Concatenate comparing two rows

Hi all

I have 2 columns in my table;

Col1 Col2

A V
A C
B X
C Y
C Z

I want the result form:

Col1 Col2

A V: C
B X
C Y:Z

If the two lines are identical (say A) then values responsive concate in Col2(i.e..) V:C for A)

Thank you

Hi all

I need to compare two rows in the same table, I don't know hoe to do it in pl/sql. Please help me on this.

xya0004 AMA.7 16

in table b is a unique value for each line, I need to compare the price column and see if the first value is less than or greater than the following value and, if there is more to put the corresponding value of br to a variable, and if it is less, put the corresponding value of the br to another variable. I don't know a method to do this, as I'm new to pl/sql. Please help me in this
```
for data in(select tr,br,price, lag(price) over ( order by tr) newcol

Concatenate two rows

Hello
I have a requirement where to check a table with a list of values in reference data.
I get two rows with a column for each output that every time and I need to concatenate the two rows in a field.
Is there any combination/processor that can be used to do this?
I tried concatenate / merge and merge data from processors without success.
Any direction is much appreciated.
Thank you

It is not clear what criteria do you use to determine which records to eat together. The research is not relevant?

If it's all the records that spent searching you need to eat, it's simple, you can just add a grouping key (for example to add string to a value of 1 attribute), and then group and merge, creating a merged with output value ' delimited list by a "which is used to create the string.

BUG? Statement of BRIDGE to compare two tables
Hello

I tried to compare two tables different dbs and remembered a post on applications to Connectin Cross
http://barrymcgillin.blogspot.com/2010/11/cross-connection-queries.html
```
BRIDGE temparb AS "EB05 01"
(SELECT * FROM arb)
(SELECT * FROM temparb 
MINUS 
SELECT * FROM arb
)
UNION ALL
(SELECT * FROM arb
MINUS
SELECT * FROM temparb 
);
```
I expect to get the differences between the ARB table in my current schema and the table alias temparb arb in the other db. Yet it seems that in this case only the table in my current schema is read.

I materialize at the table BRIDGE with
```
BRIDGE temparb AS "EB05 01"
(SELECT * FROM arb)
```
and select the value that I know to be only in the remote schema
```
SELECT id FROM temparb WHERE id = 2562;
SELECT id FROM arb WHERE id = 2562;
```
Both times I get no results. I even tried to use aliases on the table, same result. Tested in EA3 3.0 and 3.1.

Has anyone tried this before?

Concerning
Marcus
Hi Marcus,

Have you tried without the quotes around the name of connection?

I have a named connection
system_local
which I run the following command

drop table testbridge_remote;
drop table testdbrige;
create table testbridge (col1 int);
insert into testbridge values (1);
insert into testbridge values (2);
insert into testbridge values (3);
commit;

I have a named connection
Name of the connection with space
I performed the following in the

drop table testdbrige;
create table testbridge (col1 int);
insert into testbridge values (4);
insert into testbridge values (5);
insert into testbridge values (3);
commit;

Then I can execute the following statement in the connection of system_local/worksheet

BRIDGE testbridge_remote as the name of connection with Space(select * from testbridge)
+ (SELECT * FROM testbridge_remote +)
LESS
SELECT * from testbridge
+)+
UNION ALL
+ (SELECT * FROM testbridge +)
LESS
SELECT * from testbridge_remote
+);+

It works well.
Returns the rows in the remote table not in the local table and lines in the local table, not the remote table.

Kind regards

Problem of VORowImpl - compare two lists of LINE]
Hello world

I have a huge problem right now, I am trying to compare two list VO with the same values, it's because a he tied to an advancedtable the xml page where the user can change some values and the other is the table values, but DB, the reason is in fact a validation to compare the original values from the DB with the tabla list and update only lines that users made changes in their values, here is my code for the better explain what I'm doing:

{} public void saveChanges()
OADBTransactionImpl oadbtransactionimpl = (OADBTransactionImpl) getDBTransaction ();
Row [] rows1 = getAppVO1 () .getAllRowsInRange ();
Row [] rows2 = getDBVO1 () .getAllRowsInRange ();
for (int i = 0; i < rows1.length; i ++) {}
int j = i;

To compare collections
R1: collection of the app
R2: collection of comics
AppVORowImpl r1 = rows1 (AppVORowImpl);
DBVORowImpl r2 = (DBVORowImpl) rows2 [j]; <-here in the second iteration is displayed the following error message:
"oracle.apps.fnd.framework.OAException: java.lang.ArrayIndexOutOfBoundsException: 1.

string variables to check if changes in the column
String columnAPP = r1.getId (m:System.NET.SocketAddress.ToString ());
String columnBD = r2.getId (m:System.NET.SocketAddress.ToString ());

"If" that commits the changes
{if (! columnAPP.Equals (columnBD))}

SP string variable
StringBuilder procedureCall = new StringBuilder();
the call to SP
try {}
procedureCall.append ("... stored proc...");
OracleCallableStatement oraclecallablestatement = (OracleCallableStatement) oadbtransactionimpl.createCallableStatement (procedureCall.toString (),-1);
oraclecallablestatement. Execute();
getOADBTransaction () .commit ();

} catch (SQLException sqlexception) {}
System.Err.println ("SQL Exception:" + sqlexception.getMessage ());
getOADBTransaction () .rollback ();
throw OAException.wrapperException (sqlexception);
} catch (Exception e) {}
System.Err.println ("Exception:" + e.getMessage ());
getOADBTransaction () .rollback ();
throw OAException.wrapperException (e);
}
}

}
}

the first iteration works fine, but the second and the futher shows an exception error, what can I do to make this method work?
I'll be waiting for your answers, I really hope you can help me with this one

Kind regards

Here's the code to dump for you. Code, you should write in AmImpl and the same controller class call.

Code AMImpl
```

        OAViewObject vo = (OAViewObject)getMainViewObjectVO1();
        OAViewObject dvo = (OAViewObject)getDBViewObjectVO1();
       if (vo != null && dvo != null)
         {
                     //1st VO
                       dvo.setWhereClauseParams(null);
                      //Set where clause if Any  dvo.setWhereClauseParam(0,xx);
                      dvo.executeQuery();   

                     //2nd VO
                     vo.setWhereClauseParams(null);
                      //Set where clause if Any  dvo.setWhereClauseParam(0,xx);
                     vo.executeQuery();  

   }
  }

 public void compareViewObject()   // Calling this method to compare Attribute of both View Object *Process Form Request*
  {
      OAViewObject vo = getMainViewObjectVO1();
      OAViewObject OrigVO = getDBViewObjectVO1();

     RowSetIterator originalSelectIter = OrigVO.createRowSetIterator("originalSelectIter");
     RowSetIterator selectIter = vo.createRowSetIterator("selectIter");

     if (fetchedRowCount > 0 && OriginalfetchedRowCount >0)
        {
          selectIter.setRangeStart(0);
          selectIter.setRangeSize(fetchedRowCount);
          originalSelectIter.setRangeStart(0);
          originalSelectIter.setRangeSize(OriginalfetchedRowCount);
          for (int i = 0; i < fetchedRowCount; i++)
          {

            rowi = (MainViewObjectVORowImpl)selectIter.getRowAtRangeIndex(i);
            rowii = (DBViewObjectVORowImpl)originalSelectIter.getRowAtRangeIndex(i);

           //Compare Attribute here

               if((!(rowi.getRoleStartDate().equals(rowii.getRoleStartDate()))

                }

How to compare two lines in PL/SQL?

How to compare two lines in PL/SQL? Is there a method I can use to compare their column by column instead?

Any comments would be much appreciated.

Ah, finally, we get a bit more useful information

and I need to compare the column by column to see if there is a difference between these two rows.

Like this, you mean?

My only concern is the result of this sql. East - reliable? It can really be used to differentiate the two lines? I mean, the result would be the same, as I do with Java?

Not sure what you mean by "reliable"? SQL is not some kind of generator of random result (by derogation from the use of the DBMS_RANDOM package). If you ask him if 1 + 1 = 2, then it will always give you the right answer.

How can I move App Tabs down, where are the other bookmark toolbars? Or, how can I put my toolbars on two rows bookmarks and forget the App Tabs?

I have several bookmarks in my toolbar, and my most often used found in a drop down menu, which is annoying. I have tried to click and drag on the menu bar, there was room for more icons, but they didn't budge. Anything under the "toolbar" has been helpful. Help tell me do right click on my toolbar and then click on 'Customize'... which did not come as an option. I would like to really all my favorites toolbar (I have about 10) or real on the toolbar visible, not hidden in a small dropdown tab menu.
There is a plug-in that allows you to put bookmarks in two rows on your toolbars, but it is not compatible with my version of FF (7.0.1).
App Tabs are cute, but I don't like them on top where they take place where I have the legs for various open websites (I usually opened several at once). App Tabs are fixed and do not move as site tabs, which is extremely annoying and so why I 1) want to move to the bottom of the toolbar or 2) be able to view all my bookmarks toolbars - which is what I prefer.
BTW, I have Windows 7.
Thanks in advance for your help.

App tabs are special tablets and are always displayed at the left end of the tab bar.

You can place all the bookmarks that you want to see the toolbar of bookmarks in the bookmarks toolbar folder.

You can do this in the sidebar or the Manager of bookmarks if you can't do it on the bookmarks toolbar.

Most visited is a special file (smart) which shows the websites that you have visited and are not necessarily Favorites, so you can not drag on the personal bar unless you first to bookmark the. You can make it open in a tab by clicking on Star on location bar twice and choose the toolbar of bookmarks as destination folder.

Is it possible to compare two PDFs using labview?

I was wondering if it was possible to use LabVIEW to compare two PDF files (that contain images as well as text) to another. I know that Bluebeam PDF viewer can do, so I was hoping there was a way to do it with LabVIEW.

Read each file as a simple string, and then compare the two strings for equality.

(You can also do a few tests before, for example just to see if the sizes are equal)
