• 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.

• Do not update the column if the source column is null

  Hi all
  I'm trying to update some columns on the target, I won't update the column if the source is NULL for the column (do not replace the old value if the new value is zero). How can I do this using OWB. I use 11,1 g.
  
  Any help will be greatly appreciated.
  
  Thank you
  Ravi

  There are a few ways to do this:

  First of all, you can add your target to the canvas a second time as a source, an outer join to the source of queries on the same fields that you use in your target match constraint, and then run the new value and the existing value in an expression to generate the control you need and send the existing value if the new value is null.

  Alternatively, you can use a splitter on the lines with a single stream going where your field is null in this case update you the target without updating this field and the other the field update stream. This means that the generated code will now be an update of re-encoding re - query the same sources for the second pass, and that any recovery strategy you are not dependent on each mapping succeeding or failing as a total unit will have to be reconsidered.

  Or, of course, you can just put a trigger on the table to check the: new.value and overwrite it with the: if old.value: new.value is null.

• Best way to update the individual rows of a Table?

  I took a quick glance at a few examples, but did not get a clarification on this.  I am looking to have something close to a listbox control or the table to where I can update just one column of values to line a 1 time per second pace.  I'm looking to display our acquisition of data values in a table or a listbox control.  The single list box seemed to work well for that, but I couldn't use the row headers to list the names of channel beside the channel values.  I thought to link the values of cursor in two areas of list to do this, but did not find any info on it for the single list box.

  I have a few questions:

  (1) I have a 1 d table to where I want to use this data to constantly update the first column (with a multitude of lines) of a table.  I'm looking for the best route to not take too much time for treatment by doing this.

  What is the best way to update the individual rows of a table?   Invoke the node "Value of the cell value"... or is there another method?

  (2) why is that, after each iteration else, row values are deleted?

  Also, for adding additional channels originally arrray... it is better to use the 'Array' subset then the function "Construct the table" or function "Subset of the table" and "insert table"?

  See the attached example.

  Thank you.

  Jeff· Þ· Bohrer says:

  (2) why is that, after each iteration else, row values are deleted?

  Classic race condition.  dump the loop and node-p and just wire the 2D table on the terminal Board. !

  I don't see the race condition.  What I see is the table once the last element has been written for it all run the oil.  I saw looked it with point culminating performance on.

  But I agree entirely with writing to the Terminal.  It is a 1 d array, so you will need to use an array of generation and convert a 2D array in order so that he could write correctly.

• Need to write the cursor to update the column

  Hi all
  
  I want to write a cursor in the CALC_TAX of the PP_TAX of the UPDATE table column

  This is what it would look like for the first two,

  UPDATE pp_tax p
  SET    calc_tax =
           CASE
             WHEN prov_dec_for_tax IN ('AB', 'NT', 'YT', 'NU', 'NV') THEN

               ROUND ( ( (p.actv_amt * 5) / 100), 2) + ROUND ( ( ( (p.actv_amt + ROUND ( ( (p.actv_amt * 5) / 100), 2)) * 8.5) / 100), 2)
           END
  WHERE  prov_dec_for_tax IN ('AB', 'NT', 'YT', 'NU', 'NV', 'QC');
  

  Just add several WHEN clauses and include in the list of in WHERE clause.

• 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

  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.

• Automatically update the column in the table in OBIEE

  Hi people,
  
  I have a requirement to say I need to update a column of table based on a condition, but this update should happen on a daily basis (I mean that it would be held once per day) by checking if all the records in this column meets the condition then update
  
  example:-column = 'pending', then using the "approved". As records of transactions every day in the table lights. OBIEE should check and update the line so the next time it does not show this line as "pending".
  
  I thought of 2 approaches to this
  (1) through the write-back, it is possible to update but manually (the question is it can't be automated or on demand on daily basis and update multiple records on a go)
  (2) write a stored procedure or a function of update, but how can I perform this procedure either regular or run once daily.how to use it?
  
  Any thoughts on the above two points or any method you can think off the coast.
  
  Any help is appreciated!
  
  See you soon,.
  KK

  Murielle,

  This shud be easy...
  -Create a direct database... with the Update statement
  for example: Update table set col = "Approved" where col = 'pending '.
  -Create an ibot using the RFI above and plan on a daily basis.

  This will update the complete table with the new value on a daily basis based on the State
