• Cannot rename a column in the presentation layer 11.1.1.9

  Hello world

  I'm having a time difficult trying to rename a column in the presentation to 11.1.1.9 layer - even if I uncheck 'use the logical name Colmn' the "name" box does not become white, it remains grey. Am I missing something simple? I thought I could rename objects in the presentation layer to make them more user-friendly for some reason any?

• Warning message before you rename a column

  Hi gurus,

  I need your suggestion. I am desiging a module to move data from one table to the schema of intermediate archives and then delete intermediate tables, such as each table has it's own rules to keep history (some of them need 2 weeks, 1 month etc) and deleting based on reporting_date for some tables, rpt_dt other reporting_dt other and so on... (inconsistent naming). Because most of the tables is not partitioned, I have to do in the conventional way of copying the data and then remove. (Speaking of ~ 100 tables, data to remove from 100K to 1 million)

  My plan is to create a table as follows, which highlights each table name and field based on which remove will

  Table of correspondence:

  KEY	SOURCE_TABLE	FIELDNAME	STARTEGYKEY
  1000	T1	REPORTING_DATE	1
  2000	T2	RPT_DT	1
  3000	T3	RPT_DT	2

  Strategy table:

  STRATEGYKEY	STG_KEEP_DAYS	COMMENTS
  1	14	Default option
  2	30	Keep the last 30 days

  My question is I want to create an alert so that if a developer RENAMES the RPT_DT of the RPTDT column in table T2, it must either refuse the user until it changes the above new domain name mapping table entry. Otherwise refuse, at least draw the attention of the user. How do I get it? I was curious to know if there are new techniques in versions of oracle 10 g / 11 g (mine is 11 g) apart from old techniques I could think

  (1) create a level trigger statement for 100 + tables on the field of Reporting_dt/Reporting_date/RPT_Dt, such that the error is thrown in the exception block (this could slow down the load ETL). Difficult to maintain.

  (2) handle reactive IE perform a daily check to see if a field name in the mapping table exists in all_tables.

  I learned a lot of new techniques in this forum where many new features have been introduced by oracle, or others had a cleaner and better how to implement their experience practice.

  Thank you

  I do not understand how your statement-level trigger approach would work.  Rename a column is DOF, no DML, the ALTER TABLE that rename the column don't trigger a DML trigger.  Level trigger statement that try to validate the structure of the table to the data you're now would place a huge burden and would not raise an error up to this than potentially long after that the disturbing change has been made.

  I guess you can create a DDL trigger that took place when a user has changed the table who tried to validate the DDL against the data in the table (probably using ora_is_alter_column and ora_is_drop_column functions).  That could probably be put into work, but you should always remember to change the data in your table and then run DDL on your table, and not the reverse.

  A DML trigger on your mapping table that checks if the data in your mapping table corresponding to the table definition would be easier to write.  But you would be once again be capture potentially long errors after a rogue DDL statement was executed.

  You could get even more esoteric using something like water course to post the DDL changes and write a subscriber process may change your mapping table or triggered some kind of alert if there was a disconnect.  If you are the Subscriber for a little delay, you could give time for the LMD to the mapping table (most likely) would have completed to make coherent whole before validating the DDL.

  If you are looking for a technical solution, however, I will do as you no matter what time you want to make sure that coherent sets of changes are made - would create a stored procedure that combines some DOF and you want to allow and prevent people from having the possibility to issue direct DDL statements of the DML changes.  If your procedure is written correctly and is the only way to do this kind of manipulation, you should be able to track changes in sync (except for cases where the procedure was partially successful because engages in the DDL and mistakes elsewhere).

  In reality, however, this is not a technical problem if you probably don't want a technical solution.  Rename a column isn't something that would be never done willy nilly.  This is something that should be done as part of a change of control.  This change of control should be considered at least two beings who can catch stupid things.  That change control should be accompanied by tests that validate things like the ability of your process to ETL, data in the mapping table corresponds to the definition tables.  This change of control should be tested in environments below.  At the time wherever a change is ready to be deployed to production, you should be fairly confident roughly that the definition of the table will match the data in your mapping table.  A process-based solution would make me much more comfortable than a technical solution to this kind of question.

• Hundreds of rename logical columns

  Hello!

  I am new to OBIEE and I could not find a solution on google, so I hope you could help us. I have so few physical tables with many columns I want to rename it, but Assistant rename is not an option for me. Most of the names of columns are as assistant to rename and "BF5648" who is unable to transform into a human-readable text.

  So I, in Excel, all the names of physical column and alongside the description I want to use in the business layer and presentation. Can I create a kind of script or I don't know, something I would say OBIEE bulk rename a column with this description.

  If I have to do it manually, it would be a huge waste of time to rename every single logical column one by one.

  I really hope that there is some sort of solution to this!

  I think I have an idea, as we tried to export of AWM to OBIEE and it creates a file of text which I think I can examine and recreate one for my needs, or something like that and I hope it works. It seems to me that a lot of code, but if there is no other way, so be.

• I need to rename a column for a tabular presentation

  How to rename a column, I created for a tabular presentation?

  I added a new column to a tabular presentation (using 'add a new link in the column') and he gave me a name of column, called "link column. I tried to change, but it does not - note: I can't change a sql column does not exist outside Apex - I created it for the display of a calculation.

  I don't know that it can be done as I did before.

  change the column name

  Does not change the name of so cannot reference in my calculation

  Well, I found a way to do it anyway. This should be changed in the definition of region > source.

• Rename the column name of the view

  Suppose I have an employee of the table with the column name. Now, I want to make a view of the employee to the table with the name of the First_name and Last_name column. Is this possible?

  You can also use aliases in the view definition:

  CREATE VIEW employee_view (
    first_name,
    last_name
  ) AS
    SELECT first,
           last
    FROM   employee;
  

  However, you can rename a column in a view. You would have to DROP and CREATE or to CREATE or REPLACE.

  you want to rename the columns during the term of execution of query or in the table itself?

  in the case of then run time query:

  Select empname as employeename, empno as employeenum of the employee;

  If you want to rename the columns in the table itself then:

  ALTER table employees rename column empno to employeenum;

  Hi all
  
  I am creating guests to filter a report on employment applications, and would rename the column (label) that describes the prompt.

  How can I achieve this?

  Of guest are what kind you referring? Prompt dashboard? This is the area of the label. Prompt Filter column? That's the legend.

  Does that answer your question? If this isn't the case, be more specific, please.

• Referring to created columns

  Hi all

  I am a trainee comes to be introduced to OBIEE and the knowledge that you can share with me would be much appreciated!

  In Oracle BI answers, I created two columns using case statements. These columns return the value of ' 0 'or a ' 1'. I would like to create another line which divides the results of these two columns.

  However, since I myself have created and renamed these columns, I can't reference it in another formula of column in the "typical" report "" Format of variables. Is there a way that I'm able to reference these columns? Or is it possible that I am able to use an arithmetic function to divide the results of two case statements?

  Thanks for any help you can offer!

  -Mark

  Hi Mark,

  Welcome to the world of OBIEE

  You cannot reference your owner created columns (Forms) by a name or a variable, OBIEE means in this case is to use the complete formula again.

  In your column formula window, you have a drop down showing you the columns existing in your analysis, if you select one of your 2 columns, you will see that OBIEE does not insert a reference (name) of your column in the formula, but it will again insert the complete formula.

  It of the way it works, so if you change the formula in one of your columns 2 you must also, by yourself, update the formula in the 3rd column with the division.

• [SQL * Loader] ORA-01747 on column name 'INDEX '.

  Hello

  I use SQL * Loader to load the test data for the CSV files. I have a column whose name is "INDEX". SQL * Loader works very well under Linux (Red Hat 6 - Client Oracle 11.2.0.1.0) but I encounter ORA-01747 launch my Workstation Windows (Oracle Server 11.2.0.1.0).

  For more information, I target the same instance (Red Hat 6 - Oracle Server 11.2.0.1.0).

  You have an idea how to solve the problem (without renaming the column )?

  Thanks for any help you can provide.

  I finally find the solution surrounding the column name with double quotes ("") within the control file. Thank you to remember the format of "protector".

• Name of the table mistakenly renamed

  Hello
  
  I've migrated a MySQL existing database to the oracle database.
  MySQL database had a few tables and columns with length > 30, as oracle does not support the length > 30 so it automatically renamed length 30 characters by removing the last characters who are after 30 characters, but today, I found a column of names that are renamed as
  

  All following columns are in single table only
  
  surgey_pa_premedication_detail_dosa renamed to SURGEY_PA_PREMEDICATION_DETAIL (which is quiet right) 
  But
  surgey_pa_premedication_detail_id renamed to SURGEY_PA_PREMEDICATION_DE_730
  surgey_pa_premedication_detail_route renamed to SURGEY_PA_PREMEDICATION_DE_731
  surgey_pa_premedication_detail_type renamed to SURGEY_PA_PREMEDICATION_DE_732

  Thanx

  Oracle was smarter than you think.

  Could not truncate all the columns to 30characters because the first 30characters of each column are exactly the same. Truncation to 30characters would result in the same column name repeats another three times.

  Thus, he executed the only for the first coumn truncate. For the following columns, he 26characters are truncated and added strings of 4 distinct characters.

  You will need to rename the columns yourself to more meaningful names.

  Hello

  I suspect some other developers might have renamed this column and saved as 'System wide default' parameter.

  I hope this helps.
