• Check the values in two columns, in the affirmative, then generate an error

  Oracle 10g version

  Hi gurus

  I'm test1 table and it contains several columns, my requirement I want to create some sort of conditions or constraints before inserting data into test1, it will check that application_id or APPLICATION_TYPE_CD contains no values in the two columns...

  I appreciate your advice. Thank you

  / / DESC test1

  APPLICATION_ID NUMBER (10)

  DATE OF APPLICATION_DT

  APPLICATION_TYPE_CD VARCHAR2 (10)

  DATE OF CREATED_DT

  Concerning

  You need a check as a constraint:

  ALTER table test1 add constraint only_one

  check ((application_id n'est pas null et application_type_cd est null) or)

  (application_id is null and application_type_cd is not null))

• Trigger that fires on the value of a column

  Hello everyone,
  I'm willing to do a trigger working on the column value.
  the requirement is that the column has the date and time I want to automatically update another table on the specified time. like for ex. leaves saying the value of this column is 26 October 2008 21:00 then date and time the trigger triggers, delete this value and update another table.
  so is it not to write something like this, or any other way to do this.
  Thank you
  Rahul

  like for ex. leaves saying the value of this column is 26 October 2008 21:00 then date and time the trigger triggers, delete this value and update another table.

  What you could try is:
  1 create the procedure that makes some logic you want
  2 create a trigger on the table (before integration), in which you can create a task (dbms_job/dbms_scheduler) who perform the previous procedure at the time defined by the value of the column.
  3. a validation will validate your changes of data and validate the creation of jobs, cancel rollback job creation.

  That way, your work (aka trigger) fires exactly at the scheduled time.

• Partial Page rendering - refresh value in the column

  Hi gurus of the OFA.
  I created a page of creation and followed the tutorial on Partital page made by creating a view PVO object and I am able to make the "EmployeeNumber" / "Location" column true false GOLD according to the value of another field (area).
  
  The 'TypeMonitored' (choice of message) has 2 values (area/employee). If the user selects the 'zone' then "EmployeeNumber" column should be hidden and if the user selects 'Employee', then the 'Place' column should be hidden. It works very well.
  
  My problem is if the user has selected 'Employee' in the 'TypeMonitored' of poplist and registered the "EmployeeNumber" and then immediately again if the user selects "Domain" of the "TypeMonitored" of poplist and enters the 'place' (since the site is now visible to the user) and click on Save and then the record is get recorded with the two values. I need to have the value of the column of 'Employee' to be empty in this case.
  
  Basically need to SETTING / erases the value of EmployeeNumber before any record in the database.
  
  Any help would be appreciated to greatlly. Please let me know if you want more details.

• Displaying a string instead of the "null" value in the columns of answers

  Is this kind of possible substitution only in the web interface of answers, or still in BI Admin meta - data? I would be very interested to recognize from analysis UDML in metadata,
  Thanks in advance!

  You must do this in the business model and the Mapping layer

  Go to the properties of the column

  1. in general tab, you have "use existing columns of logic as a source.
  Select this check box. Click the period (...)
  In the formula for the column, you can add the condition of ifnull
  In this col formula editor, you can choose the logical columns.

  2. on the Data Type tab, you have the maps and logical sources
  Here too you can achieve.
  In this col formula editor, you can choose physical columns.
