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

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

• 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.

• How to rename the bookmarks pinned to the taskbar?

  Firefox 18.0

  I have a few bookmarks pinned to the taskbar. They show the URL of the link, not the name of the bookmark. For example; in my menu bookmarks, I have a bookmark named "hotmail", but when I pin in the Firefox icon in the taskbar, it appears as https://login.live.com.

  How to rename or get it to show the same name as the menu drop-down?

  Step 1: Create a bookmark to the URL in firefox with the name you want.
  Step 2: Drag the bookmark on the desktop (it can create it with the IE icon)
  Step 3: Drag the icon to the icon of firefox pinned in the taskbar. This should pin the URL in firefox with the name. It will be useful.

• How to fill a column with numbers and maintain when adding or deleting lines?

  So far, I've discovered two ways to fill a column with the number:

  1. Enter '1' in a single cell, '2' in the one below, select both, and then use the yellow dot to drag down - it will do the rest.

  2 create a formula such as 'A2 + 1' and drag also.

  However, in both cases it will work if I manually this continues to do for each newly added line at the bottom. Now, that alone would not be that big of a problem if it wasn't for the fact that I'm working with a table where the lines can be added among other rows in the future.

  Having said that, could someone please tell me how to create a column with a number that will increase automatically? I mean - if I add a new line between line 56 and 57, I want the new line to have a '57"in it, and the" old 57 "would now be"58"and so on." " I don't want to drag the whole column, which can be hundreds if not more than a thousand lines.

  Try to put this in the cells in the column:

  = ROW()

  In the formula, you can add or subtract a number if necessary to get the starting number that you need.

  How always show left column on the screen, when I scroll to the right of a large spreadsheet

  If the left column is a column header, you can check freeze header columns in the table menu.

  

  Better not to use TOO many columns.  Numbers works best with relatively little.

  How big are your real matrices? How do you measure the speed? How fast is now and how fast should it be?

  In all cases, you can do it with a single loop, for example as an attachment.

• How to rename a file when you move it

  How to rename a file when he tries to move it to another directory and it already exists?
  I thought I could use a match pattern on the paths of the source and destination, because after a certain point, the path would be the same, and then with another model of correspondence I extract only the name and use a path of construction.
  I don't know if it would actually work. Can anyone give me any suggestions?
  Thanks in advance!

  
  

• How to rename channel in VI

  Could someone explain to me in a fundamental way. How to rename channel merged in the attached VI names.

  By default, they read without title, Untitled_1 and so on. I want giving them a logical name as coil Temp, Temp of the battery etc...

  Thank you

  Why put another image when you already have one, a VI, posted in a response.

  If you insist on using to write into the file of measures and insist on having the names of channel, you must use the procedure that I linked to. At least give it a try before posting back.
