Open cursor for string and select from partition (cannot bind)

Hi,
i don't manage to use a bind variable for a select ... from ... PARTITION(...).
It doesn't work to use something like
open cur for 'select ... from ... PARTITION(:1) where ...' using 'NDAY_20120301';So i have to create the cursor string with string functions each time i change the partition.
But that means, that the string changes each time.
Doesn't that prevent from re-use in library_cache?
best regards,
Frank

So why do you care? Unless you have large numbers of partitions what difference does it make? Bind variables are useful to keep Oracle from doing hard parses of queries that are basically the same but use different filter values. Such as an INSERT statement that uses different values FOR EACH ROW rather
You are just constructing the main (non-filter) part of the query one time and need a single value for the entire query regardless of how many rows - that isn't really a use case for bind variables and isn't going to provide any real benefit.
So the real question is why do you even care about something that wouldn't provide any benefit to you even if you could do it?
Looks like you just want to 'roll your own' parallel processing rather that use, and pay for, Oracle's parallel functionality.
If each partition uses its own tablespace you could filter on the FILE Id of the ROWIDs since the file number will be different for each tablespace and datafile.
1. Determine the list of file numbers for each partitions tablespace.
2. Use a WHERE DBMS_ROWID.ROWID_RELATIVE_FNO (ROWID) = :n filter (or use IN (:n1, :n2))to filter rows based on file number(s) for the partition you want
See DBMS_ROWID.ROWID_RELATIVE_FNO in the PL/SQL Packages and Types doc

Having connected my new iPhone 6 to itunes and setting it up as normal... i transferred music to it as normal but when i open the music app and select a playlist it has a download cloud next to each track...

After connecting my new iPhone 6 to iTunes, i transferred my music as i always have done. After opening the music app and selecting a playlist there is a download cloud next to each track... this is also the case with each podcast. Also once i reconnect the phone to iTunes go to add another playlist, at the top the "sync music" check tick has disappeared. when i re check that box again it says "Do you want to sync this iPhone all data will be erased"
can anyone help at all?
Thank you

Creating and selecting from a dynamic table

Hi,
Iam trying to create a table dynamically and selecting from it in same plsql block, but am getting "table doesnot exist" error. however if i just create a table dynamically and then do a select on it seperately it works..
below is sample code for the same,
working
Line: -----
DECLARE
loc VARCHAR2(20):='bglr';
l_cnt pls_integer;
BEGIN
-- create an employee information table
EXECUTE IMMEDIATE
'CREATE TABLE ' || 'emp_bglr' ||
empno NUMBER(4) NOT NULL,
ename VARCHAR2(10),
job VARCHAR2(9),
sal NUMBER(7,2),
deptno NUMBER(2)
end;
select count(*) from emp_bglr ...works and return me 0 rows
Line: -----
but when i include select in plsql block ..it throws "Table does not exists" error...(iam running below plsql block after dropping the created table)
not working
Line: -----
DECLARE
loc VARCHAR2(20):='bglr';
l_cnt pls_integer;
BEGIN
-- create an employee information table
EXECUTE IMMEDIATE
'CREATE TABLE ' || 'emp_bglr' ||
empno NUMBER(4) NOT NULL,
ename VARCHAR2(10),
job VARCHAR2(9),
sal NUMBER(7,2),
deptno NUMBER(2)
--COMMIT;
END;
Select count(*) into l_cnt from emp_bglr;
dbms_output.put_line('cnt is '||l_cnt);
end;
Line: -----

Becuase your code is first checked for syntax/object existance during compilation and throws an error saying the table does not exist.
Try this:

Issuing certificates for user and clients from different forest/domain

Hello,
at first I would like to say that I have made some researches on this forum and in the Internet overall.
I have AD Forest with ~10 sites all over the Europe, DFL and FFL is 2008 R2, right now we are migrating site by site from old domain (samba) to AD.
Last time I have deployed PKI based on offline root CA and 2 Enterprise acting as 2-node Failover Cluster.
Everything in my AD Forest is OK, I mean, autoenrollment works perfect for users and computers from my forest,
now I need to deploy a certificate (for test) to one web-based pbx server in samba domain, there are no trusts etc. Samba domain as well as AD Forest are working on the same network, with routeable subnets in each site, so there is no problem with connectivity,
What are possible way to achieve this goal? I mean to issue cert to client from different forest, so that this client is able to validate it, validate certificate chain and renew it when needed?
I have Installed and Configured CE Web Service and CE Policy Web Service. Now I have configured Enrollment Policies on my virtual machine (being part of different domain), I selected username/password authentication, I am able to request certificate, I can
see all templates which I should see, but when I try to enroll I got an error:
(translated from my language)A certification chain processed correctly, but one of the CA certificates is not trusted by the policy provider
My root CA cert is added to trusted publishers for computer and user node as well.
What could be wrong? If you have any ideas or questions, please share or ask.
Thank you in advance.

Everything is clear, I have Certificate Enrollment Web Services installed and configured,
problem is what i get from certutil - TCAInfo

What is the defference between select single * from and select * from Where

What is the defference between select single * from and select * from Where
which is prefferable and best one.

Hai,
*Difference Between Select Single and Select * from table UpTo One Rows:*
According to SAP Performance course the SELECT UP TO 1 ROWS is faster than SELECT SINGLE because you are not using all the primary key fields.
select single is a construct designed to read database records with primary key. In the absence of the primary key, it might end up doing a sequential search, whereas the select up to 1 rows may assume that there is no primary key supplied and will try to find most suitable index.
The best way to find out is through sql trace or runtime analysis.
Use "select up to 1 rows" only if you are sure that all the records returned will have the same value for the field(s) you are interested in. If not, you will be reading only the first record which matches the criteria, but may be the second or the third record has the value you are looking for.
The System test result showed that the variant Single * takes less time than Up to 1 rows as there is an additional level for COUNT STOP KEY for SELECT ENDSELECT UP TO 1 ROWS.
The 'SELECT SINGLE' statement selects the first row in the database that it finds that fulfils the 'WHERE' clause If this results in multiple records then only the first one will be returned and therefore may not be unique.
Mainly: to read data from
The 'SELECT .... UP TO 1 ROWS' statement is subtly different. The database selects all of the relevant records that are defined by the WHERE clause, applies any aggregate, ordering or grouping functions to them and then returns the first record of the result set.

Day of year bug - format date/time string and scan from string?

I've noticed that the day of year returned by "Format Date/Time String.vi" starts with a value of 1 for Jan-1 while "Scan from String.vi" wants a 0 index. Is this a bug or feature?
(I'm using Labview 2010 Service Pack 1)

I think the best idea is to use seconds since for your arithmetic, because it is going to be the most consistent and robust solution. Knowing that a day has 86400 seconds is all that is needed and you won't run in possible inconsistencies with date time implementations caused by our anything but logic calender. I would hazard that the functionality of converting a timestamp into year and day of year and back is impossible to make consistent without sacrificing other possibly conflicting transformation in the Timestamp into String and Timestamp from String manipulations.
"Seconds since" being the actual base unit in all LabVIEW timestamps, it is best to do any arithmetic on it in this base unit.

I Have Elements13 and Apple Yosemite: When I open the organizer, import and select folder it locks up.

I am using PS Elements 13 with Apple Yosemite. When I open the Organizer, import and select folder, it locks up.

I Did what you said. But when I click on Folders and try to open a sub folder it still locks up. All of the media I have opened is not divided into folder. Is there any way to remove all of them and start over? I have been using Bridge with PSE13 and it work great. With Organizer I get missing files. My organizer PSE12 works ok on my laptop.

DTW template to import opening Balences for BP and Items

Hi all,
Is there any DTW template to import opening Balences for BP and Items
Thanks & Regards,
Naresh K

Naresh,
When you are talking about opening balances of BP and Items, I believe you are talking about Open AR and AP transactions and Opening Stock for Items.
If this is the case then,
For BP Opening Balance, you will need to import them as AR and AP Service Invoice using the template inside folder oInvoices and oPurchaseInvoices
For Opening Stock, you will use template inside oStockTaking

SELECT DISTINCT With OPEN cursor FOR

Hello.
I have the following procedure. All it does is open a cursor for an SQL string passed into it, and return the open cursor.
PROCEDURE sp_execute_dynamic (hold_input_string IN CLOB,
hold_cursor OUT hold_cursor_type) IS
BEGIN
OPEN hold_cursor FOR TO_CHAR(hold_input_string);
END sp_execute_dynamic;
It works fine except when I perform SELECT DISTINCT. I get the following error.
SQL> declare

Thanks
Chris

see at line 7 you are selecting only one column and at line 9you are fetching into two variables
7 dynamic_sql_pkg.sp_execute_dynamic('select distinct object_name from user_objects where object_
name in (''PLAN_TABLE'',''DBA_OBJECTS'')',hold_cursor);
