• Insert/update the column with the clob data type

  Hi all

  ORCL Version: 11g.

  I have a table with the clob data type.

  Test12

  (col1 clob);

  I'm trying to insert/update to update the column with more than 4000 characters.

  But due to the limitation of tank 4000, I could not Insert/Update.

  Need your help in resolving this issue.

  THX

  Rod.

  The limit of 4000 characters is incorrect.  That pertains only to the varchar2 data type.  A clob can hold more than 4 G.

  Here is an example that shows how to insert it, I found...

  Otherwise, here is a way 'dirty' to do.

  insert into your_table (COLA, COLB)

  values

  (PRIMARY_KEY, PART 1 OF DATA)

  ;

  Update your_table

  Define COLB = COLB | PART 2 OF BIG DATA

  where COLA = PRIMARY_KEY;

  Update your_table

  Define COLB = COLB | PART 3 OF BIG DATA

  where COLA = PRIMARY_KEY;

  .. and so on...

  I don't know that I personally recommend the second style...  But he could do the job.

• A statement UPDATE changes the line if the update changes the column even value?

  HI -.

  I have a main classification and the corresponding audit table. I have a trigger. I created using the suggestion:http://www.runningoracle.com/product_info.php?products_id=211

  Now the problem that I am facing is that: if I run the same query (same value) update on the main table for n times (with the same data)... my audit table is updated with a new record every time. He is not able to determine that the value is the same.

  My goal is to load the audit table data if the value in a cell in the main table is really have changed.

  A statement UPDATE changes the line if the update changes the column even value?

  Best regards

  I have a main Table and the corresponding Audit Table. I have a trigger. I created using the suggestion:http://www.runningoracle.com/product_info.php?products_id=211

  Why?

  You try to resolve what made you what are the PROBLEM that select as the solution?

  Now the problem that I am facing is that: if I run the same query (same value) update on the main table for n times (with the same data)... my audit table is updated with a new record every time.

  Yes - it is EXACTLY what you say that you wanted to do and EXACTLY what the code does in this article.

  He is not able to determine that the value is the same.

  I think you mean that the code does NOT check if the value is the same. You can certainly change the code to do this check. But I have a question to start with your need for such a solution.

  My goal is to load the audit table data if the value in a cell in the main table is really have changed.

  OK - then modify the code to check EACH COLUMN and compare its NEW value to the OLD value and insert only the table of audit if SOME (or columns you care specifically) have changed.

  A statement UPDATE changes the line if the update changes the column even value?

  It depends on what you mean by 'change the line '. Of course to update a column with the SAME value does not change the resulting data value.

  But the physical structure of the line, the location of the pieces of line and information in the header block (YVERT, etc.) will change. And, as others have said Oracle doesn't know and doesn't care, so if the new value of a column is the same as the old value will create redo, undo and the rest.

  Start over and tell us what PROBLEM you're trying to solve. Then we can help you find the best way to solve it.

• My date and time settings are set in Egypt and whenever updates of the laptop with microsoft server time, it increases of 1 h.

  My date and time settings are set in Egypt and whenever updates of the laptop with microsoft server time, it increases of 1 h.
  Recently in Egypt, changes of daylight has been cancelled and I guess that's the cause of the problem!
  Any ideas?

  If time was recently cancelled, you can go to your control panel:
  Panel-> data and time-zone (tab) >
  and uncheck the "automatically adjust clock for daylight saving time.

  Otherwise, you probably need to adjust your zone settings on your computer using Microsoft time zone Editor.

• Try to download an update of the firmware with a file extension ROM Vista says it's an unrecognized file type

  Title: download original ROM files on Vista

  Try to download an update of the firmware with a file extension ROM Vista says it's an unrecognized file type. Patches?

  You must get the update of the firmware that can handle the type of file the same place ROMA, you got the firmware file.  From what I see, they seem specific to the product updated. http://www.FileInfo.com/extension/ROM if they don't have it, talk to their technical support staff and ask them what type of program is required to install the firmware provided in ROM format and where you can get it.  Vista doesn't have the ability to read a file ROM type  Some software must be added to give this capability.

  Here is an article I read: "various hardware upgrades and emulators use the ROM file extension." A user needs a flash program usually available on the website of the manufacturer of the motherboard. The user must not flashing BIOS unless the user knows that he has the image of his mother. An error or the computer may be turned off when the wrong BIOS image is flashed. "So be very careful here, or you can completely disable your system.

  I hope this helps.

  Good luck!

• update of NULL in the column with the values of the adjacent column

  Examples of data

  with test_data as
  (select 1 as one, null as two, 2 as three,5 as four, 6 as five, null as six from dual
  union all
  select 1 as one, null as two, 2 as three,5 as four, 6 as five, null as six from dual)
  select * from test_data;
  

  This is one of those cases, the case may be where any value of a column can be null

  or two similar columns can be null. If the column is null then I want to update the adjacent column

  average value of the column, if the first column is null so I want to take the next non-null column and update, if the last column is null

  so I want to take prev not zero column and to update.

  In this case would be my expected output

  Un	Two	Three	Four	Five	Six
  1	1.5	2	5	6	6
  1	2	3	5	6	6

• Update updated the columns with null are excluded from the DB adapter

  Hi all

  My fusion system interacts with DB2 using the DB adapter.

  I have a script that I need to update a flag in the table after completing my bpel workflow. But by updating the value of indicator to "Processsed", there are other columns with a NULL value.

  How to solve this problem. I don't want to do, the other columns should not be alerted.

  Thank you

  Richa

  Hello

  The issue has been resolved. In fact, I've updated the update statement, excluding items that couldnot be updated top link mappings. I had to create a new adapter and it worked.

  Concerning

• Return only the columns with different values.

  Hi all
  
  I am trying to solve a seemingly trivial problem but can't seem to get any clear answer anywhere in any forum. Consider a single table with 5 columns and only two lines:
  

  row_id           first_name         last_name        age            gender
  1                    John                  doe               27             M
  1                    Jane                  doe               27              F  

  Assume that there is no primary key or any other constraint. Also assume that there are only and only two lines of this table. So I need basically a query that, overall above lines, would return first name and sex, because they are only different columns in two lines, as well as their values. Even if I can get sort of column names that are different and that would be enough that I can easily access the values later. It is also important to remember that I may not know the names of the columns in the columns, so basically, somehow, I use user_tab_columns in the process.
  
  Any help appreciated.

  The exact release could be just a varchar variable that lists all the columns that have different values with each column name separated by commas. We'll call the query you want as a QUERY. So, if I do something like

  In this case:

  Output:

  DIFFERENT_COLUMNS
  ---------------------------------------

  This assumes that you have really a table, then you can use ROWID to distinguish the lines, since there is no primary key.
  If this isn't the case, you first assign ROW_NUMBER in a subquery.

• So I think that I can not decrease the scale of the column with an alter statement

  Just learned this, kind of interesting for me. If the column contains data I can increase the scale, but I can't then decreased to its original scale, even if the numbers would be fit. Also from what I've read the only case to reduce a scale is to null, remove, or perhaps copy the column in a column being added.

  Just think it's kinda weird that you cannot reduce a number column, even if the values would be fit.

  This has something to do with the zero no significant?

  Non - Oracle stores ONLY significant digits - not leading or zeros to the right.

• How can I replace the value of the column with a particular value in SQL

  Hi Claude,.

  I guess this CASE clause can be simulated by a DECODE and also it is very easy to use.
  See - http://www.techonthenet.com/oracle/functions/decode.php

  select decode(t1.state,t2.state_id,t2.state_name), t1.count_id
  from  t2, (select state,count(id) count_id
   from 
   where composite_dn= 
  group by state) t1
  where t1.state = t2.state_id;
