Grouping few records.. Please help me....

Hi all,,
I have the following doubt.
I have a field by name area and it is filled with many values as shown below
I would like to group them as Locations.
For example
Area
abc1
abc2
abc3
abc4
abc5
abc6
I would like to group first three records and get the result as Location
That means when i run this query i want to name it as Location
Thanks and Regards
Nick

This is even more confusing :
Grouping few records.. Please help me....

It also takes time for the photos to be transferred out of your iPhone and into Photo stream on Apple's iCloud servers.
Note that this can't happen if your iPhone is not connected to a WiFi network:
When you enable My Photo Stream on your devices, all new photos you take or import to those devices will be automatically added to your photo stream.
iOS devices: New photos you take are automatically uploaded to your photo stream when you leave the Camera app and are connected to Wi-Fi. My Photo Stream does not push photos over cellular connections.
Macs: Any new photos you import to iPhoto or Aperture begin uploading automatically when you have a Wi-Fi or Ethernet connection. Or you can change your iPhoto or Aperture preferences so that only photos you manually add to My Photo Stream are uploaded.
PC with iCloud Control Panel 2.0 or later: Open a Windows Explorer window and under Favorites select iCloud Photos if you are using iCloud Control Panel 3.0 (or Photo Stream if you are using 2.0 to 2.1.2). Open My Photo Stream. Click the "Add photos" button. Select the photos to import to My Photo Stream, then click Open.

can anyone tell me a efficient way to insert large number of records? This is urgent.Please help.

This is a sample code i am using in one of my programs. You can try similar way and insert into custom table with every loop pass.
I am considering 2000 records at a time. You can decide the no and code accordingly.
if not tb_bkpf[] is initial.
fetching the data from BSEG for each 1000 entries in BKPF to
reduce the overhead of database extraction.
    clear l_lines .
    describe table tb_bkpf lines l_lines.

      clear: l_start, l_end.

How to restore/view the deleted records - Please help me on this regard

Hi All,
Please help me in restore/view the deleted data.
I had removed 2 records from a table without back up and commited the same. Now I want to restore/view it, can you please guide me on this regard.
Oracle Version: 10g
OS: Windows XP
Database in Archive Mode.

If all what you want is to view the data, you can use the Flashback's as of query which would enable you to go back either by SCN or by Timestamp. If you want to restore those rows back in the time( and losing the changes that has happened in that time ), you can use the Flashback Table option. An example of this is given below,

Aman....As promised, here's one way to use flashback to restore the one deleted row without having to impact the rest of the table with a general FLASHBACK TABLE.

My iPod touch won't turn off. I tried and the turn off slide button in stuck in the of position, but it's still not turning off. It's been a few days please help!!!!

My white 4th generation iPod touchs turn of slide button is stuck on off but my iPod won't turn off for some reason and it only shuts off when the battery dies. It's been stuck like this for some time. Please please please help!!!!

First, try a system reset. It cures many ills and it's quick, easy and harmless...
Hold down the on/off switch and the Home button simultaneously until the screen blacks out or you see the Apple logo. Ignore the "Slide to power off" text if it appears. You will not lose any apps, data, music, movies, settings, etc.
If the Reset doesn't work, try a Restore. Note that it's nowhere near as quick as a Reset. Connect via cable to the computer that you use for sync. From iTunes, select the iPad/iPod and then select the Summary tab. Follow directions for Restore and be sure to say "yes" to the backup. You will be warned that all data (apps, music, movies, etc.) will be erased but, as the Restore finishes, you will be asked if you wish the contents of the backup to be copied to the iPad/iPod. Again, say "yes."
Finally, if the Restore doesn't work, let the battery drain completely. Then recharge for at least an hour and Restore again.

Adobe audition cc crashes after a few times of recording(please help)

Okay so Adobe audition is incredibly useful or should i say WAS... It was great until one day it just crashed after a few times of recording. I just thought maybe something went wrong whatever ill re do it. But no.. for months ive been trying, uninstalling and reinstalling, updating, closing all other programs running but nothing has seemed to do it. Audition is really important to my music career and lately i havent been able to do anything because it doesnt work. Im begging, can someone PLEASE try to help me, im desperate.
heres a pic of what happens when it crashes:

I notice from the picture that you have four files in the middle of processing. Do you remember what they were doingwhen the crash happened? Were they saving or did you have some effects processing going on?
Also either Audition or Windows may have saved a crash report somewhere which could help to diagnose the problem. I am not sure where they may have been saved but others might remember where to look for them.

A few questions -- please help!

I know they may seem long and complex. Any help would be appreciated.
1) Where can we find the detailed description of the database used by
the personalization server (to store user and portal configuration
information)? What steps do we have to go through to set up a database on
the Sybase server?
2) When one portlet fails (throws an exception), the whole portal seems
to fail. How can we avoid that?
3) Can we define our own tags similar to the way they are defined in
the JSP files that come with the product? Such as,
<%@ taglib uri="lib/esportal.jar" prefix="pt" %>
4) We seem to experience problems with the Administration tool. The
layout of portlets on the resulting portal page does not reflect what is
shown in the administration tool. Is there something we have not done
properly? Any suggestions?
5) Are there any built-in EJBs or JSP tags that implement XML parsing
and/or rendering.

Ariyanto,
This is a great explanation. Thanks for going to all that trouble! I will make sure your hard work makes it into the official documentation.
We are currently working hard on simplifying these relationships and would also like to enforce DB level constraints that will make them easier to understand.
Sincerely,
Daniel Selman

Hi, I went through similar confusion when I check out the WLCS tables.
I finally found out that WLCS follow some kind of pattern, which basically achieve a very high flexibility in terms of adding properties.
The following is a bit "phylosophical" (heavy design material) and rather long.
Be very careful not to delete or modify anything from these tables manually because you may upset the configuration you have set using Admin tool.
I start with the table which contains a very small information on the user, wlcs_user. The key in wlcs_user is the identifier (user ID). However, a user, is an considered as an entity. Thus this 2 tables need to be viewed together. Identifier is the human readable key. Entity_ID is the key weblogic uses (in wlcs_entity_id). The key is auto-generated. For user, you may want to check for those with JNDI_HOME_NAME = com.beasys.commerce.axiom.contact.User for example.
However, this relation is one way only (user to entity). Entity can also means other thing (not just user, but may also mean group).
User then has property. Some property which belongs to portlet are controlled by weblogic. You cannot add additional property there, and therefore they exist their own table. However, in Admin Tool you can add custom properties. But first you have to create property set. Property set is stored in wlcs_schema. Within property set, the property can be defined (using Admin Tool) and this is entered in wlcs_prop_md (md = meta data?) AND wlcs_prop_md_integer or wlcs_prop_md_float, etc depending on the type. THIS IS WHAT CONFUSES A LOT OF PEOPLE INCLUDING ME (at least initially).
Similar to wlcs_user, you cannot look at wlcs_prop_md alone. For each record, it has to be combined with the appropriate record from one of the wlcs_prop_md_integer/float/text...etc.
The user can then use this custom property, and the value the user has for this property is stored in the wlcs_prop_md_integer, float, text, etc, depending on the specified type.
This is what is missing from the documentation provided by WLCS. I manage to deduce this after working on it for 1.5 days (with help from a DBA) and using plenty of data and select statement.
Feedback to WEBLOGIC:
1. Please be consistent with naming (meta_data, metadata, md - 3 combination!)
2. Please provide mapping between object and tables. Your enterprise clients will thank you because it makes clear from their side, how their existing table going to work with your table. The faster the tech people understand your internal system, the more comfortable they are with WebLogic, the faster the project can start, the faster PURCHASE ORDER come to your SALES TEAM. Think about it!

Ture Hoefner wrote in message <[email protected]>...
Does this mean that for a given user, WLCS_PROP_TEXT will have one and only one entry/row for a given property (ie. in this case email)?
Yes, if it is a single-valued property.
what happens if I define multiple profiles, using Unified Profile Type? can I store multiple values for the same user and property, email?I may want to create two profiles, one contains my home setting and another contains my work setting. In both, I may want to use same 'email' address but different phones. how can I achieve this?
This is not what the UUP is meant for. The UUP is meant for your custom Users that keep the data for their properties in an existing database instead of the reference implementation. If you create a UUP for a HomeUser and one for a WorkUser, they are different types of User but you won't be able to have a HomeUser and a WorkUser with the same name. They are all Users in your system.
There are many possible solutions to your problem. Here is one: use different property sets. Have a WorkProperties and a HomeProperties. You can have a text property called "CurrentLocation" and use a classifier rule to classify a user as a WorkUser or a HomeUser. Then you can use the PersonalizationAdvisor (with the <pz:div> tag) to get the phone number from the correct property set.
As I said, there are many possible solutions. The user management and rules frameworks are flexible and I have no doubt that you could implement an elegant solution with a little planning.

SOS problem using one Entity bean for editing records. please help me

Hello
I have one great problem using one entity bean 2.1 and i am working with this problem several days and i dont solve it.
i am using this jb 2.1 for add new records to one oracle database and for editing records.
I have one great problem for editing records
I have one objets that is as one of my database table. (PersonaObj.java)
     //personaObj.java
     public class PersonaObj implements Serializable{
          private Integer id_persona; //this ishte database table autonumeric
          private java.lang.String nombre;
          now the set/get methods.
     One field of this objets (bean) is the primary key of the table, and this field is one part of the pk from the entity bean.
     From one session bean i call the entity bena passing the objet
     into the entity bean (interface) i have one methods:
          public getPersona getT56aaat04();
     public void setPersona(PersonaObj obj);
     into the entitybean bean i have:
     public PersonaEntityPK ejbCreate(PersonaObj obj) throws CreateException {
          this.setT56aaat04(obj);
          public abstract Integer getId_persona();
     public abstract void setId_persona(Integer Id_persona);
     public abstract java.lang.String getNombre();
     public abstract void setNombre(java.lang.String Nombre);
     public PersonaObj getPersona() {
          PersonaObj obj = new PersonaObj();
          obj.setId_persona(getId_persona());
          obj.setNombre(getNombre());
          return obj;
     public void setPersona(PersonaObj obj) {
          setId_persona(obj.getId_persona());
          setNombre(obj.getNombre());
But i have one graet problem.
adding new record to the database i runs well but if i want to edit one recor appears this error:
=> Error <=

                    T56aaat04Obj objTmp = new T56aaat04Obj();
                    objTmp.setAp1_a04(obj.getAp1_a04());
                    objTmp.setEstado_a04("false");
                    personaLocal.setT56aaat04(obj);
Please can you help me to solve this problem?

Hello Werner,
The mappings seem to be alright at a first glance.
Have you tried out un- and redeploying your application? Sometimes values appear to be cached in the server. So if you have deployed the application before you entered DB_BANK as alias this might solve the problem...

That's not quite right. From the javadocs:
next
public boolean next()
throws SQLException
Moves the cursor down one row from its current position. A ResultSet cursor is initially positioned before the first row; the first call to the method next makes the first row the current row; the second call makes the second row the current row, and so on.
If an input stream is open for the current row, a call to the method next will implicitly close it. A ResultSet object's warning chain is cleared when a new row is read.
Returns:
true if the new current row is valid; false if there are no more rows
Throws:
SQLException - if a database access error occurs

JDBC Call returns no results, SQL*Plus returns 1 record, Please help!

Any help would be greatly appreciated.
Running 9.2.0.5.0, and using latest 9.2 JDBC 1.4_g drivers in thin mode.
Execute the following query from SQL*Plus and it returns one row, from JDBC using a PreparedStatement, I get no results. Here's the query, table def, record, etc.:
Query:
SELECT
ID_WEB_FRM,ID_WEB_SIT,CDE_LVL_1_FUNC,
CDE_LVL_2_FUNC,NUM_WEB_FUNC_PG,NUM_WEB_PG_ID
FROM
WEB_FRM
WHERE
ID_WEB_FRM = ' '
OR
(ID_WEB_SIT = 'test' AND CDE_LVL_1_FUNC = ' '
AND CDE_LVL_2_FUNC = 'u2T' AND NUM_WEB_FUNC_PG = 1
AND NUM_WEB_PG_ID = 0)
Record returned from SQL*Plus:
ID_WEB_FRM ID_WEB_SIT CDE CDE NUM_WEB_FUNC_PG NUM_WEB_PG_ID
NfRRmc5XZu test u2T 1 0
Both in the data returned and the query, there are no blanks, but they are a single space instead (hard to see in message here).
Java code:
int count = 1;
findDBNameStatement.setString(count++," ");
findDBNameStatement.setString(count++,form.getSiteID());
findDBNameStatement.setString(count++," ");
findDBNameStatement.setString(count++, form.getFunctionID());
findDBNameStatement.setInt(count++,form.getPageNumber());
findDBNameStatement.setInt(count++,form.getSectionNumber());
ResultSet resultSet = findDBNameStatement.executeQuery();
ResultSetMetaData metaData = resultSet.getMetaData();
resultSet.next() returns false

I have verified the parameters and such, and if I run as a Statement instead of a PreparedStatement, the query works fine. After some more troubleshooting, I narrowed the problem down, but not sure of the fix.
If I eliminate teh extra parameters and simplify things to:
SELECT ID_WEB_FRM FROM WEB_FRM WHERE ID_WEB_SIT = 'test' AND CDE_LVL_2_FUNC = 'u2T' AND NUM_WEB_FUNC_PG = 1 AND NUM_WEB_PG_ID = 0
The code works. But if I add the additional WHERE clause of CDE_LVL_1_FUNC = ' ' (has single space), it returns no data (record in the DB has single space in this new column. Query that does not work:
SELECT ID_WEB_FRM FROM WEB_FRM WHERE ID_WEB_SIT = 'test' AND CDE_LVL_1_FUNC = ' ' AND CDE_LVL_2_FUNC = 'u2T' AND NUM_WEB_FUNC_PG = 1 AND NUM_WEB_PG_ID = 0
It appears the JDBC Driver is trimming the parameter when it is a space when set through a PreparedStatement.setString(2," ")

X58 pro-e trying to understand a few things please help me out.

first of all hi
im trying to overclock my cpu to a nice place and in my mind its 4ghz and in my mind its like use 22X200=4ghz=happy me
now realty is when i do that and leave every thing on auto the MB puts too much volts on the V.core like 1.4+ and thats bad for me i do have a good cooler thermaltake frio 220w
so i tried lowering Blck and stuff and i googled stuff and ended up with a good 21X175 with 0 on the V.core only to download a program named cpu-tweaker and nehalemcalc so bare with me the question is coming so i setup the nehalemcalc to 225X21 qpi multi X18 Uncore multi X12 mem multi X6
only to get a warning saying (instability may occur when QPI clock is greater than 4000MHz) and it got me wondering how much did i set my Multi`s so i went and checked but i did not find them in the cell menu so i opened the cop-twaeker to look some stuff up and i found
21X175=good i put that there
7x7x7x19=ram timing good too i put them my self
Uncore X16= bad read under
QPI X18= good after i read in 4.8 mode its set to X18
RAM X3 = i guess its good i put it there too
so i opened up the nehalemcalc 1.3 and used these numbers i found only to read some thing i did not find in cell menu mem multi witch was 6 as minimal
number in the program so whats wrong here how come its giving me deferent numbers in the 2 programs and in cpu-z its showing FSB:Dram 2:6
so where do i find adjust that ratio found in the cpu-z or the uncore multi for that matter !
sorry i know its crazy but i really think thats why i cant go pass the 4Ghz dream BTW i need to add Volts to the cpu as from 3.8 :( so it just might help
out to know every thing to know about this motherboard
my system specc`s are :
core i7 920 d0
X58 pro-e
gtx260
1TBx2 wd
2x3 transcend jetram 1333
thremaltake frio
custom cooler for the IOH(cheap fan on the heatsink :P )

Everything should be fine as long as the recommended max. voltages aren't exceeded. Lots of trial & error involved, within safe limits of course.
Added:I hope that 4.00 is the CPU speed & not the volts applied.
stop loling @ me come please i have a dead time on the rams if i dont like them i can return them
so it is the cpu speed the 4k yes so pleaseeeeeee tell me what kind of volts i should use with this setup lets say 3.8ghz and i know every cpu has its own vlots and all but i need like a refrance that i can work on lets say 3.8ghz needs 1.2v on the v,core 1.5v on ram 1.2 on qpi and so on .. so for 4ghz i need 1.3v,ram1.5,qpi...... some thing easy like that and if it works i will for you sir

Slow SDO_RELATE when using group by.. please help!!

Hi All,
I'm fairly new to the spatial side of Oracle so please go easy on me.
I have 2 tables (a and b), each containing line geometries. There is a one(a) to many(b) relationship between the two.
I want to write a query which selects information from table b where the geometries in table b are completely covered by the geometries in table a, but the returned info is grouped by the rows in table a.
Here's my code:
select
a.route_id,
a.step,
max(b.gritter_status),
sum(b.salt_usage)
from
tbl_routedirs a, tbl_routelinks b
where
a.route_id = b.route_id and
sdo_covers(a.geoloc, b.geoloc) = 'TRUE'
group by
a.route_id, a.step
The query is extremely slow, taking up to 15 minutes to execute...The thing which is confusing me is without the group by clause the statement executes in under half a second.
I have checked all indexes etc - all are valid. I've tried re-ordering the tables in the from clause as ive read this can be a factor, and granted i have little knowledge as to what to swap where but this appeared to have no impact on the speed.
Any suggestions would be warmly welcomed... Thankyou.
Edited by: user8760008 on 27-Aug-2009 07:08 - i copied the script and didnt add the aggregate functions on the selected columns...

If that's the case, please try:
select /*+ leading(a) use_nl(a b) index(b your_index_on_b.geoloc) */
a.route_id,
a.step,
max(b.gritter_status),
sum(b.salt_usage)
from
tbl_routedirs a, tbl_routelinks b
where
a.route_id = b.route_id and
sdo_coveredby(b.geoloc, a.geoloc) = 'TRUE'
group by
a.route_id, a.step
i.e. to have a nested loops join, and take a small table as outer.
Note you may not need all three hints to get the nested loops join plan.

Grouping few records.. Please help me....
