• How to find the names of tables that have more than 100 columns

  Hi gurus,
  
  Please help me find the names of the tables that have more than 100 columns in the database.

  Below will be useful for you.

  SELECT atc.OWNER,atc.TABLE_NAME,count(*)
  FROM all_tab_columns atc
  GROUP BY  atc.OWNER,atc.TABLE_NAME
  HAVING count(atc.COLUMN_NAME) > 100
  

  Adding another point, you can use user_tab_columns, all_tab_columns, dba_tab_columns, based on your needs/access.

  Thank you

  Based on your last post that only good data must match exactly and your definition of junk:

  WHERE (decode (substr (A.col5, 1, 1), ' ~ ', 'junk mail', null, 'null', 12/31/9999 ', "junk," A.col5 ") = decode (substr (B.col5, 1, 1), ' ~ ', 'junk mail', null, 'null', 12/31/9999 ',"junk", B.col5"))

  AND (decode (substr (A.col6, 1, 1), ' ~ ', 'junk mail', null, 'null', 12/31/9999 ', "junk," A.col6 ") = decode (substr (B.col6, 1, 1), ' ~ ', 'junk mail', null, 'null', 12/31/9999 ',"junk", B.col6"))

  And so on for the six columns.  This assumes that this junk * still * starts with a ~.  In addition, it assumes that the unnecessary and null words are not in the form of good data.

• Find tables that added or remove column

  I use Oracle 11.2.0.2
  
  I want to write a query that lists of paintings who added or dropped columns in a special day say today?
  
  Your help is appreciated.
  
  I need this list of tables because the materialized view build base on these tables becomes invalid when the source tables is changed. In my environment where there are several tables in the source that is constantly changing, it is a hassle to recreate materialized view. Is there an easier way to keep materializing views which source schema changes?

  >

  >
  It depends on the type of schema change AND the type of materialized view.

  There is no other choice but to invalidate the application of MV if a column is deleted which is used in a MV.

  You should always have access to the data in the MV - do you? You just won't be able to refresh the MV because the underlying query uses a column that no longer exists.

  If a column is added, or a deleted column is not used in the MV, then most MVs should not affect. New columns not could possibly have served in the underlying query of the MV and drop columns that were not in the query of MV will not affect the query either.

  As Justin says the AUDITING feature may be your best option to detect these changes.

  Which still prevent the improved varieties to be invalidated and if you have a fast ON COMMIT refresh MV it will fail as soon as the DDL change is made if the table is checked or not.

• Two tables that have a relationship as "many-to-many" and "one-to-many.

  I have the next two represents tables users and the other represents the items where each item can have an author (user) and of course, users can create a lot of articles, so the one-to-many relationship: -.
  
  1. users: -.
  User_id (primary_key)
  User_name
  User_sex
  user_address
  
  2.ARTICILES: -.
  Article_id
  Text
  Author_id (foreign key to the users.user_id)
  
  but the problem I have been facing is that, on another requirement each items can have several (users) approval before being published, so in this way have become the many-to-many relationship, so I created a third table called "trusts": -.
  
  3.approval: -.
  approval_id (foreign key to the users.user_id)
  article_id (foreign key to the articles.article_id)
  level.
  
  so is this a good approach to flow, or there is another way I can better build these tables.

  Hello
  Relationship seems to be ok for your current condition. but make sure you have sequence approval on your table to the approval, in case you should find the flow of approvals.

• Create table with overlapping parallel dates in individual columns

  I try to combine data from two different tables into a single table.

  The data in table 1 contains locations of patients in a hospital where each record represents a single location. Patients can be transferred several times between the different beds resulting from multiple records for a single visit.

  The data in table 2 contains the operative activity of the patient to the Hospital where each record represents either the GOLD of the suspension of the recovery room. A patient may have multiple operations in a single visit.

  I would like to join/merge/mashup data in a single table that contains the data parallel to each other. In other words, dates of the appliance on one side of the table and the activity of GOLD on the other. The difficulty is that the two sets of overlapping of dates of arrival and departure. I wish that the final table to divide the originals in new records when the overlaps do not coincide.

  Example:

  Original in both events (one per table)

  > Unit event has - from 14:00 to 18:00

  > OR event B - from 16:00 to 17:00

  Results in 3 documents (in the final)

  > Event 1 - unit from 14:00 to 16:00, null dates GOLD

  > Event 2 - unit from 16:00 to 17:00 OR 16:00 to 17:00

  > Event 3 - unit from 17:00 to 18:00, null dates GOLD

  Of course overlap can be more complex than the example above and adding code to indicate the 'ghosts' transfers to as well.

  In the code below, the first visit of the GOLD occurs during the first mention of the unit.

  You can use the query above to CREATE or a CREATE TABLE... AS command.

  If you have as much data as you say, a table or materialized view would be maybe faster to use.

  You will notice that I do understand not all columns; I would like to know if you have a problem, including them.

  I don't know what id role plays in this problem.  It is difficult to say when all rows have the same value.

• How to keep the style of setting shaped tables that you paste IN when copying old pictures?

  Hi all

  I know that CMD-SHIFT-V works perfectly to keep the text styles you paste IN when you copy another block of text that contains different styles, but how do I do the same thing with a TABLE?

  I have paintings from an InDesign document with a set of styles/table cell styles, etc and am copying into another InDesign document where I have tables that have table styles different styles/cell, etc. The only way I can successfully get the information in one table to another is to copy the information from the old table with the old styles and then paste it into an excel worksheet, and then copy the excel worksheet and paste into new tables in the new InDesign document.

  Now, wouldn't that be so bad if I didn't have SO MANY hundreds and hundreds of paintings I was working with! I am currently working on a big catalogue and this workflow is slowing down a lot:)

  Please note that I have deleted all styles (by removing all styles) tables I am pasting FROM, but chose to keep the formatting.

  Once more, I bet that I I will kick myself when I see how the answer is easy!

  Any help would be so appreciated!

  Thank you kindly,

  Christine

  Try converting your old text table (column separator: tab; line separator: paragraph). Copy, select the style of lines and columns you want to paste the text in and paste without formatting in your new table. It may not work if your table is very complicated, but it worked for me on a test very simple.
