Alternate merge update

Hello

I have 2 tables with 300 million documents each

Table_A          Table_B
ID                  ID
a_birthYear       Year
b_Birthyear
c_Birthyear

I need to update the year in table B based on the ID in table A (Table_A.ID = Table_B.ID)

The tables have Dups, even if I use separate in update merge... its does not work

SELECT DISTINCT ID,  COALESCE (a_birthYear, b_BirthYear, c_birthYear) Year
FROM table_A;

Update table_B set year = table_b.year 
where Id = table_b.id

So, I wrote small anonymous block using the cursor.

I heard that the rowid-based update is very fast as usual.

Can someone help me please... What is the best way (the fastest way) to update of the year at Table_B which reocrds 300 million.

The two tables has double function ID.

It comes back again to my question:

(c) If you have duplicates (same ID) on Table_A and/or Table_B how do you want the update to occur?

to which you have not responded.

Don't forget that other can help you if you, at least, have an idea of what you want to do.

If we don't let me show you an example:

Table_A
        ID A_BIRTHYEAR B_BIRTHYEAR C_BIRTHYEAR
---------- ----------- ----------- -----------
         1        2005        2007        2008
         1        2010
         1                    2011        2012
         2        2004                    2012
         2        2005
         2                                2008
         3        2003        2011
         3                    2011        2012

Table_B
        ID       YEAR
---------- ----------
         1       2009
         1       2010
         2       2009
         2       2011
         3       2010

How do you update the year Table_B column?
In your original query you use COALESCE to find the first value non-NULL. But how do you want to update in the event of duplicates in Table_A?

Try to explain what you expect with this case.

Kind regards.

Merger Update causes Outlook 2010 Crash

I am beyond frustrated. I've just updated merger yesterday to 5.0.3 and now I can't use Outlook so I'm actually out of business since I manage all my customer communications in Outlook. I need to uninstall the update. Can someone help me understand how to do this?
I am running Windows 7 64-Bit with Outlook 2010. Everything was great before the update.

Yes,

Download the version of VMware fusion, you were using before - from your account, it should show your available downloads.

Stop Microsoft Windows in your Virtual Machine, then quit VMware Fusion.

Open Finder, click go > Applications in the menu, drag VMware fusion to the trash to uninstall VMware.

Re-install the version you just downloaded by clicking twice.

Hope that helps...

MERGER update: is the part WHERE the necessary in part updated?

Look at the example of MERGE statement below, there the line with "WHERE Dt.Column1 = Phpparameters.Parameter1":

MERGE INTO Destiantiontable Dt
USING (SELECT Parameter1, Parameter2 FROM Dual) Phpparameters
ON (Dt.Column1 = Phpparameters.Parameter1)
WHEN MATCHED THEN
  UPDATE
  SET Dt.Column2 = p.Parameter2
  WHERE Dt.Column1 = Phpparameters.Parameter1
WHEN NOT MATCHED THEN
  INSERT
    (Dt.Column1, Dt.Column2)
  VALUES
    (Dt_Seq.Nextval, Phpparameters.Parameter2);

The conduct is necessary or not?
I understand that the line is not necessary, but it may be, can you explain?

Oracle 10g, Linux.

The statement is built in Php code, and the input parameters are: "parameter1, parameter 2. The application must insert or update the Destiantiontable table.

Maybe this line makes it more quick update?

Why Adobe Muse is stuck while trying to merge changes made in the browser edition?

My client contacted me this morning to let me know that one of his pages on its website was down and that it is urgent that it gets fixed. I immediately tried to open the Muse to merge the changes and re - upload the files. I did not work. Muse is stuck in the fusion of customer changes made in the browser edition. So, I called Adobe and have just spent two hours on the phone with a representative of Adobe Muse trying to solve the problem. It reaches point merger/day 2/3 of the files then crashes. The representative asked me to update to Muse that I did and again tried to merge the changes, and it did not work. Then, the representative asked me to change the Preferences of Muse folder in the library of 'old' then I was instructed to uninstall Muse and re - install on my computer. I did it. It still does not. Then the representative asked me to create a new user on my computer. What? Which makes no sense at all. When I asked to speak to the level 3 technical support, I was told that no one was available, but that she would have a supervisor call me back in a few minutes. I'm still waiting for a callback.
For my client's site is not down, I decided with the permission of my client to not merge the changes she made and simply re - download the file I recorded previously.
Can you get it someone please let me know how to solve the problem with ability to Muse to merge updates so that the next time this happens, I'm not wasting two hours on the phone and still not return the right answer or a call from Adobe? Gets a little frustrated by the lack of product support. Thank you.

Hello Andrea,

First of all, I apologize for bad support experience you had. I forwarded this thread on the support Manager to take a look.

It sounds like you hit a bug we have heard reports of the but have not yet isolated, when merging text. There are probably setting a text which, when trying to merge, plant Muse. Until fix us the bug, the best work around is to find this block of text (usually by clicking on merge on each change until it crashes in the Muse, sorry), restart Muse and then jump merger than one change. Afterwords, re-do the changes as part of this text by hand. I know this isn't a great work autour, but it should at least get you operational return.

Best,

Sam

Of course, it's slow.

This is the perfect example of HOW not in PL/SQL code.

Cursor fetch in PL/SQL loops are wrong 99% of the time. When you want to process the data in the database? Use SQL statements. Use SQL statements. And use SQL statements.

No PL/SQL.

Use INSERT... SELECT, MERGE, UPDATE (SELECT) and other SQL constructions.

When you want to change it manually (where you manage the treatment), run this SQL via DBMS_PARALLEL_EXECUTE.

How to create the map that updates only the changed lines
Hello

I have a map that made a merger (update/insert) in a table. The problem is that it will always update all rows in this table. I want to update only the changed lines.

Some dummy code that shows what I want to do.
Current situation (all lines updated):

FUSION
IN
Table 1-t1
USING
(select key_column, Column1, Column2 from table2) t2
ON)
T1.key_column = t2.key_kolumn
)

WHEN MATCHED THEN
UPDATE
SET
T1. Column1 = t2.column1
T1. Column2 = t2.column2
WHEN NOT MATCHED THEN
INSERT
(t1.key_column, t1.column1, t1.column2)
VALUES
(t2.key_column, t2.column1, t2.column2);

What I'm trying to get (only changed the lines updated):
FUSION
IN
Table 1-t1
USING
(select key_column, Column1, Column2 from table2) t2
ON)
T1.key_column = t2.key_kolumn
)

WHEN MATCHED THEN
UPDATE
SET
T1. Column1 = t2.column1
T1. Column2 = t2.column2
* WHERE
T1. Column1! = t2.column1
or t1.column2! = t2.column2*
WHEN NOT MATCHED THEN
INSERT
(t1.key_column, t1.column1, t1.column2)
VALUES
(t2.key_column, t2.column1, t2.column2);

WHERE in WHEN MATCHED t clause is that I'm not able to create via OWB in the mapping. How is that possible?
I tried to look for the solution here and google without success

Thank you!
Hello

you left outer join table2, with table1. Then use a filter to determine which rows in which an attribute has changed or no towing in table1 where found.
To compare attributes use expression with nvl to properly handle nulls: nvl(table2.my_attribute,'#')! = nvl(table1.my_attribute,'#')

Kind regards

Problem in the Merge statement
Hi all

I use the merge updated statement 30000 records of tables having 55 records of Lakes.
But it takes a lot of time as I kill the session after 12 hours, as it was still ongoing.

So, the same day I m using cursors, it will end in less than 3 hours.

I used merge is: -.

MERGE IN Table1 a
USING (SELECT MAX (TO_DATE (TO_CHAR (contact_date, "dd/mm/yyyy")
|| contact_time,
"jj/mm/aaaa HH24:Mi:SS".
)
) m_condate,.
appl_id
FROM Table2 b,.
(SELECT DISTINCT acc_no acc_no
IN table 3, Table1
WHERE acc_no = appl_id AND delinquent_flag = 'Y '.
AND financier_id = 'NEWACLOS') d
WHERE d.acc_no = b.appl_id
AND (contacted_by IS NOT NULL
OR followup_branch_code IS NOT NULL
)
GROUP BY appl_id) c
WE (a.appl_id = c.appl_id AND a.delinquent_flag = 'Y')
WHEN MATCHED THEN
UPDATE
SET last_contact_date = c.m_condate;

In this query, table 1 has 30000 documents and table 2 and table 3 have records 3670955 and 555674 respectively.

Please suggest, what I'm doing wrong with merger, because according to my understanding merge statement is much better than the updates or updates using cursors.

Can be parallelized Alter the dimensions of the column to change tables
Hi all

Can be parallelized Alter tables to the dimensions of the column to change.

I was able to set the explain plan of parallelized command CREATE INDEX and CREATE TABLE STATEMENTS and view the plan of the explain command.
But when I try to apply the market in PARALLEL for an ALTER TABLE to change column size, explain the plan is a failure.

Ex:
EXPLAIN THE PLAN TO ALTER / * + PARALLEL (10) * / EMP_BLKP_1 TABLE MODIFY ENAME VARCHAR2 (40);
ORA-00900: invalid SQL statement

But when I run the alter even outside the plan to explain that it works very well. But I don't know if parallelism is applied for that change the order.

Receive your answer.

Thank you

The PARALLEL indicator tells the optimizer to use the specified number of concurrent servers for parallel operation. The indication applies to SELECT it, INSERT, MERGE, update, and DELETE portions of a declaration, as well as for the table scan part. If no parallel restriction is violated, the flag is ignored.

Windows Easy Install in Fusion 3.1 - does not work with images of XPSP2, only XPSP3?

I am sure that that used to work before merge update itself, so I guess that's 3.1 who broke this - how can I install easy to work with images of XPSP2? My foreign XP images are a mixture of XPSP2 and XPSP3 - I managed to create the two guys before, but now, Easy Install only works with images XPSP3.
How can I get the old behaviour back?

You should still be able to make a virtual machine, but not with Easy Install.

Flash game man of snow - moving ojbects possible?

Hello world
Have you ever met Flash games at Christmas time, where kids can build a snowman, by moving the graphics on the screen...
e.g. to move the balls of snow in place, add a carrot for the nose, move the eyes in place etc.
something lke this:
http://www.Flash-game.NET/game/1482/create-a-snowman.html
All the graphic elements are generally in an area of the game, and the children move just in place. These are some Flash games and flash has the ability to do it,
does anyone know if Flash Catalyst is able to do this also?
Thanks for any help anyone!

Hi David,

Currently, drag and drop interactions cannot be created using Flash Catalyst alone. But there are two ways you can use Flash Builder in association with Flash Catalyst to build an app like this:
1. Prototype of the app in the catalyst, then import it in Builder and in are writing code, add the behavior of dragging parts. Disadvantage: you will not be able to open the project in catalyst after edit it in Builder; to make further changes using catalyst, you will need to change the old copy of the project and then use generator to merge updates into the new copy.
2. The next versions of the catalyst and Builder, code name "Panini" and "Burrito", allow you to create a custom in Builder behavior attribute the work to this behavior directly within catalyst (and continue in catalyst for editing afterwards). Early versions overview of these products are currently available if you want to try this.
Hope that helps!

Ask about the SEQUENCE operator
Hi all

I created a map in which I use sequence operator. I'm filling the data of my staging at the final table. I applied a glance upward and expression to avoid duplication of work than my mapping is going to run every day.
My mapping works very well and he has only to insert the data that are new in the contrary case, it will update.
Now, if a new record just so it will be inserted in my table, but the ID value of line (which is generated by sequence) Gets a different value.

For example:

In my final table, there are 10 records.
Then my ID of the line begins to assume 101 and end at 110.
Now after running the map several times, I add a new record to the table, and run again the mapping.
Now for this new record the value of the row id is 134.

So my point is "* there are 111."

So, how can I do this?

In the expression I use condition "NVL(INGRP1.)". LOOK_ID, NEXTVAL)".

Thank you

Suhail

I applied a glance toward the top and expression to avoid duplication

I don't think that it generates a unique fusion of insert/update. In my view, there is an insert to insert and a merger update.

Suhail,
Can U please confirm

Card export to Excel, vbscript column contains an obsolete reference
I have an explicit card that has as its target account A500

This was changed to A500D, which no longer exists.

When I export this map to Excel, while the target column reflects A500, the VBSCRIPT column shows A500D

Where is he getting this value, is this normal and if it allows me to load to the correct target?

I won't be able to try any validation until next week, but wanted to check in advance

Thanks for any help
Hello

The column of VBScript only plays in Between, In, and Like mapping. Are you sure that not looking for a similar rule, only in one of these types to the place? Export to Excel exports the cards (Explicit, Between, in, and Like) for this dimension.

Also, if it's really an "Explicit" card, the only way that a value can be placed in this column is through a poorly configured model. Where someone filled out a wrong model when it was imported... because the 'Explicit' screen in the web-gui does not give you this field as an option to enter a value with.

In any case, the column is not relevant for the explicit mapping, so I don't see the harm in changing the value. Please note that the import of models is not a replacement/merge/update. Mapping, so is the only way to change existing editing via the web-gui, or removal of all import of a new model.

Hope this helps...

Can't access my photos more iPhoto since update to El Captain... pictures don't merge to Photo app, how can I restore them?

Can't access my photos more iPhoto since update to El captain. photos merged to Photo app, how to restore? Another operating system it will correct?

Cannot access my photos iPhoto since update to El captain

To use iPhoto on El Capitan, update iPhoto version 9.6.1.

If you don't have day before the upgrade of the El Capitan, see: user tip Barney: cannot be updated iPhoto because it is not available in the App Store#.

The El Capitan upgrade removes just the iPhoto in the Dock icon. Have you looked into your Applications folder, if iPhoto is still there?

photos merged to Photo app, how to restore? Another operating system it will correct?

You can open the iPhoto library in pictures by dragging the icon in the Dock of Photos in the iPhoto library.

It requires that the library is on a compatible player. The library must be on a local drive mounted, not a NAS, and file system must be in Mac OS extended (journaled). The reader doesn't have to be a Time Machine drive.

What version of iPhoto created your iPhoto library. If the version of iPhoto is iPhoto 7.1.2 or more, you must prepare the iPhoto with iPhoto Library upgrade library. iPhoto 11: on the development of library

MERGEis a deterministic statement. You cannot update the same row in the target table multiple times in the same MERGE statement.
