Need different rows from single query based on condition

Hi,
I have a table with 100 rows that holds employees and their roles.
I need to write a SQL(not a PL/SQL block) as below
1. When employee with role 'VP' logs in, the query should return all the 100 rows.
2. When employee with role 'MGR' logs in, the query should return only those rows whose MGR is the logged in employee.
3. When employee with role 'SALE_EXEC' logs in, it should return single rows corresponding to this SALE_EXEC.
My requirement here is to get these outputs from a single query.
Can anyone please help me with this.
Thanks,
Vivek.

New Policy Groups
When adding the policy to a table, view, or synonym, you can use the DBMS_RLS.ADD_GROUPED_POLICY interface to specify the group to which the policy belongs. To specify which policies will be effective, you add a driving context using the DBMS_RLS.ADD_POLICY_CONTEXT interface. If the driving context returns an unknown policy group, then an error is returned.
If the driving context is not defined, then all policies are executed. Likewise, if the driving context is NULL, then policies from all policy groups are enforced. In this way, an application accessing the data cannot bypass the security setup module (which sets up application context) to avoid any applicable policies.
You can apply multiple driving contexts to the same table, view, or synonym, and each of them will be processed individually. In this way, you can configure multiple active sets of policies to be enforced.
Consider, for example, a hosting company that hosts Benefits and Financial applications, which share some database objects. Both applications are striped for hosting using a SUBSCRIBER policy in the SYS_DEFAULT policy group. Data access is partitioned first by subscriber ID, then by whether the user is accessing the Benefits or Financial applications (determined by a driving context). Suppose that Company A, which uses the hosting services, wants to apply a custom policy which relates only to its own data access. You could add an additional driving context (such as COMPANY A SPECIAL) to ensure that the additional, special policy group is applied for data access for Company A only. You would not apply this under the SUBSCRIBER policy, because the policy relates only to Company A, and it is more efficient to segregate the basic hosting policy from other policies.
How to Implement Policy Groups
To create policy groups, the administrator must do two things:
Set up a driving context to identify the effective policy group.
Add policies to policy groups as required.
The following example shows how to perform these tasks.
Note:
You need to set up the following data structures for the examples in this section to work:
DROP USER finance CASCADE;
CREATE USER finance IDENTIFIED BY welcome2;
GRANT RESOURCE TO apps;
DROP TABLE apps.benefit;
CREATE TABLE apps.benefit (c NUMBER);
Step 1: Set Up a Driving Context
Begin by creating a namespace for the driving context. For example:
CREATE CONTEXT appsctx USING apps.apps_security_init;
Create the package that administers the driving context. For example:
CREATE OR REPLACE PACKAGE apps.apps_security_init IS
PROCEDURE setctx (policy_group VARCHAR2);
END;
CREATE OR REPLACE PACKAGE BODY apps.apps_security_init AS
PROCEDURE setctx ( policy_group varchar2 ) IS
BEGIN
REM Do some checking to determine the current application.
REM You can check the proxy if using the proxy authentication feature.
REM Then set the context to indicate the current application.
DBMS_SESSION.SET_CONTEXT('APPSCTX','ACTIVE_APPS', policy_group);
END;
END;
Define the driving context for the table APPS.BENEFIT.
BEGIN
DBMS_RLS.ADD_POLICY_CONTEXT('apps','benefit','APPSCTX','ACTIVE_APPS');
END;
Step 2: Add a Policy to the Default Policy Group.
Create a security function to return a predicate to divide the data by company.
CREATE OR REPLACE FUNCTION by_company (sch varchar2, tab varchar2)
RETURN VARCHAR2 AS
BEGIN
RETURN 'COMPANY = SYS_CONTEXT(''ID'',''MY_COMPANY'')';
END;
Because policies in SYS_DEFAULT are always executed (except for SYS, or users with the EXEMPT ACCESS POLICY system privilege), this security policy (named SECURITY_BY_COMPANY), will always be enforced regardless of the application running. This achieves the universal security requirement on the table: namely, that each company should see its own data regardless of the application that is running. The function APPS.APPS_SECURITY_INIT.BY_COMPANY returns the predicate to make sure that users can only see data related to their own company:
BEGIN
DBMS_RLS.ADD_GROUPED_POLICY('apps','benefit','SYS_DEFAULT',
'security_by_company',
'apps','by_company');
END;
Step 3: Add a Policy to the HR Policy Group
First, create the HR group:
CREATE OR REPLACE FUNCTION hr.security_policy
RETURN VARCHAR2
AS
BEGIN
RETURN 'SYS_CONTEXT(''ID'',''TITLE'') = ''MANAGER'' ';
END;
The following creates the policy group and adds a policy named HR_SECURITY to the HR policy group. The function HR.SECURITY_POLICY returns the predicate to enforce security on the APPS.BENEFIT table:
BEGIN
DBMS_RLS.CREATE_POLICY_GROUP('apps','benefit','HR');
DBMS_RLS.ADD_GROUPED_POLICY('apps','benefit','HR',
'hr_security','hr','security_policy');
END;
Step 4: Add a Policy to the FINANCE Policy Group
Create the FINANCE policy:
CREATE OR REPLACE FUNCTION finance.security_policy
RETURN VARCHAR2
AS
BEGIN
RETURN ('SYS_CONTEXT(''ID'',''DEPT'') = ''FINANCE'' ');
END;
Create a policy group named FINANCE and add the FINANCE policy to the FINANCE group:
BEGIN
DBMS_RLS.CREATE_POLICY_GROUP('apps','benefit','FINANCE');
DBMS_RLS.ADD_GROUPED_POLICY('apps','benefit','FINANCE',
'finance_security','finance', 'security_policy');
END;
As a result, when the database is accessed, the application initializes the driving context after authentication. For example, with the HR application:
execute apps.security_init.setctx('HR');
Validating the Application Used to Connect to the Database
The package implementing the driving context must correctly validate the application that is being used to connect to the database. Although the database always checks the call stack to ensure that the package implementing the driving context sets context attributes, inadequate validation can still occur within the package.
For example, in applications where database users or enterprise users are known to the database, the user needs the EXECUTE privilege on the package that sets the driving context. Consider a user who knows that:
The BENEFITS application allows more liberal access than the HR application
The setctx procedure (which sets the correct policy group within the driving context) does not perform any validation to determine which application is actually connecting. That is, the procedure does not check either the IP address of the incoming connection (for a three-tier system) or the proxy_user attribute of the user session.
Such a user could pass to the driving context package an argument setting the context to the more liberal BENEFITS policy group, and then access the HR application instead. Because the setctx does no further validation of the application, this user bypasses the normally more restrictive HR security policy.
By contrast, if you implement proxy authentication with VPD, then you can determine the identity of the middle tier (and the application) that is actually connecting to the database on behalf of a user. In this way, the correct policy will be applied for each application to mediate data access.
For example, a developer using the proxy authentication feature could determine that the application (the middle tier) connecting to the database is HRAPPSERVER. The package that implements the driving context can thus verify whether the proxy_user in the user session is HRAPPSERVER. If so, then it can set the driving context to use the HR policy group. If proxy_user is not HRAPPSERVER, then it can disallow access.
In this case, when the following query is executed
SELECT * FROM APPS.BENEFIT;
Oracle Database picks up policies from the default policy group (SYS_DEFAULT) and active namespace HR. The query is internally rewritten as follows:
SELECT * FROM APPS.BENEFIT WHERE COMPANY = SYS_CONTEXT('ID','MY_COMPANY') and SYS_CONTEXT('ID','TITLE') = 'MANAGER';
How to Add a Policy to a Table, View, or Synonym
The DBMS_RLS package enables you to administer security policies by using its procedures for adding, enabling, refreshing, or dropping policies, policy groups, or application contexts. You need to specify the table, view, or synonym to which you are adding a policy, as well as the data pertinent to that policy, such as the policy name. Such data also includes names for the policy group and the function implementing the policy. You can also specify the types of statements the policy controls (SELECT, INSERT, UPDATE, DELETE, CREATE INDEX, or ALTER INDEX).

Single query return multiple value

Hi ALL,
I have a sql query as below :
select order_number,
(select decode(hcp.contact_point_purpose,'ABC',hcp.email_address,'CDE',hcp.email_address,null)
from hz_contact_points,
hz_parties hz
WHERE hz.party_id=hcp.owner_table_id) Email
FROM oe_order_headers_all h
WHERE h.order_number='102'
Actually the problem i am facing is the inner select query is returning multiple row , so my main query is erroring out, i need to capture the multiple row.
in the above example the inner decode statement returning two mail address, i need to capture that, but while executing the whole query it is erroring out as saying single query returns multiple values.
please help me on this to capture multiple values
Thanks

>
select order_number,
(select decode(hcp.contact_point_purpose,'ABC',hcp.email_address,'CDE',hcp.email_address,null)
from hz_contact_points,
hz_parties hz
WHERE hz.party_id=hcp.owner_table_id
/* a join is missing here that points to table oe_order_headers_all h*/) Email
FROM oe_order_headers_all h
WHERE h.order_number='102'
>
I can see a join missing in your select sub query.
However, if you you are still getting the single query return multiple value error then you need to replace the sql sub query
select decode(hcp.contact_point_purpose,'ABC',hcp.email_address,'CDE',hcp.email_address,null)
from hz_contact_points,
hz_parties hz
WHERE hz.party_id=hcp.owner_table_id)by decode(hcp.contact_point_purpose,'ABC',hcp.email_address,'CDE',hcp.email_address,null)
and join the two tables in you main query..

Need to get data from multiple database instances in a single query

Hi,
I need a small favour from you guys. The prob is as follows:
I need to get name, row_id from table A from schema 1 and gbu_name, name from table B from schema 2 where a.name = b.name. I wrote the query in the following manner:
SELECT a.name, a.row_id, b.gbu_name
FROM Schema1.A as a, Schema2.B as b
Where a.name = b.name
But this query is not working and the error is like " The table does not exists".
Please update me how to avoid the error and get the right sort of result.
Thanks & Regards,
Debabrata

Ah, youre actually asking different things.
In your topic title, you say youre running separate instances
In your body text, you say you are under different user/schema
So tell me, do you have more than one database or not? How many entries in your TNS file?
I would say, for "multiple database instances"
SELECT
a.id, b.id
FROM
tableA a
INNER JOIN
tableB@OTHER_DATABASE_LINK_NAME b <--NOTE!
USING(id)And of course you will have to look up CREATE PUBLIC DATABASE LINK sql..

       300 999                         777
7 rows selected.I'm supposed to create a SQL that will return me the email, mobile_phone, and home_phone for a set of employees. The result will be something like this:
EMPLOYEE ID | HOME_PHONE | MOBILE_PHONE | EMAIL

666         | 999 |    888      | [email protected]
777         | 444 |    null     | nullThe thing I'm finding difficulty here is that the same column is used to store different values, based on the value in employee_definition table (something like a key/value pair). If I do:
SQL> select emp_id, def_value as email from employee_data, employee_definition
2 where employee_data.def_id = employee_definition.def_id
3 and employee_definition.def_name = 'EMAIL';
    EMP_ID EMAIL
       123 [email protected]
       666 [email protected]'s partially ok.. I'm just getting the definition for 'EMAIL'. But how can I get all the values in a single query, knowing that the column stores different values based on def_name?

Oh no, not again.
Entity attribute models always seem like a great idea to people who have been in the profession for five minutes and lack any kind of fundamental knowledge.
It staggers me that someone with 2,345 posts still believes "you need a 'detail table' for [storing multiple telephone numbers]"
"A person can have multiple telephone numbers" is not an excuse to build a tired person_attribute table. Niether is the bizarre proposal by someone with over 4k posts who should know better in an earlier post that EAV models are necessary to support temporal fidelity.
Taken to it's logical conclusion, EAV modelling leads to just two application tables. THINGS and THING_ATTRIBUTES. And when you consider that a THING_ATTRIBUTE is also a THING, why not roll those two tables up into one also? Hmmm, what does THINGS and THING_ATTRIBUTES look like? I know, TABLES and COLUMNS. Who would've guessed? SQL already provides the completely flexible extensible attribute model the advocates of EAV proscribe. But it also has data types, physical data independence, constraints and an efficient query language which EAV does not.
EAV modelling errodes the semantics of the attributes which are bundled into the "attribute" table.
There is no point in storing 12 different phone numbers with implied functional dependency to unconstrained and often repeating notional attributes like "MOBILE", "LANDLINE", "WORK", err, "WORK2", err, "MOBILE2", err, ... when this phone type attribute has no semantic value. When you want to call someone, you invariably want to retrive the prefered_phone_number which may depend on a time of day, or a call context.
These things need to be modelled properly (i.e normalised to BCNF) within the context of the database.

Need to get total count of a column in the given query

I have a table like above and I am trying to write a query that gets
Count of accounts with deposits made in last 1 month,
Count of accounts with deposits made in last 2 months
Account Count with balance > 0,
Also, I need to join this ACCOUNTINFO with ACCOUNTMAIN to get name etc details

Single query to get data from different databases

i need to capture certain fields from certain tables in database 1 and certain fields from certain tables in database 2 into one file using a single SQL statement.
i tried searching on the net
i found that dblinks can help
but iam not sure if ill be able to create dblinks in my situation which is:
i need to get data from oracle to be copied to mysql
this is not a replication acitivity, but i need certain fields from one database and certain from the other
so what iwas thinking is, if i use an sql query to get all the fields (i need around 40) from the different oracle databases and create a singlefile with one insert per select, i can then read that file into mysql
instead of creating multiple sql queries for each table and creating separate files and eventually separate tables in mysql.
can anyone help me here?
or maybe suggest another approach.
thanks

Hi,
I think dblink is the only option available to get data from different databases. It will work for your case too.
CREATE DATABASE LINK db_link CONNECT TO user_name IDENTIFIED BY password USING 'instance_name'you must have the system privilege 'create database link' to create db links. This way you can get the required data and put it in a table in oracle. But i dont know how to put this data from oracle table to Mysql.

Get a Column value based on other column value in a single query

Hi All,
I have a problem here -
In Table XYZ I have columns by name A, B, C and COL_I. COL_I has a value A or B or C. Based on the value in COL_I, I need to get the value from the corresponding column in the table.
For Ex: If the COL_I has the value as 'A' then I need to fetch the value from the column A. If it is 'B' then fetch from column B.
This has to be done in a single query.
Thanks,

I need to edit sections of several songs into a single track on a CD for a dressage test. Any ideas what software I need to get to achieve this?

Audacity 1.2.5 is an audio editor in which you can assemble and edit your recordings: it's free. I don't think it would burn CDs - you would have to reimport the finished recording into iTunes and burn from there.
Amadeus Lite is $24.99 in the Mac App Store and is in my opinion a better product: it can burn your audio CD directly.
If this is a one-off job you might as well use Audacity: if you are planning on doing this sort of thing at all often you would probably be better off either with Amadeus Lite or Amadeus Pro ($59.99) though this latter may well be over-specified for you as it includes multi-track editing.

Getting result with single query

Hi,
I'm using db 10.2.0.1.0
I have a table emp_shift , with data like below

Suppose
Case 1 : Input Empcode:1 Date:10-jan-2012
Then i should get the below record

Single Query for getting total no of records N getting records from a selected range

Hi,
Got the below query:
SELECT a.*, rowid FROM (SELECT name, postcode FROM Tbl ORDER BY name asc)a WHERE ROWNUM <=30
MINUS
SELECT b.*, rowid FROM (SELECT name, postcode FROM Tbl ORDER BY name asc) b WHERE ROWNUM <= 10
Though I got the results right, I also want to know the total no of records from "SELECT name, postcode FROM Tbl ORDER BY name asc". Does anyone knows how to do it in a single query?
Thanks.

hi Carol
The following output may help you.
SQL> l
1 select * from emp where (rowid,0) in (select rowid,mod(rownum,10)-rownum from emp)
2 minus
3* select * from emp where (rowid,0) in (select rowid,mod(rownum,6)-rownum from emp)
SQL> /
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO
7839 KING PRESIDENT 17-NOV-81 5000 10
7844 TURNER SALESMAN 7698 08-SEP-81 1500 0 30
7876 ADAMS CLERK 7788 12-JAN-83 1100 20
7900 JAMES CLERK 7698 03-DEC-81 950 30
The above query fetches the 6,7,8,9th records only.
Well my suggestion would be not to use ROWNUM directly in where clause since it changes dynamically. it is not a fixed value. for example pls see the result.
SQL> select rownum,empno,ename,sal,job from emp where sal > 3000;
ROWNUM EMPNO ENAME SAL JOB
1 7839 KING 5000 PRESIDENT
SQL> select rownum,empno,ename,sal,job from emp where sal > 1000;
ROWNUM EMPNO ENAME SAL JOB
1 7566 JONES 2975 MANAGER
2 7654 MARTIN 1250 SALESMAN
3 7698 BLAKE 2850 MANAGER
4 7782 CLARK 2450 MANAGER
5 7788 SCOTT 3000 ANALYST
6 7839 KING 5000 PRESIDENT
7 7844 TURNER 1500 SALESMAN
8 7876 ADAMS 1100 CLERK
9 7902 FORD 3000 ANALYST
10 7934 MILLER 1300 CLERK
10 rows selected.
SQL> select * from emp where rownum = 1;
EMPNO ENAME JOB MGR HIREDATE SAL COMM DEPTNO
7566 JONES MANAGER 7839 02-APR-81 2975 20
The record of employee KING is getting the rownum differently.
My understanding (out of my little knowledge) is the rownum values are assigned to the records only after the records are read physically and after applying the conditions(without rownum). Then the row numbers (rownum) is assigned to the records. Hence the rownum is not constant to a record since it is a dynamic value.
Well i would like to know the suggestions of the ORACLE EXPERTS here in the discussion forum.
If my finding is correct then OK if not Pls excuse me and pls give the correct solution
