Update several rows with single query (easy question, I guess)

Hi all!
I have table with two columns - name and value.
I populate it with several sql queries:
insert into settings (name, value) values ('company_name', 'My Company');
insert into settings (name, value) values ('company_address', 'Company Address 12');
insert into settings (name, value) values ('company_city', 'South Park');
How can update rows with company_name and company_city in single query?
Thank you in advance!

How can update rows with company_name and company_city in single query?I guess something like this was meant:
update settings set value = ??? where name in ('company_name ', 'company_city');But it's still unclear to me what should be used instead of question marks... :)
Regards.

Looping SelectedItem values in HttpService to Update Several Rows in Database in Flex

Hi,
My client wanted me to create something that allows certain
DataGrid to display to allow users to edit and update the database
records. The only dilemma I am having here is how to actually
create something from Flex's end to allow users update several rows
of the database at once. Since everything in my datagrid would be
defined as selectedItem whenever a user accesses the entry, how can
I get Flex to recognize each of the updated variables while I
update the database?
Another question is, if I do something like
dg2.selectedItem.id, it would only display the "selectedItem," and
since I intend to loop every single one of the values as such in
the datagrid to be updated, is it possible to do something like dg.
.id? I tried to do this, and I kept on getting errors.
If anyone could refer me to some examples on how to get this
to start, it would be great.
Thanks in advance.

This is the current code I have:
<mx:HTTPService id="save_scenario" method="POST" url="
http://localhost/save_scenario.php"
useProxy="false">
<mx:request xmlns="">
<scenario_name>{scenario_name}</scenario_name>
<id_no>{dg2.selectedItem.id}</id_no>
<region_name>{dg2.selectedItem.region_name}</region_name>
<population>{dg2.selectedItem.population}</population>
<market>{dg2.selectedItem.market}</market>
</mx:request>
</mx:HTTPService>

Thanks, but I think I will be a little more explicit here
about what I really wanted to know. My impression is that if I have
a DataGrid and that I would like to allow users to edit certain
entries within the actual grid and have all of it saved to the
database, I could use a for loop and just update everything without
paying attention to what has really been updated, but I have been
struggling with how to pass it all to the variables side.
Currently, I could update things one entry a time, by using the
code I provided earlier, but is there a way of which I can have it
all posted to the HTTPService in one go?
Note: I tried using dg.
.id_no in the for loop to iterate over the variables I intend to
post, but I don't think I am allowed to do so, do I?
Alice
Attached is what I used in a PHP script to allow the code
loop around the users' edits, how could I do the similar thing in
Flex by assigning the index variable to something more dynamic?

Single report with multiple queries OR multiple reports with single query

Hello Experts,
I have a confusion regarding Live Office connection for many days. I asked many people but did not get a concrete answer. I am re-posting this question here and expecting an answer this time.
The product versions that I am using are as follows:
FrontEnd:
BOE XI 3.1 SP4 FP 4.1
Xcelsius Enterprise 2008 SP4
Backend:
SAP BW 7.0 EHP1
I have created a dashboard which is getting data from a webi report using LO connections.
The webi report has five report parts which are populated by five different queries.
Now my question is, when the five LO connections are refreshed, is the webi report refreshed five times or just once?
If the report is refreshed five times, then I guess it is better to have five different webi reports containing single report part, because in that way we can prevent same query being executed multiple times.
SO what is the best practice- to have a single report having multiple queries - OR - to create multiple webi reports with single query?
Thanks and Regards,
PASG

HI
I think Best Practice is Multiple reports with single query
Any way If LO connections refresh 5 time the query will refresh 5 timesRegards

Updating multiple rows with different values

Hi!
I have a problem. I need to update more then 1000 rows with different values. How can I do it?
For exsample i have table:
id; color, date,
1 red
2 green
3 white
I need to update date field.
Update table
set date='01.02.03'
where id=1
Update table
set date='01.03.03'
where id=2
Maybe there is way how to update multiple rows at one query?
Sorry for my bad english.
Thanks!

Hi,
You can try this
UPDATE TABLE SET DATE = CASE
                    WHEN ID = 1 THEN TO_DATE('01-02-03','DD-MM-RR')
                    WHEN ID = 2 THEN TO_DATE('01-03-03','DD-MM-RR')
                    ENDcheers

How can update two rows in one query?

How can update two rows in one query?
Edited by: OracleM on May 4, 2009 12:16 AM

What do you mean with "two rows"? May be two columns??
If the where clause of UPDATE query matches two rows, then it will update two rows. If you want to update two columns, then add column names to your query
UPDATE your_table SET col1=value1, col2=value2 WHERE your_where_clause- - - - - - - - - - - - - - - - - - - - -

Single Update command to update multiple rows with multiple rows

Hi Gurus!
Can I update table A with a result set of table b (multiple rows returns) where a.c1 = b.c1
regards,
SH

As Joel mentioned this update will update all rows in a table based on another one:
update tableA set seq_no = (select seqno from tableB where tableA.ID = tableB.ID)
Also, any rows that don't match the select criteria will get updated to null. This could be very bad depending on what you want to do.
To update a subset of tableA with data from tableB:
update tableA set seq_no = (select seqno from tableB where tableA.ID = tableB.ID)
where exists (select 1 from tableB where tableA.ID = tableB.ID)

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).

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

Select top row in Single Query?

Hi
Can somebody help me to write a query to get the first row after order by clause using single query alone.
Example:
I can write following query to select first row
select * from (selec * from t order by col1) where rownum = 1;
But here I should not use inline view to get the result. Because my original requirement needs to use this query in select list and it needs to use a column (of a table from the FROM clause) in the where clause of inline query. Because there is restriction that we can not use the column (of a table from the FROM clause) more than one level of inline query.
Please help me.

What Oracle version are you?
If you have 12c you can use
select col1,...
from t
order by col1
fetch first 1 row only;
If less than 12c, you have can't do it without a subquery.
What are you actually trying to do? Read Re: 2. How do I ask a question on the forums?
and follow the advice there by giving example create table and insert sample data statements and
explaining clearly what you are trying to do. Then we can help more.

Updating a table with a query that return multiple values

Hi,
I'm trying to update a table which contain these fields : ItemID, InventoryID, total amounts
with a query that return these values itemId, inventoryid and total amounts for each items
Mind you, not all the rows in the table need to be updated. only a few.
This what i wrote but doesn't work since the query return multiple values so i can't assign it to journalAmounts.
UPDATE [bmssa].[etshortagetemp]
SET JournalAmounts = (SELECT sum(b.BomQty) FROM [bmssa].[Bom] b
JOIN [bmssa].[SalesLine] sl ON sl.ItemBomId = b.BomId
JOIN [bmssa].[SalesTable] st ON st.SalesId = sl.SalesId
WHERE st.SalesType = 0 AND (st.SalesStatus IN (0,1,8,12,13)) AND st.DataAreaId = 'sdi'
GROUP BY b.itemid, b.inventdimid)
Any advise how to do this task?

Remember that link to the documentation posted above that explains exactly how to do this. When you read it which part exactly were you having trouble with?

Deleting several rows from a query

I have a query with several rows that have a field with the
string "2 by 4" that I would like to delete. There are other rows
where this same field is "2 by 2" and I don't want to delete those
rows.
What's the syntax? Can I use structdelete? Or is this
data-structure an array?

Use the where clause of your sql to select only the records
you want. If you actually need all the records you are getting now,
and you also want a subset of those records, use query of queries
to get your subset.

Updating Multiple Rows With A Sequence

I'm trying to update multiple rows of data in one column based on if its date is greater than a certain date. Starting with the lowest date from those dates I'll give it a 2000 and every ascending date from that point will be another number in sequence (2001, 2002, 2003, etc.).
Apologization Edit:
11g XE
Edited by: spysmily1 on Jun 4, 2012 5:50 PM
Edited by: spysmily1 on Jun 4, 2012 5:51 PM

I would use a counter and start at a specific number. Then I would try to keep updating with this number and incrementing each time. The part I can't quite grasp is how to use this number with the lowest record and apply this sequence to each date that ascends from there. What I was going to try to come up with is something like:
DECLARE
counter := 2000;
BEGIN
loop
update table_name
set column_name = counter
where date > specified date;
counter := counter + 1;
end loop;
This is my first thought but I couldn't see a way to just update the first one that is greater than the specified date and then keep cycling through the dates until the last date(most recent). I know I would need a loop but what can I set that loop to so it would know when to stop. I could use a variable I know is less than the total amount that need to be altered.
