• The script generation is not supported for Table with XML or UDT column Types

  I get this message trying to generate a script to create a table with an XMLTYPE column.  We use the Oracle Developer Tools for Visual Studio to generate scripts as SQLDeveloper does still not support TFS integration.  He was always pretty easy to generate scripts and maintain control of source code in this way (with the exception of materialized views).  It was great, just right click and generate a script for the project and check it in.  Unfortunately as the adoption of XML grows, we find passage to the SQL Developer more often to perform tasks not supported and then return to the VS IDE to manage source code control.  Free of any chance that it will be supported in the future?

  Yes, our plan is to support several types as time goes by.

  You possibly can speed things along by voting or by filing a request for new feature here:

• How to recover the large number of columns for all items at once

  I have a table (T1) with a large number of columns (50). I am building a page on which I would like to consolidate these columns in some regions:
  
  Region: has
  Items i1 - i10
  
  Region: B
  I11 - i20 items
  
  Region: C
  I21 elements - i30
  …
  Etc.
  
  The majority of the articles on this page are extracted from the same table (T1). So far, the type of each source element has the value SQL query and each item has the motion of the source is defined as:
  
  SELECT column1 FROM t1 WHERE t1id =: global_item
  
  What is the best practical approach to retrieve values for all items on this page? Is there a way to retrieve all the columns point at the same time, something like:
  
  SELECT column1, Column2, Column3, column50 FROM t1 WHERE t1id is: global_item
  
  Instead of:
  
  I1 point source:
  SELECT column1 FROM t1 WHERE t1id =: global_item
  
  Point source i2:
  SELECT Column2 FROM t1 WHERE t1id =: global_item
  
  Point i3 source:
  Column3 SELECT FROM t1 WHERE t1id =: global_item
  …
  Item i50 source:
  SELECT column50 FROM t1 WHERE t1id =: global_item
  
  For each item on this page, when they are displayed?
  
  Thank you for your time.
  
  Daniel

  Set the source of static assignment type item and delete individual values of source of SQL query. Create a process before the header PL/SQL along the lines of

  begin
  
    select
              column1
            , column2
            , column3
              ...
            , column50
    into
              :i1
            , :i2
            , :i3
              ...
            , :i50
    from
              t1
    where
              t1id = :global_item;
  
  end;
  

  OR

  Create an automated process line go through the wizard for the table T1, then set the Source Type of the database column and the source values for each item in the name of the corresponding column in the T1.

• Add a large number of columns to a shape

  Is there an easier way to add a large number of columns to a form of how I do it?
  What happens in general I find that a bunch of columns must be added to the table, what I do in the database. So I need to get these
  columns added to an existing form. As I do that is to create a new block in the form of referencing the same table, just like the old block.
  Delete all the columns in the new block that were in the old block.
  Move all the triggers of old block of the old block to the new block. Move old items to the old block of the newblock.
  Search for old block properties where clauses or whatever and who recreate in the new block...
  and then delete the old block and rename the new block to the old name of block.
  Phew! A lot of potential for error here.
  I need to possibly adjust the canvas for items and of course to reorganize things.
  
  Is there a better way?
  
  (BTW it's forms 11.1.1.4)

  Maybe create a routine of jdapi to compare the elements of a block known based on a table with the data dictionary ( user_tab_cols )? As each piece of information is given in the database (data type, the column name,...) should not be too difficult to implement.

  Hello

  I have a concrete example of this issue, I tested in my environment. Please follow the steps below to install this on your databases.

  My global_name to database source is: REP102A. WORLD

  Target Table: MERCHANT NAVY. ORDER_ENTRY

  Replication will happen as follows:
       
  ORDERS. ORDER_ENTRY (REP102A)-> SHIPPING. ORDER_ENTRY (REP102B)

  Your friend won't. Don't listen to him any more. Mode of disposal creates

• Reading a CSV with a large number of columns

  Hello

  I tried to read data from files large csv with 38 columns by reading a line using readline and scan using the scan linebuffer.

  The file size can be up to 100 MB.

  Scan does not seem to support the large number of areas.

  Suggestions to the comma separated fields 38 reading. There is a header row in the file.

  Have you considered the use of the modifier "rep"? You can find examples in help, search for 'chain with real table ASCII Comma-separated numbers '.

• Add a table with the number of lines and columns JS

  Hello

  Simple question: what is the syntax for adding a table with a specified number of rows and columns? I don't get it. (I don't know how to add them later, but I want to do when I create the table). Here is the entry in the ESTK:

  Tables.Add (to: LocationOptions, reference: all, withProperties: Object): array

  Creates a new table.

  (optional): Data Type: LocationOptions, by default: LocationOptions.UNKNOWN
  The location of the new table to the object within the container object or reference. (Optional)

  Reference: Data Type: no
  The reference object. Note: Required when the value specifies before or after. Can accept: Table, XmlStory, XMLElement, TextFrame, text, character, Word, line, paragraph, TextColumn, PointInsertion, story, cell or TextStyleRange. (Optional)

  withProperties: Data Type: object
  Initial values for the properties of the new Table (optional)

  Thank you

  Ariel

  After much experimentation, I found this works:

  t = app.selection [0].tables.add (LocationOptions.AT_BEGINNING, undefined, {columnCount:2, headerRowCount:1, bodyRowCount:5, footerRowCount:3});})

• Select tables with a number of corresponding columns

  Hi guys
  
  I need to find a list of tables with columns in common.
  
  So basically I need a list of tables and tables that have 3 or more column in common with her, and what are these columns.
  
  This could take the form of pairs of tables, IE table A table B on columns 1,2,3 games
  Table of an array of matches C on columns 1,3,4
  
  or it could be games table A table B and C columns 1,2,3 etc.
  
  I think I do with PL/SQL, what I can do - but I was wondering if this kind of thing is possible with just an SQL statement - if any of you have done it before and you have some SQL, which would be a great help.
  
  Thank you very much
  
  Scott

  Well, most of the work is done.
  'Just', you need to add an aggregation function to present the list of corresponding columns.

  In 11.2, it has LISTAGG:

  SELECT a.table_name tab1,
         b.table_name tab2,
         count(*) match_count,
         listagg(a.column_name,',') within group(order by a.column_id) col_list
  FROM user_tab_columns a
       JOIN user_tab_columns b ON a.column_name = b.column_name AND a.table_name != b.table_name
  GROUP BY a.table_name, b.table_name
  HAVING count(*) > 2
  ;

  Now, I wanted to update the table such that all ID columns are updated with running number.
  
  Each ID columns should get incremented so that, for Country_ID column corresponding to "India" If country_id is 1, that there must be one for all the lines with the name as "India". Likewise for "Australia".
  
  In the case of State, she also has the same logic with numbers repeated until the very name of the State comes.
  
  For the city, it of course will hold separate ID only because the name of the city will not get duplicated.
  
  This update must be done in the normal way using simple SQL such as no PLSQL don't like looping, etc... is involved.
  
  Here are the contents of the table, and that's how the table should be updated,

• Performance issues with large number of nodes

  I am creating an application to display graphics (large), for example:

  

  But I ran into some performance issues, even for a relatively small number of nodes in the scene graph (+-2000 in the picture above). The graph is built, step by step, adding circles and paths to a StackPane. Circles and paths can be semi-transparant. For a small number of nodes, I get a solid 60 FPS, but this decreases over time to about 5 frames per second. As soon as I stop adding new nodes, the framerate shoot again up to 60 images per second. The framerate drop even when all the nodes are outside the viewport.

  My questions are:

  * Is Platform.runLater () call to 2000 times a minute too?

  * This might just be a problem with my graphics card? (I have an Intel HD Graphics 3000)
  * JavaFX pulse recorder says such things, are there meaningful information in that I'm missing?

  PULSE: 1287 [163MS:321MS]

  T14 (0 + 0ms): col of CSS

  T14 (0 + 5ms): layout pass

  T14 (6 + 152ms): waiting for the minutes of the previous

  T14 (158 + 0ms): copy the State for graphic rendering

  T12 (159 + 0ms): dirty opts calculated

  T12: Path of the slow form for null

  T12 (159 + 160ms): painted

  T12 (319 + 2ms): Presentable.present

  T12 (321 + 0ms): completed the presentation of painter

  Counters:

  Background image of the region used cached: 14

  NGRegion renderBackgroundShape slow path: 1

  Nodes displayed: 1839

  Nodes visited during rendering: 1840

  Kind regards

  Yuri
  

  Basically, try some optimization of performance ranging from the simple to the complex.   Each of the changes below may provide you with an increase in performance.  Some will probably increase performance much more that others (depending on where is the real bottleneck).  I would probably start by replace the paths to the lines and reduce the number of Platform.runLater calls (as adding nodes that fall within the viewport can be difficult only).

  > The framerate drop even when all the nodes are outside the viewport.

  Place the nodes in the graph, which fall inside the viewport.

  > Is Platform.runLater () call to 2000 times a minute too?

  Yes, there is no reason to call it more than 60 times a minute when the framerate of JavaFX is capped at 60 frames per second by default.

  > This might just be a problem with my graphics card? (I have an Intel HD Graphics 3000)

  Yes, it's a graphics system relatively low-end.  But, look at the comment of developer below - your CPU and choice of graphic primitives can also affect rendering speed.

  > Adding circles and the paths to a StackPane

  You don't need a StackPane to this, a group is a container easier and probably better.

  > may be semi-transparant

  Remove transparency * may * cause acceleration.

  ----

  You run may be:

  https://JavaFX-JIRA.Kenai.com/browse/RT-20405 : improve the rendering of path performance

  Maybe if you use lines rather than the paths, performance might improve.

  A comment by a developer on this performance tweak application is:

  «It is quite normal for applications that use arbitrary paths (if the node path objects, SVGPath, polyline, or polygon) because these paths are rendered in software.» As card circle, Ellipse, line and Rectangle very primitive forms easily to the operations that can be performed entirely on the GPU, which makes them essentially cheap. There is no need to compare the rendering of a complicated shape for rendering of simple primitives for this reason. »

  ----

  Setting the cache indicators can help, but probably only if you animate nodes.

  ----

  Present level of detail of your graph functionality so a chart with zoom out is not make as many nodes as a part of zoomed in.

  ----

  You run any code important calculation on the JavaFX application thread that could stall it?

  Can make you available a ftom so that others can reproduce your problems?

• How to work with large number of files to a cloud export in Adobe's PDF format

  I have about 1000 PDF files to be converted to Excel.

  What means are optimal (i.e. with less manual intervention) in which I can do these tasks:

  * Download

  * convert

  * Download

  Pointers to a link will be useful. The FAQ page doesn't have this info: FAQ | Export of Adobe PDF

  I found a way to download it via a web browser and convert them via a web browser (with the help of pointing and clicking in the GUI). These methods REQUIRE the browser to be open so that the download and conversion happens - and this leads to frequent crashes / freezing of the browser windows while download / convert several files at once.

  How background sync (i.e. as in Dropbox or box etc, in which I save the files in a folder and it automatically syncs in the background) for uploading / downloading files?

  It would be great if someone can point out a optimal workflow / recommended for (conversion) handling a large number of PDF files using Adobe Document Cloud export in PDF format

  There is no best or recommended workflows. It is not designed for $ 20. Not even the product of Acrobat $500 would be 1000 PDFs without pain, but it would be a little better.

  TYPEN in table1 to be inserted in REFERENCE in table0, but by a function that transforms it to another value.
  
  
  There are several other tables like 'table1', but with slightly different columns, which must be inserted into the same table ("table0").
  
  The amount of data in each table is pretty huge, so the procedure must be made into small pieces and effectively.
  
  If / could I use data pump for this?
  
  
  Thank you!

  How can I continue with this then?

  Should I delete the columns I don't need and transform the data in the first table, and then use data pump.

  or should I just do a procedure traversing all ranks (into small pieces) "table1", then threading "table0"?

  You have two options... Please test both of them, calculate the time to complete and to implement the best.

  So I have a link data table as in:
  

  describe links ;
   Name                            Null?    Type
   ----------------------------------------- -------- ----------------------------
   ID                                  NUMBER
   NETWORK_ID                             NUMBER
   BEG_NODE_ID                             NUMBER
   END_NODE_ID                             NUMBER
   GEOM                                  MDSYS.SDO_GEOMETRY
   LENGTH                              NUMBER(9,3)
   SPEED_LIMIT                             NUMBER(3)
   DETAIL_LEVEL                             NUMBER(3)
   IN_SYNCH                             NUMBER(1)
   CREATED                             DATE
   MODIFIED                             DATE
   CREATED_BY                             VARCHAR2(30)
   MODIFIED_BY                             VARCHAR2(30)
   MODSTAMP                             TIMESTAMP(6)

  Table is not partitioned and currently has about 69 million lines. ID, Network_id have your clues of normal base on them.
  geom has a spatial index. So I guess my question is I'm starting to push the limits here for the performance of the spatial index?
  In another thread here, I read something that oracle will not use a spatial index for certain types of transactions?
  
  The geometry that is recorded in each line is G_TYPE 2002 (line or curve) for example:
  

  SDO_GEOMETRY(2002, 8307, NULL, 
  SDO_ELEM_INFO_ARRAY(1, 2, 1), 
  SDO_ORDINATE_ARRAY(
  -97.35263, 
  32.70169, 
  -97.35277, 
  32.70178, 
  -97.35301, 
  32.70185, 
  -97.35319, 32.70186,
  -97.35347, 32.70184)
  )

  Then John gave me this answer really great to know how to look for a point in a using bounding box of the:

   
  sdo_inside(geom, [create a 2003 geometry to describe a rectangle]) 

  function. Now since this line is a series of points, can one still use the sdo_inside or would be:

   sdo_anyinteract(geom,[create a 2003 geometry to describe a rectangle]) 

  function is best?
  
  Thanks in advance.

  Its a small example. I had not to build your dashboards and the sdo_geom_metadata and the spatial index, I used the SDO_GEOM. RELATE to the function rather than the space operator. The result is the same:

  --test relation line with point (second vertex of line)
  --  INSIDE
  SELECT SDO_GEOM.RELATE
   (SDO_GEOMETRY(2002, 8307, NULL,
      SDO_ELEM_INFO_ARRAY(1, 2, 1),
      SDO_ORDINATE_ARRAY(-97.35263,32.70169,-97.35277,32.70178,-97.35301,32.70185,-97.35319, 32.70186,-97.35347, 32.70184)),
    'INSIDE',
    SDO_GEOMETRY(2001, 8307,
      SDO_POINT_TYPE(-97.35277,32.70178,0), NULL, NULL),
    0.01
   ) rel FROM dual;
