By comparing the two records and return only the differences
Hi all!Assume the records as follows:
USERID USERNAME STREET CITY PHONE
---------- ---------- -------- ------ -------------
1 John Smith Street 1 City 1
1 John Smith Street 1 City 1 (31) 234-1234
UserID is PK on this table. Imagine that this application represents two versions of the same record on a table. This recording was 'day' and the phone field changed from null to "(31) 234-1234'.»What I´d like to do is to retrieve only (or fields) that changed between these 2 versions of the same record. The idea is to call this query (or process PLSQL) a trigger and save these data on a table. The data returned by the query (or process), on the example above, should be something like:
USERID USERNAME STREET CITY PHONE
---------- -------- ------ ---- -------------
1 (31) 234-1234
1 row selected.
If two columns have been modified, (Eg., City column also changed "City 1' to 'city 12'), the return value should be:USERID USERNAME STREET CITY PHONE
---------- -------- ------ ------ -------------
1 City12 (31) 234-1234
1 row selected.
Any idea?Thank you very much for your attention.
Hello

Looks like you're simply wanting a trigger?
Something like:
CREATE OR REPLACE TRIGGER audit_trg
AFTER UPDATE ON your_table
FOR EACH ROW
BEGIN
INSERT INTO audit_table(userid, username, street, city, phone)
VALUES(
:new.userid,
nullif(:new.username, :old.username),
nullif(:new.street, :old.street),
nullif(:new.city, :old.city),
nullif(:new.phone, :old.phone)
);
END;

How can I compare the differences between two files After Effects?
I have a major problem. I was working on special effects for a film. In After Effects, when I change siggificant, I often have to register under and create a new name so I can go back to the old work if necessary. It comes in a case, I have come back from earlier works. If I use these two files After Effects allows you to create multiple clips of effects. And I do not remember just where you look at it, it is better. Does anyone know a good way to compare the differences between the files?
One thing to keep this conversation on the right way: I know that I did a stupid thing. I've never done this before so can we please not spend a lot of time on how to avoid this problem and stick to how we solve this problem?
If you encounter difficulties to identify differences in the old and new versions, you can use this procedure:
To avoid confusion, I'll call your former company and your most recent compositions CompB comps.
CompA drag "New Comp" icon in the project window. This will create a new temporary layout that contains the nested CompA.
Drag in your new COMP CompB temporary ensure it aligns image for image with CompA.
Place the top layer (CompB) difference.
Now, when you play through the comp, you'll see differences in color at a time where the comparison and CompB are not identical.

If I understand correctly, the joints can not work with CONNECT BY / START WITH queries?
A WITH clause is an option?
If possible, I don't want to put a selection in a database to display object and join against other queries.
Thank you.Hello

If possible, I don't want to put a selection in a database to display object and join against other queries.
Yes, a WITH clause that is an option. Viewed online, as Zhxiang has shown, are another option. Either way gives you a regular display effect without creating a database object.
You did not show a sample and the results, so no one can tell if a join is really what you want. Other possibilities include INTERSECT or an IN subquery.

Incompatibility between the two recorded and stored data
Hi guys, I am preparing Labview codes for reocording synchronized analogy and reading. Specifically, I want to record for 6 seconds, while the sounds of output for 5 seconds. This means that the analogue output stop 1 second before the end of the recording. In addition, I want to save the second 6 check-in 3 files TDMS (2 seconds). However, I couldn't do my codes work in the required way (attached). I have identified two problems that are beyond my skills.
1. "some or all of the requested samples are not yet acquired. It's weird, because I already have the function of "DAQmx Read" provided that only when there is sample to read.
2. instead of save data to 3 TDMS files, only one file is generated.
I am grateful for your help. Thank you very much.

You have a beautiful mess! (Sorry, but you do) Your little logic code.
First of all, if you want to save data to a file aDAQmx TDMS task do it! Enable logging of data it will greatly simplify your diagram to the point where some of the other problems become more obvious.
Now, let us look at this section:
In the present, I can that you used to be a programmer of text. These subsets 'replace Array' actually boggle my mind! Why replace the first element of the tables full of zeros? and why is it a picture of 5,000 items? Looks like you put 5000 zeros on the front and back of the noise AND stuffing a 0.99 in the first element of an array of 5000 zeros only to replace the range of a 0.99 and 4999 zeros with a table of 5000 zeros TWICE! (in case the first subset of the table replace did not work? WWYT?) But save a little... A high pass filter with fh = 11000 and fl = 8000?
Save the help file, we find:
Then, this constant 110000 doing here? (Other than ignored)
Save a little and you father a production 1.25 M points of noise Gaussian with a gap of 0.1, but the constant is labled rms. (Go fix it now before you confuse us no more!)
In all sincerity. I've seen worse but please correct obviously I did notice and we could be much more effective to help with the subtle substance which can always be wrong.

Thanks for the requestThe query does not work with the following documents
insert into test_dep select 16,'AS',750664,'PG',750758 FROM dual insert into test_prs select 4,750758,750668 from dual
the r_id should not be put in correspondence with the columns in the test_dep table. P_id must only be put in correspondence
OK, you want to match against the de_id and the de_u_id p_id? Or a line where either p_id concordances r_id de_u_id or de_id must not be returned?
To match p_id against de_id and de_u_id, you can write the query like this:
select id, p_id, r_id from test_prs where p_id in (select p_id from test_prs minus select de_id from test_dep minus select de_u_id from test_dep);

I get a new hard Hard Drive (SSD). The new disc is the same size as my existing SATA drive. I can do either a new
the installation of Windows 7 or a clone old hard drive? I would prefer to clone the old hard drive and keep all my settings, etc. It's empirical data on the performance difference between a new installation of Windows 7 or to continue with the Windows 7 which was 3 or 4 years ago.
I know the conventional wisdom is that the new installation is faster, but, no matter who actually tested and compared the differences? I know I'll get better performance of the SSD the SATA drive, but I don't know if it's worth the hassle to do a fresh install and redo all my programs and settings.
Others that the performance of the SSD you should not see any differences. If you do, you can always do a clean installation later.

So basically it's a bad situation
How heavy this weighing in a join will select the instruction?
for example, left to join an intermediate table (200,000), with a huge table (40.000.000 rows)
where is equal to staging.varchar indexed field huge varchar field table
AND that calculated the difference > 5?See [when your query takes too Long | http://forums.oracle.com/forums/message.jspa?messageID=1812597#1812597] for what you must post to get advice on the setting.
Are you saying that the part of the join condition which is the date of a table must be at least 5 minutes later at the time of the other table? In other words, you're doing something like:FROM staging s LEFT OUTER JOIN huge_table h ON h.txt = s.txt AND ( TO_DATE (s.utc_date_new, 'YYYYMMDDHH24MISS') - TO_DATE (h.utc_date_old, 'YYYYMMDDHH24MISS') ) * 1440 > 5
If so, try to change the terms of join like this:
FROM staging s LEFT OUTER JOIN huge_table h ON h.txt = s.txt AND h.utc_date_old < s.utc_date_new AND ( TO_DATE (s.utc_date_new, 'YYYYMMDDHH24MISS') - TO_DATE (h.utc_date_old, 'YYYYMMDDHH24MISS') ) > (5 / 1440)
Even if the new condition (the other,
AND h.utc_date_old < s.utc_date_new
are covered by the third condition, it can leave a lot of matches be excluded without a conversion from VARCHAR2 to this DAY.
Also, don't multiply each difference in 1440; Just compare the difference within days to a constant. I don't know if the optimizer is smart enough to do it for you, but why take the risk?would be to limit the calculation to: to_date (to_number (nw.time_utc), \'YYYYMMDDHH24MISS\')
give a significant increase in speed?I think it's the opposite. The first TO_DATE argument must be a string; the above expression is to convert the string to a NUMBER (which takes a while), and while the NUMBER is implicitly converted to a VARCHAR2 (which takes more time).

To begin with, I am the HelpDesk of the company and our users are running Windows 7, Vista and XP. The problem will occur randomly on most XP and Vista systems.
I'm beginning to believe that it is a computer problem to the extent of the material or something of this nature.
For now, I swapped the computer and now the question is not fooled by the user.
But in general I wanted to know why this happens. They will be blocked (not a stop) their computer to take a lunch break and when they return to log in order to return to work. They work on two monitors and for some reason, as the settings go back to the single screen...
Why this keep happening? Help, please?
Either way, I don't think it's a driver problem... Because I just run images on hard drives of all application users run and the problem occurs randomly.
Thanks in advance for your response...

The column that does not match when comparing two records
Hi all
We try to compare two tables and find the differences. So if two records (1 of each table) have same PK but not always matching because of some columns, then we would display this columnname. For example:
Table 1
PK Parent Child Property1 Property2 1 A A1 P1 PR1 2 B B1 P2 oraPR2 3 C C1 P3 SRP Table 2
PK Parent Child Property1 Property2 1 A A1 P1 PR1 2 B B1 P2 PR2 3 C C1 P3 PR4 In the above example when I compare 2 tables all matches except Property2 online n ° 3. Thus, we would like to get an output like:
PK Column_Mismatch 3 Property2 (this must be the name of the column that does not match) Appreciate the help.
Thank you

Why you don't want no matter what exit for pk = 2? Property2 does not correspond either to pk.
What happens if the 2 columns (or more) do not match? The following query would produce a list delimited, such as ' parents; PROPERTY2 '.
WITH got_mismatch AS
(
SELECT pk
, CASE WHEN t1.parent <> t2.parent THEN '; PARENT' END
|| CASE WHEN t1.child <> t2.child THEN '; CHILD ' END
|| CASE WHEN t1.properry1 <> t2.property1 THEN '; PROPERTY1 ' END
|| CASE WHEN t1.properry2 <> t2.property2 THEN '; PROPERTY2 ' END
AS the offset
FROM table_1 t1
JOIN table_2 t2 ON t2.pk = t1.pk
)
SELECT pk
, SUBSTR (incompatibility, 3) AS column_mismatch
OF got_mismatch
WHERE mismatch IS NOT NULL
;
If you would care to post CREATE TABLE and INSERT statements for your sample data, and then I could test this.
The query above does not count NULL values as inadequate. If you want that, the same basic approach will work, but you can use DECODE instead of <> to compare columns.
What happens if a pk exist in a table, but not the other? You want an outer join, where I used an inner join above.
