SQL & PL/SQL :: How To Restrict User (Schema) From Deleting Data From Table
Nov 2, 2012
I want to know how to restrict a user(Schema) from deleting the values from a table created in the same schema.
Below is the example.
I have created a table employee in abc schema which has two values.
EMPLOYEE
ABC
XYZ
In the above scenario the abc user can only fire select query on the EMPLOYEE table.
SELECT * FROM EMPLOYEE;
He should not be able to use any other DML commands on that table. If he uses then Insufficient privileges error should be thrown.

There is a requirement in my database that I want to restrict the user from directly running queries on database from third party tools such as pl/sql developer and toad.
There is a utility in SQL product_user_profile through which this can be done but it is only restricted if you run the query through sql plus. If I want to restrict and (give suppose select,insert) to a user for directly running queries through PL/SQL.

Suppose there is customers table and the user (Scott) is having select,update,insert privelege on the customers table.
a.)From the form i.e GUI he is having all the access,we want that when he logs on with sql plus directly then he would only be able to run select query only.
b.)When we are using third party tools such as pl/sql developer tools and toad then we are not able to restrict the user by running only the select queries.The utility which was used previously was only used for SQL Plus.
Resolution:
a.)I am able to restrict the user when he logs on with sqlplus and he is able to run anly select queries.
b.)How we can restrict the user so that in pl/sql he is able to issue only the select query.
Trigger the user when logs on session id is captured and user can be restricted in logging in to the plsql developer and toad applications

We have an application with database Oracle 10g.
I want to add a new validation to restrict concurrent user and/or session from a client. (we have almost 60 client firms using the software to enter daily trasnactions). All users from all clients are connecting to the database using a common functional ID.
What I did was:
1) Add a column 'user_logged_in' in the master table for client and update it as Y when user from that client logged on to the system,
2) Insert the application logon details (we can figure out the client details from this) into a global temp table,
3) Create a logoff trigger to update the 'user_logged_in'flag in client master table by using values from global temp table when session logged off and
4) Restrict the users from same client if the flag is 'Y'
But the problem in this case is logoff trigger will not be executed in case if the session got killed or terminated abnormally.

I have got 2 users as user1 and user2.I have used the following statements from user 'user1':
create role GENEVAOBJECTS;
grant select, insert, update, delete on PRODUCT to GENEVAOBJECTS;
grant GENEVAOBJECTS to user2;
In the above statements, product is a table. Now, I could able to access this table from user 'user2'. But however if I write a procedure in user2 schema accessing the table product, then the procedure is not getting compiled.
create or replace procedure test_prc as
v_test number(9);
begin
select product_id into v_test
from PRODUCT where rownum=1;
[code]...
why I cannot access that table from procedure?

We have an application with many separate databases (one per customer). Given they share the same business requirements (service hours, change mgmt etc), we're interested in potentially consolidating the separate DBs (which are relatively small) into separate schemas within a fewer no of databases to reduce the overhead.
Our issue is that the application is hard-coded to use a specific administrator and application connection user name. Changing this is unfortunately not an option.
Given this limitation, is there any possibility to map a generic user into a customer-specific schema based on the database service that they connect to? Each customer connects to different database services but may use the same user name. We considered using private synonyms but this seems to acheive the opposite (i.e. many different users could connect and map to a single users schema). One thing to point out is that where there is a single user name, it is acceptable for a single password to be used across the different customer DBs as they will be a single admin/user.

I have a sale invoice form with 3 data blocks.
Data block 1- master_blk : For date/customer of sale invoice
Data block 2- detail_blk1 (detail of the master block - For products and qty)
Data block 3- detail_blk2 (detail of DETAIL_BLK1 For entering serial numbers of products)
My requirement is that whatever quantity user enter in data block 2 against each product he must enter equal number of serial numbers of that product in data block 3.
For this I have created on item (cnt_iteml : to count product's serial numbers in block3 ) in data block 2, and on summary item (t_serial_no ) in block3.
Whenever user changes in quantity, cnt_iteml: item is populated with t_serial_no in block3 of that product by following trigger on quantity column.
POST-Change Trigger ( quantity column )
:stock_transactions.cnt_itl:=:serial_numbers.t_serial_no;
Following trigger is written on block level at data block-3 to populate cnt_iteml with t_serial_no.
PRE-RECORD
IF GET_BLOCK_PROPERTY('SERIAL_NUMBERS',STATUS) IN ('CHANGED') THEN
:stock_transactions.cnt_itl:=:serial_numbers.t_serial_no;
END IF;
Above triggers are fulfilling my requirement except following condition.
If user after entering serial numbers in block 3 and without saving goes back to block2 and try to navigate to another record he gets a message asking him to save changes by forms. At this time if user presses no then cnt_itl item is not been populated with t_serial_no item's value.
What I want in above condition is that if user was inserting new record cnt_it item should be populated with 0, so that he shouldn't be able to save this record. And If he was updating then cnt_itl item should be populated with actual no of records in database against that product.

I need to insert data from one schema table to other schema's table in same database.The thing is columns are not equal.so when I am trying to use insert statement it is throwing error as not enough values. The situation is explained clearly below.The insert stmt is implemented in second schema whose table name is b.
SQL> create table a(ID_A NUMBER,Name varchar2(10),rollno NUMBER,address varchar2(10));
Table created.
SQL> insert into a(ID_A,Name,rollno,address)values(1,'ravi', 101,'hyd');
1 row created.
SQL> insert into a(ID_A,Name,rollno,address)values(2,'rav', 102,'delhi');
1 row created.
SQL> insert into a(ID_A,Name,rollno,address)values(3,'ra', 103,'chn');
1 row created.
SQL> create table b(ID NUMBER,Name varchar2(10),rollno NUMBER,address varchar2(1
0),route varchar2(10),direction varchar2(10));
Table created.
SQL> ALTER TABLE B ADD
2 CONSTRAINT B_PK1
3 PRIMARY KEY
4 (ID);
Table altered.
SQL> create sequence b_seg start with 1;
Sequence created.
SQL> insert into b select b_seg.nextval,lexcom.a.* from lexcom.a,dual;
insert into b select b_seg.nextval,lexcom.a.* from lexcom.a,dual
*
ERROR at line 1:
ORA-00947: not enough values
So,for table b in ID column sequence needed to be inserted and other columns need to be taken from table a.I can understand the error is because two tables are not having equal columns.So,the insert stmt is throwing error.
I can manually write by taking columns from a and b and write insert stmt as follows,but this is tedious process.
SQL> insert into b(ID,Name,rollno,address)select b_seg.nextval,lexcom.a.Name,lex
com.a.rollno,lexcom.a.address from lexcom.a,dual;
3 rows created.
But this is time taking and I had tables which has many columns to be inserted.So is there any other way to solve it and implement insert stmt.

I have been using MSaccess to do some updating and deleting of data.I have 2 tables, 1 with data, 1 with the criteria to change, 2 colums (FINDWORD and REPLACEWORD).
The main table has lots of data, and the SQL query im using in access looks like this:
UPDATE TABLE1, tblFindReplaceWords SET CleanList.COLUMN-NAME = Replace([TABLE1].[COLUMN-NAME],[tblFindReplaceWords].[FINDWORD],[tblFindReplaceWords].[REPLACEWORD]);
how would I go about doing the same thing in orcale?

I am trying to access and modify data of a table of another schema which contains 80,000-90,000 records. My procedure is taking near about 30 mins to complete the operation. faster access and updation of table data.
Details:
I have two schema: TEST and PROD
I am running the below code from TEST Schema.
/* CODE START HERE*/
DECLARE
exc_bulk_errors EXCEPTION;
PRAGMA EXCEPTION_INIT (exc_bulk_errors, -24381);
v_block_count NUMBER := 1000;
[Code]....
The above code is taking near about 30mins to process.
I have also tried another approch: Creating a procedure in PROD schema to update COMPONENT_MASTER table and by calling the procedure from above code by passing component code.
/* PROCEDURE CALL FROM ABOCE CODE INTEST SCHEMA*/
PROD.PROCEDURE_TO_UPDATE(v_comp_code);
But still it is taking same time.

I have a table which contains secret data, i want that nobody can query,insert,update or delete that table, we can do by creating a table and giving rights to specific person but problem is that our programmers can query that table while working on that database.
Is there any other event or trigger which check that if person is performing DML on secret table then an error may generate.

I've a primary database and a physical standby.Logs are shipping perfectly from primary to standby.The logs that are applied on the standby are getting stored in a mount point(LINUX-/opt2) which consumes more space(160 GB). Will that be right if I go ahead and delete them?
My rman configurations in primary is:
RMAN> show all;
using target database control file instead of recovery catalog
RMAN configuration parameters are:
CONFIGURE RETENTION POLICY TO REDUNDANCY 4;
CONFIGURE BACKUP OPTIMIZATION OFF; # default
CONFIGURE DEFAULT DEVICE TYPE TO DISK; # default

Consider tables A,B,C,D,E,F. all are having 100000++ records Tables B,C,D are dependent on table A (with foreign key constraint). When I am deleting records from all tables, table B,C,D are taking max 30-40 seconds while table A is taking 30-40 mins. All tables are having indexes.
Method I have used:
1. Created Temp table
2. then deleted all records from B,C,D,E,F for all records in temp table for limit of 500.
delete from B where exists (select 1 from temp where b.col1=temp.col1);
3. why it is taking too much time for deleting records in table A.

I'm testing a procedure which loads data into my database, and after each test I want to empty some of the tables and reset the sequences. I have this script to do that...
DELETE FROM COM_MERGE;
COMMIT;
DELETE FROM COM_TITLE;
COMMIT;
DELETE FROM COM_ISSUE;
COMMIT;
DELETE FROM COM_PAGE_ELEMENT;
COMMIT;
DELETE FROM COM_ELEMENT;
COMMIT;
DELETE FROM COM_STORY_TITLE;
COMMIT;
BEGIN
COM_RESET_SEQUENCES;
END;
Today I added the call to the sequences procedure to my script, but I have been using the script to delete from tables for a number of days without problem.However today I am finding that when I run the script it works ok the first couple of times, but when I try running it for a third time, it hangs after the second delete (in other words it stops when it gets to the delete from COM_ISSUE). After this happened the first couple of times I stopped the db and restarted it, then the script was ok twice, but again I'm finding that the script hangs. There is no error message, but the script fails to complete.
I didn't know if it was because originally I had one commit at the end of the script, so I added commits after each delete but that didn't solve it.I am using SQL Developer but I have found the same problem when running the script from SQL Plus.This is the definition of the COM_ISSUE table (just in case the table is the source of the problem).There is only one row in COM_ISSUE.
CREATE TABLE "BILL"."COM_ISSUE"
(
"CI_ID" NUMBER NOT NULL ENABLE,
"CI_TITLE" NUMBER NOT NULL ENABLE,
"CI_DATE" NUMBER NOT NULL ENABLE,
"CI_PRICE" NUMBER NOT NULL ENABLE,
"CI_PUBLISHER" NUMBER NOT NULL ENABLE,
CONSTRAINT "COM_ISSUE_PK" PRIMARY KEY ("CI_ID") USING INDEX PCTFREE 10 INITRANS 2 MAXTRANS 255 COMPUTE STATISTICS STORAGE(INITIAL 65536
