Update with exists and subquery

Hi how to pass index to this sql
Table pap ( eqid,seq,histseq,docno,status,value1,value2)
PK(eqid,seq,histseq) and indx (docno)
table pa ( eqid,seq,docno,status,value1,value2)
PK(eqid,seq) and indx (docno)
update pa
set (value1,value2) = (select pap.value1,pap.value2 from pap
where pap.eqid = pa.eqid
and pap.seq = pa.seq
and pap.histseq =1
and pap.docno <> pa.docno
and pap.status = 4 )
where pa.status=1
and exists ( select 1 from pap
where pap.eqid = pa.eqid
and pap.seq = pa.seq
and pap.histseq =1
and pap.docno <> pa.docno
and pap.status =4 )
It is doing fulltable scan on pa and using hash join .
How to write update with subquery method also ?

There's nothing wrong with a full scan.

We have 2 iphone 4s which have just been updated with IOS5 and whilst setting up icloud the phone contacts were merged and now i have lost my phone contacts on first iphone 4 which have been replaced with phone contacts from my second iphone 4. help?

We have two Iphone 4 handsets. I updated first handset with IOS5 and activated Icloud with my existing Itunes account details - no problems. I then did the same on the second handset and instead of setting up a different Icloud account for the second hanset I mistakenly used the same details as on the first handset and merged the contacts thinking it would add all contacts to both handsets but it instead replaced contacts from first handset with those from the second handset.
How do I get back my contacts from the first hanset?
I read somewhere Icloud saves the last 3 backups which suggests all my contacts that have disappeared are somewhere but how do i find them ???
Help ???

Here's how to do it.
1. App Store, iTunes Store should have the same AppleID on Computer and iPhones. (Free to share apps, music and books... )
2. Person A uses the same purchasing account for everything (ie. email, contacts and ...).
3. Person B have the same purchase account see no. 1 (for App Store and iTunes Store) but create a second AppleID for iCal, e-mail, contacts and etc.

Update with join and group by

Hello All,
I'm trying to update several colums of a table from a inner join query.
First a retrieve the rows afected and the values that I need for the update (I call this subquery ED_Query).
It's important to note that this subquery has a group by and and having clause.
My first attemp (using the query that work in SQL Server query) fails:

The subquery (ED_Query) work fine in Oracle, so I suspect that the problems are when I mix it with the update clause.

I have 2 tables. I like to update one of them (ED_Update) with the data from the another one (ED_Query).
This example is equivalent:
create table ED_Query (id number,
     date01 date,
number01 number)
insert into ED_Query values (1, to_date('01/01/2013','DD/MM/YYYY'), 10);
insert into ED_Query values (2, to_date('01/01/2013','DD/MM/YYYY'), 20);
insert into ED_Query values (3, to_date('01/01/2013','DD/MM/YYYY'), 30);
insert into ED_Query values (4, to_date('02/01/2013','DD/MM/YYYY'), 40);
insert into ED_Query values (5, to_date('03/01/2013','DD/MM/YYYY'), 50);
create table ED_Update (date01 date,
          numberMax number,
          numberSum number)
insert into ED_Update values (to_date('01/01/2013','DD/MM/YYYY'), 0, 0);
insert into ED_Update values (to_date('02/01/2013','DD/MM/YYYY'), 0, 0);
insert into ED_Update values (to_date('03/01/2013','DD/MM/YYYY'), 0, 0);
The next update query fails with ORA-00933: SQL command not properly ended.
update ED_Update
set ED_Update.date01 = ED_Query.date01,
     ED_Update.numberMax = ED_Query.numberMax,
     ED_Update.numberSum = ED_Query.numberSum
inner join
     select date01, max (number01) as numberMax, sum(number01) as numberSum
     from ED_Query
     where date01 = TO_DATE('01/01/2013', 'DD/MM/YYYY')
     group by date01
) ED_Query
on ED_Update.date01 = ED_Query.date01
I think the problem is in the update clause because the next query work:
select * from
ED_Update
inner join
     select date01, max (number01) as numberMax, sum(number01) as numberSum
     from ED_Query
     where date01 = TO_DATE('01/01/2013', 'DD/MM/YYYY')
     group by date01
) ED_Query
on ED_Update.date01 = ED_Query.date01
Thank in advance.

Gr Ir Assignment Updation with PO and Line Item

In the GL for GR IR Account the sort key was not maintained with PO number due to which the assigment field in the line item was getting updated with the posting date and not with the PO & LIne Item details.
We have made the requiste changes and new items are getting updated properly.
But require assitance in updating the earlier line items.
As of date total line items are more than 0.15 mn.
Please suggest some method to automatically update the assigment field of the GR IR Line items with the PO Details.
Regards
Mukesh

Hi,
You can use a substitution to update the field through FI. Use GGB4 for wirting a substitution you may need some ABAP coding to substitute PO no and line items in the assignment field. rule would be Co code =XXX and GL account =xxx and Posting date earlier than =xxxx then concatenrate EBELN and EBELP in Assigment field Zounr.
Then execute FBL3N and edit the assignment field by selecting all the documents and then save it you should see the PO line items populated. You can leave the substitution on or you can remove it after updating,
Regards
K.R

WorkFlow get triggered even if we set trigger for item update with SPEmailEventReceiver and workflow attached to same Library

Hi All,
I have a situation, SPEmailEventReceiver and WorkFlow is attached to same library, WorkFlow is configured to run after item is updated, but soon as the email is received in library the workflow
is getting triggered, We have a action to create folder with subject and date and put the attachment with the date folder in SPEmailEventReceiver e.g: once a mail is received in library the SPEmailEventReceiver will create a folder with Subject and then Folder
with Date and then put the attachment in the date folder so hierarchy will be subject folder/Date folder/attachment
I have tried to alter the SquenceNumber attribute in Feature Element file to 1 and make the Synchronization as synchronous but no luck.

Auxiliary table (other than with as and subquery)

Hello my friends
I know that two ways of implementing tempolary tables are with-as-select and also subqueries.
is there any other way to have auxiliary tables in oracle?
I use oracle 11.2.0.2
thank you in advance.
(i should mention that before asking i searched google)
best,david

yes i meant somehow temporary table, auxiliary table, by with-as oder subquery i just wanted to give example(maybe not a relevent example)Does the word TEMPORARY in Temporary table refers to the state of the Data in the table or the State of the table itself?
Becuase GTT (Global temporary table) is actually a physical table in Oracle with different level of data persistency (Transaction level and Session Level)
SQL Server offers temporary table in which the table itself is not persistent. The table is automatically dropped (Not sure how it works, as not an experienced SQL Server person)
The WITH clause in SELECT is Just a Named Query. Oracle optimizer can materialize the result set of the subquery in the WITH clause and reuse it.

Using OleDbDataAdapter Update with InsertCommands and getting blocking locks on Oracle table

The following code snippet shows the use of OleDbDataAdapter with InsertCommands. This code is producing many inserts on the Oracle table and is now suffering from contention... all on the same table. How does the OleDbDataAdapter produce
inserts from a dataset... what characteristics do these inserts inherent in terms of batch behavior... or do they naturally contend for the same resource.
oc.Open();
for (int i = 0; i < xImageId.Count; i++)
// Create the oracle adapter using a SQL which will not return any actual rows just the structure
OleDbDataAdapter da =
   new OleDbDataAdapter("SELECT BUSINESS_UNIT, INVOICE, ASSIGNMENT_ID, END_DT, RI_TIMECARD_ID, IMAGE_ID, FILENAME, BARCODE_LABEL_ID, " +
   "DIRECT_INVOICING, EXCLUDE_FLG, DTTM_CREATED, DTTM_MODIFIED, IMAGE_DATA, PROCESS_INSTANCE FROM sysadm.PS_RI_INV_PDF_MERG WHERE 1 = 2", oc);
// Create a data set
DataSet ds = new DataSet("documents");
da.Fill(ds, "documents");
// Loop through invoices and write to oracle
string[] sInvoices = invoiceNumber.Split(',');
foreach (string sInvoice in sInvoices)
    // Create a data set row
    DataRow dr = ds.Tables["documents"].NewRow();
    ... map the data
    // Populate the dataset
    ds.Tables["documents"].Rows.Add(dr);
// Create the insert command
string insertCommandText =
    "INSERT /*+ append */ INTO PS_table " +
    "(SEQ_NBR, BUSINESS_UNIT, INVOICE, ASSIGNMENT_ID, END_DT, RI_TIMECARD_ID, IMAGE_ID, FILENAME, BARCODE_LABEL_ID, DIRECT_INVOICING, " +

// Add the insert command to the data adapter
da.InsertCommand = new OleDbCommand(insertCommandText);
da.InsertCommand.Connection = oc;
// Add the params to the insert

Here is what Oracle is showing as blocking locks and the SQL that has been identified with each of the SIDS. Not sure why there is contention. There are no triggers or joined tables in this piece of code.

Problems after iOS 6.0 update with iMessage and FaceTime

After iOS 6.0 update i had problems to used iMessage and FaceTime

Messages will almost send but stop right before completion. FaceTime will go through only after multiple attempts. After that iMessage will work for a little while. Have talked with folks at apple support but they did not have a solution. Have tried both closing out the programs as well as turning the iPod off and back on. Neither has solved the problem. Any suggestions would be great! Thanks for your help.

Update with use of subquery

I'd like to update all the rows with values getting from subquery from the same table.
For example, the subquery of
select id, some_manipulation as value from table_a
id value
1 12
2 14
3 16
4 21
I'd like to use above info update the values of a column (column2 of table_a) according to the same id. Something like this
update table_a a
set a.column2 = b.value
where a.id =
(select b.id from table_a b);
I know above sql sytax is invalid, but I just want to give you an idea what I'm tryig to accomplish. Any idea?
Thanks in advance,
Ittichai

A slightly modified version of Sri's solution will work for all cases. Assuming proper indexing, this should be relatively fast.

System Update with T440s and Windows 8.1

I installed clean install windows 8.1 (iso directly from Microsoft) and I was thinking, that Lenovo System Update will install all necessary drivers and tools for me.
Sadly, this was not happening at all. Majority of drivers was missing. Even newest bios wasn't offered for install. However, on lenovo's website all drivers was available.
Is this only problem with my laptop or it is general behavior?
Thanks,
Solved!
Go to Solution.

We are way behind in posting Win8.1 drivers/software to TVSU. All I can say is to get the things you need from the website, or else wait another month or so. Sorry for this inconvenience.

My auru script to show all available updates with versions and install

So, I decided to hack together a little script that might be useful to someone else too. I wanted to script that would show me all available updates, from from the official repos as well as from the aur. I also wanted to see at a glance what the installed versions of each package and the new version to be installed are.
The output looks something like this:
[shaun@shaun-asus-x202e ~]$ auru
Available updates from core:
vlc 2.1.2-2 2.1.2-3
Available updates from AUR:
ansible 1.4.3-1 1.4.4-1
Would you like to install all updates without further prompting?
y/n->
Here's the code that I put into a dropbox shared file called arch_functions and source it from ~/.bashrc. Replace the test_apacman function and associated commands with aur wrapper of choice. Once this is in place, I simply run auru once a day on all my machines and I get all the information I need, and only press a y or n in order install all updates.

For someone with a username like yours I would have expected better. I guess you are not a "tech guy" at all. After a while Apple improves the hardware, and updates iOS to take advantage of the features and speed of the newer hardware. Older devices are simply incapable of taking advantage of the newer features, because the hardware doesn't support it. There's a lot of advice posted in the forum from people who warn that you shouldn't upgrade an iPhone 4S to iOS 8, because it kills the performance. If that's true, imagine how iOS 8 must perform on an iPhone 4.
By your reasoning I should be able to run Windows 10 on a 1985 IBM PC. The only reason you can't is because Microsoft had a deal with hardware manufacturers to force people to get new computers.
Or are you arguing that Apple should never improve hardware, because it will leave users of older phones in the lurch?

With all the updates with Firefox and Yahoo, My Yahoo homepage no longer works or functions at all. It doe's work on Safari. When I click on anything on My homepage all I get is a message" sorry bad request".

I also often have to do a forced quit as firefox freezes up. I did not have these problems until I tryed to upgrade to firefox4. for Mac.
I tryed re-enstalling 3.5 but ended up with 5 which was worse. It appears that Firefox and Yahoo are no longer compatible.

I know you can't help with my Yahoo problem, however, apparently at some time in the past I have went to the Sync and tried to figure it out on both my laptop and my desktop, because I have the long snyc key information. However, when I go to try to sync both computers I never get the box to enter that key on either one. That is my problem. So should I try and get a new sync key and see if that works.

Update with exists and subquery
