

    Apex gets his table & veiw your local database catalog definitions. Are two ways to do what you want:
    (1) create copies of the tables/views you want and create your forms & reports based on these tables/views. Once you have your app work (at least the table/view definitions are now known to Apex), delete local tables and replace them with synonyms for remote tables.

    -- run in local Apex database
drop table emp;
-- I'd recommended naming your DB link after the remote DB name to keep easy track of where it's pointing
-- create database link EBSPROD connect to HR using HR123 identified by 'EBSPROD.world';
-- or include the schema name if you need multiple DB links to that remote DB
-- create database link EBSPROD@hr connect to HR using HR123 identified by 'EBSPROD.world';
-- create database link EBSPROD@scott connect to scott using tiger identified by 'EBSPROD.world';
-- select * from emp@EBSPROD@scott;

create or replace synonym EMP for EMP@apex_dblink;

    (2) create local views to remote objects. Apex point to these points of view the.

    -- run in local Apex database
create or replace view EMP as (select * from EMP@apex_dblink);
