  I have customized a widget and want to reuse on another page. How save, copy or reproduce them? With the help of the iMac and Muse 2015

  You can just copy/paste the enchilada itself on another page, pretty easy!

  If you want to reuse more often, you can open the library or libraries CC , to store and later hanging out once again. Note: for the creation of an article in the 'old' library, you must select the element on the page and click on the new icon in the " library " window To create an element of CC libraries , you can simply drag something in and out of the window libraries CC .

• How to copy a set of tables of one database to another periodically?

  We have a 4 node RAC primary (10.2.0.2) database with a standby (10.2.0.2) Physics on our production site. Offlate we noticed one of the applications (APP2) is the primary origin of loads downloads data on database servers. Our primary database has 2 diagrams,
  (1) including the main schema with all the objects (USER1)
  (2) and the other has views who question some sets of tables of the main schema. USER (2)
  
  The application APP2 uses USER2 views to search and download huge data periodically. We must be able to give the results of accurate data to APP2, but at the same time, take off the charge of the database, as APP2 is not our main of the application.
  
  We would like to know whether there are cost-effective options in oracle to do this, and if so, what would be the best solution? Does anyone have any experience setting something like this before?
  
  We thought to create an another 10.2.0.2 databases to a different server and giving him regular updates (such as streams) database active. The current data in the database changes quite often, so data flows will have to be done often to keep up-to-date data on the new database. So we are not exactly sure how to in this regard. A COPY command would help?
  
  Please advice.

  If you have new servers that you are not currently using why not add these existing RAC cluster servers? Everything can stay in the same database, if you do not have to worry about replication, the change tracking, monitoring of additional databases, etc. And all applications would be able to use this new hardware.

• How to store data instead of memoryengine to the database when using XML file

  Hi Experts,
  
  
  I doubt that in XML for transferring data from the database.
  Transfer of data from XML to the database tables will be store in memory for xml files, my goal is instead stored in the memory table engine
  is it possible to store the data in the database itself...
  I guess that when the size of the data increases say for example given huge amount, store as much data is the big issue here on the right, so to avoid this, is it possible to store
  These data directly in the database level.
  
  Please understand my requirement, either I have the explanation regarding my requirement and please help me how to do this job...
  
  
  THX,
  Sara.

  Remove the dp_doc = option Y of your url. It removes the schema whenever a new connection is created.
  If you don't want to truncate the tables, I think you should also add the option dp_tbl = N.

• Add dynamic lines to Table with the new access property

  Hi all

  I have a scenario where:

  1. I have a chart with lines including the readOnly property.

  2. I want to dynamically add a new row to the table, and this new line should be writable.

  3.I have added the following line in the click event of the button that adds a new line.

  form1.Table1.Row1.access="";
  

  But in the output line is added that is not writable.

  If we add

  form1.Table1.access = "";
  

  then new line is added, but it changes the access of all to the writing table.

  I want to change the access of the newly added line only and not the existing lines.

  How can do us?

  Thank you and best regards,

  Nikhil

  Hi Nikhil,

  Please refer script below, it would be useful to you...

  You must insert the script on the click event of the button below...

  Form1. Page1.Table1.Row3.instanceManager.addInstance (true);

  var countVal = (form1. Page1.Table1.Row3.instanceManager.Count - 1);

  xfa.resolveNode ("form1. Page1.Table1.Row3 ["+ countVal +"]. TextField1") .access ="open ";

  xfa.resolveNode ("form1. Page1.Table1.Row3 ["+ countVal +"]. TextField2") .access ="open ";

  xfa.resolveNode ("form1. Page1.Table1.Row3 ["+ countVal +"]. TextField3') .access = "open";

  This is what my table looks like.

  

  If it does not please let me know vl share the file.

  Thank you

• How do to copy and paste a table from PDF to Excel using AcrobatX

  How to copy and paste a table of PDF to Excel using AcrobatX?

  I was able to do it easily using acrobat 9 but cannot do it in Acrobat10.

  Has the fgone option, or am I missing something?

  I found that the "selection of export that" both the functions 'copy with formatting' were able to go directly to Excel without using a Word, although it also works. The key in Excel is simply use ctrl + v to paste, do not right click and try to use a special dough or the default value, which went to "keep text only".

• How to compare the length of the data to a staging table with the definition of the base table

  Hello
  I have two tables: staging of the table and the base table.
  I get flatfiles data in the staging of the table, depending on the structure of the requirement of staging of the table and the base table (length of each column in the staging table is 25% more data dump without errors) are different for ex: If we have the city long varchar 40 column in table staging there 25 in the base table. Once data are discharged into the intermediate table that I want to compare the actual length of the data for each column in the staging table with the database table definition (data_length for each column of all_tab_columns) and if no column is different length that I need to update the corresponding line in the intermediate table which also has an indicator called err_length.
  
  so for that I use the cursor c1 is select length (a.id), length (b.SID) of staging_table;
  c2 (name varchar2) cursor is select data_length all_tab_columns where table_name = 'BASE_TABLE' and column_name = name;
  But we get atonce data in the first query while the second slider, I need to get for each column and then compare with the first?
  Can someone tell me how to get the desired results?
  
  Thank you
  Manoi.

  Hey, Marco.

  Of course, you can set src.err_length in the USING clause (where you can reference all_tab_columns) and use this value in the SET clause.
  It is:

  MERGE INTO  staging_table   dst
  USING  (
         WITH     got_lengths     AS
                   (
            SELECT  MAX (CASE WHEN column_name = 'ENAME' THEN data_length END)     AS ename_len
            ,     MAX (CASE WHEN column_name = 'JOB'   THEN data_length END)     AS job_len
            FROM     all_tab_columns
            WHERE     owner          = 'SCOTT'
            AND     table_name     = 'EMP'
            )
       SELECT     s.ename
       ,     s.job
       ,     CASE WHEN LENGTH (s.ename) > l.ename_len THEN 'ENAME ' END     ||
            CASE WHEN LENGTH (s.job)   > l.job_len   THEN 'JOB '   END     AS err_length
       FROM     staging_table     s
       JOIN     got_lengths     l     ON     LENGTH (s.ename)     > l.ename_len
                           OR     LENGTH (s.job)          > l.job_len
       )     src
  ON     (src.ename     = dst.ename)
  WHEN MATCHED THEN UPDATE
       SET     dst.err_length     = src.err_length
  ;
  

  As you can see, you have to hardcode the names of the columns common to several places. I swam () to simplify that, but I found an interesting (at least for me) alternative grouping function involving the STRAGG user_defined.
  As you can see, only the subquery USING is changed.

  MERGE INTO  staging_table   dst
  USING  (
         SELECT       s.ename
         ,       s.job
         ,       STRAGG (l.column_name)     AS err_length
         FROM       staging_table          s
         JOIN       all_tab_columns     l
        ON       l.data_length  < LENGTH ( CASE  l.column_name
                                            WHEN  'ENAME'
                                  THEN      ename
                                  WHEN  'JOB'
                                  THEN      job
                                     END
                             )
         WHERE     l.owner      = 'SCOTT'
         AND      l.table_name     = 'EMP'
         AND      l.data_type     = 'VARCHAR2'
         GROUP BY      s.ename
         ,           s.job
         )     src
  ON     (src.ename     = dst.ename)
  WHEN MATCHED THEN UPDATE
       SET     dst.err_length     = src.err_length
  ;
  

  Instead of the user-defined STRAGG (that you can copy from AskTom), you can also use the undocumented, or from Oracle 11.2, WM_CONCAT LISTAGG built-in function.

• update to column values (false) in a copy of the same table with the correct values

  Database is 10gr 2 - had a situation last night where someone changed inadvertently values of column on a couple of hundred thousand records with an incorrect value first thing in the morning and never let me know later in the day. My undo retention was not large enough to create a copy of the table as it was 7 hours comes back with a "insert in table_2 select * from table_1 to timestamp...» "query, so I restored the backup previous nights to another machine and it picked up at 07:00 (just before the hour, he made the change), created a dblink since the production database and created a copy of the table of the restored database.
  
  My first thought was to simply update the table of production with the correct values of the correct copy, using something like this:
  
  
  Update mnt.workorders
  Set approvalstat = (select b.approvalstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi)
  where exists (select *)
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi)
  
  It wasn't the exact syntax, but you get the idea, I wanted to put the incorrect values in x columns in the tables of production with the correct values of the copy of the table of the restored backup. Anyway, it was (or seem to) works, but I look at the process through OEM it was estimated 100 + hours with full table scans, so I killed him. I found myself just inserting (copy) the lines added to the production since the table copy by doing a select statement of the production table where < col_with_datestamp > is > = 07:00, truncate the table of production, then re insert the rows from now to correct the copy.
  
  Do a post-mortem today, I replay the scenario on the copy that I restored, trying to figure out a cleaner, a quicker way to do it, if the need arise again. I went and randomly changed some values in a column number (called "comappstat") in a copy of the table of production, and then thought that I would try the following resets the values of the correct table:
  
  Update (select a.comappstat, b.comappstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi - this is a PK column
  and a.comappstat! = b.comappstat)
  Set b.comappstat = a.comappstat
  
  Although I thought that the syntax is correct, I get an "ORA-00904: 'A'. '. ' COMAPPSTAT': invalid identifier ' to run this, I was trying to guess where the syntax was wrong here, then thought that perhaps having the subquery returns a single line would be cleaner and faster anyway, so I gave up on that and instead tried this:
  
  Update mnt.workorders_copy
  Set comappstat = (select distinct)
  a.comappstat
  mnt.workorders a, mnt.workorders_copy b
  where a.workordersoi = b.workordersoi
  and a.comappstat! = b.comappstat)
  where a.comappstat! = b.comappstat
  and a.workordersoi = b.workordersoi
  
  The subquery executed on its own returns a single value 9, which is the correct value of the column in the table of the prod, and I want to replace the incorrect a '12' (I've updated the copy to change the value of the column comappstat to 12 everywhere where it was 9) However when I run the query again I get this error :
  
  ERROR on line 8:
  ORA-00904: "B". "" WORKORDERSOI ": invalid identifier
  
  First of all, I don't see why the update statement does not work (it's probably obvious, but I'm not)
  
  Secondly, it is the best approach for updating a column (or columns) that are incorrect, with the columns in the same table which are correct, or is there a better way?
  
  I would sooner update the table rather than delete or truncate then re insert, as it was a trigger for insert/update I had to disable it on the notice re and truncate the table unusable a demand so I was re insert.
  
  Thank you

  Hello

  First of all, after post 79, you need to know how to format your code.

  Your last request reads as follows:

  UPDATE
    mnt.workorders_copy
  SET
    comappstat =
    (
      SELECT DISTINCT
        a.comappstat
      FROM
        mnt.workorders a
      , mnt.workorders_copy b
      WHERE
        a.workordersoi    = b.workordersoi
        AND a.comappstat != b.comappstat
    )
  WHERE
    a.comappstat      != b.comappstat
    AND a.workordersoi = b.workordersoi
  

  This will not work for several reasons:
  The sub query allows you to define a and b and outside the breakets you can't refer to a or b.
  There is no link between the mnt.workorders_copy and the the update and the request of void.

  If you do this you should have something like this:

  UPDATE
    mnt.workorders     A      -- THIS IS THE TABLE YOU WANT TO UPDATE
  SET
    A.comappstat =
    (
      SELECT
        B.comappstat
      FROM
        mnt.workorders_copy B   -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    )
  WHERE
    EXISTS
    (
      SELECT
        B.comappstat
      FROM
        mnt.workorders_copy B
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    )
  

  Speed is not so good that you run the query to sub for each row in mnt.workorders
  Note it is condition in where. You need other wise, you will update the unchanged to null values.

  I wouold do it like this:

  UPDATE
    (
      SELECT
        A.workordersoi
        ,A.comappstat
        ,B.comappstat           comappstat_OLD
  
      FROM
        mnt.workorders        A      -- THIS IS THE TABLE YOU WANT TO UPDATE
        ,mnt.workorders_copy  B      -- THIS IS THE TABLE WITH THE CORRECT (OLD) VALUES
  
      WHERE
        a.workordersoi    = b.workordersoi      -- THIS MUST BE THE KEY
        AND a.comappstat != b.comappstat
    ) C
  
  SET
    C.comappstat = comappstat_OLD
  ;
  

  This way you can test the subquery first and know exectly what will be updated.
  This was not a sub query that is executed for each line preformance should be better.

  Kind regards

  '2' in your question means "to"? If so please do not use text instant message in this forum.

  Now I suppose that PRE_RATING_LEVELS is a table in your application. And you are trying to include this table in an existing query. But in doing so, you have found the Cartesian product, correct?

  In fact, how do you think someone a public forum without any knowledge of your table and data structure could help you?

  Lets see, here's your query. I formatted.

               and pce1.object_id = pce.object_id

  order
      by papf.employee_number 
  

  Now, you want to add the PRE_RATING_LEVELS in the list so that you can use the column NAME.

  First thing you need to do is to determine the relationship between PRE_RATING_LEVELS and other tables. A relationship can be

  1. one on one
  2 one-to-many
  3. - to-several

  So when you tried to join, your state of health has resulted in 2nd or 3rd type of relationship. If you arrive with someone who knows the business and the data and find the table that could uniquely identify a line of PRE_RATING_LEVELS.

  Hi
  
   
  
  Yep, use Index Array as Gerd says. Also, using the context help ( + h) and looking through the array palette will help you get an understanding of what each VI does.
  
   
  
  This is fundamental LabVIEW stuff, perhaps you'd be better spending some time going through the basics.

• How to export data to excel that has 2 tables with the same number of columns and the column names?

  Hi everyone, yet once landed upward with a problem.

  After trying many things to myself, finally decided to post here...

  I created a form in form builder 6i in which clicking on a button, the data gets exported to the excel sheet.

  It works very well with a single table. The problem now is that I cannot do the same with 2 tables.

  Because the tables have the same number of columns and the columns names.

  Here are the 2 tables with column names:

  Table-1 (MONTHLY_PART_1)	Table-2 (MONTHLY_PART_2)
  SL_NO	SL_NO
  MODEL	MODEL
  END_DATE	END_DATE
  U-1	U-1
  U-2	U-2
  U-4	U-4
  ..........	........
  ..........	........
  U-20	U-20
  U-25	U-25

  Given that the tables have the same column names, I get the following error :

  402 error at line 103, column 4

  required aliases in the SELECT list of the slider to avoid duplicate column names.

  So how to export data to excel that has 2 tables with the same number of columns and the column names?

  Should I paste the code? Should I publish this query in 'SQL and PL/SQL ' Forum?

  Help me with this please.

  Thank you.

  Wait a second... is this a kind of House of partitioning? Shouldn't it is a union of two tables instead a join?

  see you soon

• How to insert a record for tables joined

  Hello
  first of all I learned forms for a few days.
  I created a simple form where report columns from two tables to join them.
  Once I entered a new list of values in the fields in the form, how can I insert them in the two tables? What I did, but it does not work, is to "Insert the name of procedure" of the data block = my procedure compiled in "Units of program" in the hope that once pushed the "run query button" in the form running worked, but it did not work.
  Any advice for the best way how perform an insertion in one or more tables with the contents of the form fields?
  
  My versions are: 10gXE and 10.1.2.0.2 forms database
  
  Thanks in advance!

  You can create a trigger INSERTION-IT-in the form and your two inserts here. A more 'clean' approach would be to create a database view and your block based on that point of view. Then create INSTEAD OF triggers on the view to insert the data in the two tables.

  Hello

  If the block is based on your database table, just committed the shape, then changes will be applied to the database.
