  Hi Stacey Nathan,

  To remove the items from right toolbar, click Tools at the top.

  Then open the fall down to the accessibility or analyze and select 'delete the shortcut '.

  In a similar way, select "Add a shortcut" in the Tools drop-down menu to add to the tool on the right pane.

• 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.

  Hi Satya,

  Here's another solution. You can try the formula below as it is:

  Cast (floor (TIMESTAMPDIFF (sql_tsi_second, '-SNP_SESSION '.))) SESS_BEG, '-SNP_SESSION '. SESS_END) / 3600) as char). ':' ||
  Cast (floor (mod (TIMESTAMPDIFF (sql_tsi_second, '-SNP_SESSION '.)))) SESS_BEG, '-SNP_SESSION '. ((SESS_END), 3600) / 60) as char). ':' ||
  Cast (mod (TIMESTAMPDIFF (sql_tsi_second, '-SNP_SESSION '.))) SESS_BEG, '-SNP_SESSION '. SESS_END), 60) as char)

  I would like to know if that's what you're looking for.

• Compare two date columns

  Hi, Vanessa,.

  If d1 and d2 are the two DATE columns:

  SELECT     *     -- or list whatever columns you want to see
  FROM     table_x
  WHERE     d1 != d2
  ;
  

  Displays all the lines where they are declared, but not the same thing.

  If you want to include the lines where one of them is null, but the other is not:

  SELECT     *     -- or list whatever columsn\ you want to see
  FROM     table_x

• Value of the analytical column changing to NULL in RDF

  Hello everyone.
  
  For the column in the existing query in RDF, which is used by one of the analytical column as a source.
  If the request is get changed according to the requirement of bussiness, the source of the analytical column evolves with the NULL value.
  
  Is there a way do not allow this change in RDF. Because many changes of the query are done. And it consumes a lot of time to change sources of the used analytical columns.
  
  Appreciate your help.
  
  Thank you.

  In general, this shouldn't happen. You defined ALIAS' are appropriate for the column that inspired the summaryitems?

• Adobe sign - added two signatories, only shows don't not signatures

  Hello world

  I am the 14 day trial to test and thought that I had a good time until I tried to add two signatories.

  Here's the situation:

  One is e-mail client. They are required to initial 1st page and add the signature on page 2. Which works very well.

  Signatory 2 it's me, via the link 'Add me '. Added the first box for me, made sure I chose my own email to associate with and also Conditions do not show up to the first person the TWO initials and sign on their part put the same conditions on the area of signature for me, once again, manufacturing, be sure to choose my own email address that signing.

  The results after sending.

  Signature and initials of the client work very well.

  When I connect trying to make my initials and signature, the document has an extra page with a box of generic signature and without access to the pre-installed signature and the original boxes that I created.

  What is the problem?

  Thank you!!

  Hi adamh89361894,

  Could you please share the screenshot of the Signature block that is added at the end of the document also the screenshot of the Adobe account sign-> account-> account-> the Signature preferences page settings.

• How to compare data from the two table column by column and connect the result compared to the separate table

  Hello experts...

  I'm new to this forum and Oracle coding complex.

  I have a task in which I want to compare two tables with the same structure, same columns. My Oracle database is 11g Release 2. I want this column-by-column comparison and save the result in a separate table. (say result_table)

  The structure of the table would be as follows:

  SQL > desc emp;

  Name                                      Null?    Type

  ----------------------------------------- -------- ----------------------------

  EMPNO NOT NULL NUMBER 4

  ENAME VARCHAR2 (10)

  JOB                                                VARCHAR2(9)

  MGR                                                NUMBER(4)

  HIREDATE DATE

  SAL                                                NUMBER(7,2)

  COMM                                               NUMBER(7,2)

  DEPTNO NUMBER (2)

  SQL > emp_comp desc;

  Name                                      Null?    Type

  ----------------------------------------- -------- ----------------------------

  EMPNO NOT NULL NUMBER 4

  ENAME VARCHAR2 (10)

  JOB                                                VARCHAR2(9)

  MGR                                                NUMBER(4)

  HIREDATE DATE

  SAL                                                NUMBER(7,2)

  COMM                                               NUMBER(7,2)

  DEPTNO NUMBER (2)

  Both of the tables EMPNO is the primary key.

  I want to compare these two tables based on the EMPNO (EMPNO even is both tables).

  The result log table would be as follows:

  SQL > create table result_table

  2 (check_sr_no, number (5),)

  table_name 3 varchar2 (30),

  ROW_ID 4 varchar2 (20).

  column_name 5 varchar2 (20).

  6 column_data varchar2 (1000).

  compared_by 7 varchar2 (10));

  Table created.

  SQL > alter table result_table

  2 Add the constraint result_table_pk

  3 primary key (check_sr_no);

  Modified table.

  The name of the table and the name of the column will not be hardcoded (based parameter by user)

  I tried to use the dbms_comparison package, but do not find comparison of column to column.

  I also used by using the query operator LESS. It's showing the difference in rank.

  I also went to https://asktom.oracle.com/pls/apex/f?p=100:11:0:P11_QUESTION_ID:2151582681236

  Your help will be very appreciated.

• Use of analytical columns?

  In general, this kind of thing is easily obtained in Excel where you can calculate values in a column of output based on the input values. I need to do this in the reports. I use (generator of reports version 6.0.8.27.0) reports 6i

  
  

  I have a relatively simple question where I'm out of values (heads) and then I need to display the sum on the next line. Let me explain with an example:

  ID Start Date End Date column 1 column 2

  =============================================

  1 1 JANUARY 2010 TO 30 JUNE 2010 120 0

  2 1 JULY 2010 TO 31 DECEMBER 2010 200 120

  3. ON JANUARY 1, 2011 30 JUNE 2011 115 320

  4 1ST JULY 2011 31 DECEMBER 2012 300 435

  5 1 JANUARY 2013 TO 30 JUNE 2013 100 735

  As you can see that the 2 column is derived by adding the previous values in column 1 and appear on the next line.

  So for ID = 4, column 2 = 120 + 200 + 115 = 435 and ID = 5, column 2 = 120 + 200 + 115 + 300 = 735.

  When I use columns in summary, I do not get the desired result.

  I could technically create a formula column and a column of support in place and re - question results but I was hoping to avoid another SQL when the data has already been retrieved. Any ideas or pointers would be greatly appreciated!

  Thank you
