Bad column update
I'm trying to use SQL Developer (version Version 1.5.0.53) to update a table of metadata.However, when I commit the changes, most of the time (but not always) it updates the wrong column.
either I change the value in column A, but it puts the value in column B. The papers reflect this:
UPDATE 'BLAH '. "" COLUMN_B SET my_table ' = 'New value' WHERE ROWID = 'AAAYGJAAHAAAAgIAAM' AND ORA_ROWSCN = '23746097360'
The reverse happens too (B updates go to A).
I had the same problem on 2 different tables (both with the same structure).
Any ideas on what is causing this and what can I do about it?
If I can't get this sort I have to do updates manually that will take some time and be very tedious.
This can happen when you never to rearrange the columns in the user interface. For updates sqldev think again, they are in the original (due to a bug of long term) position.
Should be set when making preferences - Database - ObjectViewer - clear persisted table...
Also install the new versions (I suggest 1.5.5 last or EA 2.1) or remove the dir parameters would be left to zero defects.
Have fun

How to erase a bad windows update? Is there a Temp file or download that I can remove? I love Windows 7 but I have a window 10 day that I stopped and you want that he erased!
You seem to be on W7 and tries to clear a update that maybe wanted to take you to W10. Your question does not belong to this site, because this site makes testing beta versions of future versions of W10.
However, if you go on the d/l from Microsoft site and search for "wushowhide.diagcab", it is a program that allows you to hide updates. I have used in the past. Let it run for a few moments and it can offer hide this update unnecessary and probably for an offer that is no longer valid.

Rendering fonts were going badly after update 32.0
After the recent update, the police started making bad. Kind of blur with jagged edges and transparent parts. It used to be well D:
Sometimes it is OK for a while I scroll pages, and sometimes when I stop scrolling, the police remains as it is. as if there are specific positions render text correctly. However, not all policies are affected. Those inside the scrollable area.
Times that the police properly, return the bookmarks is, title bar and the tab name is unaffected and appears is not smooth. Same is not the case on other browsers. All my other system fonts look good; It's really just Firefox.
Restart Firefox = failed
Restart computer = failed
Tried the clear type = setting did not work
Tried to activate and disable hardware acceleration on Firefox = failed
Tried the activation and the deactivation of the graphics card itself = failed
Tried pretty much all the advice I found on Google = none worked
Tried the complete uninstall and re - install Firefox 32.0 = did not workGraphics driver is updated.
Windows is updated.I use Windows 7 Ultimate 32 bit
Graphics AMD Radeon HD 6800 cardI fixed it by downgrading to Firefox 31 who assures me that 32.0 is the culprit. As I was about to send the message at the top. I tried without decommissioning as my last resort, and it worked. Now I send you only that in a report. I hope you will understand what caused it because I'm quite strict (OC) that everything in my PC must stay update > _ <. so, I want to use Firefox 32.0 as much as possible.
You can try with the catalyst beta driver of http://support.amd.com/en-us/kb-artic.../latest-catalyst-windows-beta.aspx? 14.4 catalyst has been blocklisted for direct2d because of stability issues in firefox 32 (bug #984488).

Satellite A60-202 after bad BIOS updated the PC does not work
Hello
After a very bad my BIOS update, my PC doesn't work and doesn't turn on.
What to do now?
It is Toshiba Satellite A60-202 with 512 MB of memory and 40 GB of HD.
model PSA60E-OLP06TFR SA60-202Thank you
Yves
HI Yves,
Unfortunately, if the BIOS update procedure does not work (or fill), then it is likely that the BIOS in the CMOS chip had been corrupt and without it, you will not be able to boot your laptop to fix the problem.
It will be necessary to bring (or send) your laptop to a repairer authorized to have reflashed BIOS.
Kind regards

How doI identify the update and remove/replace this update? For most machine works very well in the case otherwise, I ran 'disk health check' and the HD is fine. I switched to Avast A / V AVG 9.0 because wants to make a "business optimization" and never to complete this analysis. Very frustrating to deal with. Someone at - it a similar experience? Help?

Flag value does not change after the SCD TYPE1 column update
Hello
I had scd type3, type2 successfully.
I'm trying to implement the type 1 scd.
For this, I change slow dimension & ckm oracle the oracle select ikm.
the source and target tables are the following. for the type 1 scd, I chose scd behavior as existing lines updated on behalf of the emp, sal columns.
Start timestamp to join date and the current flag to flag column.
first ename is smith when empno is 7369.
I've updated ename
Update scdtype1_source set ENAME = 'AA' where EMPNO = 7369
After running, I don't have to change the flag o to 1 in the target table.
SCD type1 mainly used for replaces old values., but I add flag column in the target table for easy identification. () column in which I updated)
I have not any change in the flag.
Please help me,
Thnaks in advance,
A.Kavya
Hello
I'm not sure what you're trying to do will work. In the case of Type 1 SCD are you still using the dimension of change slow ikm oracle? The flag is updated to 0 in the case of CDs because of the code in step 2 "' Historize old rows where CPCs flag is set to '0'.» In your case, that no new record is added in the case of an update so the IKM does not change the flag.
I'm not sure of your requirement either. You say you want to identify the column in which you have updated. How is an indicator will tell you what the column value has been changed? Maybe you want to know which line you have updated? If this is the case and lets say you set the flag to 1 in case of update what happens when another updated same record?
I would suggest you add an updated time stamp column to your table and set of sysdate but in properties check only the update and will not insert. What that would do is update your record, it will fill the current date and time so that you can identify that this record has been updated.
If you want to always go for the flag, then follow the same approach but in your mapping, change the value of the flag to 1 instead of 0 and new check only the update box (uncheck the box insert). In your create table statement the default value of this option to 0. So when the new line is inserted database is automatically assigned the flag to 0 and where there is an update, ODI it will change to 1.
Thank you

The Master Table column updated based on the sum of column Table detail
With the help of JDev 11.1.1.6.I have a master-detail table based on a link to BC.
The main table has a column that displays an InputText or an OutputText, based on the value in another column.
If the InputText is displayed, the user can enter a value and the database will be updated with that value.
If the OutputText is displayed, it must be a sum of a column in the secondary table. Also, this value will be written in the database.
Question:
How can I fill the OutputText in the main table with the sum of the values in a column in the secondary table?
The detail table column is a manually entered InputText field.
Thank you.
Create a spike in the main table and write in its expression as follows - DetailVoAccessorName.sum ("ColumnName");
This will calculate the sum of column table detail and then you can set the value of the transient attribute to attribute DB on backup operation

Date column updated with trigger update of the geometry
Hello
I have a column named "GEO_MOD_DATE" which is supposed to be updated every time that my geometry column is updated. My trigger code is below. Currently the trigger is fired when other than my column of geometry columns are updated. I searched the forum and many other sites. As far as I know, my trigger is written correctly. But I can't understand why it is taken when the columns except my geometry column are updated. You have any ideas? Thanks in advance! Note that the trigger fires when I update the geometry column. However, it is also SHOOTING when the other columns are updated. I have also tried adding 'OF GDO_GEOMETRY' from "BEFORE UPDATE" paragraph and which did not help.

Yes. But what does this mean for the SDO_GEOMETRY objects is that you cannot directly use a WHEN clause in the definition of the trigger and you cannot compare two geometries directly via If (: old.geom =: new.geom) then.
So, in your trigger update of your business rules conditions require the trigger to implement are not enough.
Try to check if the geometry column has actually changed.

SmartView VBA - can't set "Width of the column updated"
Hi people,
I am updating a series of workbooks based on the API VBA Essbase v9 on SmartView 11.1.2.1 and touched a problem - I am new to VBA SV commands, and I hope that it is something obvious that I'm missing.
One of the functions which is essential to ensure recovery of data does not affect the layout of spreadsheets is the parameter 'Adjust the column widths', which, in the VBA Essbase API, could be managed by using the EssVSetSheetOption function, but neither HypSetGlobalOption nor HypSetSheetOption appear to have such a capability. The only option I have is to run get followed by some reformatting of the column widths, which seems rather ineligant for me.
Any ideas?
Thank you very much
Daveresearch in the .bas file (and what needs to be included in your project that I find HSV_ADJUSTCOLUMNWIDTH in the definitions of the index count options to use for HypGetOption/HypSetOption
Note, I'm looking at the 11.1.2.2 version, your mileage may vary depending on your version
